Premiere playhead jumping a few frames back when playing in timeline

[mronkain]

I have a curious problem with my work PC. It occurs with any video I've tried so far. Scrubbing works smoothly, but when I hit play in timeline, the playhead starts jumping a few frames back during playback. There is no apparent load on system (memory, CPU or SSDs), I have Ryzen 7 2700X (8-core) CPU, 32GB of DDR4-memory, RTX 2080 Ti adapter, two SSD disks, a 4K and a FullHD monitor. Videos play back just fine on Windows. I've tried several codecs, wrappers and resolutions, they all behave the same, even a 720p video.

Any ideas? I didn't find anything on Premiere settings that could cause this. I've also flushed the Media Cache (in fact I completely relocated it and deleted the old one).

Try resetting the preferences:

If that doesn't work, try resetting the Workspaces:
Reset a workspace
Reset the current workspace to return to its original, saved layout of panels.
1. Do one of the following:
• Click the Workspace menu icon and select Reset to Saved Layout.
• Choose Window > Workspace > Reset to Saved Layout.

If that doesn’t work, try updating or rolling back your graphics driver directly from the video card manufacturer’s site.

If that doesn't work, try creating a new project and import the old one into it.

Hi, I got the answer from the Adobe User Group Finland: In the audio preferences I had microphone defined as audio input. When I disabled it, things started working smoothly.

THANK YOU!

I could not for the life of me figure out why this was happening.

You rock! Installed a new sound card then the first project I opened after had this insane stuttering issue. Knew it had something to do with the hardware but couldn't figure out what. You saved me from hours of headache - thank you!

Brilliant thankyou this has saved a huge amount of wasted time as I would not have thought a video playback issue would be caused by audio settings. In my case I chaged default input to No input to bypass the blackmagic card.

OMG! Thank you so much! Had this problem last year and couldn't figure it out after coming up with a ton of footage from some event. I was forced to edit everything on my old laptop. Now after a whole year again! Just finished an event again, reinstalled my win 10 and after importing all the footage it started happening again!!! Just tried this and it works! THANK YOU!!!

Thank you SOOOO much, for three days i was trying to sort this thing out and it was the same issue in audio hardware preferences audio input was from another app which made video playback stuttering! Thank you a lot!
