A method for determining if uncompressed color video data was previously compressed and decompressed. Each block of color video data is examined to determine if the block was previously compressed with a predetermined compression algorithm that for example, selected fewer colors than were present in the original data. If it is determined that such compression has previously occurred, on recompression, a different algorithm is used to prevent introduction of color distortions.
