When I look through the leaderboards, almost every single video is from twitch, which to my understanding means it was streamed and not uploaded. I've got very fast fiber internet, yet even when I run theres still a chance that my stream will cut out for 5-10 seconds during an 1.5 run and my run gets invalidated.
Are most people streaming AND recording in case of problems?
I don't usually record, I stream and just hope it goes fine. Not sure about others though
If you can, you should definitely local record while streaming. Shit happens, and you don't want your PB run to be rejected because your internet cut out.
I always locally record and stream at the same time. Highlighting the Twitch VOD and then exporting it to YouTube is a lot more convenient than editing and uploading it from a local file, but I've had enough problems with Twitch and my internet to not completely rely on that.
In OBS if you record at the same settings/quality as your stream then there's basically no performance overhead as far as I can tell, so as long as you have the storage space for it there's pretty much no reason not to.
I was just worried about storage space filling up quickly with a 1.5 hour run, but I’ll give it a shot tonight
I stream at 800kbits due to my internet getting less reliable all the time (I'm really hoping for an upgrade soon...), so I started local recording quite a while ago. For quality options CQP 18 seems to be the way to go, as it adjusts bitrate variably depending on content. A Fullscreen GBA game would be only 400kbits and still look 99% lossless, while something a bit more complex will take the bitrate it needs to look near-lossless as well. I used to just do 4000kbits, but now my local recordings are usually a lot smaller, but look way better and even after re-rendering in Sony Vegas (with higher cpu preset and either 2000 or 4000kbits depending on what the source file has on average) the difference between twitch stream and youtube re-upload is definitely worth the extra trouble for me.
I used to, but I'm a beggar for forgetting to hit the record button so I just rely on Twitch's feature to record old broadcasts. I'm always in fear of the stream not staying saved, but that seems less likely than me forgetting to record. You could do both to be fair, there's no reason not to and it's doubly sure. it just kills your HDD space unless you delete it all again after you've finished.
