Do multicams in Productions cause lag?
Hello,
Our post place has been encountering terrible lag/slowdowns in our Premiere Productions workflow which has been working for us for the last few years or so. We’ve been on Premiere 25.6.4 for 6+ months and have been experiencing the slowdown in the last month or so. What’s recently changed is that we’ve changed our features and episodes ingest workflow to incorporate multicams – which is why I think this is to blame. A few multicam sequences have proxies that have the hi-res attached if that makes a difference. However, MOST of the time, we have the Prores Proxy attached to the source low res H264 file.Other AEs have voiced our H264 dailies and autosaving/scratch disk overload as possible causes. My problem with these is we’ve had larger projects in the past with H264 dailies and haven’t had slowdown until now. We did change our scratch disk location about a year ago, and I can’t remember if we had as large projects as we do know, but our previous scratch disk location still meant we all shared 1 folder to dump our scratch disk files in.
We’ve gone through the usual troubleshooting stuff including, but not limited to: emptying cache folders, keeping projects under 7 MB, restarting our media servers, rendering sequences, proxying, and quarter sizing resolution when playing back. Nothing seems to be working. The lag also seems to happen indiscriminately? Sometimes one person is experiencing lag in the same production that someone isn’t.
Has anyone heard of multicams causing severe lag? Or does anyone have any advice on how to troubleshoot this? Should I push for us to have 1 Production without multicams to compare with?
Specs: Mac Studio, 64GB, footage: mixed prores and H264
