It works on desktop, and is the go-to extension for me for manipulating videos. However, the extension is also possible to install on Android, but once installed there, there's no way, as far as I can tell, to map any of the binding to normal phone touch control, so it's unusable on Android.

the only one that works everywhere, even on shady streaming sites

拯救了老视频高宽比不正确的问题! 感谢作者!

Great add-on and works perfectly. If the dev adds scroll wheel zooming and click and drag function, Video Transformer will become the perfect video add-on!

Got to learn and/or set shortcuts, but it's useful when other extensions fail

exactly what I was looking for! I can finally watch 360p and 240p youtube videos at the size they are meant the be watched

Simples e útil. Tenho um monitor ultrawide, então consigo ajustar conforme preferir apenas com o teclado numérico.
No redecanais também, para esconder o logo.

So far this is the best youtube video zoom in/out, rotate, stretch and move extension for Firefox as it has pretty convenient keyboard shortcuts, which work great in their default setting.
The only other minor suggestion/improvement would be to have youtube shortcut buttons, which other extensions also handle.

Hello!
Yes, he is right. The functions start working after Refresh the page - I have a browser Firefox + Win10x64

Perfect!

Excellent tool! Now I can watch 4:3 movies on full screen! Can pan and zoom like in best media player MPC-HC! Thank you very much!

MPC-HC commands, amazing!

The functionality is good, but it never works the first time a video is opened. The tab always has to be refreshed once before it starts working.

Very good incredibly handy when you want to zoom in on something. Even works on Netflix however obviously not meant for it, as resetting the video places the image in the bottom left corner leaving you with just the top right corner of the video visible.
