Frame Glitch (actual bug) (in after effects and premiere) (pls help)

[DEGplayz]

I was trying to make a montage on after effects and all of a sudden I experienced this glitch when I played back the video. The resolution and fps of the compostion was 1280x640 60 fps and the clip's resolution and fps was 1920x1080 50-60 fps (sadly not constant it was variable framerate I think). I thought it was a glitch because of compostion settings but when I made a new compostion with the exact details (dragged the video to the make comp button) it still showed the glitch. The glitch occured multiple times and seemed to divide the video in two halves. Here's a picture of a non glitched frame, and of a glitched one non-respectively.

Please help, The same issue occured in Premiere Pro though I don't have any screenshots.

Hardware:

I5-4300U - CPU
Intel HD Graphics Family - GPU

8 GB DDR3 - RAM

1920x1080p 75 hertz - Display

I would suggesttryingto purge your cache, retsart AE or maybe even reboot your system.  Although i have to say with you hardware specs I would be surprised if your weren't running into graphical glitches.  It could just be your system not being able to handle what youre throwing at it.

Don't worry I found out the problem, it was a graphic issue, I just turned off hardware acceleration in preferences and and change project settings from Mercury GPU Acceleration (OpenCL) to Mercury Playback Engine Software Only.

THANK YOU! I found your issue through googling my own issue, which is similar.

I use NVidia GTX 1070 on a stationary computer (along with Intel i7 (8th gen)) and couldn't quite figure out why this happened. 

What helped for me was:

1) Close any currently open project

2) Disable Mercury GPU Acceleration (OpenCL) and change it to Mercury Playback Engine Software Only

3) Clean all cache files (Edit > Preferences > Media and Disk cache)

4) Open any project that had the issue and validate that the issue is now gone

I would also suggest if you don't want your playback and rendering be slowed down, is do the solution above if it works. After that, you can reverse the process, but the bug won't be present anymore. Works for mine! Thank you.

Ahhh...nevermind the bug is back. Just try to deal with the buffering for that project

I've been getting this bug for more than 5 years. It's 2025 and still the bug exists even now. Instead of adding new features, may be the AE team should focus on fixing the simple existing bugs like these first. Using Mercury Software Only workaround works, but it's crutches AE video decode performance. It's like working using a 90s software.

Hi Shashank,

Thanks for writing in. Do you mind sharing more details on the issue? What are your system specifications (CPU, GPU, RAM, OS version)? What are the details of the media you're working with? Feel free to share screenshots.

Thanks,
Nishu
