TravelTranscript
00:00Today we are at the beginning of a historic discovery. We are going to spend 8 days in
00:04total darkness to explore the exact depth of Krubera Cave, which scientists consider
00:09to be the deepest cave in the world. We are even hoping to discover new animal species
00:13that have been isolated in this subterranean world for millions of years. During this expedition
00:18we are going to cover a distance of almost 5 km and every one of us will lose 10 kg on
00:23average. Curiosity brought me here but it is too risky. Let's descend to the deepest
00:28point of the world's deepest cave. The explored part of Krubera is 2,199 meters deep, but its
00:33true depth is still a mystery. The last update to its map was over a decade ago.
00:38Now I am going to secure myself. I am going to put this Jumar here to be secured again.
00:47I am going to tie this new station's rope to put my stop-descender to descend further.
00:54I am good to go. I will take this securing point off.
01:00Jumar and take it off. Time to descend.
01:05At the cave's deepest accessible point, there lies a dangerous siphon never passed until now,
01:10yet our goal with the Russian speleologist team is to push further. I even signed a contract
01:15accepting that this expedition could literally cost me my life. For over 20 years, Crimean
01:20Federal University Lecturer Gennady Samokin has worked on this cave.
01:24The hardest part is always the entrance part. I have been training for over a year to join
01:28this expedition and document it. During these shoots, I will come face to face with life-threatening
01:33situations on four separate occasions. Time to connect to this station. I'm going to secure
01:39myself first. Now I am connected to two securing points. Any mistake can be fatal. That's why
01:48we use three securing points. Deep slippery wells, tight squeezes, siphons where there is no air,
01:54and freezing temperatures. That's what we're about to face. It's time to take this off and then
02:00this off. We are going to descend. Hello, Krubera. Pitch darkness. Free! These hooks and ropes
02:15you see are from previous expeditions. For more than 60 years, speleologists from around
02:20the world have come to Krubera with no one yet measuring the exact depth of the cave. There's
02:25a real danger of rock falls and sudden floods. Be careful with the rocks here. Even the most
02:30experts have lost their lives here for these reasons.
02:39With the help of Nvidia Studio and GeForce RTX GPUs, we've brought the first ever detailed
02:433D map of Krubera cave to life. More on them later, but on this map you can see five main
02:48camps at different depths of the cave where we'll sleep. The camps are set up in a way that
02:53they are only 8 hour moving distance far from each other. We move 8 hours a day, then rest.
03:01Just because we're descending one after the other doesn't mean it's only us. We're actually
03:05a team of two groups, 11 people in total. And right at the beginning I started to tangle
03:10myself. Because of confusion I forgot to put my stop descender on and carelessly unlock
03:19my most vital securing point. Now I'm relying on the Jumar, the weakest securing point. It
03:28works fine as long as I stay upright, but if I squat a bit too much it fails.
03:32I forgot one thing. I need to adapt quickly if I want to make it out alive. I'm gonna put
03:43my securing point because I forgot to put this under. Alright. When you're on the rope, it's
03:51just you and the rope. You're all alone. Nobody can see the mistakes you could make and really
03:55help you.
03:56Whoa. This paddle got away from me. I need to put it back on. If I fall from here, I don't
04:14think I'm gonna be alive.
04:16The average speed of moving through the cave is 100 meters per hour. Our ascending speed
04:21and descending speed are the same. We also carry our bags with us in the cave.
04:26The temperature is only 3 degrees Celsius, so being here is not different from being inside
04:31of a giant fridge.
04:32Hey man. Hey, how are you? Nice.
04:37You feel cold already? Not yet.
04:41You okay?
04:43No. This is where a sheep met its tragic end, falling from the lush valley above down hundreds
04:50of meters into the darkness below.
04:52The sheep is under the soil. They covered it because they wanted to prevent the smell.
04:57Now we are about to get through a tight squeeze. As its name suggests, you have to make yourself
05:01as small as possible and crawl inside.
05:03Let it crawl. I'll go after it.
