Why is export from Screenflow 9 or 10 MUCH slower on the new M1 Pro MacBook 14" compared to the M1 MacBook Pro 13"?
You can see the export settings and then the difference in export speed from the MacBook Pro 13 M1 (16GB - Bir Sur 11.6) ) on the left vs the MacBook Pro 14 M1 Pro (16GB - Monterey 12.0.1) on the right.
Export time is more than twice as slow on the MB 14 Pro in both Screenflow 9 and 10 (latest versions).
Is Screenflow not optimised for the new MacBook Pro M1 Pro, or has it got anything to do with Big Sur vs Monterey MacOS systems, I can't test either of these...
I truly hope Screenflow can be optimised and/or fixed to take advantage of the M1 Pro/Mac chips like Final Cut Pro X 10.6 and Davinci Resolve 17.4!
Thanks for that but in order to test please have matching operating systems since changes Apple made in Monterey may have an impact. We're still testing.
We also need complete specs on both as there are a variety of CPU/GPU configs and cores. RAM may be a factor and whether anything else was running in the background.
The same document should be tested on both systems.
Additionally, you could give us your document so we can test it directly on our systems.
I've noticed a similar issue. I'm on the M1 Max 32 GPU codes and trying to do the H.264 encoding with the Hardware Accelerated Apple H.264 enabled. Before, when trying with just the 8 Core CPU, it completed my transcoding in 2 minutes. With the Hardware Accelerated Apple H.264 enabled, it took 8 minutes.
A very strange issue that I found is when exporting the video with the CPU, it started off but then all of a sudden the monitors went black. The only way to get them back on was to unplug them and plug them back in.

Are you saying that hardware-accelerated encoding is slower than normal encoding on the same computer? Can you provide more details on the sources and export settings?
I tested the exact same recording on the M1 Max Macbook Pro (left) and the M1 Macbook Pro (right). Using the "Fast" hardware encoding setting, it took significantly longer with the M1 Max.
I know that this is a bit repetitive. I finally had the time to directly test an "apples to apples" comparison with the M1 and M1 Max. I know that this isn't a Screenflow issue as it does appear to be something more globally affected the M1 Max, but hopefully Screenflow's pull in raising this issue to the Apple devs can yield some results more so than what I can.
Or, did Apple reduce the number of media encoders on the M1 Max to make room for more ProRes?
FYI, just adding a +1 that I have the same issue. Testing video encoding/export speeds (with ScreenFlow) was the first thing I tried on my MBP M1X Max and Screenflow on my M1 Air said it'd take 25mins to export a video, M1X Max said 45 mins (and the CPUs, GPU were underutilized).
I understand that this is an Apple/OSX issue, but I'm following this thread too, if you have any useful updates or info about this issue, please update this thread too.
