Video to Video, Guide:Replace People, Objects and Scenes in Your Clip

Bring a clip you already have and change what is inside it. Replace a person with another character, swap a product, change the setting, or keep the shot running past where it stopped, with Track progress in your workspace and no watermark on the download. New generation requires an account and a confirmed quote.

Real output

Same shot, different product

One clip went in as the source and one still went in as the replacement reference. A single sentence of instruction produced the result: same camera, same lighting, new object.

Prompt

Change the perfume in the video gift box to the face cream from the image.

Source clip, plus the reference still that replaces the product.

Result

Seedance output, watermark-free.

Use cases

What an existing clip becomes

Video to video is the mode for footage that is almost right: the shot works, but something inside it has to change.

Replace a person or an object in finished footage

Keep the set, the lighting and the camera move, and swap who or what is in the frame: another character from a still, the SKU that actually shipped, a different car. One clip can then cover a whole catalogue or a whole cast.

Restyle without a reshoot

Push the same take into a different look, season, palette, or era while the blocking and the timing stay exactly where they were.

Extend a shot that ended too early

Continue a clip past its last frame when the edit needs one more beat and the original footage is long gone.

Localized fixes

Change one region of the frame, such as a label, a sign, or a garment, and leave everything around it untouched.

How it works

How video to video works here

Attach the clip and the composer switches itself. Adding a still alongside it turns the pair into a reference group.

01
Attach the source clip
Drop the clip in first. Stills added next join it as reference material rather than replacing it, and on the Seedance models more clips can follow: up to three on Seedance 2.0 and ten on Seedance 2.5.
02
Write the change, not the scene
Say what should be different. Replace the perfume in the gift box with the cream from the image is the shape that works; a full scene description fights the source.
03
Generate and compare
The result lands next to the original in your asset library, watermark-free, so you can judge the swap frame by frame.

Jobs people arrive with

Five edits people bring a clip here for

These are the jobs the clip arrives with, named the way people ask for them. Each has a direct answer, the steps in this composer, the instruction verbatim and the model that fits, so you can paste the prompt and run it on your own footage.

Replace a person in a video with another character

Yes. Attach the clip, add one still of the character who should appear instead, and name the swap in a sentence. The model keeps the movement, timing, camera and lighting of the original and re-renders the person. with purchased credits this runs on Seedance 2.0 Mini at up to 720p; Seedance 2.5, on a paid plan or a credit pack, does it as a localized edit that leaves the rest of the frame untouched. One limit to know before you start: the Seedance models refuse some footage of real people and photorealistic faces under ByteDance’s content rules, so a stylized or clearly fictional replacement is the reliable choice, and a refused job is not charged.

How to do it

Attach the source clip, 2 to 15 seconds long; the composer switches to video to video.
Add one clean still of the replacement character as a reference.
Write the swap as one instruction: who goes out, who comes in from the image, and that everything else stays.
Generate, compare against the original in your library, and reuse the same still for every further shot.

Prompt

Replace the man in the video with the character from the image. Keep his movements, timing, framing, camera motion and lighting exactly as they are; change nothing else in the scene.

Settings

Model: Seedance 2.0 Mini with purchased credits (720p) · Seedance 2.5 for a localized edit on a paid plan or credit pack
Inputs: one source clip plus one reference still of the character
Output length follows the model: up to 15 seconds on Seedance 2.0, up to 30 on Seedance 2.5

Prompt recipe: no clip attached, paste it and run it.

Swap an object in a video, such as a product, a car or a prop

Yes, and it is the job this entry does best, because what you keep is the shot and what you change is small. Give the model one still of the replacement, name the object to remove and the image it comes from, and leave the rest of the sentence empty. The perfume-to-face-cream pair in the demo above was made exactly this way on Seedance 2.0: one clip, one still, one sentence.

How to do it

Attach the clip that has the object in it.
Add a still of the replacement, shot as cleanly as possible: one object, plain background.
Name the object to replace and the image that replaces it; do not describe the scene.
Run it; if the object drifts, shorten the source clip or crop the still tighter.

Prompt

Replace the glass on the table with the can from the image. Keep the hand, the table, the lighting and the camera movement unchanged.

Settings

Model: Seedance 2.0 or 2.0 Mini with purchased credits · Seedance 2.5 for a localized edit
Inputs: one source clip plus one reference still
Real pair: the demo at the top of the page and the first worked example below

Change the background or setting behind the action

Yes, without a green screen. Describe the new place and say that the people, their movement and the camera stay. The model re-renders the environment around the action: a kitchen becomes a studio, a car park becomes a coastline, noon becomes night. On Seedance 2.5 this is a localized edit that keeps the subject stable; on the Seedance 2.0 family, including Mini with purchased credits, the scene is re-rendered from the clip, which suits a full restyle more than a one-object fix.

