DashIsoSegmentLengthControl
Specify how you want MediaConvert to determine segment lengths in this output group. To use the exact value that you specify under Segment length: Choose Exact. Note that this might result in additional I-frames in the output GOP. To create segment lengths that are a multiple of the GOP: Choose Multiple of GOP. MediaConvert will round up the segment lengths to match the next GOP boundary. To have MediaConvert automatically determine a segment duration that is a multiple of both the audio packets and the frame rates: Choose Match. When you do, also specify a target segment duration under Segment length. This is useful for some ad-insertion or segment replacement workflows. Note that Match has the following requirements: - Output containers: Include at least one video output and at least one audio output. Audio-only outputs are not supported. - Output frame rate: Follow source is not supported. - Multiple output frame rates: When you specify multiple outputs, we recommend they share a similar frame rate (as in X/3, X/2, X, or 2X). For example: 5, 15, 30 and 60. Or: 25 and 50. (Outputs must share an integer multiple.) - Output audio codec: Specify Advanced Audio Coding (AAC). - Output sample rate: Choose 48kHz.
