vdownloader insists on incorrect quality/.webm format

hello,

I love to use vdownloader, but it bugs me how once in a while (and for long periods of time) vdownloader doesn't work too well.

when i use the no convert option on some videos, vdownloader first chose 360p instead of the correct 480p quality, and now vdownloader wants me to download as .webm instead of .mp4.

I like to pick no convert because I expect it to be the best quality without me changing anything. and if i try to go to advanced > mp4 > 480p, the bitrate is pretty bad, so that's a no.

i tried this other downloader, keepvid, and when I opened the 480p video I wanted, it saved as 360p similar to vdownloader's problem, so I think youtube is to blame here or something?

can you please fix this?

this is one of the videos I try to save, with srt files for the captions (vdownloader is really helpful for doing this, but I'm pretty annoyed because I don't want to save in different formats and the wrong quality).

thank you,

Hussein
