RAW footage is separate media files in high resolution. One take= 1 file.Usually cameraman doesn’t turn his camera off (walking to or awaiting for something)to make sure he catch all important moments, also sometimes he makes double takes of something - that is why RAW footage contents a lot of extra(trash)footage. Also sometimes photographers, quests or service staff of the events may step into the camera frame interfering the shooting process.Postproduction includes:
watching all the footage long
cutting off all the trash or technical footage
composing and correcting of takes
final reviewing of all the video long
That means 1 hour footage= at least 3 hours of editor’s work. Or even more if we use voice over or/ and music over, special effects, animation, etc.
What is the difference:
VCD (VHS-video cassette aprox. 352 x 240)
DVD(720 x 480)
HD-720p(1280 x 720)
Full HD-1080p(1920 x 1080)
Ultra HD 4K(3840 x 2160)
We don't make DVD for DVD players - because DVD resolution is very low - 720 x 480. When we say DVD - we mean FullHD (1920 x 1080) video on DVD disk for PC (computers).
