0:00Everything you're watching right now is
0:024K footage generated by Seedance 2.0
0:06using three completely different types
0:09of references. The character came from a
0:12single image, the camera movement came
0:14from a separate video, and the rhythm
0:16came from an audio file. Normally,
0:19combining all these together would
0:21require multiple tools, multiple
0:24generations, and a lot of manual work.
0:28But, for this project, everything was
0:30created inside BytePlus Seedance 2.0,
0:33the brand new 4K output just released.
0:37The visual quality could meet the
0:39professional standards for commercial
0:42work completely.
0:43>> So, let's go get it.

1:06>> For this test, I wanted to create a
1:08short cinematic commercial scene.
1:11Instead of starting directly with video
1:13generation,
1:15I opened BytePlus console.
1:17You can understand it as the official
1:19API portal for ByteDance's seed series
1:22models. One thing I like most is the
1:24extremely transparent pricing. It's
1:27fully usage-based billing, so there's no
1:29worry about getting overcharged. You can
1:32also experience the latest Seedance
1:34models as soon as they launch. Okay, so
1:36now find the Seedream 5 light model and
1:39click activate to enable it. Next, turn
1:43on this checkbox and click confirm
1:45activation and authorization. As you can
1:48see, the model has now been activated
1:50successfully. Inside Seedream, I
1:53generated the main visual for my
1:55project. In this case, I created a clean
1:59cinematic character image that would
2:01become the foundation of the entire
2:03video. Now, for video generation,
2:06there's no need to switch to another
2:08tool. Go back to the model activation
2:11section and find a SeaDance 2.0 [music]
2:13model. Just like before, click activate.
2:17If the checkbox is turned off, enable it
2:20and then click confirm activation and
2:23authorization.
2:24As you can see, this model has also been
2:27activated successfully. Now, I'll open
2:30SeaDance. Inside SeaDance 2.0 API, I
2:34opened almighty reference mode. This is
2:38the feature that makes the workflow much
2:40more practical. I can provide real
2:43references to guide the generation. For
2:46this example, I uploaded three different
2:49assets. First, the image generated in
2:52SeaDream. Second, a short video that
2:55contains the type of camera movement I
2:57want. And third, an audio track that
2:59contains the rhythm and atmosphere I
3:01want the scene to follow. Once [music]
3:04the files are uploaded, SeaDance 2.0 API
3:07automatically makes them available as
3:09references. Now comes the interesting
3:12part. Inside the prompt [music] box, I
3:15simply type the @ sign symbol.
3:17Immediately, all uploaded references
3:20become available.
3:22For example, I can tell it to use @ sign
3:24image one as the main visual reference,
3:28use @ sign video one as the camera
3:31movement reference, and use @ sign audio
3:34one as the rhythm [music] reference for
3:36the scene. That gives the model much
3:38more information than a normal
3:40prompt-only workflow. After setting up
3:43the references, I wrote a simple
3:45instruction and started the generation.
3:48A few moments later, SeaDance 2.0 API
3:52produced the first version of the shot.
3:55And this is where I started noticing the
3:57[music] biggest difference. Normally,
3:59when using traditional AI video
4:01workflows, if something is wrong, you
4:04often need to start over. You rewrite
4:06prompts, you generate again, you spend
4:09more credits, and you repeat the process
4:12until something [music] works. But
4:14because SeaDance 2.0 API already
4:17understands the image, the motion
4:19reference, and the audio reference, the
4:22results feel much more directed from the
4:25beginning. The camera movement follows
4:27[music] the reference more naturally,
4:29the visual style remains more
4:31consistent, and the overall scene feels
4:34much closer to the original idea. After
4:37generating the first shot, I wanted to
4:39make the sequence longer. Instead of
4:41creating a completely new scene, I used
4:44the extension workflow. This allowed me
4:47to continue the video while maintaining
4:50the same visual direction and overall
4:52consistency.
