M4S in het kort
M4S
Convert to M4S when packaging video for MPEG-DASH or CMAF delivery, where playback depends on many short media fragments rather than a single monolithic file.
It is the right target for adaptive streaming infrastructure, CDN-friendly segmented delivery, and modern VOD or live workflows built around fragmented ISO BMFF media.
