Description
Hello.
Firstly, I have to say that I really appreciate all the amazing work development team is doing. There is a lot of effort and hard work behind this astonishing project. However, there seems to be a huge issue with compression of video files from iPhone photo library. Quality of video after compression is really bad. I can barely read the text when a friend send me screen recording from his iPhone. After doing some research on the internet, this issue seems to be here for a while. As far as I know, the huge loss in quality only happens on IOS, when the MOV video file is being converted to mp4 file. When I recieve a video sent from an android phone, quality seems just fine.
