Are Movies shot in a 480 resolution?

I know that a lot of older movies like Jurassic Park and Lethal weapon are coming out on HD-DVD soon. But I was wondering what kind of format they were originally shot in. Do movie cameras record in a 480 or 1080 resolution or something else? If 480, are these HD-DVDs just being upconverted to 1080 and re-recorded so that the quality will be just like your average up-convert dvd player would produce?Are Movies shot in a 480 resolution?
Movies are usually filmed on 35mm film at 24 frames per second. Film does not have scan lines like video so the 480p or 1080i question doesn't really make any sense.



While 35mm film is estimated to have a resolution equivalent to about 5000 lines this is not always the case. These are not true scanlines. It's just the approximate size of the grains on the emulsion.

So, what is going on? HD-DVD and Blu-ray HD discs will not be upconverted 480p as you suggest. If it were, it would be detectable and the hew and cry and outrage from the videophile community and consumers would be immense. I know I could tell the difference.



If their only digital master is 480p for DVD, they'll remaster from film at 1080p. In some cases, the studios may have already created a 1080p digital master at the time that they created the 480p master for DVD and will use that as the source for the HD-DVD or Blu-ray. A 1080p master can be downres'ed to create a for 480i recording, a 480p recording, a 720p recording, or a 1080i recording.Are Movies shot in a 480 resolution?
this is a good question ,any brainy guy .aroundAre Movies shot in a 480 resolution?
Knowledge is right. If you ever watch some HD channels that play old movies or TV shows you can see that the are indistinguishable from current HD programming most of the time. That is because if it is mastered on film it can be remastered in a higher resolution digital format. The reason we have not been able to get this picture quality in the past is because of low bandiwith with old transmission formats and because the format of TVs were lower resolution.
