1. Define "compressed". 2. Define what you compress. The second is important: If your source is RGB information, 8 bits per color, and you process it to 422 YUV, then the number of bytes needed to represent the source is reduced (which could be a definition for "compressed"), but information is lost as well. However, you could also say that your source is the frame in "422 YUV" format, then "422 YUV" is obviously not compressed, but if you further process the frame to JPEG, then the result is compressed (for some definition of "compressed"). -- Hannes _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
