就在昨天,Sora又有全新「神作」炸出了!

两位Sora作者,Bill Peebles、Tim Brooks纷纷甩出全新图片。(顺便还秀了一把基友情?)

「一只小熊猫和一只巨嘴鸟是最好的朋友,在蓝色时刻漫步在圣托里尼岛」,Peebles称这个场景简直就和两人走到OpenAI办公室的画面一模一样。

a red panda and a toucan are best friends taking a stroll through santorini during the blue hour

这个视频的连贯性简直令人惊呼:在每一帧中,小熊猫和巨嘴鸟的形象始终保持着一致性。

当然仔细看还是有不少破绽。比如小熊猫的腿有时会交织在一起,画面看起来更像卡通图像,而不像逼真的现实世界。

但总的来说,这种视频质量已经足以让我们对AI视频的未来放飞想象。

有网友立刻做出了配音版,贴切的配音一出,视频更有那个味儿了!

难怪好莱坞大导Tyler Perry直言,自己在看完Sora制作的视频后,直接搁置了自己影师工作室8亿美元的扩建计划!

更多「神作」来袭

这次两位作者放出的第二批视频,效果更加逼真、更加炸裂。

网友们接连不断发出惊叹:Sora是怎么做到一次比一次迭代得更好的?

这个视频是「一名潜水员发现了一艘隐藏的未来沉船,里面有控制论海洋生物和先进的外星技术」。

a scuba diver discovers a hidden futuristic shipwreck, with cybernetic marine life and advanced alien technology

潜水员、海底景观、沉船外壳、内部的外星技术都生成得十分逼真。

当然,这个场景也不是100%完美。立刻有人发现破绽——

比如,潜水员没有摆动脚蹼就能游动起来,也没有吐出气泡。

一位好莱坞电影制片人吐槽说:人的动作看起来没有灵魂,有些像僵尸。

但对于不那么挑剔的观众,这个20秒视频的质量已经够了。

有人满意地说:看起来像《深海迷航》的高分辨率版本

在以往,这个场景无疑要耗费巨资。而现在,好莱坞大片中烧金的高难度场景,都可以用Sora视频替代了,AI淘汰影视行业真不是说说而已!

这条闪着珠光的银色鳞片、有着冰蓝的眼睛和象牙龙角、吐出白气的小白龙,也让网友们惊呼,太太太震撼了!

Close-up of a majestic white dragon with pearlescent, silver-edged scales, icy blue eyes, elegant ivory horns, and misty breath. Focus on detailed facial features and textured scales, set against a softly blurred background

它的拟人化做得很好,眼睛水汪汪的,传达了非常动人的情感,仿佛能听懂人话一样。

《权力的游戏》中的巨龙,是这样的。跟它比起来,小白龙的差距并不太大。

有的网友表示,自己对这条小白龙爱不释手,直接给它配了个音——

于是一场配音大赛开始了。

现实场景,是给Sora最难的考题。

下面这个「一个男人在夏威夷热带水域上空定点跳伞,宠物金刚鹦鹉在旁边飞翔」的视频,Sora再次交出了让人印象深刻的答卷。

a man BASE jumping over tropical hawaii waters. His pet macaw flies alongside him

场景如此逼真,直接有人发问:「是真的视频还是AI做的?」

配上音后是这样的,就问会有多少人发现——这并不是真实的场景?

如果非要找茬,就是金刚鹦鹉的照明不太对,看起来像是单独做出来的动画,并不像自然条件下的光照。

定点跳伞的动作生成得不够准确,降落伞太小。

下面是一只玻璃乌龟,裂缝用金繕工艺修复,在日落时分走在黑色的沙滩上。

画面的一致性很完美,沙子的物理学特性也完全还原出来了。

不过美中不足的是:乌龟似乎只有三条腿??

也有人发现「华点」:把沙丘做出崎岖不平的样子,是为了让海龟爬过沙丘后不会留下痕迹吗?

相比之下,Midjourney生成的玻璃乌龟是这样的,别有一番风味。

精美的纸艺世界中的一艘船,海面还有海洋动物跃出。

in a beautifully rendered papercraft world, a steamboat travels across a vast ocean with wispy clouds in the sky. vast grassy hills lie in the distant background, and some sealife is visible near the papercraft ocean's surface

黑暗的霓虹灯雨林里,闪耀着奇幻的动植物。

a dark neon rainforest aglow with fantastical fauna and animals

不过对于这个视频,也有人挑刺说:「这是我见过的Sora最差的demo,它不知为什么就生成了矢量动画的风格。」

一只戴着眼镜的猫,出现在20世纪60年代的谍战电影中。

黄昏时分,一只巨大的半透明水母优雅地飘浮在荒芜的城市中,还是用35毫米胶片拍摄的超现实场景。

A surreal scene unfolds as a giant, translucent jellyfish floats gracefully through a deserted cityscape at dusk. The scene is shot on 35mm film

这是一个精心制作的立体模型:江户时代,木结构建筑前,一个孤独的武士慢慢穿过小镇。

A meticulously crafted diorama depicting a serene scene from Edo-period Japan. Traditional wooden architecture. A lone samurai, clad in intricate armor, walks slowly through the town

一只戴着护目镜的小胖哈巴狗,坐在一辆旧摩托车旁边的凳子上。

仔细看可以发现,狗肚子一呼一吸的样子,显得非常真实。

a small chubby Pug dog in goggles is sitting on a stool next to an old motorcycle

一只棕色边牧戴着太阳镜,滑着滑板。

a brown and white border collie stands on a skateboard, wearing sunglasses

可怕的事来了,有人在底下留言称,棕色边牧是自己的狗,这个视频是自己拍的。

而我们,竟有那么一刻恍惚了:他说的究竟是真是假?

