MediaConvert Remove Audio During Processing

Question

Hello there.

I am using MediaConvert with great success. We have built a solid workflow that auto processes videos uploaded to an S3 bucket. The mediaconvert job settings are set in a JSON file that are picked up and used when submitting the job.

The problem I am running into is that I want every video uploaded to have the audio removed when processing and not included in the processed result.

Researching led me to this stack overflow post -> https://stackoverflow.com/questions/72403314/is-there-any-settings-available-in-aws-elemental-mediaconvert-to-remove-mute-the

It's lacking some details. I have experimented with some different JSON settings to no avail. I don't see where you can actually set the gain to audio tracks to -60. Either this is not possible or I am just missing the specific setting to change.

Does anyone know where this is at? Thank you!

This is an example of some json I tried:

"RemixSettings": {
                    "ChannelMapping": {
                      "OutputChannels": [
                        {
                          "InputChannels": [
                            {
                              "InputChannelLevel" : [
                                {
                                  "Gain": -60,
                                  "InputChannel": 1
                                }
                              ]
                            }
                          ]
                        }
                      ]
                    },
                    "ChannelsIn": 1,
                    "ChannelsOut": 1
                  },

Answer

Hi there. The solution you are pointing to is actually not removing the audio, but just turning the volume down and effectively muting it, which would still require some processing I'd assume.
To simply remove audio from being processed at all, and therefor being completely removed from the output, you can remove audio from the Output preset, using the AWS MediaConvert console (see screenshot below):
