Sync-One2

User Manual

Sync-One2 is an easy to use hand held tool suitable for professional and amateur users to quickly and

easily analyse audio/visual synchronisation problems.

To obtain the best results the use of supplied test files is recommended. These files

consist of very brief flashes of light and sound beeps. As these flashes are brief and

intense they may be perceived as similar to stroboscopic lights. Accordingly persons

with photosensitive epilepsy or similar condition that can be triggered by flashing images

should take suitable precautions when using these test files and do so at their own risk.
