Problems uploading video files

When I am trying to upload a video file (.webm vp8, 4,767kb, PRO account) the upload seems to get stuck. Even after half an hour the upload is not finished. Seemingly randomly, in rare cases an upload succeeds, although the upload of the same file shortly before was not successful. In other cases a corrupt file appears in the Library under "Recent Uploads". This happens with different files. The problems exists for weeks now. The problem is not my connection. My upstream is at 50Mbit/s. Browsers: Firefox 88.0 / Chrome  90.0.4430.93 Tried with addons deactivated. OS: Windows 10, most recent updates

In the past, I have found that it takes 40+ minutes/MB (which is ridiculous). The problem seems to be on Roll20's end as the file is converted.

I honestly think that webp's and webm's get screened specifically by them for copyright.  I've had a few "personal use" screenshots I took and made with my scanner that they pulled from my quota without any warning or explanation.  I then resave them as jpg's and nothing bad happens thereafter.  If its not a copyright thing or something like that, then they have got an issue of webp's and webm's going corrupt.  And if a dev actually cares, I have 4 stored maps in my battlemaps session that had this happen to it that is on my todo list to reupload as jpg's instead of webps.  They are direct scans of my dragon hoard adventure.  They show up as broken images, and before you ask if they failed to upload, I literally drew an entire dynamic lighting layer with the images working initially so they do upload.  Its something on their end killing the images.  

Someone on the subreddit had reported last year that they successfully uploaded a full-size, animated map. It was a 7MB webm animation. After many unsuccessful attempts, it successfully uploaded when they accidentally left the upload process up and running overnight.

This is more than slightly disappointing.Roll20 is not cheap.

It was an animated painting made by a small artist I support on Patreon.
