Burn in captions and overlay graphics
PostLumina burns SRT or ASS subtitles into video, Korean included, and puts a logo or title graphics over a whole folder of clips, on your own machine, when you ask Claude Code or Codex. You check a sample from one or two clips before the whole folder runs. Subtitle timing and layout can be checked before delivery.
Burn these subtitles into the video and put our logo top-right.

| Graphics | Logo overlay, title graphics |
| Checked before delivery | Subtitle timing and layout |
| Output | A PostLumina Output folder in the project, or a folder you choose |
How to do it
- Add the folder to PostLumina as a project. It indexes every clip's format, duration and tags.
- 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 clips. Once you like it, the whole folder runs, and the new files land in the project's PostLumina Output folder.
