HEVC/H.265 w skrocie
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.

If your workflow includes iTunes integration or requires maximum compatibility with mobile devices, AAC is the practical choice.
Video producers frequently convert audio to AAC when working with MP4 video containers, since MP4s typically pair with AAC audio for optimal streaming compatibility.
AAC offers significantly better quality-per-bitrate than MP3 while maintaining broad compatibility.
Choose AAC when you need smaller file sizes than lossless formats but better audio quality than MP3 at equivalent bitrates.
