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.
EXR at a glance
EXR
Convert to EXR when the image needs high dynamic range, floating-point precision, render passes, or linear-light compositing.
It is ideal for CGI, VFX, and advanced HDR production pipelines.
