Animation Codec
Overview
The Animation codec is best suited for two-dimensional animation and
computer-generated video content. It is lossy at quality settings from1%-99%, and lossless
at 100%. Animation at 100% is generally used as a "storage" or intermediate work
format.
Architectures Supported
Pros
- This codec is great for sequences of screen images, such as those
captured by utilities such as CameraMan and Spectator.
- Since it is lossless, Animation at 100% will not introduce any noise
into the video signal, which is why it is sometimes used instead of JPEG.
- The Animation codec works with all bit depths.
- It is slightly slower than the None codec, but usually produces smaller
files.
Cons
- At 100% quality, files compressed with the Animation codec may be quite
large.
- Images captured from videotape generally have visual noise which can
corrupt the inherent similarity of the pixels and make it more difficult
for the codec to achieve good compression.
Tips
- The Animation codec's performance and compression ratios are highly
dependent on the images being compressed. The codec is very sensitive
to picture changes and generally works best on images that have been generated
synthetically.
- The new G3 Macintoshes can play video which has been losslessly
compressed with this codec. This could be useful for previews of intermediate stages.
