ISSUE - Poor hardware encoding quality - Mac M1 PRO chip

The quality of exporting from Premiere Pro using hardware encoding on the new MacBook Pro with M1 PRO chip is extremely poor. I've tried exporting with multiple different projects and footage but the quality when exporting with hardware encoding is pixelated and blurred - the file size is also significantly smaller than the estimated file size.

There is no issue with software encoding and footage is as expected.

I've tried Premiere Pro 2022 and also gone back to 2021 and tried opening with Rosetta instead, still hardware encoding into H264 is extremely poor quality with file sizes less than half the expected file size. This only happens with hardware encoding.

    This is exactly the same as I reported with the original M1 MacMini and seems to be an Apple flaw, possibly in hardware. Encoding using Apple's Compressor also gives the same poor results. Both programs use the same Apple Video Toolbox API.

    There is a bug waiting to be fixed there, it has been reported by others. In the meantime you can use AfterCodecs for Premiere Pro and Media Encoder and After Effects
