SR2 at a glance
SR2
Convert to SR2 when maintaining an archive of older Sony raws or preserving compatibility with an earlier Sony camera workflow.
In most modern pipelines it is a source or recovery target rather than a preferred new output.
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.
