I'm new to Rush. When editing a set of 4K 30fps clips on my desktop I constantly get jittery / frozen playback when editing. I've noticed that this happens only during high CPU usage. Jumping forwards, backwards and rewinding triggers the high CPU usage. Even stepping forward/backwards frame by frame several times will trigger high CPU. If I wait until the CPU usage drops to zero, I can make a few edits before high CPU starts again. But there is a lot of waiting. Exported video playback is just fine.
The only suggestion I've seen here is to set preview quality to low which I've done.
I'm using a Windows 10 desktop. It's a powerful computer: Intel Xeon, dual-processor, 6 physical cores per CPU, hyperthreading, so 24 logical processors. Quad channel memory. I have a decent but not super-powerful graphics card. Rush does not seem to make any use of the graphics card, and uses less than half of the PC's RAM.
I know 4K is demanding, but I don't see how it would be possible to edit at all on a phone, tablet or slower PC. Am I missing something?
Thank you for reaching out. I understand that you're having trouble with the playback in Premiere Rush.
Let us know, we're here to help.
The info you requested:
Rush version 1.2.12 (Build 10)
Six MP4 clips; 4K @ 30 fps; length of 2 to 5 minutes each; total size 16 GB
Was not sync'd to cloud; but just turned on sync
The clips are visually very dense; I'll look at some other media to see if it has the same issues.
GPU is an AMD R9 390 with 8GB VRAM. It is not being used by Rush.
Updated to latest AMD drivers today after posting this topic; same jitter problem.
I'm surprised the GPU is not listed as supported, the same chipset (mobile version) looks to be supported on Mac.
Any resolution? My CPU is through the roof. 80% from Adobe Rush. I can't edit at all. It freezes so badly that the program won't even close without being forced close. 5 months ago I could edit videos. It was slightly painful but tolerable. All of a sudden I can't get through 30 seconds without the program busting, and it looks like that's because my CPU can't hack it. Also Windows 10 on a pretty decent laptop! I'm at a loss, and I don't sync to the Cloud. I also don't understand how anyone could possibly do this on their phone. Thanks!
I am also having horrible freezing and SUPER LONG rendering (if it can do it without error code 3) as of 2-3 weeks ago. It was fine and then after the holidays I'm trying to edit videos for my YouTube channel and it's almost impossible. It's my GPU that is totally maxed out. CPU does not seem to be affected.
I'm running Adobe Premiere Rush version 2.6.0 (Build 52)
I have tried the following:
here are my system specs:
I store completed videos and data on an external drive. I've started also putting unedited data on another external drive to have space. The videos I'm editing are on the laptop's SSD.
I would really appreciate some help to figure out what is going on and why Rush is so slow and why it renders so slowly too. That part of my business has almost come to a standstill. Thanks.
