What is cineform?

"Finally, for those more technically minded, the DVCPRO HD codec compresses image data using a variation of a DCT (discrete cosine transform) algorithm. DCT compression divides images up into small (usually 8 pixel by 8 pixel) regions known as "blocks". Each block is transformed and compressed separately from all other blocks in the image. Under stressful (highly complex) images, these blocks begin to break down, yielding "block artifacts" familiar to many people. The transform structure employed by CineForm's Visually-Perfect codec uses a Wavelet transform that never breaks the image into small regions, eliminating the possibility of block artifacts that often accompany DCT compression algorithms."

Above, quoted from here. Not only does Cineform have manageble file sizes, it is good if you have to do multiple generational renders for say CC, then composite in an element, etc, rendering many times. DVCPRO HD, whilst a good camera aquisition codec, imo, starts to break down when you render back to that same lossy codec, especially multiple generations. See some additional comparisons of codec at OneRiver Media, under "4:2:2C" heading at the top. Try the "10x Generation" on the image generated for the Apple DVCPRO HD codecs.

Edit: check this out also.
