P-Video Replace: Video Character Replacement Online
Bottom line
Pruna AI's budget character swap for existing video: 720p/1080p, from 2.4 credits/sec, keeps source audio. Bring a source video and a character image to the Animate Replace tool — VdoBloom prices the swap in credits up front and refunds automatically if a run fails.
P-Video Replace is the value option in VdoBloom's Animate Replace lineup. Built by Pruna AI, it takes an existing video and a reference image, then swaps the on-camera character for the one in your image while leaving everything else untouched: the motion beats, the camera moves, the lighting and the background all carry over from the source clip. Uploads accept an MP4 source video up to 100MB and a JPG, PNG or WebP reference image up to 10MB.
Its pricing is the clearest reason to pick it: 2.4 credits/second at 720p and 4.8 credits/second at 1080p, well below Kling 3.0 Motion Control's 8-10.8 credits/second in the same tool. A 10-second clip costs 24 credits at 720p or 48 at 1080p -- cheap enough to run several character variations of the same source video for close to the cost of a single generation on the premium option. The model also preserves the source audio track by default and drives lip and motion sync from that audio, so talking-head footage keeps feeling natural after the swap.
It carries a MODERATE content label on VdoBloom -- stricter than the HOT-rated Wan family, but more flexible than STRICT-rated models like Kling or Veo. For UGC-style ad variations, where one script needs to be fronted by different faces, the combination of low cost and audio-aware syncing is the practical trade-off this model is built for.
What it costs on VdoBloom
P-Video Replace bills per second of your source clip: 2.4 credits/second at 720p, 4.8 credits/second at 1080p, with VdoBloom's standard estimate based on a 10-second clip -- 24 credits at 720p, 48 at 1080p. That's the lowest per-second rate of the two models in the Animate Replace tool; Kling 3.0 Motion Control runs 8 credits/second at 720p and 10.8 at 1080p for its higher-fidelity motion transfer.
Common problems and how to avoid them
Character-swap results depend heavily on how well your reference image's pose, lighting and framing match the source footage -- an image shot at a very different angle from the video's subject tends to produce visible artifacts. Since audio and lip sync are driven from the source track automatically, review a short clip before running a longer one if dialogue timing matters. If a generation fails outright, VdoBloom refunds the credits automatically, so testing several reference images against the same source video costs only what actually completes.
What creators use P-Video Replace for
- Producing multiple presenter variations of one UGC ad to test which face converts best.
- Inserting a consistent brand character into previously shot footage without a reshoot.
- Prototyping content formats by swapping yourself into reference videos before committing to Kling 3.0 Motion Control.
- Running several low-cost character-swap iterations of the same source clip before picking a final direction.

Frequently asked questions
How much does P-Video Replace cost?
2.4 credits/second at 720p, 4.8 credits/second at 1080p. A 10-second clip -- VdoBloom's standard billing estimate for this tool -- is 24 credits at 720p or 48 credits at 1080p.
What does P-Video Replace do with the original audio?
By default the source video's audio track is preserved in the output, and the model uses that audio to drive lip and motion sync on the replaced character, so dialogue clips stay believable after the swap.
What resolutions does P-Video Replace support?
Two output tiers, 720p and 1080p, selectable in the Animate Replace tool. The 720p tier costs exactly half the 1080p tier per second, and the exact credit cost is displayed before you generate.
How strict is P-Video Replace's content filter?
VdoBloom rates it MODERATE -- stricter than the HOT-rated Wan family but more flexible than STRICT-rated models like Kling or Veo. Failed generations are refunded automatically.
When should I pick P-Video Replace over Kling 3.0 Motion Control?
Pick P-Video Replace when you're iterating: at 2.4-4.8 credits/second it's markedly cheaper than Kling 3.0 Motion Control's 8-10.8 credits/second, keeps the source audio, and shares the same 720p/1080p resolution tiers. Pick Kling 3.0 Motion Control when a single hero clip needs its higher-fidelity motion-transfer approach and the premium rate is worth it.
What are the upload requirements?
A source video as MP4 up to 100MB, and a character image as JPG, PNG or WebP up to 10MB.
Is P-Video Replace open source?
There's no public information establishing this model's weights as open source. It runs on VdoBloom as a hosted model through the Animate Replace tool.
Does P-Video Replace work on realistic human footage, not just stylized clips?
Yes -- it's commonly used for both. Results depend heavily on how well your reference image's pose, lighting and framing match the source video, so testing at 720p first before committing to a 1080p run is a reasonable way to check quality on your own footage.
