Hybrid filmmakingSeedance 2.0True 4KShoot the blocking. Render the film.
Hybrid filmmaking keeps what only you can do on set: the camera move, the timing, the performance. Film it as a rough greybox with stand-ins, add pictures of your cast, costumes and locations, and Seedance 2.0 renders the finished shot in 4K.

What hybrid filmmaking means
Traditional production spends most of its budget on things the audience never thinks about: building sets, travelling to locations, lighting, wardrobe, crowd, VFX. Pure text-to-video skips all of that, but it also takes away the director: the camera does what the model guesses, not what you planned.
Hybrid filmmaking splits the job. You make the creative decisions with a real camera (or a 3D previz): where the lens sits, how it moves, who crosses frame and when. The model does the expensive rendering: the faces of your cast, their costumes, the location, the light and the grade. Because Seedance 2.0 follows the greybox clip frame by frame, the shot keeps your coverage and your edit points, so it cuts together like footage.
Direction
Camera move, framing, lens height, blocking, performance timing, the rhythm of the cut.
Production value
Cast likeness, wardrobe, locations you can't afford to reach, weather, time of day, lighting and grade.
Days, not minutes
A greybox day with two stand-ins and a phone replaces a location, a crew and a set build for many shots.
The workflow
- Shoot the greyboxStand-ins in plain grey or neutral clothes, simple set pieces, your real camera move. Give each stand-in a different coloured band so they are easy to tell apart. 24 fps, locked exposure, 2 to 15 seconds per shot. A grey-shaded Blender or Unreal previz works too.
- Collect referencesCharacter art for each role (stylised or illustrated: ByteDance refuses photo-realistic faces as references), the location, props, a look reference, and up to three costume pictures.
- Write the shotDescribe the action, light, lens and look, or let the AI prompt helper write it from a few notes. The studio tells the model which picture is which.
- Draft at 720pAbout 102 credits for a 5-second shot. Check likeness, blocking and look. Try a few takes; each take keeps its seed.
- Final at 4KOne click turns the take you like into a 4K final with the same seed and settings. About 475 credits for 5 seconds.
- Edit and gradeDownload the MP4s and cut them in Resolve, Premiere or Avid like any other footage.
Seedance 2.0 or 2.5?
The studio offers both. Pick per shot; keep one model for every shot in a scene so the cuts match.
| Seedance 2.0 | Seedance 2.5 | |
|---|---|---|
| Best for | Big-screen deliverables, festivals, 4K masters | Web, social and pitch films where realism matters most |
| Look | Cinematic, very faithful to the greybox | Newer model: more realistic faces, skin and motion |
| Top resolution in the studio | True 4K | 720p |
| 5 s shot (from a 5 s greybox) | ~102 credits at 720p · ~475 at 4K | ~68 credits at 480p · ~152 at 720p |
| Draft → final | 720p draft → 4K final, same seed | 480p draft → 720p final, same seed |
How to shoot a greybox
A greybox is a rehearsal you film. It doesn't need to look good; it needs to be precise. Everything the model can't guess (where the camera goes, who moves where, when) has to be in the clip. Everything it can paint (faces, costumes, set dressing, light quality) can stay rough.
Write the shot first
- One shot = one action and one camera move, 4–15 s.
- Fill a line of the shot sheet: scene, shot, lens, move, action, length.
- Split dialogue and big moments into coverage, as you would on set.
Match the silhouettes
- Plain grey or neutral clothes, no logos.
- Match each character's height, build and outline (a cap for big hair, a sheet for a long coat).
- A different coloured armband per character; use the same names in the prompt and on the reference pictures.
Real sizes, rough shapes
- Boxes and stands for furniture at true size and position.
- Tape marks for doors, windows, edges of the set.
- Keep screens, text and crew out of frame.
Move it like the final
- Frame in the final shape (16:9, 2.39:1 → 21:9, 9:16…).
- Lock focus, exposure and white balance; 24 fps, shutter around 1/50.
- Smooth moves: gimbal, slider or a steady hand. Avoid whip pans and heavy blur.
Show where the key is
- One lamp from the side the final key light will come from; the model follows shadow direction.
