If a video is recorded from an iOS device with HDR enabled, when sending it to Telegram as a compressed video, the color balance is not correct, resulting in a greenish tint all over the video.
For instance, video "1" is recorded with HDR disabled and sent compressed via Telegram. Colors looks natural.
Video "2" is recorded with HDR enabled, and when the video is sent compressed via Telegram, it looks more green than it should be and the color balance is not correct.
Workaround
Disable HDR when recording a video with the native iOS Camera app.
Send the video as file.
Steps to reproduce
Record a video from the iOS camera with HDR enabled.
Send the video from the attachment menu on Telegram and enable compression.
Current result
The video is sent compressed but the color balance is not correct. The entire video looks too green.
Expected result
The video is sent with correct colors and looks the same as the original.
I don't think it's a bug in the normal sense, just the lack of ability to send anything but standard H.264 and maybe h.265 as compressed video. Nothing else. Since HDR videos are no special format, it just converts it to 720p h.264 and ignores anything special. So basically the fix for that "bug" would be to implement something like ffmpeg to handle pretty much any type of media.
