AI Video Face Swap
Carry one face through a clip so a catalogue stays one performer at FlowBioLinks. Priced by length and resolution, with a suitability guide.
One face, through the whole clip
Clips gathered from different rooms and different months should still star the same woman. The video face swap at FlowBioLinks carries your character’s face through existing footage, priced by clip length and resolution on the video_face_swap model and shown before you confirm. The still rules apply with interest: one source portrait, steady footage, and judgement at the joins.
What the swap asks of footage
Motion gives a swap nowhere to hide. The face must be found, tracked and re-lit in every frame, so the footage that swaps well is footage that behaves: a camera that holds still or drifts slowly, one light that stays lit, a face that stays clear of hands, hair and props. Short clips hold best. A three-second turn re-cast cleanly is worth more to a catalogue than a thirty-second scene that breaks at every profile. Your own footage, or footage you hold documented consent to transform — the rule does not soften because the clip is short.
The working routine
Fix the source portrait
The same frontal, evenly lit portrait used for still swaps. One source across stills and video is what keeps her identical in both.
Choose steady footage
Short, single-light, face clear. Judge the source clip before it costs anything: if the face is lost in the original, it is lost in the swap.
Judge the joins
Turns, crossings, changes of light — watch the whole clip at full size, at the joins, before anything ships.
Where it is used
One performer, many sources
Clips made in different rooms and different months, re-cast so the catalogue reads as one woman throughout.
Scenes set onto your character
A scenario briefed once and shot plainly becomes your character’s scene once the transfer is done.
The movement was right
When the performance holds and only the face is wrong, repair the cheaper half of the problem.
Clip suitability
| Trait | Holds well | Strains the swap |
|---|---|---|
| Face angle | Frontal to three-quarter | Long passages in profile |
| Camera | Still, or moving slowly | Whip pans, heavy shake |
| Light | One light, held through the clip | Strobe, hard cuts between setups |
| Obstruction | The face clear | Hair, hands or props crossing it |
Where swaps go astray
| Symptom | Cause | Correction |
|---|---|---|
| The face slips at a turn | Profile passages starve the tracker | Cut the clip at the turn; swap the frontal passage |
| Flicker across frames | The light changes mid-clip | Use single-light footage; grade after the swap |
| She ages or softens | The source portrait was a still swap | Return to the original portrait, always |
Whose face, and whose footage?
Your own face, or a fictional character’s, set onto footage you own or hold documented consent to transform. Real third parties without consent are prohibited.
How is it priced?
By clip length and resolution, calculated per job and shown before you confirm. Failed jobs refund automatically.
Why does a swap break mid-clip?
At a profile turn, a change of light, or something crossing the face. Short, steady clips hold best; judge the joins before anything ships.
Should the source match my stills?
Yes — the same file. One source across stills and video is what keeps a character identical in both.
Are uploads public?
No. Sources, clips and results rest private in your account.
