AI Video Face Swap
Her face carried through moving frames at 51CgPro: video_face_swap at 31 credits a job, judged in three viewings, consented sources only.
Fictional faces, your own face, or documented consent only — in video as in stills.
Her face, held through the whole clip
Video face swap at 51CgPro transfers her face across a whole clip rather than a single frame. The video_face_swap model runs at 31 credits a job, quoted before you confirm. It suits the catalogue problem motion creates: a performance with the right movement and the wrong face. Give it her face from her proven stills and the performance becomes hers — provided the clip is judged the way clips here are always judged, in three viewings, before finishing money follows it.
The working routine
1
Pick the source still as carefully as for stills
Front or three-quarter, even light, neutral expression. In video the source is consulted thousands of times; a poor source is a thousand small errors.
2
Choose clips with kind motion
Moderate turns, steady light, the face visible for most of the duration. Violent motion and strobing light defeat any transfer.
3
Watch the joins before you judge the face
Hair crossing the face, hands passing, the turn away and back. The joins are where a video swap either holds or announces itself.
Where it earns its place
Re-casting
A performance in the wrong face
Motion captured or generated once is made hers, so the catalogue gains a clip without a new shoot.
Series
Clips that match the stills
The same face in motion as on the still covers beside it — one performer across every format in the set.
Loops
Short loops for the feed
A brief loop carrying her face cleanly at thumbnail size, where most viewers will ever see it.
Clip traits and their effect
| Trait | Effect |
|---|---|
| Face visible, moderate head turns | The steadiest transfer |
| Steady, even lighting | Skin tone holds across frames |
| Short duration | Fewer joins, cheaper correction |
| Fast spinning, occlusions, flashing light | Expect breakdowns; choose another clip |
Judge it as a clip, not as frames
Pause on three frames and the swap may look perfect; play the clip and the joins tell the truth. Judge in the three viewings used everywhere at the render desk: the character across the whole duration, the joins at full attention, and the loop point repeated. A transfer that passes all three is finished work. One that fails is corrected at the source or the clip choice — not by spending finishing credits on top of it.
How much does a video face swap cost?
31 credits a job on the video_face_swap model, shown before you confirm. Failed jobs refund automatically.
Whose face may be the source?
Your generated character’s, your own, or an adult’s with documented consent — the same line as every transfer at 51CgPro.
Why does it break at turns?
The turn is the hardest join: angle, light and hair all change at once. Moderate turns and steady light are the pattern that holds.
Should I swap before or after upscaling?
Swap first, at working size, and judge it there. Upscaling is a finishing pass over a clip that already belongs.
Are clips and sources private?
Yes. Everything rests in your account until you publish a result yourself.
