- The page describes a 6% safety margin and a second encode if the first output exceeds the target.
Field notes
The page says the tool estimates a bitrate from video duration, accounts for audio, and leaves a 6% buffer below the chosen limit. If the target is too tight, it describes stepping down through a resolution ladder before encoding; it also says the result is checked and encoded once more if it overshoots. The listed inputs include MP4, MOV, WebM, and MKV, while output is MP4 with H.264 video and AAC audio.
