Mute audio section using MediaConvert

Question

I have two files: one is audio-only (mp3), and the other one is a video file (mp4). I need to mute a section from these files. Is it possible to achieve this using MediaConvert?

Example:
Suppose that one of the files has 10 minutes of duration, so I need to mute it from 00:02:00 to 00:05:30

Later on, I need to do something similar for video files to remove the video section from a video. It's not necessarily cutting the video but put a blank image to cover the content of a video for a specified section

Answer

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.
