Poor Optimization for Timeline Playback; crashing with DNxHD codec
Hey all, I've been trying to edit a video but the incredibly delayed and choppy playback window is making that nearly impossible for me. I searched online for solutions, including things like reducing playback quality and effects, but that didn't work. During this, I found out about video codecs.
I had been using the NVENC H.264 codec for recording; I record stuff through OBS. I wanted to record a game and my webcam in full definition to be able to cut between them while editing, so I set my OBS canvas size to 3840x1080 and recorded like that. Importing this file into Express is when the playback was simply far, far too choppy to edit properly with, though these problems have always happened.
While researching this, I found out that many people claim the DNxHD codec works very well in Hitfilm, so I looked for a way to transcode my file into that codec to solve this problem. MPEG Streamclip seems to be a commonly used program to transcode to DNxHD, but I couldn't get it to work; it always crashed. To be clear, I recorded a 6 second clip in 1920x1080 with my original codec to test, assuming things could go south with the real clip due to the length.
I found another thread talking about other options to transcode to DNxHD, but none of the options there worked. Video2Video didn't ever launch, and ClipToolz2 is no longer available, nor is 3. Seems there's a V6, but I don't know whether or not it works and there's no free trial.
I found two other programs that had free trials that converted to DNxHD codec in the .mov container, but importing that to Hitfilm caused a near instantaneous crash. I tried multiple times, and reinstalled Hitfilm, no dice. This was true of both files from these programs. Normal .mov files work just fine in Hitfilm, and changing those DNxHD encoded files back to .mp4 didn't help either. The only thing I could conclude is that 6 (or 3) second clips encoded in DNxHD caused immediate crashes in Hitfilm.
So... I'm now at a complete loss for what to do. DNxHD seems to be a dead end at the moment in terms of smoothing out timeline playback, but no other methods have made any headway either. Does anyone have suggestions? Something obvious I missed, hopefully?
