DVL-Digest 555 - Postings: Index DV vs MPEG compression shops selling sony camera in m DV vs MPEG compression - "Perry" Jan posted: > I was referencing Beta SX which is MPEG2 422@ML, GOP of 2, which has a heavier compression per frame than DV, of course if you were referencing the MPEG2 422@ML GOP of 1 then that is a different subject.< What I said Jan was that DV compresses each frame heavier than MPEG2 422@ML compresses the I frame. MPEG2 gets its extra efficiency from using inter frame redundancy, and therefore doesn't need to compress the first (I) frame so much. This is as well since using DV sophistication over more than one frame would be beyond the processing available in current codec chips. It is of course true that the use of MPEG leads to other problems but as you say, that is another subject. All this is beautifully explained in your Panasonic booklet. I can only say that if you stuck with what that says, then I wouldn't have to keep correcting your misleading statements.
