Thread: Audio and Video Sync

  1. #1

    Audio and Video Sync

    PROBLEM DESCRIPTION

    SDI output from a camera can include embedded audio. When captured this way there is little reason to worry about sync between the audio and video.
    However if a separate analog option is used (such as XLR) from the same camera then sync issues can occur. This is because the audio is coming straight out of the camera and into the recording system while the video from the same camera still needs to be processed by the camera before being output. The effect of this delay will be indicated by the audio leading the video sometimes by several frames.

    Be mindful of this in situations where there appears to be a sync issue. Check the configuration being used and act accordingly.
