Hi guys,

I would like to know how to sync 2 videos together, i.e One Video which has a chessboard with an author presenting a game analysis, and the other were 2 guys playing an OTB game.

You might have come across such videos on youtube or other sites like chess.com, chessbase.com, etc. Take a look at this example, please: https://www.youtube.com/watch?v=M5qtjq1NsH4&t=2s

What are the technology and steps needed to accomplish this task?

Use scene that shows all videos at the same time.
Record that scene to local video file and make something in the video move so it is easy to see when it occurred.
Load that saved video to any program that allows you to move frame by frame. Use that do find out delay among videos (in milliseconds, so if you have frame count you have to recalculate to milliseconds).

In OBS add filter called Render Delay to video that is not delayed and enter delaying value (in milliseconds). that would make that video delayed same a other one, so they would be in sync.

Audio is synced in Advanced audio properties. Principle is the same, add delay to audio.
