Hi @BridgeInspector -
Welcome to the forums!
Videos recorded in Cockpit are stored onboard your computer, not on the vehicle!
For those recorded in the standalone Cockpit, those show up in your user’s home folder, under Cockpit (alongside Documents, Downloads, etc.)
For those recorded in the browser extension, you’ll need to connect the vehicle, open the Cockpit interface, and process / download the videos from the video library within Cockpit.
They will download as .mkv videos with .ass subtitle files, you can transcode these to MP4 and “burn in” the telemetry subtitle files if you like.
