Planning on doing an any% run but don't have a capture card for my new2ds, how would you recommend I record this

I gotta use my phone's storage for work and stuff (and I'd rather not have to do the run in segments) so I was thinking it may be possible to just do the run on twitch and then clip it for you

Thanks! I've got a route that's an easy sub 8:40 with good enough rng
