I don’t have a capture card so can I use the Nintendo switch to save each 30second clip then put them together for proof of an il run

@Haseeb_Gaming if is proved that is all together it should be nice, but any run like that can be segmented, so thats hard to do, and you have to record for every 30 seconds in a constant way In all case, probably the mods will not allow it

you can submit runs using your phone as a camera.

a capture card is not required but a continuous recording is required

For my runs, although they are not the best quality, I use my phone in all of them.

I recorded it but u can only see 2 thirds Of the screen do u think that will be fine

Probably not, I would re-record and capture the entire screen as best as you can.

Would u say this is good enough

No, perhaps undocking the Switch and putting your camera I front of it with the timer behind it. That is what I do.
