A video player focussed on 360 videos.

I got a 360 camera (GoPro MAX v1) for my bicycle, after re-discovering bicycling during COVID. I soon found it was fun to review the video after a ride, but the software was a bit clunky. Upgraded to a DJI Osmo 360, and found the software likewise powerful, but still not what I wanted.

As an audio video developer I knew I could make it work the way I wanted, and this year I finally set about doing that: https://recap360.app (macOS-only at the moment).

It’s a ~5MB download from the macOS app store; no in-app ads, no accounts, no ~GB download. It loads the video of a 5-hour bike ride in seconds, direct from MicroSD. Complete with a map overlay & graphs of various internal metadata. (Speed, altitude, ascent rate, but also internal temperature etc).

It’s been fascinating to see the various tradeoffs the camera vendors make; how much in-camera stabilization & rolling shutter compensation vs how much to leave to the player. Also interest ing is how the metadata is recorded in the file; some document them, most don’t.

Started with GoPro MAX, added DJI Osmo 360 & Insta360 support. More coming soon. Even plays dash cams & body cams (Vantrue & Boblov; I was curious to see how they stored GPS data).