How to do it

Attach the clip; a still of the new setting is optional but keeps the look consistent across shots.
State what stays: the people, the action, the framing and the camera path.
Describe the new setting and the light that comes with it in one or two clauses.
Generate; for a series, reuse the same setting still so every shot lands in the same place.

Prompt

Keep the two people, their movements and the camera path exactly as in the source. Change the setting to a rooftop at dusk with city lights behind them; match the new light on their faces and clothes.

Settings

Model: Seedance 2.5 for a localized background edit · Seedance 2.0 / Mini for a full restyle
Inputs: one source clip, optionally one still of the new setting
Resolution: 720p with purchased credits and Lite, 1080p on Pro and Premium for Seedance

Prompt recipe: no clip attached, paste it and run it.

Add people or objects to footage you already have

Yes. The instruction names what appears, where, and how it behaves, and the rest of the shot is left alone: twenty students in an empty classroom, a car in an empty driveway, a product on a bare table. A reference still of the thing to add makes it specific; without one the model invents it from the words. Crowds and many small additions are harder than one clear object, so start with one.

How to do it

Attach the clip with the empty space in it.
Optionally add a still of what should appear.
Say what to add, where it goes and what it does, then say the rest stays unchanged.
Generate and check the edges where new and old meet; a shorter clip gives a cleaner join.

Prompt

Add a red sports car parked in the empty driveway on the left, matching the afternoon light and shadows. Keep the house, the camera movement and everything else exactly as in the source.

Settings

Model: Seedance 2.0 Mini with purchased credits · Seedance 2.5 for a cleaner localized insert
Inputs: one source clip, optionally one reference still of the added object
Tip: one addition per instruction; stack further additions as separate runs on the result

Prompt recipe: no clip attached, paste it and run it.

Change clothes, hair or makeup and keep the person

Yes. This is the smallest kind of replacement: the person, the performance and the camera stay, and one attribute changes. Name the attribute and the new value, and say the face and the movement stay. A reference still of the garment or hairstyle helps the model match a specific look. The same real-people caveat applies: footage with photorealistic faces can be refused, and a refusal is not charged.

How to do it

Attach the clip of the person.
Add a still of the garment, hairstyle or look if you need an exact match.
Write one change: “change only the jacket to…”, “change only the hairstyle to…”.
Generate; keep the source short so the change holds across every frame.

Prompt

Keep my face, expressions, movements and the room exactly as in the source. Change only my hairstyle to soft natural curls, shoulder length.

Settings

Model: Seedance 2.0 Mini with purchased credits · Seedance 2.5 for a localized edit
Inputs: one source clip, optionally one reference still
Output length follows the model, not the source

Prompt recipe: no clip attached, paste it and run it.

What you can generate

What video to video can generate here

Only the models that accept a reference clip appear in this table, and every value is read from the registry the composer enforces. The inputs column separates the two ways a clip can be used: as a reference that the scene is re-rendered from, and, on Seedance 2.5 alone, as the source of a dedicated edit or extend job.

No model quotes are currently available. Please try again later.

Of the entry models only Seedance 2.0 Mini accepts a reference clip, so a video-to-video test with purchased credits runs on Mini at up to 720p. Seedance 2.5, with the dedicated edit and extend modes, needs a paid plan or a credit pack, as do Kling O3, Kling 3.0 and 2.6 Motion Control, MiniMax H3 and Wan 3.0.
Source limits differ by family. Seedance 2.0, Fast and Mini take MP4 or MOV clips up to 50 MB and 2 to 15 seconds long, up to three at once; Kling O3 takes one clip of 3 to 10 seconds up to 200 MB; Kling 3.0 and 2.6 Motion Control follow a reference of 3 to 30 seconds and need a still of the character as well.
Output length follows the model, not the source. A 5-second source can become a 15-second Seedance 2.0 clip, and a 1080p source does not lift a 720p plan cap.
Each task uses the current generator quote for its model, duration, resolution and references. Identical settings cost the same credits on every plan; subscriptions do not reduce the task credit charge.

Resolution cap by plan

Available models, resolutions and reference formats are shown in the generator. Credit-mode concurrency is 1 for Lite, 4 for Pro and 8 for Premium. A model guide is not a guarantee that every discussed model is currently enabled.

