I've just purchased PD 15 as a replacement for a video editing product no longer supported. I suspect the problem I am having is fairly common and simple to resolve but I haven't been able to find an answer in my searches (maybe using incorrect terminology in my searches).
I am typically working with input files from a GoPro and an Olympus TG-4 at 1080p @60fps and 1080p @30fps respectively. My PC is fairly old, an i5 with 4gb ram. My system disk is at 30% capacity and recently defragged, video disk is essentially empty, I just have a few small sample video files for PD testing purposes. Running a fairly trim version of Win10.
When I import video and preview, I see clean footage. When I move some footage to the timeline and preview (before or after edits), I get jerky output with the odd flash of green screen. It doesn't seem to matter whether I am in HD preview or normal. If I go back to the Media Content pane and preview from there, I can still see clean footage.
If I render, the output is pretty much the same as the timeline preview. It seems worse if I change the resolution, say step back to 720p. My 2 initial problem causes were frame rate mismatch between input and project, along with performance capabilities of my PC. I've played with frame rates and don't think that is the issue.
In terms of PC power, I've had zero problems with my old editing package (trakaxpc) using the same input files (often editing up to 2gb files). I know if I switched in a solid state drive or upped the memory, that would be useful but want to understand the issue better first. Similarly, I could replace the PC given its age, but since it performs well for all other products I use, I don't want to unless I know that PC performance is the issue.
I'm interested to hear if anyone has ideas or could point me towards other threads with the same theme if they exist.
thanks in advance.
