01 How it works

Four steps from phones to a finished cut.

Keep scrolling — the steps move sideways

01/ 04

Open a URL.

Devices join from any phone or laptop browser. No App Store, no IPA, no APK — just a link on the LAN.

  • No install
  • iOS · Android · laptop
  • Camera · screen · mic
02/ 04

Arm & frame.

Every assigned camera streams live to your laptop over the LAN. Frame each angle in the grid before you commit to record.

  • Live LAN preview
  • Per-camera bitrate
  • Pre-flight checks
03/ 04

Record losslessly.

Every angle records copy-only — no re-encoding. Near-zero CPU on the laptop; the phones do the work.

  • Copy-only
  • Near-zero CPU
  • Per-angle masters
04/ 04

Cut in post.

Press 1–9 to mark the program take while you record. Export the edit as one MP4, or keep the per-angle masters.
