On a Lumia 525 (with an empty 64GB card), the recording and import both seem to be limited to a few minutes (240 seconds I believe). Why does that limit exist? It seems that there's no persistent in-memory state that's needed as the processing seems to only
focus on the current frames. So why can't it just record and place the resulting 4x file onto the SD card?
Having a timelapse of only a few minutes doesn't really provide practical uses; without being able to record for hours (or process a long-length video), this app is a fantastic and fun demonstration of technology wizardry, but no more.
