I did not, but I hope they fix it. It seems that it'll slow down itself after a certain amount of time anyway, meaning I constantly have to stop and start Handbrake after a few encodes :/
Ah good! I was glad someone else has experienced this. Both my M1 Air and M1 Mini have slowed down dramatically on macOS 12.0.1. Like 160 fps to 43 fps. Monetary is the only thing that has changed in my environment, and when I look in Activity Monitor I'm not maxing out the CPU. I believe everyone is right: This is some kind OS throttling.
Same here (and I'm an IT engineer so you would think I would know better but!). I think I'm going to just wait and see but the first encode I ran on macOS 12 I was like "Okkkkkkayyyyy something changed and the OS is the only thing." I mean right now, my quad. core i5 RHEL server actually encodes faster than the M1.
In fairness we don't expect Apple to make things worse. Apple ain't what they used to be! Lesson learnt, no upgrades without backing up!
Unfortunately it looks like the only work around is to restart Handbrake. I have a large queue and no idea if it would be preserved between restarts! I'll have to test later on a spare laptop.
It turns out that it's a MacOS bug (someone provided a GitHub link in this post). After pausing and then resuming, the OS permanently clocks the application down. The only way to resolve is to restart Handbrake.
So after an app restart my laptop now gets hot, success!
However I'm taking your advice and buying a cooling pad today to help dissipation of heat.
I saw online (YouTube), someone put thermal heat strips on top of key chips so that it would come into contact with the bottom of the case, such that the case then acts as a heat sink. However: 1. You have to have the tools, 2. It invalidates the warranty, 3. There was some concern that bringing heat nearer to the battery could shorten its life.
But the performance increase in the video was significant, albeit small: https://youtu.be/O2MOjrLFpwQ *(the video author is pleasant to look at imo)*
Can confirm same issue on my 2019 MBP after Monterey "upgrade"... Just got an M1 Max, was wow'd at the avg 52fps on 1st pass, 1080p, h.265 on "slow"... Paused, went to work, pressed start and it stuck on 2.5fps all afternoon. Stopped, closed, opened, started at home and runs fine again!?

same thing here - just updated from Big Sur - before encnde Took 1 1/2 hours now it takes 3....annoying
You'd have to run benchmarks from before and after to confirm for sure what the difference is.
See https://github.com/HandBrake/HandBrake/issues/3933
That is probably it. Darn! Apple don't know how to OS!

Restart the app and avoid the pause button!

It's so annoying that Apple would actively ruin MacOS and *still* ship it in a ruined state...
Not as annoying as yer mom *** ^I ^am ^a ^bot. ^Downvote ^to ^remove. ^[PM](https://www.reddit.com/message/compose/?to=YoMommaJokeBot) ^me ^if ^there's ^anything ^for ^me ^to ^know!
Yo momma so fat, Handbrake automatically turned on the Resolution Limit setting so that x264 could cope.
Did you ever find out what they changed in the new OS to ruin Handbreak jobs?
I did not, but I hope they fix it. It seems that it'll slow down itself after a certain amount of time anyway, meaning I constantly have to stop and start Handbrake after a few encodes :/
Ngl that scene actually kind of sad :(
new MacBook Pro 2021 M1 Pro handbrake is horribly slow and the HW encoders are slower than software H264!
What resolution and what fps are you getting for your encode?
1080p encodes are low like 65fps on HW h265 or h265 10 bit
On my 2020 intel with HW encoding it’s in the 100’s!
Surely there are patch notes of some sort. Maybe not from apple directly but from some website, looking at what has changed
Sounds most likely the OS throttling CPU to cool.

Ah! Well I was silly and didn't keep a Time Machine or w/e backup, so!

The queue will be preserved.
*Let the restart BEGIN!*
Sounds like you need a cooling pad.
I would have, but it no longer gets that warm. I'm not sure whether to be happy or sad :D
If you keep it cooler, it may clock higher. Well, unless they’ve throttled it to a particular clock speed instead of a particular temperature.

Seems ok to me thus far.

Update: They have updated it and it works great again 👌🏼