总之,网友们迫不及待等待公测了。

还有人给Sora出了神考题——「一部手机正在直播进入黑洞的过程」。

网友猜测:虚幻引擎被用来生成部分数据集?

随着这些视频被放出,网友们心中的疑问也越来越强烈——

Sora模型究竟是用什么数据训练的?

不少网友也觉得,怎么Sora生成的画面,看起来有些似曾相识?仿佛就是直接用虚幻引擎(Unreal Engine)做出来的一样。

随后,越来越多人公认:Sora训练的数据集,应该就是用UE产生的。

其实,在Sora刚诞生时大佬就纷纷预测——Sora是由游戏引擎提供支持的。

Pytorch联合创始人Soumith Chintala就这样认为。

数据科学家和机器学习工程师Ralph Brooks也给出了自己的分析:

如果要创建大量不同角度的高清视频,就需要进行模拟。其中,有很多线索让我相信,UE5在一定程度上就是用来创建训练数据的。

比如这段广为人知的樱花漫步视频中,人物移动的方式跟UE5中非常相似。现实中的人走路是不会用恒定速度的。

英伟达高级科学家Jim Fan同样表示,「如果Sora接受过大量UE5合成数据的训练,我不会感到惊讶的!」

当然,它可能没有明确调用UE5,但非常有可能将UE5生成的文本、视频对作为合成数据,添加到训练集中。

早有预言帝猜中,Sora的推理管道是用的CLIP底座、文本转3D对象,和游戏引擎模拟。

果然,「人工训练数据耗尽」不会阻止LLM的发展,合成数据才是AI的未来!

「精简版」体验,就藏在技术报告里!

网友们看到这些一代比一代强的demo,已经心痒难耐了。

好消息是:虽然Sora还没有正式开放功能,但在技术报告里,已经可以小体验一把了!

报告地址:https://openai.com/research/video-generation-models-as-world-simulators

通过选择不同的关键词,比如人物、衣着、天气环境、地理位置等选项,就可以体验Sora生成的不同视频。

这样我们就可以看到——a穿着b样子的衣服,在c地点的d天气下,惬意地散步。

好莱坞大佬直言很害怕,影视行业真完蛋了?

这也难怪,好莱坞知名导演、制片人、演员Tyler Perry因为Sora,决定搁置自己亚特兰大工作室耗资8亿美元的扩建计划。

本来,Perry导演在过去四年里,一直计划斥资8亿美元扩建自己的工作室,为占地330英亩的土地增加12个摄影棚。

然而,在2月16日看过Sora做出的视频后,他决定撤销自己的8亿美元计划,因为他拍摄的大片中,可能并不需要找取景地,或者搭建实景了。

「以前,我们只是被告知AI可以做这些事,但是真的看到它做出来的场景,还是太令人震惊了!」

Perry导演表示,因为Sora给自己带来的冲击太过强烈,8亿美元扩建计划已被无限期推迟。

现在,拍电影时再也不需要亲自前往拍摄地点了。

不论是想要科罗拉多的雪地场景、月球上的场景,还是山中客厅中拍摄两个人的场景,都再也不要搭建真实布景,只要在办公室的电脑上,就能完成一切!

而这也就意味着,巨大的变化将波及行业的每一个角落,影响到演员、灯光、运输、音效和剪辑等所有从业者的饭碗。

现在,Perry导演已经在两部电影中的现场拍摄和后期制作中使用了AI,避免了耗费数小时给演员画老年妆。

Sora的出现彻底改变了游戏规则。

在以往,HBO的试播可能需要耗资1500万、2000万乃至3500万美元,而现在,这个成本低到不可想象。公司显然会选择成本更低的方案。

在不远的将来,很多工作岗位都会消失。

影视行业该建立怎样的安全防护措施,保住大家的饭碗?

