So I have decided to unite in a whole video everything I have of my child. I wanna render it in a sole .mp4 file with 1080p, good audio, etc. I want all that (1:50:00) in 2GB or 3GB, no more. I've seen videos accomplishing this smoothly, but everything I've tried so far ends in 9-12GB.
What I need to do to achieve it?