05:08Oh my god. How do I do this? I have to go sideways like this.
05:21Krubera Cave is in the Arabica Massif of South Caucasus, 15 kilometers away from Black Sea.
05:29Arabica is one of the largest and highest limestone formations in the mountain, providing an ideal
05:35environment for the development of such an immense cave.
05:40The cave was formed and carved by underground streams and rain, creating both massive, steep
05:44wells as well as narrow, long tunnels.
05:49Make myself smaller.
05:57Scientists believe Krubera is 5 million years old and it continues to be shaped even today.
06:03These squeezes are very hard.
06:10They say, don't feel claustrophobia until you get stuck.
06:22Just because you are a nature person, don't come here to a place like this.
06:28Especially to Krubera Cave, where Earth welcomes you with its narrow meanders.
06:37Do you see the marks on the side walls?
06:39At this point in the cave, the passage was so narrow that they had to use tools to break
06:43the rocks and widen it.
06:45When we pass through narrow passages, small particles fill the air and make it hard to breathe
06:50as they get into our mouths.
06:52Also, our legs get cramped quickly from working the same muscle group.
06:57It's better if you go slow.
07:07Alright.
07:08Here you can see the wire.
07:11This wire goes for 2,000 meters.
07:13Yes.
07:14And allows the foam to work.
07:16Unfortunately, it's not broken somewhere.
07:19It was likely damaged by a recent flood.
07:22We're completely cut off from the outside world for the next 8 days.
07:29We have two possible ways here.
07:31Yes.
07:32And there is an arrow on the wall that shows the correct way.
07:44That's the way to go.
07:46Oh, yeah.
07:47I'll take a little arrow.
07:49Go.
07:50Go.
07:51I'll go.
07:53If you can see the wire is on the wall.
07:55Ooh.
07:56Ah.
07:57Very nice man.
07:58U.
08:00Ooh.
08:01Ah.
08:02The mirror of man.
08:03Ah.
08:04Ooh.
08:05Shit.
08:06It's useful for the transfer bags.
08:09So you don't have to carry the weight of the bag, Rob carries it for you.
08:15You move it like this.
08:16Yeah.
08:17Falling through these rocks could injure us.
08:24Okay, we have to be connected to the rock as well.
08:29You don't want to be... I want to cut the stuff like so.
08:32You don't want to be... I want to cut the stuff like so.
08:36I was almost going to fall.
08:38This thing saved me.
08:40It's so wet, it's slippery.
08:42Looks like it's zipline.
08:47I just assumed that. It's not dangerous.
08:50Alright.
08:56The big whale's pass.
08:58How do you feel, Odek?
09:00I took the pill, so it's easy enough.
09:02What type of a pill?
09:04A pail pill.
09:05It has been a long way.
09:06We're about to arrive at the first camp.
09:08If you see, this is the big whale.
09:11105 meters.
09:20It feels like it's three times bigger.
09:23Thinking about ascending two kilometers back to the surface
09:26makes me feel overwhelmed already.
09:28The rope fibers got stuck in the stop-descender mechanism.
09:31If I couldn't get them out, I would have to leave the stop-descender here,
09:35and I wouldn't be able to go down any further.
09:37I would have to quit and climb back up.
09:41This panic caused me to tangle my rope and my bag's rope.
09:56Free.
10:00We get about 70% of this whale.
10:03Which is like, how many meters?
10:0580 meters, I guess.
10:06This place is really scary now.
10:13My headlamp does not even lighten up beyond my shoes.
10:16All I can see is endless pitch darkness, which makes me a bit uneasy.
10:19At least it helps me stay focused on what's right in front of me.
10:22It's all about having a little weight.
10:27Yeah, I can do this.
10:35It shocks the rope.
10:37Intense shock loads on the ropes from sudden falls like these can break the rope because of the high tension.
10:42It can also seriously damage my spine.
10:48But it doesn't go very smooth.
10:51I can do it.
10:57So, welcome to the mother of the whale.
11:01Alright.
11:02While we were descending into a huge well and filming everything,
11:05the first group created a gap between us.
