My way:

autosave replays
use AC replay to determine the meaningful clip, save the clip as a new AC replay
replay the clip using Ctrl+L to display driver names while capturing with Windows Game Bar (built into Windows, AFAIR to start/stop recording you need to press Alt+Win+R
use one of many available free and simple tools to cut/join the video if necessary (MP4Joiner, MP4Splitter, My MP4Box GUI)
Upload to youtube (or whatever)

BTW thanks for stressing that the incident should be shown from cockpit AND TV cameras, I missed that and only uploaded one TV viewpoint per incident, maybe this is why I haven't heard back about my reports. (meaning also that you should take my method with a grain of salt, so far my reports haven't been successful ;-) )