Worked examples

Three video-to-video jobs, end to end

The first example is the real pair from the demo above with its unedited instruction. The other two are prompt recipes for the two remaining jobs this entry does, a restyle and an extension, written against Seedance 2.5’s modes so you can run them on a clip of your own.

Perfume out, face cream in

Before

A finished five-second gift-box clip with a perfume bottle inside it, plus one still of the face cream that should be there instead. Two attachments, one sentence.

After

The same camera move, set and lighting with the cream in the box. Nothing else in the frame was mentioned, so nothing else moved. This is the pair shown in the demo section above, and the shape of the instruction is the lesson: name the object to replace and the image it comes from.

Prompt

Change the perfume in the video gift box to the face cream from the image.

Settings

Model: Seedance 2.0
Inputs: one 5-second source clip plus one reference still
Entry: video to video, inferred from the attached clip

Restyle a midday interior to dusk

Before

A handheld eight-second walkthrough of a furnished living room shot at noon: flat light, correct blocking, the kind of take you would keep if only the mood were different.

After

The same walk with the same timing, now at dusk: table lamps on, cool blue window light, longer shadows, with the furniture, layout and materials unchanged because the instruction told the model to leave them alone.

Prompt

Keep the camera path, framing and timing of the source clip exactly. Change the time of day to dusk: warm table lamps switched on, cool blue light through the windows, soft long shadows. Furniture, layout and materials stay the same.

Settings

Model: Seedance 2.5, paid plan or credit pack required
Inputs: one source clip, no stills
Duration: 8 seconds to match the source · Resolution: 720p on Lite, 1080p on Pro and Premium
Mode: edit, inferred from the instruction

Prompt recipe: no clip attached, paste it and run it.

Extend a shot that ended too early

Before

A six-second clip of a cyclist crossing a bridge at golden hour that cuts just as she reaches the far side, one beat before the edit needs it to.

After

The shot continues: she rides off the bridge into a narrow town street while the camera holds its pan at the same speed, and the light and grain match the original so the join does not read as a cut.

Prompt

Extend the video by 5 seconds. The cyclist rides off the far end of the bridge into a narrow town street, the camera keeps panning at the same speed, same golden-hour light and film grain, no cuts.

Settings

Model: Seedance 2.5, the only model with a dedicated extend mode
Inputs: the 6-second clip as the source
Duration: the seconds to add, 4 to 30; the result is the new segment only, to place after the original
Mode: extend, detected from the word “extend” in the instruction

Prompt recipe: no clip attached, paste it and run it.

