Anamorphic widscreen the more i revise the more confused I become? I've got a DVD (collateral damage) which claims to
I've got a DVD (collateral damage) which claims to be 1.85:1 widescreen, it is encoded organic at 720x576, so streached it should be 1066x576, here's thee thing though, most of my players read it and play it at 1024x576 (16:9) and when i looked at the crude image it have 85 pixel top/bottom black bars presently 576-85-85=406 and 720/406 = 1.77 (16:9) so now i really am confused, someone please minister to
Answers:
anamorphic widescreen means its widescreen minus the black bars at the top and bottom....thats what i thought On DVD, "anamorphic" refers to what's known as anamorphic fortification.
How this works is that the image is transfered as 16x9 on a 4x3 paddock. When played back in need anamorphic downconversion or played on a display that does not compensate for anamorphic formatting, the image will appear to be vertically stretched.
On a display next to an anamorphic mode, the lines are compressed closer together (or stretched horizontally), making the image appear to hold about a 20%-30% increase surrounded by definition although the horizontal line count is never changed.
Anamorphic widescreen transfers on DVD form more efficient use of the available resolution on conventional 4x3 video that would otherwise be shrunken to black bars on conventional letterbox widescreen transfers.
But, again, anamorphic enhanced video must be presented correctly for the imagery to appear properly. This is done either by downconverting the doll to 4x3, which reduces the resolution, or playing the video on a set specifically capable of properly displaying anamorphic video.
And, you should know that, simply because a transfer be done anamorphically, it does not mean that within will be no black bars. There will still be black bar top and bottom whenever the image is wider than the peak (letterboxing) or black bars departed and right whenever the image is taller than the peak (pillarboxing).
Addition:
The thing you stipulation to know is that there are a few different aspect ratio in show. 1.85:1 isn't the only aspect ratio explicitly commonly used. You also have aspect ratio like 2.35:1, which is a bit wider. There are others, as resourcefully.
