Remake a viral short with your own cast

Paste a TikTok link or upload a short, and Percify breaks it into shots, then regenerates it with your face, character or voice.

Replicate a short takes a TikTok, YouTube Short or Reel (a link or an uploaded file, up to 2 minutes), breaks it down shot by shot, and regenerates it with AI. You can put your own face, character or product in place of the original subject, re-voice the spoken lines with a sample of your voice, and download the replica next to a side-by-side comparison with the original.

Replicate a short: paste a link or upload a video to start.

What you need

• A computer. Replicate runs in the desktop web app at app.percify.io/home/replicate, and it has a Replicate tile on the Explore page.
• A short under 2 minutes: a TikTok link, a YouTube Shorts or Reels link, or an MP4, MOV or WEBM file up to 50 MB.
• Optional: a photo of the face, character or product you want in the video, and 10 to 30 seconds of clean speech (no music) if you want the lines in your voice.
• Credits. Analysis costs 5 credits; generation is priced per clip (see below).

How to replicate a short

1. Add the source video

   Under 1 · Source video, paste the link and click Analyze (~5 cr), or click upload a video file. Analysis usually takes 1 to 3 minutes. When it finishes, you see the shot breakdown.

2. Shape the blueprint

   Under 2 · Blueprint you can:

   • Type one instruction in the remix box and click Remix all clips to rewrite every clip.
   • Under Star in it, upload your face, character or product to replace the original subject, then click Adapt blueprint to it.
   • In the cast list, use Swap this one to replace a single character, and Change voice to upload a voice sample for a speaker.
   • Pick which clips to generate: all of them, Hook only, or your own selection.
3. Choose how it renders

   Pick a model card (for example Closest Replica, Budget Replica, Precision Cuts, Motion Match or Re-imagine), a quality (low, medium or high), a Frame (Full-bleed, Original card or Blurred background) and Audio (Silent, Original, per clip, Original soundtrack, Upload track or Your voice). Optionally tick Burn in the original’s text overlays and Marketing cut.

4. Generate

   Click Preview the hook to test the first part cheaply, or Generate full replica. Both buttons show the estimated credits. Each clip usually takes 1 to 3 minutes.

5. Download or share

   When “Your replica is ready” appears, switch Text on or Text off, then use Download replica, Download side-by-side or Share, which copies a link anyone can watch. Past runs stay under Your runs & history.

How much does it cost?

Step	Cost
Analyze the short	5 credits, refunded if the analysis fails
Generate clips	Priced per clip by the model card, the quality and the clip length. The generate button shows the estimate before you click.
Star swaps and your voice	Swapping a subject into a clip’s frame and re-voicing lines with your sample are charged on top of the clips

Credits for clips that do not finish are refunded automatically. Budget cards cost far less per clip than Closest Replica, so preview the hook on a budget card first when you are testing an idea. See how credits work.

Is there a watermark?

Yes, on this tool only. Every finished replica has a small Percify mark in the top-left corner, as a disclosure that the video is AI-generated. The side-by-side comparison is labelled ORIGINAL and PERCIFY, with percify.io along the bottom. Other Percify outputs carry no Percify watermark.

Limits

Limit	Value
Source length	Up to 2 minutes. Longer videos are refused, not trimmed.
Uploaded file	MP4, MOV or WEBM, up to 50 MB
Links	TikTok, YouTube, Instagram, or a direct https link to an .mp4, .mov or .webm file
Remix instruction	Up to 300 characters
Voice sample	10 to 30 seconds of clean speech works best

Tips

• If YouTube or Instagram links are refused with “temporarily unavailable”, download the short and upload the file instead, or use a TikTok link.
• A TikTok or Instagram photo carousel is not a video. Paste a Reel, a TikTok video or a Short.
• Speakers without a voice sample keep their original audio, so you can re-voice one person and leave the other as is.
• Use a clear, front-facing photo for Star in it. A photo rejected by content moderation cannot be used.
