Footage strobing/flickering during playback

[mikek25490304]

I am editing a demo reel right now, with footage I shot in 2018 and stuff I shot in 2017 and prior. The 2018 stuff loads just fine. When I pull up the project from the reel I edited last year, it will playback OK for a few minute, but then the footage starts flickering to black, like a strobe effect, after a couple minutes of it working fine. Using premiere pro 12.1.0 (build 186). When I open the older 2017 project in my current 2018 project, then my newer footage even starts strobing and flickering. So whenever I'm trying to incorporate the older stuff, premiere just goes crazy. The older stuff is a mix of pro-res and h264 and MXF. I tried transferring the older footage to a different hard drive to see if the hard drive is bad, but I got the same problem on the new drive. Please advise.

Hi mikek25490304,

Sorry for the performance issue. How exactly you are opening the 2017 project in the latest version?

Are you converting it? If yes, create a new project in the latest version, import the old project file into it & check the performance.

Thanks,

Vidya

I've tried opening it normally (through converting the project file) and i've tried importing the project into another project, and i've tried importing it as a shared project. The best i've gotten is that it will work fine for 5 minutes but then footage starts strobing again, almost like there is something causing the playback to corrupt
