Hitfilm express 12 - Viewer slows down too much when playing or freezes (only video, audio plays ok)
I started to work on a project in version 11, where I use several 1080p .mp4 videos in a composite shot and a moderate load of effects on them as color grading transfer, auto light flares, speed and green screen keying effects.
My computer specs are in the lower limit of what is required for running Hitfilm, but in this case I think it becomes irrelevant since in Hitfilm 11 I got descent results, I've been able to manage my way to create the composite shot without performance problems (lowering viewer resolution, etc). I get a bit slow playback in the edit, but manageable.
The problem is that I'm not getting the same viewer's performance in version 12, I had to switch back to version 11 in order to continue working.
Playback in the viewer, even with the lowest resolution and quality, becomes too choppy (at least way more choppy than in version 11) and if the tape head is moved manually, it freezes while audio keeps playing.
Is there any setting that I need to consider to adjust in order to get a good viewer performance?.
