Batch-convert frame grabs and images
PostLumina converts a folder of frame grabs and images to PNG, JPG or WebP, on your own machine, when you ask Claude Code or Codex. Say the size and format once, and every image in the folder gets the same treatment. The new files go to a PostLumina Output folder; originals are never overwritten.
Turn every frame grab in this folder into a 1080p PNG.
| Image out | PNG, JPG, WebP |
|---|---|
| Size | Say it in the sentence, such as 1080p |
| Output | A PostLumina Output folder in the project, or a folder you choose |
| Custom | When no built-in tool fits, your assistant writes an ffmpeg filter expression; PostLumina checks it is safe before it runs |
| Not covered | Generating new images |
How to do it
- Add the folder to PostLumina as a project.
- Say the sentence to Claude Code or Codex, in your own words. Your assistant works out the steps; PostLumina runs them.
- Look at the sample made from one or two images. Once you like it, the whole folder runs, and the new files land in the project's PostLumina Output folder.
