Seedance 4K实测：电影感、特效与游戏画面效果对比

以下是视频口播的自动转写，可能有错字。

Hi, I'm a 2.0 just came out at 4K and I've already spent nearly10,000 testing it so you don't have to. And if you want to know what it actually changes, this video is for you.

I've tried everything from cinematic videos all the way to games and cgi, and the results are actually mind blowing. And spoiler alert, i don't think i can ever go back to 1080p.

So make sure to watch this on the biggest screen you've got turn the quality up to 4k and pause to catch the details. I'll also share all the prompts so you can easily recreate this even if you're a beginner.

Let's see if she dances in 4k is really worth it. Okay, look at this. The shot is insane. I mean, check out how texture the skin is.

Seriously, pause it and zoom in. This is absolutely mind-blowing. It's hyper realistic. If i saw this somewhere, i probably think it's from a movie.

Now, to get a cinematic shot like this, i use my professional prompt building skill. I just told cloud my entire idea when i generated a ready-to-use prompt.

I'll share the link to it down below. If you want to use it, i was really excited to test how she does 4k handles. Cinematics first, this was definitely supposed to be one of the most impressive parts of the whole update.

And you know what else? I noticed one huge thing when you generate in 4k, the detail and the cinematic frame mean, there's almost no slop like there was in 720p or 1080p because back then dealing with white charts with so many moving parts at once.

Was such a pain. Everything would either morph or just stay static and i wish we had 4k when we're making our film. Let me know how you would rate the shot out of 10 in the comments.

Now we're moving to the next cinematic and trust me, you are not ready for this one. All right. Now i feel like up until this point, i didn't even know what true ai realism look like to be honest.

It's loki scary. How good sea dances in 4k and what's even scarier is realizing that he has just getting started and this isn't even the ceiling, the detail in 4k jumped significantly compared to 720p or 1080p.

Look at the skin, the water, the backgrounds, every layer is cleaner now. Just think about how long this would take to render, and how much computing power you'd need to simulate all the water splashes, the close up eye texture, a giant octopus wrapping around a whale.

Now, let's see the last cinematic video in 4k. Okay，this is what i call an impossible shot. Generating an army of thousands of soldiers used to be such an impossible task for ai in 1080p。

the background characters would just melt into a blurry of pixel soup。but here even in this insane ultra wide 21 by 9 frame，the crowd holds up perfectly。

look at the ice cracking right between the soldiers，the chunks of snow falling down。Nothing is working. Every single pixel feels like it's exactly where it belongs.

By the way, quick takeaway for you guys. I generated all of this using purely text to video later on, we'll switch to image the video and i'll show you which image generation models, give you the best results with ctns 4k.

And also let me know in the comments, which cinematic videos you like the most. Now, let's see what happens when we mix C dance 4K with the real footage.

Now, for this video, I just recorded my laptop screen, dropped that footage straight into C dance, added a prompt, and the final result came out looking.

Insanely realistic, but it was just the beginning. What about pushing the tool further and trying a cyber effect on my hand?

And let's do horizontal this time. Okay, that looks pretty cool, but what about making it look like it's turning into a reptile hand?

Now，we can try to just completely erase my hand。I didn't even need a green screen to do any of this. The model handles all the masking automatically, right inside the shot.

Let's look at one last option and compare everything to the original clip. I've tested vfx in 1080p before, but it almost always changed small details and made the shot unusable.

But just look at how students 4k handles it. Now, it adds the effects perfectly without changing any of the details or the objects.

Okay, transforming real footage is great. But what about creating a full cartoon? Let's see how students 4k performs with animation.

And i cannot get over how crazy the quality is here. I mean, with the cinematic stuff, the focus was all on the detail here.

The image is so colorful. This video will look super high quality, even on a huge cinema screen and definitely wouldn't break down into pixels.

