video compression crops the videos to 16:9 aspect ratio

### Steps to reproduce

1. take any video that is.. 1:1 aspect ratio? Not sure what triggers it exactly, I have supplied a video.
2. it'll crop it to 16:9 aspect ratio when uploading, which loses all of the content above and below

If the video is more vertical, it doesn't happen.. but it seems it doesn't like 1:1

not compressed raw video:
video that ran through element's compression:

this is also unrelated to H.264 or mp4, as it does it with vp8 and webm as well

### Outcome

#### What did you expect?
not to lose the data of the video
#### What happened instead?
lost data
