"Could not start playback" in Trimmer after changing frame rate for clip
So yesterday I had a little play on on Hitfilm (I had previously been using Premiere Pro but let the subscription lapse) and I imported some video clips that were filmed at 119.88 fps. I was going to slow the clips down to 23.976 fps so I right-clicked > Properties and changed the frame rate from there.
This led to a problem in the trimmer area. The clip would only play for the duration of the audio, then is would stop. So for example a clip that was 5 seconds @ 119.88 fps became 25 seconds @ 23.976 fps. But when I clicked to play the clip in the trimmer the playback ended after the original 5 seconds. If I scrubbed any further and clicked play the "Could not start playback" error was showing.
I read about a very similar topic on here from 2017 and a fix was supposed to be implemented back then. I can't find the link now.
Whilst I can still scrub through the clip to find my in/out points, I can't play it in realtime, which is pretty annoying.
Is there an actual fix for this? Or an option in the backend that I'm missing?
