3rd Strike head to head japanese cabinet tournament with the $100 1st place bonus is on this weekend (SATURDAY)! All you guys need to come down and bring your game faces. This is some serious shit! :wow:
Here’s the problem Scott – I tested the vga input and that too has this overscan issue. Unless there is some other way to do it, it’s staying as a 480p set unfortunately.
So if you read below, I think we are both right, because your primary question, as I understand it, is whether a 480p master of a movie would fit on a single dual layer DVD. I think the answer is no. I think the uncompressed 480p master is much larger than what fits, so technically, we were both heading in the right direction. Blu-ray or HD DVD can better present a true 480p as well as better formats. I wonder though if Blu-rays are really displaying all that is possible, or if they aren’t making max use of the technology.
Scott, just to seal the deal – the word I should have used was “encoding” (from the AVS forums on a discussion of blu-ray vs DVD output to 480p):
"Basicly DVD is 720480 in luma, but the chroma is just 360240. So the chroma gets upconverted more or less when you send a 480p signal.
With BD you have 19201080 in luma with chroma that is 960540. So if you send out the image as 480P you basicly downconvert the chroma.
That leaves a 480P signal from HD source with chroma res that is 4X as high as a 480P source from DVD.
Also you benefit greatly from the HD encodings that will have less artifacts then the DVD.
Resolution is just one part of the equation of great PQ."
Also:
“It’s one thing to discuss the native resolution of the video (1920x1080 for HD, 720x480 for DVD), but realize what the MPEG-2 compression of DVD does. It breaks up the image into 8x8 pixel blocks and converts them into DCT coefficients, so it’s really 90x60 blocks that are stored on DVD (at least for I frames). This is where mosquito noise and edge effects really come into play. An HD video downcoverted to 480p will look nearly as good as the uncompressed 480p master.”
“Because of the 4:2:0 encoding MPEG-2 DVD’s really have a chroma resolution of 360x240. Since BD’s have a chroma rez of 960x540 it is easy to get a full 480 line chroma rez display out of them, effectively 4 times as many ‘chroma pixels’ as a DVD on a 480p display. So color is potentially more detailed.”
