On the assumption that you are PC rather than Mac…
I’ve used many editors over the years starting off with Windows Movie Maker.
It was the most easy to use/pick up but you very quickly run out of functionality. Vids shouldn’t all be about the fade between pics or spinning windows etc but it just seemed to lack some of the basics.
Plus once WMM moved from a downloadable file to an online process the whole system went to hell. Hated it.
After searching around for a few others I moved on to Adobe Premier elements v 7 ISTR. This was very hard to pick up but once I understood it I got some very pleasing results. However it has it’s little foibles which annoyed me such as when rotating footage the reproduction was poor, plus an unexpected download/update seemed to deliberately screw up any music I overlaid.
So again after a few tries of other software I moved onto GoPro studio. Again relatively easy to pick up how to use, it has plenty of functionality although you are always looking for that one ‘extra’ effect that would make the movie spectacular.
However, it is very, very buggy. It doesn’t like it once the ‘project’ file i.e. the file that contains all your edits, transitions, footage, effects etc gets above 3,000kb. Very easy to do on even a short 3 minute movie.
it’s a commonly encountered issue if you Google it. I overcome it by saving numerous efforts i.e. import footage and convert, save as movie_file_v_1, do some quick editing, save as movie_file_v_2, add some titles, save as movie_file_v_3 etc. then when it inevitably does crash you can revert to a previously saved version rather than starting from scratch.
it can still be incredibly frustrating though.
I stick with it cos i like the results and especially the various colour washes that can really enhance most footage e.g. the protune or candy colour option.
examples are available if you want to see edited footage.
