HEVC/H.265 in het kort
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.
3G2 in het kort
3G2
Convert to 3G2 when preserving compatibility with legacy CDMA handset recordings, telecom media archives, or workflows that explicitly expect 3GPP2-style mobile video.
It is useful for migration and recovery of old phone clips.
For current playback and sharing, MP4 is almost always the better destination.
