I was merely suggesting that using 60i instead of 30i has historical precedent. TV always used the field rate in the past, so why should we suddenly become confused today? Field rate and frame rate are the same for progressive, but not for interlaced. > I believe the TV world is finally ready to admit that > interlace sucks, but the legacy will be with us for many > years to come. Now that CRTs are rapidly leaving the scene, and that progressive HDTV cameras have become available, I don't see too much reason to continue with interlaced. But again, it never seemed like an issue to me, because all DTV standards out there can do just fine without interlacing. All DTV receivers fielded to date can do just fine without interlaced formats too. So this is not a big deal, as far as I can tell. At most, production facilities would have to go through some sort of migration, but that's it. And production facilities can migrate as they replace older equipment, switching over at their own pace, no need for any major industry-wide coordinated effort.
