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.
FITS at a glance
FITS
Convert to FITS when preserving scientific image data, observation metadata, or instrument-derived captures for astronomy and research workflows.
It is the right target when measurement context matters as much as the picture itself.
