iTorrent VS staxrip

You can download the app .ipa file here and install it. Since it is an unofficial app, you will have to "sideload" it to your device. There's tons of information on how to sideload apps to your iPhone on r/Sideloaded.

By sideloading iTorrent

Grab the ipa and install it via AltStore.

Once altstore is installed, installing iTorrent is pretty simple

You can download iTorrent from the developers Github account, here.

Yeah I'm trying to install iTorrent. Let me know if it works for you.

Its literally a feature of all the underlying encoders. And you can do it even with exotic ffmpeg/vapoursynth filter chains. So I can't imagine why.

TBH I would just recommend Staxrip if you are on Windows: https://github.com/staxrip/staxrip

There is a linux equivalent, I can't remember what its called.

Or maybe some av1an GUI for Mac/Linux. All of these things support a target file size with many more features.

Since ffmpeg CLI still makes me pull ny hair out, I am going to plug vapoursynth:

https://www.vapoursynth.com/

Its Pythonic video filters... But also so much more: https://vsdb.top/

And Staxrip, which makes such good use of ffmpeg, vapoursynth, and dozens of other encoders and tools that I reboot from linux to Windows just to use it: https://github.com/staxrip/staxrip

https://github.com/staxrip/staxrip GUI But av1 outdated a bit which could be replaced/rebuild https://github.com/m-ab-s/media-autobuild_suite

2-4: I use StaxRip to encode the video because it includes the QTGMC deinterlacer, which is from my research a very good deinterlacer that produces less artifacts in the video than other deinterlacers like the one included in HandBrake.

But I actually got through it and found a great solution for myself using StaxRip and an updated QSVEnc by Rigaya. Replace StaxRip's outdated QSVEnc with the updated Rigaya QSVEnc.
