# Add Metadata to File
|
||||||
|
ffmpeg can add metadata to files using the `-metadata` flag. In the profiles described below, this is used to add a comment describing the profile used to create the file (e.g. `-metadata comment="x264 720p CRF 27"`).
|
||||||
|
|
||||||
|
This comment flag is visible in Windows file details.
