in addition to show the results at the top of each laptop I'd appreciate if you add a summary chart at the end, nothing fancy, it just that way we can just pause the video there instead of going back and forward if we want to know what the first machine result was. Love your content and I'm really appreciate it. Regards from DR

[@kaxopubg]

Which will result in people skipping to the end and just looking at the chart which has the results as you mentioned it would be great but then he will be at loss (Alex Ziskind). Regards Hamdan Khan

[@richarddcrossley]

I’m from the U.K. and up and up means things are going in the right direction in your life or in general. Not sure in this use case I’d use it 😁

[@haploguy]

For the software encoding test it'd be useful to use a version of ffmpeg compiled with the cpu NEON extensions which the Mx arch has but most likely are not used.

[@Billy123bobzzz]

Thank you! That was an excellent test that really helps us because we really wanted to know the difference while using FFMPG so we can pick the correct machine for our needs, well done! Keep up the great work!

[@AZisk]

Glad it was helpful!

[@ScottLahteine]

One place where I use ffmpeg pretty frequently is to produce a video from the output of Gource, which makes a cool animation out of your git commit history. That's done by piping the output of gource directly to ffmpeg, and it can really take a while if your git history is very long.

[@MrDob2009]

Thank you very much for these tests!!!

[@AZisk]

No problem!

[@frankwales]

A potentially interesting further stress test would be to take the script that generates all the different resolutions sequentially and change it to run all the ffmpeg commands simultaneously; put '&' on the end of every command, and add 'wait' to the end of the script, and all the ffmpegs will run concurrently, with the script not exiting until the last one finishes. If anything is going to soak up all available capacity, and drive the temperature up, it'll be something like this.

[@AZisk]

yes this would be good too, and would really get pretty hot

[@toadlguy]

ffmpeg will use all the available resources by default, so I don’t think that would actually change the results, but you could try it.

[@frankwales]

@@toadlguy I was thinking more 'stress test' than 'faster encoding', since several CPU/GPU saturating tasks that also do a bunch of I/O might tell you something about thermal handling, process handling or file system efficiency. (But then, I like hammering systems with unreasonable loads until they break, so I can get a sense of where their limits are.)

[@livendi3229]

Appreciate the content

[@ayushs_2k4]

Please include the M1 Pro base configuration also, if possible

[@Fuzzi974]

Those tests, the 4 machines against each other, I always like to see them. I can't wait for M3s to get out (if Apple keeps this way of naming them) and see more tests.

[@jaycarter592]

we say that "everything is on the up and up" in Guyana

[@AZisk]

Nice !

[@richarddcrossley]

Funny as years ago I was looking for an easy method to test energy usage and temperatures under sustained load and measure the results. I’m not a coder so settled on handbrake in Linux using a tool that I could measure the results using Intel RAPL and output to a graph as it basically uses loads of resources at once. Geekbench was no good because it isn’t sustained load and now after following your channel for ages this pops up 😂

[@AZisk]

Seems like this oughta do it :)

[@remigoldbach9608]

I missed the Schwarzenegger. I suppose he had not enough fingers. 😬 Great video as always !

[@AZisk]

Oh he is in this video - and he's got N number of fingers via finger modules. I might not have enough space on my desk though.

[@remigoldbach9608]

Haha, i didn’t watch enough of the video before commenting ! Great to see him !

[@remigoldbach9608]

You got me 😁

[@AZisk]

Sometimes he shows up at the end :) You'll just have to watch all the videos to the very end now :)

[@remigoldbach9608]

Lesson learned for the next time : watch until end before commenting 😃 You are really entertaining, it’s pleasant to watch your tests !

[@mahonar]

Great work Alex. Im curious about x86 performance in current Intel/Amd generation against Apple silicon.

[@AZisk]

Thanks! Haven't tried the new 13th Gen Intel yet, but that's coming. I did do 12th Gen tests (linked in description).

[@mabbah4396]

Having a hard time to choose between m2 air of pro for music production...

[@mgjansen777]

Thanks very much enjoy every video

[@AZisk]

Thanks !

[@DaveDFX]

The Max chips have 2 encoders. Non max chips have only 1. Tested apps like Handbrake, Shutter Encoder, Resolve, and those apps are 2x faster on max vs pro. Ultras have 4 encoders.

