Issue with mime type

[aaa3334]

Hi!

I am testing using this over using eg remotion. Right now I have remotion up and running.

I am testing with eg this video here: https://videos.pexels.com/video-files/6763418/6763418-hd_720_1280_25fps.mp4

My issue right now is that in remotion it works but here I get: null is not an accepted mime type

I am unsure what the platform is reading it from, but it would be good if we can set the mimetype ourself or override it - I had a little look a the code but couldn't figure out how to do that besides overriding the actual back end code (no input seems to be available unless I have missed it?)

Thanks in advance!
