[Discuss] Please help edit an mp4 file

[E. William Horne]

My Quaker meeting has been having get-togethers via Zoom video 
conferencing, and our host recorded a recent meeting on the subject of 
de jure segregation.

However, part of a video that the host streamed into the Zoom video 
conference was defective, so I'm looking for open-source software that I 
can use to cut that part out of the .mp4 recording of the meeting.

All leads appreciated, and all suggestions welcome. Thank you for your time.
