We record a lot of family videos, especially when we travel or when the children have some event, etc. Especially the travel videos are then everything my wife records on her iPhone, everything I record on my Samsung phone and the bulk of the videos are what I record with my Sony A7C. I then get everything into one directory but then all the files have different naming conventions, so it’s a bit difficult to organize into a timeline. I think all of the files have their date/time baked in into the files so it theoretically should be at least possible to rename them to be able to sort them.
But then the real work starts, going through every single clip and trimming it and putting it in order into the timeline. So I wonder if there is some tool which can help with that.
I don’t know what you intend to eventually do, but just so you know, kdenlive can get really unstable with big projects like that. If your goal is to eventually edit them into one video, do it in chunks and save often.
