Here’s a list of known average device offsets. We recommend doing this test each time there is a major IOS update. After you line up the sync point, the lag value will be on screen.Įnter the opposite value in your settings tab as the offset value (i.e if the reading is -13, enter +13 in the settings as offset). Please make sure the device offset is set at 0 in settings (and the offset measurement unit is in milliseconds) before you record. Anything that makes an instantaneous sound with a clear peak and clear visuals will work. A marble or a golf ball bouncing on the desk is also a great option. If you don't have access to a clapper board, use a binder clip or a clothes peg and squeeze and let go for the snap. Using Catchin' Sync, record something that makes a snap, like a clapper board. There is a simple test you can perform yourself and set your device offset. Catchin' Sync lets you compensate for this offset amount so your measurements are accurate. So, if your audio and video are out of sync, Catchin' Sync will help you synchronize them!Ĭatchin' Sync Device Offset Test ProcedureĮach device and IOS combo will have a slight variation in how much offset there is between the recorded audio and video at high frame rates. For home users, most Receivers and TVs, Apple TV and even VLC will let you enter this information. Most video hardware interfaces like Blackmagic and AJA will also have settings to do this. You can use the offset information in your editing software (AVID Media Composer, Adobe Premiere, Pro Tools, Nuendo, Studio One, Blackmagic Resolve, Final Cut X etc.) and compensate. With that information you can add appropriate amounts of delay to your signal, and get everything play along properly in SYNC. Catchin' SYNC will help you determine if your system is in SYNC or has a lag and by how much in milliseconds or frames. In almost all cases, where audio and video playback passes through separate devices (i.e Audio through receiver, video through LCD TV or Projector etc.) there will be advancement or delay on the audio signal, making the viewing experience unpleasant. Catchin' SYNC allows you to capture and manually determine audio SYNC issues of your video playback device.