11:07Wait, I don't know what's in here.
11:09But I don't fit here.
11:16I'm too large.
11:23Look at all the rocks.
11:24I think they dropped from the ceiling.
11:26If you camp here, one of these rocks can fall on us.
11:31There's a sign here.
11:32Yes, it says don't put your mess in here.
11:35Take your mess to the surface.
11:37The mess means, well, before there were flashlights,
11:42people used carbide lamps.
11:45Waste from all the era lamps.
11:49Being the center of interest of speleologists,
11:51Krubera has intrigued some daring scientists since the early 20th century.
11:55After just 10 hours in the cave,
11:57our eyes are bloodshot and our faces are covered with mud.
12:00My clothes cling to me, soaked with sweat.
12:03We managed to descend another 150 meters more
12:06and finally made it to our first camp.
12:08We're currently at minus 350 meters from the surface
12:11after a solid 12 hour descent,
12:13while some of the experienced cavers in the team
12:15went straight to camp minus 700.
12:17Hurry up, crawl.
12:19Hurry up, crawl.
12:20Where could I put this?
12:29Hang it over there.
12:30Got it.
12:31Like drying them off in the sun, huh?
12:34Yeah.
12:35Gennady is very optimistic about the possibility
12:38of discovering a new animal species at the bottom of the cave.
12:41I can't stop wondering what we will discover.
12:44My boots on fire.
12:46Is that your boot?
12:48Take this one.
12:50We should put the kettle on.
12:52Let's warm up the tent first.
12:54Then dry our socks.
12:56Now everyone is busy drying out their damp clothes
13:00and repairing their gear.
13:02We're gonna eat some snacks.
13:04It's really cold.
13:05Especially when we sit down,
13:07we can feel more cold from the ground.
13:10Change our clothes and we will drink this soup,
13:13eat some pasta,
13:14then sleep hopefully not get frozen.
13:17The most important things are food and fuel for heating, of course.
13:23Speleologists spend the maximum amount of calories,
13:27up to 8,000 kilocalories a day.
13:30It's impossible to fulfill the calories.
13:32That's why I say nutrition is very important.
13:34Everything I wore has gotten wet
13:36and I need it dry by the morning.
13:38We have sleeping bags that keep us warm down to minus 10 degrees Celsius.
13:42Morning everybody.
13:43I just woke up and I'm freezing.
13:45I completely lost my sense of time.
13:48After a sunless morning in Krubera,
13:50we shake off our weariness.
13:52He's sipping the fresh water that the cave offers.
14:05Everybody gears up for the descent.
14:07How are you feeling?
14:09Better than yesterday.
14:10I'm feeling a little more combative.
14:12I'm gonna put on my thermal underwear,
14:15then wear this costume,
14:17wear my boots,
14:18my waterproof gloves,
14:20my helmet.
14:21This is my harness.
14:23Hey everybody.
14:24You look like terminators.
14:27Horizontal tunnel.
14:30Then another big well.
14:32115 meters long.
14:34Another tunnel from there,
14:36some ropes down and up,
14:38and horizontal tunnels again.
14:41And then after that,
14:42the last well is 30 meters.
14:44Then we like go a little bit more and find the camp.
14:48I also asked him if we could catch up with the first group.
14:51It will take like about two and a half hours to get,
14:55maybe like less,
14:56but I don't know when they will move out.
14:59Right.
15:00They think we are slow and they want to wait as much as possible.
15:03As much as possible.
15:04If you want to pee,
15:05you have to take all this gear off,
15:07which will take any person about 30 minutes.
15:11If you are in a hurry,
15:12you might pee on yourself.
15:14Sometimes it's a better idea to do so.
15:16Free?
15:17Free.
15:18Let that go.
15:20Which puts me down.
15:21It's not like earth.
15:23It's like an alien planet.
15:24No life here.
15:26Bye-bye.
15:27Bye.
15:28Love you.
15:29Alright.
15:30Good luck.
15:31How are you, sir?
15:32This is Rosie.
