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.
RST at a glance
RST
Convert to RST when the content is headed into Sphinx or another documentation system that benefits from directive-rich plain text.
It is well suited to API docs, developer manuals, internal technical references, and documentation that needs cross-references, notes, code blocks, and publish-time transformations.
Use it when documentation semantics are more important than office-style page layout.
