Poor Editing Performance on New M1 Mac Studio

I just set up Premiere on a clean M1 Mac Studio.

Editing lightly-compressed h.264 footage in a timline lags 3-5 seconds scrubbing and hitting play.

Here is a video of clicking around the timeline in Premire Pro showing a significan lag

Here is me skipping around inside the same video on the same M1 Mac, this time in QuickTime Player. Skipping through the file to access random frames is instantaneous:

Here I am skipping around the same file in KDENlive on generic Linux hardware. Performance is also near-instantaneous:

Why is Adobe performance on the latest Mac harware inferior to free/Linux software on old hardware?

Will this be fixed soon?

Is this better on Wintel? I have 10 days to return my hardware purchase.

Holy smokes!

Can confirm this appears to be fixed in the Beta. So much better.

With the Beta version of Premiere, I'm seeing performance much more in line with what I expected.

Thanks for the tip!

I just setup a brand new M1 Ultra Mac Studio running OS 12.5 with Premiere Pro 22.6.2 and I'm getting laggy playback performance. Footage is 4k h.265 10bit 420 from Sony A7siii. 2 layers of footage with a simple title. Running off of a Crucial 4TB SSD connected via USB-C on the back of the Mac Studio with one of the Thunderbolt 4 ports. Pretty frustrating that it's lagging considering that on my 2018 PC with a GTX 1080 and I9 processor with the same footage using a spinning HDD with USB3, it doesn't lag. There is obviously an issue with Premiere Pro not tapping into the power of the M1 Ultra chip.... I do not want to transcade to ProRes. I spent the extra money and upgraded to the top of the line Mac to avoid spending the time making proxies or transcoding. This is a light edit I'm doing, and as mentioned, something like this works fine on my PC. When will Premiere put stability and performance first? I can guarantee you if I drop this exact same footage in DaVinci, it'll run like butter.

Running multiple tracks of long-GOP 4k 10 bit is by no means "light" editing. Long-GOP media is the nastiest crap for editing made, period. Amazing for data compression and speed when used with the specialized in-camera chips. Lousy for playback in an editor.

Remember, for both those tracks, your machine has to decode up to 30 frames or more to display the 'current' frame on the timeline.

A couple tracks of 6k RED would probably be easier on the machine.

H.264/5 work depends heavily on the inherent capabilities of the underlying hardware to process the specific forms of H.264/5 compression you are working with. I don't know the particulars like say @RjL190365 does, but I know enough that the hardware matters. And is often not what one expects.

And some people get better results when they turn on the prefs for H.264/5 encoding and decoding, some better when they turn them off. Why? I don't have a clue.

So if you haven't messed with the prefs for H.264/5, try that. And we'll see if someone can give a tech description based on the specific hardware you're running.

The beta hasn't been released because it's the 2023 version ... I would guess it's going to "drop" on the first day of Adobe MAX which has been their practice four years now. Next major version has been dropping between 12:05 and 7:30am Pacific time that first morning of MAX.

And you can always try the public beta, I recommend people actually have that alongside the current version. And of course, keep the previous versions installed also.

Normally, the public beta is pretty solid really ... occasionally you'll get a bad build but not often. I worked last year for several months straight in the public beta without a hitch.

Not sure why you would transcode to prores when you could more simply make easy-to-use proxies which is what I have been using on my old cMP. (Once an edit is finalised in proxy version, the switching back to the original codec/format is fine.) Catalyst also costs another couple hundred a year.

The point is to avoid all this. I know Mac Studios work seamlessly in Davince and FCP with the same codecs as I am back to editing some projects in Davinci.

I see Max is pretty soon, 18 Oct.

My question stands re preferences for H.264/5 and their location? Is this in Premiere or Apple pref?

Sincere thanks!
