Adding FX to an old movie
Having recently purchased Hitfilm 3 Pro, I thought I might revisit an old movie I did 7 years ago. It is a 3 1/2 minute short film in MiniDV format.
I don't want to re-edit the whole thing in Hitfilm, I just want to add a few special effects (explosions, gunfire, missile smoke) to the original .avi file that I have.
Practically speaking, what is the best way to do this? Should I make a single composite that is 3 1/2 minutes long and add the effects to this? It is a bit unwieldy having such a long composite, but I can't think of any other way.
