(First post here, please at least tell me where to post this in case it violates rules) I have a question regarding Riot Support and reporting a player through it (game is Valorant)

(this is some context, question is down below) I recently had a player on my team throw the game and went to the support site to report him. However, I could not attach a video file. This has been the case with multiple reports I have attempted to do. The error is primarily that it took too long. I compressed file down to 480 p and cut out some parts of it using Microsoft Clipchamp (free version), reducing file size to around 34 mb (clip was around one minute long give or take). However, I still could not upload it. So I attached a medal tv link to the clip in the description.

My question is, what file size should I keep the uploads at and if I should use medal tv uploads in the future, and if I should attach the link in the description.
