Video Codecs Explained

Understand the role of codecs versus containers and how the common codecs advertised by FastConvert differ.

What matters

H.264 is a broadly compatible baseline choice.

H.265/HEVC can improve compression efficiency but needs better decoder support.

Step-by-step

  1. Step 1AV1 is a newer codec aimed at efficient compression, with heavier compute depending on encoder.
  2. Step 2VP9 is widely used in WebM-oriented workflows.

Keep the workflow local

FastConvert is positioned as a local Windows media converter. The conversion itself is performed through FFmpeg on the machine rather than sending the media to a browser upload service.
