Use this setting if your input has video and audio durations that don't align, and your output or player has
strict alignment requirements. Examples: Input audio track has a delayed start. Input video track ends before
audio ends. When you set Pad video to Black, MediaConvert generates black video frames so that output video and
audio durations match. Black video frames are added at the beginning or end, depending on your input. To keep the
default behavior and not generate black video, set Pad video to Disabled or leave blank.
