Help with Highlights Workflow: 2 Synced iPhones + Buffer Recording + ActionStitch

Hi everyone, glad to have found this forum!

I am validating a business model focused on selling sports highlights, and I need help structuring the MVP for my capture setup. Since recording the entire game is unfeasible (due to storage and editing time), my goal is to record only the relevant events.

The scenario I am trying to implement:

  • Hardware: 2 iPhones covering the court using ultra-wide lenses.
  • Recording: Circular Buffer (Retroactive) – when the trigger is pressed, it saves the last few seconds (the play).
  • Sync: I need the trigger on one device to simultaneously activate the recording on the other.
  • Post-Processing: Stitching the two angles to create a panoramic view, and subsequently manually reframing to vertical (9:16), but strictly for the necessary clips (since many plays develop entirely on just one side of the court).

The problem: I cannot find a tool that combines Buffer and Sync.

  • Fullcourt: Syncs devices, but records the whole game.
  • Video Buffer Camera 4K / MyMVP: Record in buffer mode, but do not sync two devices together.

Does anyone know of a solution that bridges this gap?

Extra question about ActionStitch: Does anyone here use ActionStitch with iPhones? I would like to know if anyone has a step-by-step guide on how to optimize capture with it on iOS.

Thanks in advance!
