The source clip supplies motion and layout; the model supplies new surface. Restyle a live-action take into illustration, swap what a character is wearing, change the weather in a shot — the camera move and the timing survive because they were never regenerated.
It is harder than the image equivalent for one reason: every frame has to change the same way. Applying an image edit frame by frame produces a clip that boils, because each frame was solved independently. Video models that do this well are solving the sequence, not the pictures.
Because the structure is fixed, prompts are narrow by nature. "Make it snow" works; "make it a different shot" does not, and asking for a change that contradicts the source motion usually produces the source motion with artefacts on top.
In practice
- The edit is bounded by the source: no new camera moves, no new blocking.
- Shorter sources hold up better — drift is cumulative over frames as well as over extensions.
- Source compression artefacts get amplified; feed the highest-quality file you have.

The mistake to avoid
Judging a video-to-video result on a single frame. The failure mode is temporal — a still can look perfect while the sequence flickers.

Image-to-image
Image-to-image takes a picture as its primary input and returns a changed picture — restyled, corrected or varied — instead of inventing one from nothing.
Denoising strength
Denoising strength meaning: how much of your input picture is replaced before regen. Low keeps it close; high keeps only the rough shape.
Temporal consistency
Temporal consistency means staying stable over time; in video, each frame agrees with the one before, so nothing flickers, shimmers or drifts as it plays.
Segmentation
Segmentation labels which pixels in each frame belong to a chosen object, producing a mask that other tools then act on.
Text-to-video
Text-to-video is generation from a written prompt alone — you describe a shot, the model invents every frame of it, and no image or footage goes in.
