Thank you for the response, much appreciated!

Also, I play console only; I do not play emulators. So a simple laptop screen record would not be useful.

Look guys, I understand that real time video capturing software is pretty easy to get for most of you. But I am poor, 40 years old, and don't really understand this technology anyway. So can I just record my run on my phone and submit that? I just wanna run Quake II Expert Mode on N64, a category that literally nobody has submitted a run for, so I don't think cheating should be a concern.
