how do I collage two or more videos into one shot?
i would like to add some found historic footage to some footage i shot myself.. How do i collage two videos into one.. i would like to seemlessly combine various images and not lose sync with the live music footage.. but be able to add my own imagery on top.. this should be very easy but seems very difficult...
i guess i can use transitions but i always have a hard time keeping the audio synced.. . i am not familiar with the new imovie . i was an expert five years ago.. the new version seems very difficult.. should i get a book?
