Hitfilm3 Express "could not play frame"; seems unusably slow,
I WANT to like HitFilm3, I really really do. Obviously it works or there wouldn't be a body of work associated with it, so maybe it's something I'm missing or doing wrong.
Windows 7 Pro 64bit; Intel i7 2.8GHz; 12GB memory; Radeon R9 Series 200 video card with 4GB memory.
I've got two issues. First: when trying to play heavily compressed video in the trimmer, I get the message "Could not play frame" or "Could not start playback." If I click off the clip in the media tab then back on it, the frame the head is on shows up. Still won't play though. (Dragged into the timeline, the clip will play after a long delay building the frame previews - I guess.)
The clip is about 32 minutes long, 1920x1080, 29.97fps, MP4, heavily compressed.
Second: HF3E seems unusably slow. I started with MTS files just off the camera, and anytime I would move the playback head on the timeline, click on a different clip, do something in the trimmer, HF3E would freeze for a good five minutes before whatever it was I'd done would register.
I tried creating proxy files - all I'm doing is editing, no effects or anything - but the process never stopped, not even after waiting overnight.
I then created low-res proxies using another program, and plugged those into the project (figuring I'd replace them with hi-res at render time), which resulted in the errors described in the first half of this post.
I want HF3 to work. Please help!