15:33Wonderful.
15:34We're completely cut off from the outside world
15:36and on our own down here.
15:38The camp on the surface has no way of knowing directly
15:40if anything goes wrong,
15:41so we have to be extra careful.
15:43Look, there's water here.
15:45They gathered the water from here to the camp.
15:48We've been descending for about six hours today.
15:51We're all pretty wiped.
15:53Oh, the rope is wet.
15:57From now on, all ropes are wet
15:59and the descender's mechanism doesn't slide easily on wet ropes,
16:02causing risky shock loads each time.
16:08Free.
16:10Yeah, there's a tunnel, huh?
16:12He is shaking from the cold.
16:14I asked for another break.
16:16You have to rest, but you cannot rest long enough
16:20to start freezing.
16:22Sometimes you kind of sit,
16:24you turn your light off,
16:26you close your eyes and try to rest,
16:28and falling asleep.
16:29And this is the worst.
16:30You can easily die if you fall asleep.
16:33So no matter how hard it is,
16:35how difficult it is,
16:36you just have to push yourself.
16:38So we've decided to rest at Camp Minus 700 before pushing to Camp Minus 1400.
16:44Here is our home for tonight.
16:46It looks like everyone has gone ahead already.
16:48Our guide is going to prepare some lunch, dinner, whatever it is.
16:51I don't know what time it is.
16:53My brain is so tired.
16:54More tired than my muscles.
16:56We're close to Camp Minus 1400.
17:01Before entering the Minus 1400 camp,
17:04Speleologists created a makeshift water tap using an empty bottle.
17:08The group ahead has also reached their new campsite at Minus 1400.
17:14Why are you pointing at the tent?
17:17It's going to fly off your hand.
17:27Hello dear friends.
17:29We hope everybody is alive and well.
17:32We hope you haven't lost your team spirit.
17:35We believe that you will succeed,
17:38and you will be able to find something.
17:42Something beautiful for this underground world.
17:45We look forward to seeing you soon.
17:48With our love, your friends.
17:55There's nothing like a cold cave shower under a waterfall
17:58to wash off the mud, sweat and exhaustion after days of exploring.
18:02The water is not that cold.
18:03You feel warmer if you get used to it.
18:06Alright.
18:08After a rough sleep,
18:09some are stretching their tired muscles.
18:11Others are putting on their gear.
18:12Everyone is getting ready to dive further into the depths of Krubera.
18:18His knee pads are torn.
18:19He will stitch up new ones.
18:30Baby let off.
18:31Oh.
18:36Everybody let's keep going.
18:37This is the right way.
18:38When moving in the dark, the light from headlamps can sometimes block the other's view.
18:55But bend your goddamn headlight down.
18:58I can't see anything.
19:07That's enough.
19:08I hate this camera.
19:09While I was waiting to descend, my headlamp battery ran out.
19:14My battery is finished.
19:16There's no light.
19:17Luckily, I had spare batteries in my pocket.
19:20At the very bottom of the cave, we did a topographic survey and we recorded everything with the camera.
19:28As we go deeper into Krubera, I wonder how the animals have evolved here in the darkness.
19:32So far, I haven't crossed with any creature.
19:34But it makes me think, where there's water, there's a chance for life to exist.
19:38Cave is so weird now.
19:39In the cave, your biological clock is always off.
19:45Without clock, it automatically switches to 40 hours day.
19:5140 hours day time.
19:52Yes.
19:53So they're awake for 20-something and sleeping for 16-something.
20:00We've reached the halfway point of Krubera Cave, but we still need to descend another 200 meters to get to the next camp.
20:07The cold, tiredness, and being always under artificial light are starting to affect my performance and leading me to make fatal mistakes.
20:14At this point, when I was 50 meters above the rocky ground, I accidentally unlocked my last securing point and realized I had to hang solely by the strength of my muscles.
20:23I forgot putting my descender on.
20:31Every second, my muscles are getting tired.
20:33If I fail to lock my carabiner and fall, I will certainly lose my life.
