Aspect Ratio vs. Cropping (and my review)
quote:
can someone who's seen both releases explain this to me please?
measuring the aspect ratio of the tcf version it was a near perfect 2.35:1
i just got the jpeg sample of ctp's version and i measured the aspect ratio to about 2.3:1
so what are people talking about a cropped image? have the top and bottom been cut to compensate for a smaller wide picture, thus deceptively mimicking a more acceptable aspect ratio?
LOL. Aspect ratios and size/cropping ARE NOT THE SAME. they haver nothing to do with each other. The denotation of: xx:xx is a comparison of width and height . 4:3 aspect ration (i.e. Fullscreen) means there are 4 width blocks and 3 height. (similar to 800x600 or 1024x768 notation, but who the hell wants to deal with all those numbers? Its easier). 16:9 (i.e. Widescreen) is a lot wider as you will notice. Its more wider than if it were 4:3 (using simple math, 4:3 is the same thing, basically, as 16:12, so you see the ratio difference.) Why is the 9 height smaller than the 3 height in their respected ratios? Simply because it does the 16 first, and adjusts the 9 to fit to that proportionally.
Now lets talk about cropping. I work in a movie theatre and actually get to see a lot of shti you guys dont. Example: Did you know they shoot and deliver the video raw to theatres? Yup. When in the theatre and the masking tape that hides the extra width and height is removed, you can see the boom mikes they used to film the movie with. They leave em in! The movie is actually MUCH bigger than the screens. I've seen plenty of raw movies, and the picture is actually a good 5 feet above and below the screen and about 1-2 feet more ont he side (including sound lines). The theatre then fits the movie on to the screen (we are an older theatre so we use maskin tape over the lens). So, and I forget which movie it was, but lots of folks were bitchin about seeing the boom mikes in a CTP release. Those aren't their mikes (lol and why would they be? Are they using them cause the speakers are in the theatre seats where the mikes are pointed to? lol), thats bad theatre cropping and centering (if you see those and its cropped [with tape] then the theatre did a bad job and the movie isn't centered how it should be). Ok, sry for the digression, back to cropping vs. aspect ratio. A movie, if cropped proportionally will have the same aspect ratio because aspect ratio is width vs. height (e.g. if the original movie is 16 feet by 12 feet, and is cropped [or scaled, which would lose no picture data] down to 4 feet by 3 feet, the aspect ratio is the same. 16/12 = 4/3. Simple fraction reduction.)
So the aspect ratio might be the same, or near the same, but that doesn't mean it wasn't cropped. So what probably happened was that TCF filmed their on a larger screen where the theatre didn't cut out as much. Lets say their was a 16:12 and CTP was a 12:8. Same Aspect Ratio, less movie. Get it now? (all the number in these last two sections are made up. I dont really know what they used and cant be nothered to get the actual aspect ratio and stick it into a calculator and mess with it.)
Review: 7/7/? - If ya got TCF or hate angles, stick with it. If you love CTP, get this. I'm gonna get neither (i see em for free ne way :P )
