When the user filters the amount of items in the left list decreases. It would be nice, also as motivation to watch more session videos, to know how much videos are left in the left list, e.g. when I activated the unwatched filter.

FFMPEG supports a "video file name" of image-%04d.png, and moviepy accepts this in VideoFileClip() which is great. But unfortunately it assumes 25 fps, and I don't see any way to change that. I can call clip=clip.set_fps(24) but that doesn't change the duration - I think it just skips frames.

It would be great if VideoFileClip could accept an optional fps arg for this case.

~/.config/youtube-dlg should just contain configuration files and not logs (which should go to $XDG_DATA_HOME/youtube-dlg/ ) nor youtube-dl binary (which should go to $XDG_CACHE_HOME).

Please also consider using appdirs instead of hardcoding ~/.config/

It would be cool if it would remember settings I gave it, so I can have the same settings for multiple files (or even support multi file processing). ATM I need to remember which settings I have set and it is hard to adjust width/height to exactly that dimensions as before.
