Source video
Upload the clip whose motion, timing, framing, and general scene rhythm should stay in place. A stable source with a clear subject and readable action gives Replace a cleaner target than a busy scene with several competing subjects.
Source video + refs → replacement drafts
P Video Replace
Replace a subject in a source video with one to three reference images, then guide the result with prompt, duration, resolution, FPS, audio saving, and seed controls — a focused browser workflow for quick replacement drafts and motion tests.

Replacement workflow
Swap a subject without rebuilding the whole clip
P Video Replace is built for a narrow but common video task: keep the motion, framing, timing, and scene feel of an existing source clip while testing a different subject or visual reference inside it. Instead of starting from a blank prompt, you begin with video structure that already works and use reference images to steer what should appear in the editable area.
That makes Replace useful when a product shot, prop, character, or campaign asset needs a quick alternate take. You can use the same source motion to compare reference images, adjust the prompt boundary, and decide which visual direction is worth a higher-quality pass. It is not a full editing timeline; it is a fast replacement console for short drafts.
Replace sits between the freeform P Video AI Video Generator and the reference-motion workflow in P Video Animate. Use Generator when you only have a prompt or starting image, Animate when a still image should follow source motion, and Replace when the source is already a video but the subject needs to change.
What you provide
Three inputs guide a replacement
Replace works best when the source video, reference images, and prompt all point to the same target instead of competing for control.
1-3 reference images
Add one to three images that define the replacement subject or visual direction. Use consistent, rights-cleared references with similar lighting and angle when you want the result to preserve identity and material details.
Replacement controls
Guide the swap with a concise prompt, resolution, FPS, source duration, audio saving, and seed. The controls are intentionally compact so you can test one replacement idea at a time and compare versions fairly.
Workflow
From source clip to replacement draft in four steps
01
Choose the source clip
Pick a short source video with one primary subject, steady motion, and framing that already works. Replace is strongest when the original clip gives the model a clean motion track to preserve.
02
Add replacement references
Upload one to three reference images for the new subject or style. Similar angles, lighting, and visual detail help the replacement read as intentional rather than pasted into the scene.
03
Write the replacement prompt
Describe what should be replaced, what should stay stable, and how the result should feel. Keep the instruction direct: one subject, one replacement intent, one motion style.
04
Generate and compare
Run a 720p test first, review the swap, then adjust a single variable for the next pass. Saved generations stay in your library so you can compare each replacement attempt side by side.
Quality checklist
What to check before each run
Replacement quality usually comes from clean inputs rather than long prompts. Check the source, references, and output pass before spending a higher-resolution render.
Source clarity
One primary subject, simple foreground/background separation, and no unnecessary camera shake.
Reference match
Images that show the replacement subject with enough detail, similar angle, and clean lighting.
Prompt boundary
A clear instruction for what to replace and what to preserve, without extra competing actions.
Output pass
Start at 720p to judge fit, then move to 1080p only after the replacement direction works.
Prompting
Write prompts that preserve the scene
A good replacement prompt is less about style overload and more about boundaries: what changes, what stays, and how the swap should blend into the source motion.
Name the target clearly
Say which subject should be replaced before adding style. A prompt like “replace the product on the table” is easier to follow than a long mood description that never identifies the object.
Protect what should not move
Call out background, camera motion, hands, props, or lighting that should remain stable. Replacement results improve when the prompt separates the editable subject from the rest of the clip.
Keep references consistent
Three conflicting reference images can confuse the target look. If you upload multiple images, make them different views of the same subject or the same design direction rather than unrelated options.
Use seed for controlled tests
Hold the seed steady while changing one reference image or one prompt phrase. That makes it easier to understand whether a better take came from the reference, the wording, or the random variation.
Use cases
Where replacement drafts help
Use Replace for quick visual alternatives where keeping the same motion is more useful than generating a new clip from scratch.
Product swaps
Test a new product design, package color, or prop inside an existing source clip before arranging another shoot.
Social variations
Create several short replacement drafts from one motion clip to see which subject or visual hook reads best in feed format.
Concept testing
Swap a draft subject into a motion plate so a team can judge timing, framing, and visual fit before production.
Creative iteration
Compare reference images, seed values, and prompts while keeping the same source motion for a controlled test.
Campaign drafts
Preview how a brand asset, object, or visual motif might sit inside a clip for a campaign deck or review call.
Asset refreshes
Update the subject in a short clip while keeping the original motion, pacing, and audio direction intact.
Pricing
Replace is billed by source duration
P Video Replace costs 7 credits per second at 720p and 14 credits per second at 1080p. Start with a trimmed source clip and a 720p draft, then compare full credit packs on P Video Pricing.
FAQ
Replace questions
What does P Video Replace need to create a video?⌄
P Video Replace uses a source video plus one to three replacement reference images. You can also add a short prompt, choose resolution, set FPS, estimate source duration, keep or remove audio, and set a seed for repeatable tests.
How is Replace different from P Video Animate?⌄
P Video Animate applies source motion to a still image. P Video Replace starts from a source video and uses reference images to guide a subject replacement while preserving the motion, timing, and scene feel of the original clip.
How much does P Video Replace cost?⌄
P Video Replace is billed by the second: 7 credits per second at 720p and 14 credits per second at 1080p. Start at 720p while testing, then use 1080p when a replacement draft is worth a higher-quality pass.
How many reference images should I upload?⌄
Use one strong image when the replacement subject is simple and clear. Use two or three images when you need extra angle, material, or identity detail. Do not mix unrelated subjects in the same run.
What source videos work best?⌄
Short clips with one readable subject, stable framing, and clean separation between subject and background work best. Busy footage with overlapping subjects or fast cuts is harder to replace cleanly.
Should I keep source audio on?⌄
Keep audio on when the source clip has timing, ambiance, or sound you still want in the result. Turn it off for visual-only replacement tests or when the final audio will be added later in an editor.
Do I need a local GPU or editing software?⌄
No. P Video Replace runs in the browser as part of the online P Video workflow. Upload your source video and references, set the options, generate, preview, and download the result.
Can I replace any person, product, or copyrighted subject?⌄
Only upload and replace materials you have the rights and consent to use. Do not upload someone else's likeness, brand asset, copyrighted work, or private material without permission. Rights-infringing, impersonating, adult, and abusive content is prohibited by the Terms of Service.
