compressor slower than handbrake by a lot with my project?

So I have tried compressor and it seems with reasonably the same settings as handbrake it is a lot slower and will take 50 minutes to 1hour for compressor to complete while handbrake seems to say 20-23 minutes to complete their compression?


Sorry for all the images just want to see what settings ima getting wrong etc. Thanks for all the help! :)

The Activity Monitor is really kind of meaningless, especially with Apple Silicon. The software to hardware interface may be completely different for the two applications, so comparing AM behavior doesn't really tell you anything. Some Macs have hardware decoding/encoding for specific codecs on the chip. Others don't. Some have H.264, some have HEVC and H.264. Decode is a factor in performance speed as well as encode. Drives are a factor also.


You just need to run actual tests for time and quality on the media and see if it works for you. You have both applications you can test them against each other.

There's another point to consider - Handbrake utilises 100% of CPU, and almost no profile can engage GPU. So with 100% CPU load modern M1-M2-M3 Macs can shoot up to 108C temperatures on CPU, then fans kick in, and it becomes more or less manageable but still Handbrake stresses CPU to max. While COmpressor is never using 100% of resources perhaps with idea to keep overall responsiveness of OS high for other concurrent tasks. So Compressor is more gentle on you Mac and less likely to fry it with a 2 hour long export!
