Thanks for the info and links… I didn’t know this function (Multicam) and learned it with various “how to” like the one you pointed out.
I spent hours fixing a very stupid thing and I’ll add the info here in case it can be useful for the next dummy that comes around like me.
When having one timeline for all the videos, it is super easy to open them all by double clicking on this “windows” logo and all vids open up which allows further modifications on each movie. However, I really struggled to get back to the main timeline video in order to switch the cams… I literally spent hours on this!
In order to get back to that “main” timeline, simply go into the menu in the timeline frame and close the “Multicam name” and voilà.
I’m really new to this and I did suffer (a lot) to put together this 20mn video but it is done and I’m quite happy with the result for a first attempt 😁
Thanks again for your help and comments!
