Hello, I built an open-source app to add telemetry overlays (depth, temperature, tank pressure, NDL/TTS, etc.) to scuba diving videos. It imports Subsurface dive logs and auto-syncs with camera footage using timecodes. Free, cross-platform, no account needed. Just good ol' desktop software!

Here is an example of what it can do: https://youtu.be/tiPXv838EXU

I hope it's useful to some people!
