TimecodeSource
Use Source to set how timecodes are handled within this job. To make sure that your video, audio, captions, and markers are synchronized and that time-based features, such as image inserter, work correctly, choose the Timecode source option that matches your assets. All timecodes are in a 24-hour format with frame number (HH:MM:SS:FF). * Embedded - Use the timecode that is in the input video. If no embedded timecode is in the source, the service will use Start at 0 instead. * Start at 0 - Set the timecode of the initial frame to 00:00:00:00. * Specified Start - Set the timecode of the initial frame to a value other than zero. You use Start timecode to provide this value.
