Are you able to use the GK and MeGUI "calculators" outside of their applications?

As I don't use GK, I don't know what features it offers its users. Embedded or external. Cheers

After looking at the back of a few DVD cases I've found several other expressions, such as: Original Theatrical Presentation, Original Theatrical Exhibition, Presented in x.xx:x, TV Aspect Ratio. Cheers

What version of MeGUI does this? I am currently using version 2.3.1024. Can I simply enter in these values for SAR in the version of MeGUI I am using? Also I'm unsure when I would use 16:9 rather than 47:20 or 37:20? Is 16:9 for letterbox or nonanamorphic movies?

47:20 as a fraction, equates to 2.35:1 as a decimal 37:20 as a fraction, equates to 2.40:1 as a decimal All the above (fractions and decimals), represent the original movies aspect ratio. Which can be found on the back of the original DVD case Cheers

what i have encountered now a couple of times is, that the ratio on the back of the dvd cover had nothing to do with the actual ratio of the picture without the black borders.
@berrinam: somehow, the values megui reports and writes into the avs file have little to do with the values that i would put in (and which i believe to be correct) into the fields of, what megui calls "sample aspect ratio _ x _" (i tried with te most recent version .2065) i believe my little tool gives the correct values: http://forum.doom9.org/showthread.php?t=106929 so long, jmk |

With Blade Runner for example. When you play this DVD in a software media player (such as Media Player Classic) and take a "full screen" capture you will see this: - As you can see both the horizontal and vertical mattes are very poor indeed However, when you hard crop the mattes away from the above image you will see this - And when you divide 968 pixels by 414 pixels you get aspect ratio of 2.338 to 1 (2.338:1). Which is only 5 "horizontal" pixels away from 2.35:1. Or just 2 "vertical" pixels away from 2.35:1 Cheers

well, i had my biggest problem with "2001: A Space Odyssey" i took my quite a while to figuere the correct ratio out.
it is encoded on the dvd as: Aspect_Ratio=16:9 Picture_Size=720x576 but you have to crop it in this way: crop(2,52,-2,-52) which left me with a ratio of 2,16:1. which is quite a difference to 2,35:1, the value megui proposed... but also a couple of other movies are not really 2,35:1 some are more close than others, but if i set the par/sar/or whatever value, i want it to be exact! |

Actually 2001: A Space Odyssey was shot in 70mm film with aspect ratio 2.21:1. In DVD releases there are usually narrow bands of image missing from all sides (perhaps because the transfer was made from a 35mm 2.35:1 copy), but at least Amazon lists 2.21:1 as an aspect ratio for their 2001 DVD releases.

Yep some are wrong...
My copy of Lawrence of Arabia is described on the back of the DVD as being 2.20:1, when it's nearer to 2.157:1. And Dune, which is described on the back of the DVD as being 2.35:1, when it's nearer to 2.30:1. Which both equate to being around 10 vertical pixels off target... quite a bit Cheers

all i am trying to say here, even though the ratio of the actual picture (what did we call it again) might be off, if the par/sar/whatever value is calculated correctly, it does not matter. jmk |

well, you could just use the values provided by the d2v and the avs file -> and thats what my tool does.
the new version prints it out, too. and it should now work with every resize method till it gets approved: http://rapidshare.de/files/12751934/...r_0.2.rar.html |

Aspect Ratio Signalling (ARS) Calculation Tool
Okay,
Here is the first version of the ARS Calculator. I hope some of you guys will enjoy using it Download Link: https://forum.doom9.org/attachment.p...1&d=1139749825 At the time of writing it requires version 2 of Micro$oft's .NET Framework in order to run. My profound thanks goes to Moitah. Who was able to turn my design concept into a working reality. Many, many thanks.... Cheers

Hum ... long & interesting post !
so I've a question : is my way is right or fully ...bad... ? My way : For both PAL and NTSC DVD, I just crop up and bottom ( if side borders are not too large ) ... never resize ! And I know : > PAL : 720*576 -> 1024*576 > NTSC : 720*480 -> 854*480 So if my cropped frame is 720*416 (PAL) for exemple , my AR in MkvMergeGui is 1024*416 ... is it right or not ?! Thanks everybody |
