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.
GIMP Pattern at a glance
GIMP Pattern
Convert to PAT when you need to preserve or distribute a tileable pattern for use inside GIMP, especially for texture libraries, decorative fills, and repeatable surface treatments in illustration workflows.
It is the right target for reusable pattern assets, not for final published artwork.
