Catchin’ SYNC operation notes

Catchin’ Sync is a utility that helps you determine the amount of synchronization error between video and audio signals in your
 playback system. A sample video is included with this app for you to see how the technique works. Purchasing the full access allows 
you to record or use your own videos.

About the “Measurement Frame Rate” parameter: This setting has no effect on the frame rate of the test recording. Catchin’ Sync will always record at the highest frame rate available (240fps on iphone 6, 6s, 7)

“Measurement Frame Rate” refers to the frame rate of the material you are testing. To enable this option, change “Offset measurement unit” from the default “milliseconds” to “frames per second”.

HOW TO USE:

1- Select a video file to play on your system that has clear sync points. Best examples would be frame-long countdowns, or pips
(pops). Anything with a clear visual reference and a sharp sound should work fine. Make sure that the visual reference exists somewhere in the middle of the screen. (visit our Downloads page for videos you can use)
2- Play this portion of the video on your screen for about 5-10 seconds and record it with Catchin’ Sync (only if you have purchased full 
access). Do this with the sound turned up higher than usual and no other noise interference.
3- Find an appropriate visual sync moment on the recorded video by using the thumbnail strip above the video, and then frame by
frame by swiping the main video window gently. You can do frame by frame adjustments with on screen buttons as well.
4-While the video is parked at the desired frame, touch the lock button to unlock the audio layer so you can move the waveform back and forth independently of the visuals. Slide the waveform with your fingertip to line up the audio event with the red line.
At this point, the offset amount will be displayed in milliseconds by default. Make sure to compensate for your device’s offset amount as well as other settings in the settings tab. Find listed device offsets on Devices page.
♦ Sample recording that is supplied with the demo is of a 25fps video playback off a TV screen.
♦ If possible, perform the above steps on multiple points on the video to achieve better accuracy.
♦ Positive offset value means audio is advancing the video on your system.
♦ Negative offset value means audio is delayed.
♦ Shake your device to reset the calculation.
♦ Compensate for distance if you’re far from the sound source.
♦ You can also measure approximate distance of distant events like lightning, fireworks, flare gun etc.
