Sync Sound
Sync sound is audio recorded simultaneously with the picture and meant to stay locked to it.
What this is about
Most productions shoot dual-system: the camera records picture, a dedicated recorder captures sound, and the two are married in post. The link is the slate clap or shared timecode — both give the editor a reference to align by. Once synced, every take carries its dialogue as shot, which is the foundation the whole post workflow builds on. Single-system shooting, with audio going straight into the camera, trades quality and flexibility for simplicity.
A term only helps when everyone on set means the same thing by it — so what follows is how it is used, not a dictionary definition.
What runs differently here
In planning terms, that means:
- Dual-system needs a sync reference on every take — clap, timecode, or both
- Camera scratch audio helps auto-sync software even when it never reaches the mix
- Confirm sample rates match across recorders before day one
With TillyGen
TillyGen's schedule marks which scenes carry sync dialogue and which are MOS, so the sound crew's day is planned around the takes that matter.
Change one constraint and the consequences travel through the whole plan: affected shots are flagged, the call sheet is regenerated, and nobody keeps working from yesterday's version.
Frequently asked
Why record sound separately instead of in the camera?
Dedicated recorders offer better preamps, more tracks, and independent control. Camera audio still gets recorded as a scratch track for syncing.
How long does it take to get started with TillyGen?
A first project takes under an hour to set up. There is no configuration phase in which templates and fields have to be defined before the tool produces anything.
Can the results be exported?
Yes — as PDF for the crew, CSV for downstream systems and through the API for anything automated. The plan stays the source; the exports are views of it.
