M4S at a glance
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.
3FR at a glance
3FR
Convert to 3FR when preserving original Hasselblad captures or handing files into a Hasselblad-oriented raw workflow.
It is useful for archive retention, color-critical processing, and studio pipelines that need untouched sensor data.
