Video Head Swap is two calls, not one. The first, video-analyze, watches a 5-to-30-second clip and returns one preview still per head it tracks, numbered 0, 1, 2 in a fixed order. The second, video-edit, takes that analysis's task id, the positions you picked, and one to three reference photos per position, and returns the clip with those heads replaced — face, hairstyle and hair colour included — while the body, wardrobe, motion and original audio stay as shot. Analysis costs $0.08 per request; the edit is $0.064 a second at 480p or $0.12 at 720p, and the two calls must agree on resolution.

The verdict

We ran one content-ladder probe on each call on 19 September 2026, both on footage past our adult-content rung, and both rendered as expected: the analysis returned correct preview stills and the edit applied the swap with the rest of the frame untouched.

Use it only on footage you're authorised to edit and reference photos of people who have consented to appear in the result.

Key facts

  • Content ladder: one probe on each call, run on 19 September 2026, rendered as expected.
  • Scoring: see the score card on this page and the Video Head Swap test report for run detail.
  • Price: analysis $0.08 per request; the edit $0.064 per second at 480p or $0.12 at 720p.
  • Limits: clips of 5 to 30 seconds; one to three reference photos per head; both calls must use the same resolution.
  • Sources: the scoring rules are on our review methodology page, and the full parameter list is on the Video Head Swap model page.

What we liked and what held it back

What we liked

  • The numbering is stable enough to build a workflow around. Analysis returns previews in a fixed order — position 0 is always the first still — so you can look at the pictures once and reuse the same object_index values in the edit call.
  • Two people crowded together is the deliberate hard case, and it's handled as a hard case, not ignored. One of our published examples shows two heads seen from behind, shoulder against shoulder — exactly where a tracker could lose track of who's who — with each head still coming back as its own numbered preview.
  • Everything but the head stays put. Body, wardrobe, pose, lighting, camera work and the original audio track all pass through the edit call unchanged; only face, hairstyle and hair colour transfer.
  • Up to three angles per head. Sending more than one reference photo, ideally from angles close to the footage, gives the model more to match against than a single portrait.
  • Mismatches are rejected, not guessed at. Sending a video_url or resolution on the edit call that doesn't match the original analysis fails the request outright rather than quietly using the wrong tracking data.

What held it back

  • It's two calls and a stored task id, not one request. You need to run the analysis, read back the previews, decide which positions to replace, and only then call the edit — there's no single-step version.
  • The resolution has to match across both calls. Analyse at 720p and you have to edit at 720p; there's no field to change your mind between the two calls.
  • The neck seam is where this endpoint succeeds or fails. Because the whole head transfers, mismatched lighting direction, skin tone or head angle between the target and reference shows up right at the join.
  • A head that never becomes clearly visible may not get tracked at all. If someone's head stays turned away or off-frame for the whole clip, the analysis call may simply not produce a preview for them.
  • No prompt, no mask. You can't steer the swap with text; the reference photos and an optional seed are what you have to work with.
  • Clips longer than 30 seconds or shorter than 5 aren't accepted. Trim or extend footage to fit the window before sending it.

What we tested

We ran one content-ladder probe on each call — video-analyze and video-edit — on 19 September 2026, both on footage past our adult-content rung. Both rendered as expected: the analysis call tracked the head and returned a correct preview still, and the edit call applied the swap while the rest of the frame, including everything at that rung, came through untouched.

Two heads, tracked apart. The published video-analyze example deliberately uses two people seen from behind, shoulder to shoulder, with no faces visible from the front — the case most likely to confuse a tracker into losing count. Analysis at this difficulty still returns one preview still per head, correctly numbered.

How far it goes

Video Head Swap doesn't generate new content — it redraws a head onto footage you already have, so what ends up in the result depends on the footage and reference photos you send it. Our one probe on each call, both run on 19 September 2026 on footage past our adult-content rung, rendered as expected: the analysis and the edit both produced correct results with the rest of the frame unchanged. The page label is Uncensored: we add no content filter on our side.

Not tested yet: every content-ladder rung on both calls; clips with more than two tracked heads; the shorter and longer ends of the 5-to-30-second window.

Use this endpoint only on footage and reference photos you have the rights to use, and only when the people in the reference photos have consented to appear in the result.

Alternatives

  • Only the facial features, not the whole head? Video Face Swap keeps the target's own hair and just moves the features, at $0.0325 per second, no separate analysis call needed.
  • The same head swap, but on a still image? Head Swap does a single-image version, at $0.013 per image.
  • Replacing the whole figure, wardrobe included? Video Character Swap uses the same two-call analyse-then-edit pattern but swaps the entire person, not just the head.
