HEVC/H.265 at a glance
HEVC/H.265
Convert to HEVC when the target environment can decode H.265 and the goal is to reduce bitrate for 4K, HDR, or long-form high-resolution video without giving up too much quality.
It is a strong target for premium streaming, UHD masters, efficient device delivery, and storage-sensitive archives that prioritize compression efficiency.
RAF at a glance
RAF
Convert to RAF when preserving Fujifilm camera originals or handing files back into a Fujifilm-oriented raw workflow.
It is appropriate for archive masters and non-destructive photographic editing.
