This has been causing some glitches on Linux, and runs into a problem on Colab (since there is no display present). The purpose of using Tkinter was to query the (scaled) screen resolution when using the manual cropping feature. It is a nice feature to adapt to different scale resolutions, but it perhaps comes with a too large overhead. Therefore I will not use Tkinter, instead maximize the possible video size (shown as the cropping window) to 800x600px that should work with pretty much any display nowadays.