Just yesterday, another brand-new masterpiece exploded, and two authors threw out brand-new pictures. By the way, they also showed a basic friendship. A panda and a toucan are best friends strolling in santorini Island at the blue moment, saying that this scene is exactly the same as the picture of two people walking to the office. The coherence of this video is simply amazing. The images of the panda and toucan are always consistent in each frame. Of course, there are still many flaws when you look closely. For example, the legs of the panda are sometimes intertwined. The screen looks more like a cartoon image than a realistic real world, but on the whole, the quality of this video is enough for us to imagine the future of the video. Some netizens immediately made a dubbing version, and a video has more flavor. No wonder the Hollywood director bluntly put aside his $100 million expansion plan of his studio after watching the produced video. More masterpieces are coming, and the second batch of videos released by the two authors are more realistic and bursting. How does it get better and better with each iteration? This video shows a diver discovering a hidden future sunken ship with cybernetic marine life and advanced alien technology. The diver's underwater landscape and the alien technology inside the sunken ship's shell are all very realistic. Of course, this scene is not perfect. Someone immediately found flaws. For example, the diver could swim without swinging his flippers and did not spit out bubbles. A Hollywood filmmaker spoke out that people's movements looked like. There is no soul in the past, but it is a bit like a zombie, but the quality of this second video is enough for a less critical audience. Some people say with satisfaction that it looks like a high-resolution version of Deep Sea Trek. In the past, this scene undoubtedly cost a lot of money, but now the difficult scenes of burning gold in Hollywood blockbusters can be replaced by videos to eliminate the film and television industry. It's not just talk. This little white dragon with pearly silver scales, ice-blue eyes and ivory dragon horns also makes netizens exclaim that his wife is so shocked. Its personification is very good, and its eyes are watery, conveying very touching emotions, as if it can understand people's words. The dragon in the game of power is like this. Compared with it, the gap between the little white dragon is not too big. Some netizens said that they loved this little white dragon and directly assigned a voice to it, so a dubbing contest began. The real scene is to give the most difficult questions. The following video of a man parachuting over hawaiian tropic waters and his pet macaw flying next to it was handed over again. The impressive answer sheet scene is so realistic that someone directly asks whether it is a real video or a sound, and then asks how many people will find that this is not a real scene. If you have to find fault, the lighting of the macaw is not right. It looks like an animation made alone, and the action of fixed-point skydiving is not accurate enough. The parachute is too small. Below is a glass turtle crack repaired by the golden repair process, walking on a black beach at sunset. The consistency is perfect, and the physical characteristics of the sand have been completely restored. However, the only fly in the ointment is that the turtle seems to have only three legs. It has also been found that Huadian made the sand dunes rugged so that the turtles would not leave any traces after climbing over the sand dunes. In contrast, the glass turtle produced has a unique flavor. In the paper art world, there are a ship on the sea surface and marine animals jumping out of the dark neon rain forest, and fantastic animals and plants are shining. However, some people criticize this video. This is the worst thing I've ever seen. For some reason, it generated the style of vector animation. A cat with glasses appeared in a spy movie in the 1900s. A huge translucent jellyfish floated gracefully in a deserted city at dusk. It was a surreal scene shot with millimeter film. This is an elaborate three-dimensional model. In front of a wooden building in the Edo era, a lonely warrior slowly passed through the town. A chubby pug with goggles sat on a stool next to an old motorcycle. If you look closely, you can find that the dog's stomach is very real. A brown border shepherd wears sunglasses and slides on a skateboard. Terrible things are coming. Someone left a message at the bottom saying that the brown border shepherd is his own dog. This video was taken by himself, but we were in a trance for a moment. In short, netizens can't wait for the public beta. Some people also gave a god question. A mobile phone is being broadcast live into a black hole. With these, netizens speculated that unreal engine was used to generate some data sets. The video was released, and the questions in netizens' hearts became more and more intense. Many netizens also felt that how to generate the picture looked familiar, as if it was made directly by unreal engine. Later, more and more people recognized that the training data set should be generated by using it. In fact, at the time of its birth, the co-founders predicted that it was supported by the game engine, so they thought that data scientists and machine learning engineers also gave their own points. If you want to create a large number of high-definition videos from different angles, you need to simulate them. There are many clues that make me believe that they are used to create training data to a certain extent. For example, the way people move in this well-known cherry blossom walking video is very similar to that in China. In reality, people don't walk at a constant speed. Senior scientists in NVIDIA also said that I wouldn't be surprised if I have received a lot of training on synthetic data. Of course, it may not be explicitly called, but it is very likely to be generated. As synthetic data, the text and video pairs are added to the training set. It has long been predicted that the reasoning pipeline is based on the base text-to-object and game engine simulation. As expected, the exhaustion of manual training data will not prevent the development of synthetic data. The future simplified version experience is hidden in the technical report. Netizens have been itching to see that these generations are stronger than the previous ones. The good news is that although there is no formal opening function, they can already experience it in the technical report. By choosing different report addresses, Keywords, such as people's clothes, weather, environment and geographical location, we can experience the different videos generated, so that we can see the clothes we are wearing and walk comfortably in the weather of the place. Hollywood bosses are frankly afraid that the film and television industry is really finished. It is no wonder that the famous Hollywood director, producer and actor decided to shelve the expansion plan of his Atlanta studio, which cost hundreds of millions of dollars. The director had planned to spend hundreds of millions of dollars to expand his studio and add a studio to the acre of land in the past four years. However, after watching the videos made on January, he decided to cancel his million-dollar plan because. 比特币今日价格行情网_okx交易所app_永续合约_比特币怎么买卖交易_虚拟币交易所平台
