MPEG2 is potentially a better quality codec because it is not fixed at 25Mbps, allowing the compression ratio to be adjusted to match requirements, and is a more efficient codec allowing comparable quality at a lower bitrate (you can probably achieve similar quality to DV at somewhere around 18mbps with relatively clean noise free video that does not have a lot of fast motion, but can go higher is the video is noisy and you don't want to de-noise or let the noise "break" the compression or there is a lot of fast motion. All DV codec variants are also known for their staircase artifacts in diagonal lines due to less than optimum anti-aliasing (some variants suffer worse than others from this.) That said, as alluded to in the DV25 name, any standard definition DV codec variant (MSDV, Canopus DV, Pinnacle DV, etc) has a hard coded bitrate of 25Mbps. Canopus had their own version of this codec, which if I recall correctly was also licensed to Avid, that was a better quality implementation, but since it isn't built into windows, you needed the codec installed to play those files. Since it is a microsoft codec, it is built into windows and therefore the most universally compatible version. ![]() Is MSDV better than mpeg 2 for archival purposes?MSDV is essentially a derivative of Motion Jpeg, and is the microsoft version if the codec used in mini DV/DVCAM/DVCPro (a.k.a.
