Audio
Initiating Imgix Video
You must set fm=mp4 for Imgix Video parameters to take effect.
Imgix Video provides a set of audio parameters for controlling volume, normalization, equalization, noise reduction, and fade timing. These apply to all video output formats (fm=mp4, fm=hls, fm=dash) as well as audio-only extractions.
Audio-Only Output
To extract just the audio track from a video source, use fm=m4a, fm=mp3, or fm=wav. No video encoding is performed. See the Video Format page for the full reference including encoding parameters.
Use case
The unmodified source video — use this as a reference when comparing the effect of each audio parameter.
No audio parameters applied. This is the baseline output from
fm=mp4 alone.https://assets.imgix.net/Croatia.mp4?fm=mp4