- Even, flat light is fine; don't blow out faces or windows.
Clean and short
- Trim handles off: the clip is the shot.
- MP4 (H.264), 1080p or smaller, 2–15 s.
- Name it like the slate:
S03_3B_T1.mp4.
Best practices for a planned, consistent shot
| Do | Why |
|---|---|
| Use stylised or illustrated character art (front and three-quarter), and describe faces in words | Photo-realistic faces are refused by ByteDance's filter; clear character art plus a consistent written description keeps characters steady between shots. |
| Turn the stand-in's face the way the character's face should be | Head direction and eyelines come from the greybox, not the photo. |
| Shoot costumes as flat-lays or on a mannequin, whole garment visible | Cut-off or folded clothes get invented; full garments get matched. |
| Photograph locations wide, at the same time of day as the scene | A wide still sets geography and light; close-ups of textures don't. |
| Describe light, lens and look in the prompt, not the action | The action is already in the greybox; words are best spent on what the camera can't show. |
| Draft at 720p, change one thing at a time, then lock the seed | Same seed + same inputs = a 4K final that matches the draft you approved. |
| Reuse the same references and wording across every shot of a scene | Consistency across cuts comes from identical inputs. |
| Keep 9 pictures or fewer per shot, only the characters in it | Seedance takes 9 references; extra faces confuse who is who. |

Or load any amount from $25 in the studio; it gets the bonus of the biggest pack it reaches. Credits are metered by the second: you only use credits for what you render, and failed or blocked shots are refunded. A shot is billed on its length plus the greybox clip's length. Rough guide for finished screen time with three 720p drafts and one 4K final per shot: about 156 credits per second.
What it's good at, and the limits
- Great for short films, feature films and music videos, plus ads, pitch trailers, proof-of-concept scenes, previz upgrades, pick-ups and location swaps. Very few people are making AI feature films yet: less competition, and room to be a pioneer.
- Each shot is 4 to 15 seconds. Build scenes shot by shot.
- 9 reference pictures per shot. Keep each shot to the characters in it.
- Dialogue lip-sync is not frame-accurate yet. Plan dialogue on over-the-shoulders and wides, or shoot those close-ups for real.
- Only upload people, footage and designs you have the rights to.
Questions
What is a greybox shot?
A rough version of your shot filmed with stand-ins in plain clothes on a simple set (or a grey-shaded 3D previz). It carries the camera move, framing, timing and performance. Seedance 2.0 keeps all of that and paints in your cast, costumes, location and lighting.
How long can a shot be?
Seedance 2.0 makes 4 to 15 seconds per shot, and the greybox clip can be up to 15 seconds. Longer scenes are cut into shots, the same way you would cover them on set.
How many reference pictures can I add?
Up to 9 per shot: cast, locations, props or a look reference, plus up to 3 costume pictures, 9 in total. That is the model's limit. For a big ensemble, split the scene into shots with the characters that are in each one.
Why draft first?
A 5-second 720p draft costs about a fifth of a 4K final. Check the blocking, likeness and look in the draft, then make the 4K final with the same seed and settings so it comes out close to the draft you approved.
How is a shot billed?
Per second of the finished shot plus per second of the greybox clip you send, at the resolution you pick. The studio shows the exact credits before you press the button. Failed or blocked shots are refunded automatically.
Can I use photos of real actors?
Not as face references right now: ByteDance's filter refuses pictures that look like real people, even AI-generated ones. Use stylised or illustrated character art, costume and location pictures, and describe the person in words. A refused shot costs nothing.
Should I use Seedance 2.0 or 2.5?
Seedance 2.0 for 4K masters and the lowest cost per second. Seedance 2.5 is ByteDance's newer model with more realistic faces and motion, up to 720p in the studio, at about 45% more per second. Keep one model per scene so shots cut together.
Do film credits expire?
No. Credits never expire. Each pack opens the film studio, Seedance 2.0 and every image model for 12 months from your latest pack, with no monthly plan needed.
Who owns the output?
You do, for commercial use, as long as you had the rights to the footage and pictures you uploaded. See our terms.
