CUR at a glance
CUR
Convert to CUR when preparing or preserving cursor assets for Windows applications, themes, or interface restoration.
It is useful when pointer hotspot behavior must survive alongside the bitmap itself.
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.
