Mute audio section using MediaConvert

0

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

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.

Setting up an assembly workflow job : https://docs.aws.amazon.com/mediaconvert/latest/ug/setting-up-an-assembly-workflow-job.html

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.
