Hitfilm occasionally freezes in 2021.2 update
I am doing a project that is over 30 minutes long, and still more to go and am editing it in segments and is a 2 camera project, that is, main and B roll and am using a different technique for proceeding due in part to the subject. Assembling is putting down most of the main camera clip (in this case, chapter 1 via GoPro) with good audio, trimming out the extraneous bits at the beginning as I ID and clap to start a take, keeping the entire thing (almost) of the good take as a base timeline.
Then I drop in the B roll off a Canon Vixia camcorder with scratch audio that's trimmed to the good take at the beginning, then I get them aligned up via wave forms of both audio tracks to sync them. Once synced, I then can delete the scratch audio from the Canon by unlinking and just delete the audio, leaving the B footage in place, and leaving the GoPro with my wireless lav for the good audio and then begin to cut out the parts of the B roll (technically, camera 2) so I am "cutting" between them. However, Hitfilm does not crash per se, but goes unresponsive for 30 sec's to a minute before resuming and it didn't do this before the update, even when editing a longer video.
