I had an average of 166fps converting to h.264 (super high quality preset/x264 software encoder) at 720p. I converted 80 large files and I did not notice any noise, heat, or slowdowns.

I've seen reports that the intel hardware encoder (Quick Sync) produces better results than Apple's. :confused:

I'd be really interested to see these reports. Quick Sync is ok, not that great, the problem is on macOS, VideoToolbox doesnt allow constant quality as a method of encoding, just bitrate, so files tend to be much bigger, or much worse quality! I can't imagine Apple's encoder would be worse, given the iPhone's video recording quality, but time will tell I guess.

On pre T2 Macs, VideoToolbox uses Intel QSV as the underlying encoder for VideoToolBox. VideoToolBox does have a "quality" parameter, but the definition of the quality is different from cq. It's a number ranged from 0 to 1, where 1.0 is lossless.

"Quality" parameter does not work on Intel QSV. In my testing you can put any value in it and the result will always be the same on Intel.

What preset would you recommend for 720p (1080p) videos with 29.98fps for best quality and best smaller size possible? I want to shrink my tv series collection a lot.

I've dumped the supported encoder information on M1, and I found some pretty interesting thing.
It seems like M1 does support HEVC_Main10 even at 444, and handbrake is not using that now.

DVDFab appears to be much more optimized. Does DVDFab do h.265. I will certainly check out DVDFab over the weekend. I have optimised many videos for my office before uploading on Youtube or when we have to share certain technical video presentations with our industry partners.

It does H265 yes, even toolbox. Great application.

DVDFab uses the same exact decoders/encoders. In HandBrake make sure to disable the interlace detection and demob filter. It's enabled by default in almost every preset. The only difference is which settings you use.

Yup HandBrake does not yet. Patches are welcome. I don't have much time right now to work on HandBrake. ;)

I've done some testing (for capability) myself using ffmpeg.
HEVC Main10 is accepted by the hw encoder, but the output video is always 8bit, looks like some "silent fallback" occurred, not sure if that's ffmpeg's implementation or the hw encoder's design, if I add -require_sw 1 to use the software VideoToolBox encoder, it does output a 10-bit video.

The 444 pixel format is not handled now in ffmpeg's VideoToolBox implementation currently, I cannot test that with ffmpeg.

Test is done by using the Jellyfish Video Bitrate Test Files, particularly jellyfish-120-mbps-4k-uhd-hevc-10bit.mkv

Anything else you guys want me to encode/copy/compress/ etc for speed comparison? Only my Mac Mini 6-core for now

The 10bit HEVC hardware encoder works. FFmpeg has got a improper check that needs to be removed:

The 10bit encoder requires the AV_PIX_FMT_P010LE pixel format.

Could that be incorrect handling of ffmpeg as well? Because I noticed that ffmpeg did not include 10 bit pixel formats other than P010LE in hevc_pix_fmts of videotoolbox:
Code: 
static const enum AVPixelFormat hevc_pix_fmts[] = {
    AV_PIX_FMT_VIDEOTOOLBOX,
    AV_PIX_FMT_NV12,
    AV_PIX_FMT_YUV420P,
    AV_PIX_FMT_P010LE,
    AV_PIX_FMT_NONE
};

I have ffmpeg working on my M1 MacBook Air. It took a combination of MacPorts for most of the requirements, downloading ffmpeg from git and building libx264 from git. The libx265 library worked from MacPorts but libx264 didn't.

VideoToolbox is supported. I don't like VideoToolbox, because of lesser quality (it's fast as blazes, though). If you intend to use VideoToolbox and you already own an Intel Mac with T2 coprocessor, you don't need to upgrade your machine just for Handbrake purposes. There will be zero or negligible difference.

If you're encoding without VideoToolbox, Handbrake 1.4 beta allows the M1 13" MacBook Pro to perform CPU-driven HEVC encodes approximately twice as fast as the 2020 i5 13" MacBook Pro — i.e., on par with or faster than the 16" i9 MacBook Pro. Yikes!

If the rumors about M1X are true, and it will be 70-80% faster than M1, the upcoming 16" MacBook Pro refresh said to be with M1X will make it a no brainer to buy.

Screen dumps I've seen (I think in this thread) indicate the M1 VideoToolBox API has a Constant Quality knob that the T2 enabled Intels do not have.

currently I've tested Wondershare Ultimate Converter on my M1 compared to my iMac Pro 8 Core - Vega 56 and the MacBook M1 seems as fast my iMac, insane.

But I don't know if its a native App so far.

What other Video Converter would you recommend? I need to make a batch of 30 4K Videos to 1080p, does Handbrake support Batch converting and how is the quality?

Have you tried DVDFab?

You can look in the activity monitor. It will say either application type apple or intel.
