But based on the M1 performance, I think I will keep my powder dry for the rumored M1X or M1Z models, which should start off at least 70% faster than the M1. In FFmpeg you can pass the parameter like this: ffmpeg -i INPUT.mkv -c:v libx265 -preset ultrafast -x265-params lossless1 OUTPUT. ![]() That way you can copy audio, chapters, and what have you before encoding video to h265 Atemu12 4 yr. ![]() If your files are different codecs, use mkv. ![]() The true import of this is that the Macbook Pro M1, which also has a fan and therefore will perform virtually identically to the Mac mini M1, is going to completely obliterate the 13" Macbook Pro 4-core i5 I just bought in June. If you all your files are h264 then you can just copy the audio stream and encode the video to h265 (quality loss is to be expected), then put everything in an mp4 container. Currently only HEVC (x265) and AVC (h264) are supported for video codecs. Compare to the i7 mini, which is very warm to the touch, with a blast of hot air from the rear vent. This tool allows bulk conversion of videos using ffmpeg. I'm doing some x264 -> x265 software encoding right now on my newly-arrived 8GB RAM Mac mini M1, and the performance under the Handbrake 1.4 beta 1 appears to be on par with my 2018 32GB RAM Mac mini 6-core i7 in terms of frames per second (they're churning away on the same file right now), which is somewhat less than I expected based on reported Geekbench scores, but the Mac mini M1 remains very responsive and its fan, although running, remains silent and there is very little heat coming out of the machine - either the case, or the rear vent.
