There are three main methods for capturing (or recording) an animated frame
The simplest method of recording animation is directly to a video camera that has a frame record mode. It is simpler to set up than involving a computer, less bulky and you can animate on location! Not all cameras have this facility, but it is a lot of fun if they do.
How many frames you capture varies with the camera model, and this can have implications for the timing of your animation. Check before you start!
Also record 10 seconds of blank at the beginning & end of your animation.
With this method you are using the computer to store animation your animated sequences made the 'traditional' way. This is not computer animation where everything is generated in the computer.
A camera is connected to your computer, and all the frames are recorded on the hard drive, via dedicated software.
The chief advantage is you can watch things back immediately, and preview before proceeding too far. The disadvantages are you will need a relatively fast computer, and you still need a video camera!
Some cameras automatically power-down. If you use mains power & remove the cassette, this should stop happening
There are a number of different systems available to record animation for both mac and pc.
This site does not deal with traditional celluloid film, but there are some wonderful things you can do with film and animation: such as drawing directly onto film, working with a super8 film camera, or even with a classic bolex 16mm.
