Random glitch in h264 video export on adobe premiere/media encoder
Hi Guys,
I'm a video editor and recently upgraded my system with an Intel Arc A750. I'm really happy with how it performs during rendering in After Effects and Premiere, but I'm experiencing a strange glitch during H.264 export, as shown in the image.
During editing in Premiere, no errors show up, but after export (in Premiere or Media Encoder), some random glitches (just one frame long) appear in the video. If I export the video again, the glitch will always appear in the same spot, but if I change something in the composition, it may move or disappear.
I've tried changing the export parameters, but nothing changes. If I export in MOV/ProRes, no glitches appear, but if I try to convert the ProRes to H.264, the glitch comes back. I've tried using an older version of Premiere/Media Encoder (2023), but the problem persists. I've also downgraded my Arc driver, but I still had the same problem. I exported the video without hardware acceleration (only software), and everything was fine. I also swapped my Arc with an old NVIDIA 980 GPU, and the video rendered correctly.
I strongly believe the problem is with the Arc GPU, maybe an issue with the driver or Adobe? I've spent a lot of time trying different configurations, but I still have the problem...I don't know what else to try now! I googled the issue, and the only similar problem I found was this post without any clear answer: https://community.adobe.com/t5/premiere-pro-bugs/premiere-pro-rendering-with-intel-arc-gpu-strange-glitch/idi-p/14277932.
Any help is really appreciated!
My configuration:
cpu intel 12600k
motherboard asus ROG STRIX B760-F
ram corsair ddr5 2x16gb 6000mhz
gpu intel arc 750
adobe premiere/after/mediaencoder 2024.5
