Mute audio section using MediaConvert

Hi there,

Unfortunately it is presently not possible to mute / add silence to portions of a media file using AWS Elemental MediaConvert.

MediaConvert does support creating a job that combines assembly workflow features such as input clipping (transcodes only portions of your input), input stitching (joins more than one input file into a single asset), graphic overlay (inserts a still image or motion graphic at a specified time) etc. Input clipping and stitching would mean cutting the input which unfortunately is not what you require.

With reference to the video file, AWS MediaConvert does offer the ability for image insertion, both as a static image or as a motion image.

There is also the choice of input overlay vs output overlay.
