ffmpeg -f avfoundation -i 1:0 -af volume=1 output.mkv

I'm using Usb-C to DisplayPort cable and native resolution 3440x1440 looks too bad...
image is crisp in comparsion with Windows 11 on the same monitor
https://monosnap.com/file/nvFvXSevMs64idO1bK6zq1362LSZ9c
1720x720 HiDPI is making image much better, but UI is too large in this case
how can I get something between 3440x1440 and 1720x720
Want to see solutions from another owners of 3440x1440 monitors

I am trying to get started using this FFmpeg "complete, cross-platform solution".
The home page has a line of code that says:
$ ffmpeg -i input.mp4 output.avi
When I plug this code into my command prompt, I get the following message:
'$' is not recognized as an internal or external command,
operable program or batch file.
What you are doing wrong is to copying the '$' as part of the command.
ffmpeg -i input.mp4 output.avi
would do the trick.

I was wondering how can I use ffmpeg.dmg on Mac same way as ffmpeg.exe on windows via bat files? without installing ffmpeg on the PC.
For example if I wanted to create a thumbnial from video file I type this line in a text file and rename it to xxxx.bat and place it beside the exe
ffmpeg.exe -i "input.mp4" -an -ss 00:00:02 -an -r 1 -vframes 1 -s 512x512 -y "output.jpg"
anyway to do the same on mac? I tried renaming ffmpeg.exe to ffmpeg.dmg and xxxx.bat to xxxx.command thought it was that simple :) but of course didn't work.
You can download compiled binaries of ffmpeg for Mac as well here.
For the batch-thingy you can find more information over here as it needs more than typing and a double click in Mac appearentely.
