Time lapse

I’m looking to capture a time-lapse of a theatre show being set up (full get-in/build, ideally from empty stage to show-ready), and was hoping for some advice from people who’ve done similar.

A few things I’m trying to figure out:

Apps/software – Are there any good apps for managing long-duration time-lapses? (Preferably something reliable over several hours or even days) Camera choice – Is a DSLR/mirrorless essential, or can a phone handle this well enough now? Power setup – How do you keep everything running for long periods? (Mains power vs battery packs, etc.) Mounting/positioning – Any tips for keeping the camera stable and out of the way in a busy theatre environment? Interval settings – What kind of interval works best for something like a set build?

Also, if there are any common mistakes or things you wish you’d known before doing your first time-lapse, I’d love to hear them!
