An alternative cure for Lip Sync errors!
The “SmartLips Pack” contains a co-timed Flash and Blip generator that can be used to check for lip sync errors, especially in conjunction with the SmartLips combined Photometer, Sound meter and off-screen A/V sync meter. Additionally, the set contains a Test Signal DVD set. See the pdf (below) for more details.
Use the generator to record a few seconds (or establish a live feed) of video/audio from a measured distance, then use the Smartlips meter in the post production suite or control room to measure the time phase between each audio and video flash and blip instance. The simple meter display will tell you the phase (lead or lag) in ms, allowing fixed audio delays to be implemented per a given workflow, to ensure consistency. This can even be used to check differential video throughput latency between monitors - a critical unknown.
