Sorry if it has been already asked

I’m planning to do Any% NMS but 8hours (maybe mess I hope) is too long for me Can I save while doing it ?

I know I have to record it all but can I send 2 videos or do I have to make it only one ?

Thanks

You can split the upload in 2 videos if it's too long for youtube or something, but you have to do the entire run in one session. If you take a break and cut out the footage of it, your run will be rejected.
