.mxf file resolution
Right now I am running Premiere so I have to convert the .mxf files off my HVX200 to AVI using the HD DV Decoder from Serious Magic. However, whenever I try to convert 1080 HD it gives me a file that is 1080 x 1280 with a pixel ratio of 1.33 which is definitely not HD. Is this the same size as the .mxf file or is it getting screwed up in the conversion process, It would suck if I can’t get true HD out of this camera. Thanks!

Yes, that is the native resolution of the DVCPro HD codec and the mxf files, and yes, it is true HD. Most codec’s use some form of prefiltering to cut down on bandwidth. DVCPro HD is 1280 X 1080 (or 960 X 720), 4:2:2 8-bit color @ 100 mbit/sec, which is 4 times more data than 1440 X 1080 4:2:0 HDV, which is still considered true HD, (even the Sony F900 Cinealta records 1440 X 1080 3:1:1, and most folks consider them to be true HD as well). Only a few cameras like the Grass Valley Viper record “true” 1920 X 1080 4:4:4 10 bit log.
The important thing to remember about resolution is that it only represents the number of samples, not what is being sampled. That is to say it’s just an empty address without any data. It’s the color data at that address that really matters,(well, ok, they’re equally important). That’s why the HVX with it’s codec looks so good.
If you really want to cry, go look up the actual pixel count on the CCD’s in the camera.