20:37The way I attach the carabiner is extremely risky, and it could open at any time.
20:42I also got my glove jam.
20:45All right.
20:47It's not looking good.
20:57All right.
20:58It requires full dedication.
21:01One small mistake can kill you.
21:06Now I'm good to go.
21:17Gotcha.
21:18This is a rope I want to be on.
21:23Just a couple of minutes later, I almost unlocked my last securing point for the second time.
21:28I opened the carabiner.
21:30Fortunately, I realized my mistake.
21:32That's not good.
21:34Another mistake.
21:35I need to put my descender first.
21:37My eyes feel heavy in constant darkness, and my brain feels like it's collapsing under the weight of fatigue.
21:43Hey guys, it's really tough.
21:46It's not easy as it looks.
21:50There are underwater currents that block the way.
21:53Siphons are basically passages that are flooded with underground rivers.
21:57Well everybody, let's go and take a dip.
22:02There are dozens of them along our path, and a single wrong move could leave us trapped, out of breath, and facing the terrifying risk of drowning.
22:10To help you better understand the challenging conditions in Krubera, we created 3D models of siphon explorations and the map.
22:16Blender, as with most 3D softwares, is powered by Nvidia Studio and GeForce RTX.
22:22So we work directly in full detail within the viewport, seeing results instantly without waiting for long renders.
22:28On the map, you can see where the siphons begin and end.
22:31These water-filled, deep passages are scattered throughout the cave, and we're now starting with a moderately big one.
22:37Creating these animations took us 2 weeks, but the advanced technology we used significantly sped up our workflow and helped us to save hours.
22:44This caver, as you can see, has attached rocks to himself to prevent floating upwards and striking his body on the ceiling.
22:51He could also be swept away by the water flow and get lost in one of the upward leading passages and lose his life.
22:59Some of the siphons, like this one, have no air pockets, which means these passages are completely filled with water.
23:06Passing through them can take several minutes depending on their length and difficulty.
23:10If you can't follow the rope in the siphons and miss it, you can enter the wrong tunnel and you can drown.
23:15If your clothes get caught on a sharp stone and you can't get it out in a panic, you can drown.
23:19Even if you do everything right, you can still drown if you can't hold your breath long enough.
23:44I went back to the camp at minus 700 after a 6 hour exhausting climb.
23:48I was starting to lose focus from the cold and exhaustion, so the speleologist didn't think it was safe for me to keep going and asked me to wait for them back at camp.
23:56Thankfully, there's enough water and snacks here to keep us going for the coming days.
24:00Oh, these are the mats, huh? Bingo!
24:05The sudden and powerful flooding at camp minus 1640 lifted the leftover mats off the ground, leaving them stuck high above.
24:13It looks like this place was totally submerged.
24:17We didn't know it at the time, but while we were in the cave with no connection with the surface camp, it started raining, which means a real risk of flooding.
24:24The footage you're seeing now is from a few years ago.
24:27As you can see, people barely made out.
24:29Similar floods could destroy our camps and the passages.
24:32Everybody got so wet.
24:34Look how we dry ourselves off.
24:39It's a good idea.
24:41After a wet and chilly night in the cave, the speleologists are preparing their gear for the big days ahead.
24:47They will measure the exact depth of the cave and might even discover new animal species unknown to mankind.
24:54Minus 1640.
24:56Let's get started.
24:58The sharp icicle-like structures hanging from the roof are called stalactites.
25:03These formations grow incredibly slowly, typically less than 10 centimeters in a thousand years.
25:08They form when water drips down and calcium carbonate deposits build up over time.
25:13Is there any space for me there?
25:15Yeah.
25:16The team is extra careful to avoid damaging them.
25:25This looks so dangerous.
25:29They also became both physically and mentally exhausted.
25:37It is too low.
25:38It needs to be higher.
25:39We will hang out more laundry.
25:40Finally, they made it to camp minus 1960, which is the last and the most uncomfortable camp due to its limited space.
25:47Is it okay if I pee on you?
