How sync works
Every source in a session runs on one shared clock. Phones and microphones are then lined up by their sound: a single clap reaches all of them, and LansPilot finds it in each waveform.
Webcams and the screen have no microphone of their own in the session, so they follow the shared clock.
This is a check before you record. The final sync is still computed after the take.
Before you start
- Connect the phones and open Prep on the computer.
- Put the phones where they will film. Moving them later is fine; the clock goes with them.
- Keep the room quiet for a second so the clap stands out.
Run the clap check
- Open Sync check in the Setup tab. It starts listening on every phone.
- Press Clap check, wait for Clap once, now, and clap once, close to the phones.
- When two or more sources hear it, the lanes slide into line and the chip says Locked.
Read the lanes
The number at the end of each lane is how far that source was from the reference before it was corrected. A dashed lane follows the shared clock and needs no clap.
Turn on Keep checking while recording if you want the lanes to stay live during the take.
If a phone won't lock
No clap heard means the clap was too quiet for that phone. Try again, closer to it. Limited precision on this phone means the phone can't say exactly when its audio was captured; it still syncs after the take.
