Video transcoding slow with M1 Mini

I transcoded the video from a DVD with Handbrake, and it took dramatically longer than it does with my 2010 iMac.
:S I did notice that that Handbrake was set up for 2 pass encoding on the Mini. Should I uncheck that option?

Are you working with metric or Imperial bits and bytes?

You can make Handbrake go as fast or slow as you want, it's all in the settings.
It's generally speedier to transcode using the single pass RF function as opposed to 2-pass. I only use 2-pass (Turbo 1st pass) when the original file is very noisy as the RF method doesn't care about ending file size, only end quality, and thus tries so encode all that noise making a giant file. I use rf17 h.265 slow settings but that's for permanent addition to the video server and I use a high end 8-core CPU to do the conversion. Try out rf20 h.265 medium (or h.264 if you need that) and you should get decent speed. Also look in the Filters section and turn off all the deinterlacing and decombing stuff if you're starting with a clean progressive file, that'll cut down some processing time, too

I guess I need to contrast and compare the settings between the machines.
Thanks

If you are running an older version than 1.4, it will use Rosetta2 and that may slow it down a bit. https://handbrake.fr/downloads.php If you see the option in the Video settings to choose the "Video Toolbox" Video Encoder, try that one. It should speed things up dramatically.

Oh - Okay, I just downloaded a "universal" app.
I try this again and see if it's any faster. |