25:49The team was unable to even stand up properly the entire time they were in this small gallery.
25:55The camp is minus 1,960 meters down.
26:00It's one of the deepest camps in the world.
26:02Some of us are soaked entirely and we all have bruised eyes.
26:05Some went down to minus 2,080 already.
26:08The camp, of course, is not very comfortable here.
26:10The flood constantly washes away all the mats.
26:13As for the two captains siphon, it starts about 200 meters down from here.
26:19After days of relentless effort, the team has finally reached the deepest point in Krubera that humankind has ever explored.
26:26Gennady and his teammate are now working to precisely map Krubera's depths.
26:30Measuring the deep underground is much more challenging than measuring the surface as GPS signals are useless.
26:36A laser rangefinder is used which is capable of calculating indirect heights and distances between two points.
26:42He is proceeding to the outermost edge for the exact calculation.
26:47The device has a special compass board and is used with a plastic battery instead of a regular one to reduce magnetic errors.
27:05Not on our left. Not on our right. Where'd it go?
27:08There is no other way.
27:09What?
27:10There is no other way.
27:12I understand.
27:13He has to get wet for this calculation.
27:16Okay.
27:21Once they exit the cave, they will make the total calculation and issue an official statement regarding the cave's actual height.
27:29They are near the two captains siphon, the deepest siphon in the world.
27:33This is the endpoint.
27:34They are preparing the gas tanks to dive into the deepest point of the cave.
27:37Equipped with a precision measurement device to record the cave's depth, Gennady also carries numerous bait traps.
27:43He hopes to discover a new animal species yet unknown to mankind.
27:47We have to be careful here.
27:50Let's see the results. Let's see if anything lives down there.
27:54Now the team is getting inside the siphon's deep, cold and murky waters.
27:59They have already marked some parts of the two captains siphon during their previous expeditions.
28:11But they have had difficulty discovering it entirely.
28:14There are sections that have remained a mystery.
28:16But now their secrets are about to be unveiled.
28:19He tied a few bait trap bottles to the rope so as not to lose them.
28:31On their way back, they didn't notice it.
28:34But the camera captured it.
28:36A small, completely transparent animal was lurking in the water.
28:43Then another animal showed up.
28:44But that also went unnoticed.
28:50What is this?
28:52These animals are blind due to the absence of light.
28:55Fortunately, the team managed to capture an exceptionally unique animal in the trap.
28:59They also encountered another highly distinct looking animal purely by chance.
29:04The footage you're seeing has never been captured before.
29:09There it is. There is the fish. Let's not lose it.
29:12Wow, what is this?
29:14Let's get this one right away.
29:18If these animals are unique to this cave and have never been spotted before,
29:22these findings will be added to the precious library of human knowledge.
29:26A significant step for mankind.
29:28We have documented them on video.
29:30Most of these creatures are transparent as they have evolved in total darkness.
29:35But the other creature they pulled from the trap is not a new discovery.
29:38It was identified in 2013 and it only lives in Krubera Cave.
29:42Its name is Gameras Kruberian.
29:44Amazing news. I'm just in shock.
29:46I'm realizing that we live in a beautiful world.
29:49How do you know, Story?
29:50I'm just kidding.
29:51Depth measurements of the two captains siphon and consequently the cave have also been collected.
29:58Could this discovery confirm Krubera as the Earth's deepest known cave and lead to its inclusion in geography textbooks?
30:04Now it's time to ascend to uncover the truth about Krubera Cave.
30:08Oh my god.
30:09How long do you think we will wait them?
30:14I think like one hour maximum.
30:17We had already put our caving suits back on at the time they had predicted they would arrive and patiently waited for them.
30:23Yeah, I hear them.
30:24They're coming.
30:25Yeah, they're coming.
30:26Woo!
30:27We're getting ready to ascend back up 700 meters in 24 hours.
30:44The ascent is both the hardest part of a caving journey and the stage where most life losses occur.
30:50This phase demands not only significant physical effort but also sustained focus and precise execution.
30:59I hid my head here.
