Scripted Action and Dialogue – actions that are scripted that performers will have to recite via memorization, telegram, etc. (used a lot in movies, news programs, etc.)
Unscripted Action and Dialogue – actions that are unscripted, and do not use any type of script. pretty much On-The-Fly recording. they are used to capture real settings without telling people what to do.
Title and Graphics – These are used to enhance videos by adding visual appeal, such as pictures, and could be used to compliment the video. you’re always going to want a pretty nice title how else are you going to get people to watch what you’re presenting.
Music and Sound Effects – Music and Sound effects are used to add musical appeal to the video you are trying to capture, these are used via sound files and this is where it becomes necessary to use compression and decompression, you’re going to want a really uncompressed file if you want some pretty solid audio quality. just some advice if you’re going into it anytime soon. I make you-tube videos… I tinker with this stuff every day 😛