Questions

Video to video questions

What can I send in?: A source clip plus stills as references. Seedance 2.0, Fast and Mini take MP4 or MOV up to 50 MB and 2 to 15 seconds long, and up to three clips per generation; Seedance 2.5 accepts up to ten reference clips alongside up to 30 reference images; Kling O3 takes one clip of 3 to 10 seconds up to 200 MB. Short sources read best, because the longer the clip runs the more the model has to hold consistent. Only upload footage you have the right to use.
Can I replace a person in my video with another character?: Yes. Attach the clip and one still of the character who should appear instead, then write the swap as one sentence that names who goes out, who comes in from the image and that everything else stays. The movement, timing, camera and lighting are kept from the original. Free credits run this on Seedance 2.0 Mini at up to 720p; Seedance 2.5 does it as a localized edit on a paid plan or a credit pack. The Seedance models refuse some footage of real people and photorealistic faces under ByteDance’s content rules, so a stylized or clearly fictional replacement is the reliable choice, and a refused generation is not charged. The task section above has the exact prompt.
Can I swap one object for another, such as a car or a product?: Yes, and it is the most reliable job on this page. One still of the replacement object, one sentence naming what to remove and which image it comes from, and nothing else in the sentence: the demo pair at the top of the page replaced a perfume bottle with a face cream on Seedance 2.0 that way. The camera, set and lighting stay because you never asked them to move. Keep the source clip short and the reference still clean for the most stable result.
Can I change the background of a video without a green screen?: Yes. Say that the people, their movement and the camera path stay, then describe the new setting and its light. Seedance 2.5 treats this as a localized edit and keeps the subject stable while the environment is re-rendered; Seedance 2.0 and Mini re-render the whole scene from the clip, which suits a full restyle. A still of the new setting is optional and keeps a series of shots in the same place.
Can I add people or objects to footage I already have?: Yes. Name what appears, where it goes and what it does, add a reference still if it has to be a specific thing, and say the rest of the shot stays unchanged. One clear addition per run works far better than a crowd of small ones; stack further additions as separate runs on the result. Seedance 2.0 Mini handles this with purchased credits, and Seedance 2.5 gives a cleaner localized insert on a paid plan or a credit pack.
Is it free, is there a watermark, and do I need a card?: Eligible new verified accounts may claim up to 5 welcome credits for 7 days after human verification, while the promotion budget is available. This can cover a low-cost image, not a guaranteed free video. New video generation requires sufficient purchased credits or eligible bounded unlimited capacity.
Which model handles editing and extending, and do I pick a mode?: Seedance 2.5 is the one built for it: up to 30 seconds, up to 30 reference images and ten reference clips, and dedicated edit and extend modes that change one region or continue past the last frame instead of regenerating the whole shot. You never pick the mode; the instruction decides. Asking for a replacement runs an edit and asking for what happens next runs an extension. Seedance 2.0, Fast and Mini, Kling O3, MiniMax H3 and Wan 3.0 accept a reference clip and re-render the scene from it, which suits restyles and product swaps, and Kling 3.0 and 2.6 Motion Control are the specialists for transferring a performance from a clip onto a still.
How long and how sharp can the result be?: Available models, resolutions and reference formats are shown in the generator. Credit-mode concurrency is 1 for Lite, 4 for Pro and 8 for Premium. A model guide is not a guarantee that every discussed model is currently enabled.
What does a video-to-video generation cost?: Each task uses the current generator quote for its model, duration, resolution and references. Identical settings cost the same credits on every plan; subscriptions do not reduce the task credit charge.
Is openaiimage.com the official ByteDance site for Seedance?: No. Open AI Image at openaiimage.com is an independent platform, not a ByteDance property. It runs the official Seedance model API alongside Kling, Veo, MiniMax and Wan, so the Seedance output you get here is produced by the model ByteDance publishes, but the workspace, the credits and the plans are ours. Model names belong to their respective owners, and nothing on this site is endorsed by them.
Can I use edited footage commercially?: Paid plans and credit packs support commercial workflows, subject to service terms, supplier restrictions and rights to your input media.
How long does it take?: A few minutes, towards the upper end of what a text prompt takes on the same model, because the model reads the source before it renders. The progress bar is paced off per-model estimates, roughly four minutes for Seedance 2.0 and about a minute and a half for Seedance 2.0 Fast, and it stretches for longer outputs, 1080p and busy periods. The workspace shows an “about N min left” estimate while it works, and free credits and Lite run one job at a time where Pro runs four and Premium eight.
How do I keep the product or character consistent through the edit?: Give the model one clean reference of the thing that must stay fixed, name it in the instruction, and change nothing else in the sentence: “replace the perfume with the cream from the image” keeps the camera, set and lighting because you never asked for them to move. Keep the source short, avoid heavy motion blur, and for a run of variants reuse the same reference still on every generation. Seedance 2.5 takes up to 30 reference images, so a whole product line can travel with the clip.
Video to video here, or Runway Aleph or Kling, for a product swap?: All three can restyle a clip; the difference is how the change is scoped. Seedance 2.5’s localized edit changes the region you name and leaves the rest of the frame alone, and it does so with the same references you use everywhere else on this site, up to 30 images and ten clips. Kling O3 sits in the same picker, so you can run the identical source and instruction through both and compare frame by frame without leaving the workspace. Runway Aleph is not offered here, and we publish no benchmark against it; judge it on its own output.

Choosing an entry

Video, image or text: which entry fits

The three scene pages share one composer. What you attach decides the entry, and the model you pick decides the ceiling.

A clip is the right entry when the footage is almost right and only one thing in it has to change. When the shot does not exist at all, start from text to video and describe it. When you have a packshot, a poster or a portrait but no footage, start from image to video, where the still becomes the first frame and the prompt supplies the motion.

Within this entry the model matters more than anywhere else. Seedance 2.5 is the only model with dedicated edit and extend modes, and the only one that takes ten reference clips and 30 reference images, so localized fixes and extensions belong to it. Seedance 2.0 and its Fast and Mini tiers re-render a scene from a reference clip at a lower cost, which is enough for a restyle or a product swap. When a performance from one clip has to land on a still of someone else, use motion control: Kling 2.6 Motion Control does it at the lower credit rate, and Kling 3.0 Motion Control is the newer generation.

When the clip is right but ends too early, you do not need to change anything inside it: the AI video extender continues it from the last frame for 4 to 30 seconds on Seedance 2.5, with a worked example, the exact instruction and the cost per plan.

Keep going
