I would say not until you get a good time, but I'm not an authority.

Video link is a required field when submitting your run. I have the same problem as you, I love speedrunning this game but I currently have no capture card so I can't record it, and thus I can't submit my times.

Do you have just a camera? That should work. You can also use the YouTube Capture app if you have a mobile device.

I use a fuckin I pad #strugglelyfe
