Since I’m considering speedrunning some mobile game which could take over 1,5 hours, there might be an issue while recording. My phone has a max file size limit of 4 GB. Obviously, the screen recording app recording size limit can be set to the max possible limit which depends on the device (in this case it’d be 4 GB). As I’ve noticed, 4 GB is around 1 hour and 20 minutes of a recording. That means the rest of such a speedrun would be in a separate file. Tl;dr one file would be the first part of the recording lasting for 1 hour and 20 minutes and another one would last for around 20-30 minutes. Let’s say I’m uploading both these videos on YT. And I’d like to give links to both parts in a run submission. Would I be allowed to do that or would such a run be rejected? If the second option is the case, then should I consider live-streaming that attempt?

So typically for mobile games, experienced mobile moderators will say that a run longer than 1 hour may be completed in separate video segments, but must be completed in one sitting. I would check with the mods to make sure, but most mobile runners know of this limitation.

Firstly, I'd say to join the Mobile Speedrunning Discord so you can talk to several mobile mods and get various opinions :D

Secondly, I'd say it depends on which game you are playing and who the active moderators are of that specific game. They might have different rules.

I mod several mobile games and my opinion doesn't match what @VyPr suggests. If it were one of the games I mod, I'd ask you to stream on your phone using YouTube or Twitch in order to get a complete one-segment video of the run online. That's the solution I've used for various games that take longer than an hour to record :))

Best case scenerio, yes, stream your attempts; however this isnt really an option for older devices. For example, my old google pixel would get really hot and crash after 30 mins when i would stream, so be mindful of your hardware limitations. Alternatively, which will probably work in your case, is to record at 30fps in 360p (or 240p). It will look like a potato but hey, at least its in one segment.

If you want decent quality for youtube, split segments is usually your best bet, but do be mindful of rules. It sounds like if your max is 4gb recording, then storage is 16gb? There are many workarounds, just see what works for your device, especially if it is old.

Thank y'all for your suggestions. I browsed the Internet in search for how to livestream a mobile game. The problem with livestreaming on YT is that you apparently need at least 1k subscribers in order to even be eligible for doing it. I believe there is some external app with which you can livestream your content on YT, but I'm not sure whether it could bypass YT's requirements. And I'm not really feeling like signing up at Twitch. Sure, I wouldn't have sponsors since I'm speedrunning just for fun and I'd rather earn money with a normal job, but I'm just not sure about the platform's future. So in case of a livestream, that might be a bit problematic.

I also reached out to the game mod yesterday evening and as they claimed, as long as there is no missing gameplay between the 2 recordings, it'd be fine to do that in a way I explained at the beginning. Speaking of the quality, I believe that even if I set up 720p as the recording quality, in a longer recording YT seems to process my videos just in the 360p quality (unless I'm recording on iOS since for some reason I can't just change the recording quality on iOS). But anyway, since I got in touch with the game moderator and they gave their opinion on that, I take their words for granted.

Actually, my current device has a storage of 64 GB, yet the max file size is just 4 GB for some reason. On my previous phone the max file size was 2,5 GB whereas its storage was 16 GB. Pretty weird, if you ask me, but there's nothing I can do with that. But that's alright as long as the run gets accepted in the form of the segments of the run done in one sitting.
