About the Add Timecode to Video
A burnt-in timecode is what review copies use so that a note can say "at 00:04:12" and mean it, whatever player the reviewer is using.
This tool deliberately does not accept a free-text caption. Arbitrary text has to be escaped for the filter grammar, and a mistake there is a command injection - so the overlays offered are ones the encoder generates itself.
Questions people ask
What actually does the work?
FFmpeg, the same open-source toolchain most video software is built on. It runs as a separate process with a fixed argument list, a time limit and no network access. Nothing from your filename or your settings is ever passed to a shell.
Why does this one take longer than the other tools?
Media work is genuinely expensive: a re-encode reads and writes every frame. The job is queued so that a busy moment slows things down rather than taking the site out, and the page shows where your job is in that queue.
What happens to the file I upload?
It is stored under a random name that is not guessable, processed by an isolated worker, and deleted as soon as you download the result - and in any case automatically after 60 minutes. Uploads are never indexed, shared or used for anything besides producing your result.
Is it free, and do I need an account?
Yes, it is free, and there is no account, no sign-up and no watermark on the result. The project is funded by optional donations.
