O3-OverlayTool

February 23, 2025 · View on GitHub

A Tool for rendering videos from .osd files recorded from the O3 Air unit.

NOTES

  • A portable version with a standalone executable has been added in the release section. Works without any libraries etc. I recommend using that one, it is a bit simpler.

  • This is a work in progress, there might be bugs.

  • The tool doesn't directly overlay over footage, it simply creates the OSD frames on top of a chroma key or a transparent background. The overlaying needs to be done in a video editor.

  • The best results will be achieved when overlaying over Air Unit DVR rather than goggles DVR.

  • Selecting "Transparent Background" will have better results because it maintains semi-transparency of the OSD font! It's also faster!

  • Works with files created with https://github.com/xNuclearSquirrel/o3-multipage-osd. Files created with Walksnail of Vista-WTFOS (on the newest update) are also supported.

Usage

To launch the GUI: -Run OverlayTool.py or the run.bat. -or download the portable release and run OverlayTool.exe (Windows only).

Required libraries

  • numpy, pandas, opencv-python, pillow
  • FFMPEG (when using transparent backgrounds) included now.

The portable version should work without any libraries.

TODO

  • Add support for other .osd file format. Such as Vista .osd files (done) or Walksnail .osd files (done).