All right, let's do one more. Every clip i watch just makes me realize that 1080p is now in the past, like, it's just gonna look so blurry after this and keep in mind, i haven't even shown you the results for 4k games and cgi yet.

But before we do that, let's do one more animation style because they're just really fun. Okay, today's the day. I can feel it in my fur.

Wait. The lost chamber, it's real! Wow! Last one there hatches a rotten egg. Was it important? This is the exact style kids are obsessed with right now, but it usually takes a massive budget that only huge studios can afford.

I love how everything is dynamic, and you don't even have to manually prompt every scene or camera movements. It's honestly inspiring, because now anyone can just make a cartoon, whether it's a personal passion project or for a business.

In this insane pro quality. You don't have to stress about ai swap as much as before, burning through credits on endless rerolls or waste hours in editing.

4k just made the whole process so much easier. Like for this next cgi animation, i got it right on literally my second try.

Let's see what we got. Just watch how fast the camera rips past these gears and balloons that much motion and this many flying particles usually destroy our videos.

But look at this one, the color, the smoke, the reds, the haze. If you're a video nerd, here's the upgrade. See it ends outputs in 10-bit color.

Now, if you're not 8-bit video, gives you about 16 million colors. 10 bit gives you over a billion more colors mean smoother blends, so the smoke and reds melt together instead of stepping into those ugly bands you've seen break every cheap export.

No banding, it just looks expensive. To take advantage of that, just set the bit rate to high right here. Let me show you how this works for ads and brands。

Okay, honestly seeing quality like this makes me realize we're very close to seeing professional ai generated ads playing on giant billboards and times square or the sphere in vegas.

And here's why the biggest thing that changed for marketing videos is text. He doesn't 4k renders it way sharper now. So naturally, i wanted to see if i could completely break it.

So i fed it a bunch of inputs. Just to see how it handle them，let's see the results。All right, this ad is fire even here.

Students 4k handle the task perfectly. Now, when you watch any ai videos, your brain instantly spots, anything that looks unnatural like that fake perfect as skin.

That's the uncanny valley effect. We all know, but just look at the texture here, it completely breaks that effect and looks like it was actually filmed on a real camera.

Now, you might be wondering which image models actually work best here. I tested a few to see how they pair with c4k. The truth is that it works great with pretty much all of them, but you just need to choose them based on your specific tasks.

For characters, locations, and any keyframes, i use soul cinema. Because you can get 8 patches just for one credit, and it just gives you a much more cinematic shot by default.

If you need text, motion or storyboards, gpt image 2 is your best option. now, we're moving on to the most exciting part for me, gaming.

let's see how c-dance 4k handled this one. Okay，this one goes hard。It looks like an actual next gen game trailer。Look at the HUD，the health bars，the quest text，all of it stays crisp。

I made this using image to video。Notice how heavy and realistic the monster feels when it roars。Standard ai video always looks floaty because the models don't understand weight.

See, dance in 4k actually simulates true physics and its generations. When that massive creature moves, you can feel the scale.

This is a game changer for cinematic game trailers, because the action carries real physical weight. But the real challenge for any video model is high speed combat and complex special effects.

Let's switch to the second game clip to see how the model survives that kind of stress test。Okay, if you still think 1080p is enough for games and matix, this clip will completely change your mind.

Look at how fast the camera moves down the track while those giant hands try to grab the car. Older models could never handle depth on this level.

Students 4k actually understands 3d space and that's why 4k is an optional for shots like this anymore. It's a necessity.

Now let's look at the final game. Okay, now i have no doubts left that it's worth it. I mean, you just can't be quality like this.

And the best part is that you can apply this native 4k model to absolutely any visual style. You want, you can create hyper-realistic movies, sci-fi worlds, dark fantasy rpgs anime or anything else.

You can imagine there are literally no limits anymore. So if you want my honest opinion on whether she dance 4k is worth it.

It is a 100%. Yes, now you can try yourself in hixel too. I'll leave the link and all the prompts are used in the description.
