Hey , i just want to know if i can film with my phone and upload this on yt ? And after give the url on Speedrun site . Sorry for my bad english , i try my best 😅

As long as the video and audio come in clear, should be fine for the most part. Would probably want to double check with the moderators of the games you are running first since some may not allow it or would require a capture card when you reach certain time goals. If you're running on emulators though, you can just get OBS to record for free.

Ok thanks 👍🏻
