It seems to me that you should contact a specialist who will help you deal with all the technical issues. I can only recommend a good video editing app for you. I have been a professional video editor for a long time. And recently, I came across the site. I really immediately really liked the app in use. So if you have a powerful computer, it will be very easy to learn how to edit in it. Moreover, if you have editing experience, you will quickly learn how to make cool videos there.
