editVideo software
edit1- Is there any software that can join videos like this? I know how to join clips, means one clip is over, then another starts, but here two videos are playing together side by side.

2- In youtube videos, a video or some picture is shown but we hear the voice of the youtuber, his voice can be heard muting the audio of original video, how is this done?
He is describing a video and his words match with the pictures and videos that appear at exact time. 2402:3A80:1C40:78BD:1D53:B1D5:A769:9B1 (talk) 05:30, 14 November 2022 (UTC)
- For 1 you can use ffmpeg:
ffmpeg -i left.mp4 -i right.mp4 -filter_complex hstack output.mp4Graeme Bartlett (talk) 09:20, 14 November 2022 (UTC)
- Most video editors allow one to extract an audio from a video and to replace it by a new audio. So one can extract the original audio, modify it by mixing with an audio of the commentary, and then add the modified audio back. --Lambiam 21:03, 14 November 2022 (UTC)