4:54>> [music]
4:54>> As you can see, the model did a great
4:56job analyzing the image, recognizing the
5:00character, and generating a very
5:02impressive cinematic scene. For creators
5:05who have full control and a repeatable
5:08node-based workflow, [music] you can run
5:11the exact same model directly inside
5:13ComfyUI through the API. Let me walk you
5:17through how I set this up. First, I
5:20opened the Byte Plus Model Arc console,
5:23where SeaDance 2.0 is fully available.
5:26Inside the console, [music] under
5:28Configurer, I created a new API key.
5:32This is the credential that lets any
5:35external tool [music] talk to the model.
5:37Then, I went to Model Activation, opened
5:40the Media tab, and made sure Dream and
5:43our SeaDance 2.0 was activated and ready
5:46to use. Now, I have everything needed to
5:49connect an external tool to the model.
5:52Inside ComfyUI, I opened the nodes
5:55manager, searched [music] for the C
5:56Dance integration, and installed it.
5:59After a quick restart, the new nodes
6:02were ready. Then, I added the C Dance
6:042.0 reference to video node. This is
6:08where the workflow becomes powerful. The
6:10node has separate [music] inputs for
6:13image, video, and audio references,
6:16exactly like the almighty reference
6:18system, plus controls for resolution,
6:21aspect ratio, duration, and audio
6:24generation. I connected my references,
6:28wrote a prompt describing the scene, and
6:31ran the workflow. A few moments later, C
6:34Dance generated the video directly
6:37inside ComfyUI, no browser, no manual
6:41clicking, [music] just a repeatable node
6:44graph. Because it's node-based, the
6:47workflow can be saved, reused, and
6:50automated. Why would anyone use this
6:53tool?
6:54Let's take a quick look at what I did in
6:56this video.
6:58First of all, I activated the API. I
7:01started with a visual in C Dream. I
7:04moved into C Dance 2.0 API. I uploaded
7:08image, video, and audio references. I
7:11connected [music] them using the @ sign
7:13reference system. I generated the video.
7:16I extended the result, [music] and I
7:18ended up with a much more controlled
7:21final output than I would normally get
7:23from a prompt-only [music] workflow.
7:26Compared to traditional methods, this
7:28process isn't just faster, it's actually
7:31more stable and much [music] easier to
7:33repeat for future projects, and reliable
7:36enough to build a business on. With C
7:38Dance 2.0 API, I can build the image,
7:42references, motion direction, and final
7:45video workflow run the much more
7:48controllable process. For creators, this
7:52means cutting production time by 80% and
7:55taking on more projects. It supports
7:58batch [music] generation, so you can
8:00create hundreds of videos at once
8:03without tedious one-by-one clicking. It
8:06guarantees zero queuing with instant
8:09rendering even for urgent commercial
8:11projects, so you never have to wait in
8:14global queues. It integrates seamlessly
8:17with N8 and Animate AI, so you can build
8:20fully automatic trigger-based pipelines.
8:23[music]
8:24It offers pay-as-you-go pricing, making
8:27it far more cost-effective than fixed
8:29subscriptions for high-volume projects.
8:33Before SeeDance 2.0 API, a 50-video
8:36client project took me five full work
8:39days to complete.
8:41>> [music]
8:41>> Now, I finished the exact same project
8:44in eight hours. That's 15 times faster
8:48delivery. For commercial projects,
8:50product ads, storytelling videos, and
8:53social media content, this becomes
8:56extremely useful because continuity is
8:59often one of the biggest challenges in
9:01AI video generation.
9:04If you'd like to use the exact workflow
9:06shown in this video, [music]
9:08I've included my director-level workflow
9:10blueprints in the description and pinned
9:13comment. You'll also [music] find the
9:15official SeeDance 2.0 API purchase link
9:19there.
9:20You can download the blueprint,
9:21>> [music]
9:22>> activate your SeeDance 2.0 API resource
9:25package, create video workflows, client
9:28projects, content pipelines, or
9:31AI-powered [music]
9:32video products. Thanks for watching, and
9:35I'll see you the next video.
