Deleting or Suppressing Cough in Video

[Officer Sausage]

I made a video of a person giving a speech. The originals are shot in mp4.

the speaker coughs at one point

I am using Linux Mint 19.1 with avidemux.

I need to convert the video from .mkv to other formats to upload it on the internet

so I think the format may effect how it can be edited and saved.

when I have attempted to cut the cough out, avidemux tells me the cut is not on a keyframe so the video will be corrupted. If I change the format, I am able to make the cut in avidemux but the video won't play, so must be deleted.

I would like to cut the cough section out but if that is not possible, at least suppress the sound.

Any help appreciated.

The video and audio are two separate streams inside the file. You can open the file in Audacity (audio editor) with the FFmpeg
add-on enabled and it will allow you to work on just the audio. When you've suppressed the cough you save it as a new
audio file and recombine it with the original video to a new file

If you'd rather edit the video and audio, you'll need something like VideoRedo ($$),
comes with a trial but not sure of the limitations

Depending on how obvious the cough is physically, you might be able to get away with not even editing the video, but instead just dip/mute the audio.