31:01Insects started to appear.
31:04We are really near to the surface.
31:06We took our final break for snacks to regain some energy.
31:09We have a little way to go.
31:12During an eight day caving expedition, the relentless effort of ascending, descending and enduring a constant three degree cold burns an immense amount.
31:19of calories.
31:24Most of us lost around 10 kilograms over the course of this journey.
31:27It's a significant sacrifice we make in the pursuit of new discoveries.
31:30I think this is probably the longest time I've ever been in the cave.
31:35Once everyone exits the cave, Gennady Smokin, the leader of the expedition, will evaluate the success of the eight day mission.
31:41He has a very important announcement to share with the world.
31:44The daylight, the breeze, the fresh air, the rain and the scent of plants restore my sense of humanity.
31:50Finally I see the daylight.
31:54I feel profound gratitude for being alive.
31:59Is that water?
32:00Now, we are about to discover the most important aspect of this documentary.
32:09Can you officially confirm that Krubera is now the deepest cave in the world?
32:14We deliberately didn't publish the depth data of Krubera cave until this interview.
32:19This is a very important moment.
32:20We wanted the collaborative work we've done with you to culminate in a clear declaration that Krubera cave is, as of today, the deepest cave in the world.
32:30The computer calculated the margin of error for us, which was around 0.1%.
32:36Today, we can confidently state that with our methodology, the depth of Krubera cave is 2,224 meters, including the siphon and the upper entrance, which is 3 meters higher than the Arabica Massif.
32:49This means the margin of error is approximately 10 meters.
32:53This year, we also collected samples of crustaceans and sent them for analysis.
32:58You also discovered some creatures during the exploration.
33:02Could you share more information about them?
33:04Have you completed their taxonomic classification or is the research still ongoing?
33:10We discovered some really interesting findings this time.
33:13What is really important is that these data that we have collected are unique.
33:19This is because almost no one has ever worked at such depths.
33:24But their exact species identification is not yet determined.
33:29You might remember that at the end of one of our previous videos, I asked for your support for the Krubera project.
33:35Thanks to your donations, the exploration of Krubera cave became possible, allowing us to film these discoveries and share them with the world.
33:42More than 188 people took part in the making of this project.
33:47Unlike other so-called documentaries on the internet, which often explain already known facts, we documented something entirely new.
33:54This project stands as a true documentary in every sense.
33:57In the future, we are planning to visit Tristan da Gunhut, the most remote settlement in the world.
34:03To get there, we will travel seven days on a cargo ship from South Africa, spend two weeks on the island and return back in seven days.
34:10The nearest settlement there is Saint Helena, which is approximately 2430 kilometers to the north.
34:16But everything related to this project is costly.
34:19Only your supporting support could make this rare documentary come to life.
34:23I also want to thank Nvidia for supporting us creating these animations and maps of the Krubera cave.
34:29With the power of GeForce RTX GPUs, we were able to efficiently handle over 30 hours of RAW footage with unmatched efficiency and share this Krubera documentary with you.
34:39AI-powered video editing with Nvidia's GPUs saves us a lot of time on big projects like this by handling repetitive and time-consuming tasks for us.
34:48As a production team using Blender for 3D modeling and Adobe Premiere for video editing,
34:53RTX GPUs speed up tasks like denoising renders and make 3D rendering incredibly smooth.
34:59Meanwhile, the ray tracing course delivered photorealistic lighting and shadows, bringing our 3D scenes to life.
35:05On the video editing side, RTX GPUs enabled us to improve audio clarity with AI-driven noise reduction, achieve precise color matching for a consistent look, and dramatically reduce rendering times.
35:16GeForce RTX GPUs accelerate over 100 of the world's most popular creative applications, including Adobe Creative Cloud, Blender, Autodesk Maya, Unity, Unreal Engine, and OBS, empowering creators to move from concept to completion faster than ever before.
35:32Thanks to Nvidia for supporting this documentary. Thanks to you for supporting the channel. Ruhi Chenet was here.
35:39Here to watch it!
