Description

This element will drop all buffers until a specific timecode or running time has been reached. It will then pass-through both audio and video, starting from that specific timecode or running time, making sure that audio starts as early as possible after the video (or at the same time as the video). In the "audio-after-video" mode, it only drops audio buffers until video has started.
