> What do you have in mind when you say lossless re-encoding ? If a frame has already been passed through a DV codec, then it is (theoretically) possible to re-encode it with no quality loss, by using the exact same bitstream. This is desirable for video editing systems where you might end up re-e

Hi guys - I've some done work on ffmpeg's DV codec recently, on contract for some of my clients. Quality-wise, the video encoder should be competitive with popular commerical encoders. In some of my benchmarks it attains higher image quality than Apple's software encoder. Which is not to say it is
