Does anyone have any ideas why I would get occasional jerkiness on the playback of rendered previews? It even happens on sequences whose rendered previews in which the clips match the sequence in frame rate and size (most noticeable in my drone and animation footage, single frames at 1080p). It happens whether the restitution is full or 1/4 (albeit, I can't see any difference between the two). And it won't repeat. If I play the area that "skipped" again it unusually plays fine the second time around. I have lots of RAM (32GB), a fairly fast processor (I7 5960x) and fairly good graphics card (GTX 1060 6 GB). Any suggestions?
Sorry to hear about your issue. Ideally, the playback speed in Adobe Premiere Pro is dependent on various factors (effects applied, sequence complexity, media format, and resolution etc). The system specifications on your computer are good enough to get smoother playback but it can vary for different sequences and projects. We'll need more information to troubleshoot the issue better:
Have you used any GPU accelerated effect?
Does it happen with every project?
Where have you saved the media cache?
Please check if GPU acceleration is enabled by following this path: File > Project Settings > General > Video Rendering and Playback.
Thanks for the suggestions. Yes, I have the GPU CUDA acceleration on. It happens with all projects with rendered timeline files. The media cache is on the boot SDD drive but it's on a D drive partition separate from the C drive software. I have tired keeping the rendered files on both the SSD drive and an older 10k rpm hard drive, with the same results. The jerkiness is infrequent, doesn't repeat in the same spot, but it's slightly weird. I can live with it, though once I know that it won't repeat when its all rendered to a file.
