Transcoding

Transcoding decodes and re-encodes media, often to change a codec, bitrate, dimensions or other delivery property.

Updated 2026-10-29 · Topicut editorial

Meaning

Transcoding decodes and re-encodes media, often to change a codec, bitrate, dimensions or other delivery property.

A practical example

A high-bitrate source may be transcoded to a smaller delivery copy while the original is preserved.

What to check

Every new encode can introduce changes or losses. Keep track of which source and settings produced the accepted output.