[@rahulray14700]

Can u please paste the command somewhere and give us the link ?

[@wiktor0985]

shouldn't m2 Max be like twice fast on hardware encoding? It have 2 hardware encoders inside

[@MichaelAuerswald]

those only kick in if you render two separate streams in parallel. it doesn't distribute a single task onto both encoders, afaik.

[@douglasmontgomery6315]

Why does hardware encoding typically produce larger files and lesser quality? i would have thought the opposite ??

[@jvnetsl]

I don't know why your channel doesn't have more views. These videos are really good.....

[@AZisk]

Thx!

[@l.bogdan1360]

Tried to convert a 4k x265 video to 1080p AV1 using ffmpeg with Handbrake and gave up 15 minutes later (software encoder m2 pro max with 32gb) :))) it was so slow. Maybe in the future, we will get some gpu support.

[@AZisk]

I haven't tried that combination. You have a nice machine there !

[@haploguy]

av1 is notoriously slow in encoding, par for the course. only intel gpus have hardware encoders for it. everything else in software is painfully slow

[@l.bogdan1360]

​@@haploguy yes and Nvidia the 4000 series afaik. Maybe future M3s or later will get hardware encoder, or a videotoolbox with acceleration :)

[@frankwales]

02:07 Random tip: ctrl-A jumps to the start of the command line much faster than using left-arrow to get there (*assuming you're using bash, zsh or similar)

[@AZisk]

I know this, but it’s not part of my muscle memory for some odd reason, so I end up using it randomly, and always when I’m not recording a demo :) which is annoying to people watching. 😂

[@frankwales]

@@AZisk I wasn't annoyed so much as wanting to help a little with routine efficiency, since I enjoy learning a new shortcut or time-saving trick, so I outrageously presume other people do, too.

[@mckengineer5727]

Yes, everything is on the up and up’ is a beautiful English expression, meaning ‘it’s all getting better’ so, whilst it’s an expression, I’m not sure your use was the right context. Still jolly good effort and chin up Alex 😂

[@ovimine7628]

First of all thank you for the incredible videos that you're making! Can you please create a video about running Android emulator/iOS simulator from a Windows 11 ARM running in Parallels on MacBook Pro M2? If you can create a MAUI project in Visual Studio and show us if it's possible to run it in Android Emulator and iOS Simulator that will be really great!

[@AZisk]

I may be doing some MAUI here shortly.

[@cnekanba]

What is name of the app you are using that shows temperatures of the cpu?

[@AZisk]

Temperature and fan control: www.tunabellysoftware.com/tgpro/index.php?fpr=alex

[@crearg8259]

Does the FFmpeg command use Apple’s videotoolbox for encoder/decoder?

[@AZisk]

that’s an option. I talk about that in the video

[@Mark_MKII]

I’m thinking working with a longer video would better show the performance differences. Something that might take 5+ minutes to process. Get those fans spinning! 😊

[@ST14_109]

You look exactly like my science teacher

[@WilliamShrek]

Oh my god!!! Next generation schwarzenegger!!!

[@WilliamShrek]

schwarzenegger: time command? Who invented this? 😡😡😡

[@davinfleming]

Awesome video. Could you upload and share the scripts please? I could use those. Thx

[@topticktom]

You pointed the finger towards me Alex at 00:03 Seconds 😅

[@AZisk]

Ha - didn't even notice that I flipped everyone off. Total accident, of course 😜

[@tsalVlog]

woot

[@oa_munich]

You could use Ansible instead of Schwarzenegger

[@AZisk]

Yes, but then Schwarzenegger will be very upset. And you don't want to make Schwarzenegger upset.

[@oa_munich]

@@AZisk would make a fun video though, Schwarzenegger vs IBM (as in RedHat Ansible)

[@DaveBatistaa]

my dream is a MacBook m1 :'( Brazil its so expansive

[@fahimanayet]

😶‍🌫

[@DigiDriftZone]

Most of those parameters are unnecessary and also use h.264 which isn’t a great test (why not h.265), I believe x.264 only uses the CPU, not GPU Ffmpeg is one of the only things that are terrible on Apple silicon, I went from 50fps down to 3fps going from a Q6600 Intel to m1.
