Ps: Another neat function is that it can make an avisynth script based on the cropping made manually, example:ġ- rip your 'main movie'from your dvd to your Pc and use Dgindex to creat a d2v scriptĢ- open aspect, click on the Aspect ratio dropdown menu and select 'advanced'Ģ- click on open and select 'd2v project' and delect the d2v script, manually crop and click on ok.ģ-back on main menu select autosize and it wiil find the best resolution, click on 'save' and it wiil produce an avisynth script based on the cropping you made that can be 'fed' on to virtualdub to convert to divx/xvid without going in to the filters section, just select the codec and you´re away.

Just thought of sharing this as i find this tool extremely usefull when finding out the aspect of the movie and which resolution to use on my divx conversion. I use a tool called ASPECT for that,just manually crop the picture and it will tell you the correct aspect ratio of the movie on the dvd and the which resolutions you should use on your conversion to divx/xvid. I think theres an easier and less complicated way of finding out the movie aspect ratio. Grab a calculator and divide the pixel image frame 'width' by the pixel image frame 'height'. Save the cropped image and make a note of it's 'pixel frame size' (PFS)

Use the 'auto cropping' tool in your imaging software application. Paste/open the captured image into a reasonable quality imaging software application. Navigate to a nice light section of the movie, and select 'Snapshot' via the 'Video' tab. Play the DVD source in VLC (software media) player

Which you can enter into the ARS Calculator The resulting calculation will be 'the' Movie Aspect Ratio (MAR).

Plus the boundary between the matte and the image could be really messy (noisy)!īefore generating an 'cropped and resized' encode, I often find it useful to establish the actual aspect ratio of the 'image' element on the disc. but in reality, the movie aspect ratio quoted on the back of the DVD cover can often be quite a bit out. so it's five vertical pixels out.Īdmittedly five vertical pixels is not very much at all. However, the nearest 'mod16' pixel calculation is 720x368. 'should' mathematically contain an image of 720x363 (give or take a few vertical) pixels. When cropping the black mattes away, it's not always possible to obtain the 'theatrical' aspect ratio, within the confines of a 'mod16' encode.įor example, an anamorphic (16:9) widescreen NTSC DVD with a 2.35:1 movie on it. So the point of your tool is to allow the user to find a par that is better fitting the movie than the standard dvd 4:3/16:9 pal/ntsc one?Īs you know, a DVD source contains black mattes as well as the 'all important' image.

Who was able to turn my design concept into a working reality. Otherwise the calculator finds an equivalent ratio by multiplying each of A and B by 2 to. (or enter C and D to find A and B) The calculator will simplify the ratio A : B if possible. Simplify Ratios: Enter A and B to find C and D. NET Framework 2.0 in order to run.Īnyway. This ratio calculator will accept integers, decimals and scientific e notation with a limit of 15 characters. Second: Enter your 'ARS value' into the 'Custom' boxes (as shown below).Īt the time of writing both applications require Micro$oft's. You will need to use another application called MPEG4 Modifierįirst: Feed (drag and drop) your MPEG-4 source into MPEG4 Modifier. Third: You enter both these values into the 'ARS Calculator' and then press the 'Calculate' button to obtain the required 'Aspect Ratio Signalling (ARS) value. This can often be found on the back of the DVD cover, or on Amazon. Known as the, 'Movie Aspect Ratio' (MAR).

Second: You need to determine the actual aspect ratio of the movie. to this say: -įirst: You need to determine the 'Pixel Frame Size (PFS) of your MPEG-4 encode - Preferably without the black mattes. The ARS calculator will enable you to work out the required 'Aspect Ratio Signalling' (ARS) value needed to correct the shape. I have conceived the first version of my ARS Calculator (see link below).Įssentially, if you have an encode that's displayed at the wrong shape (see the port-hole).

And how to correct the aspect ratio of their existing 'square pixel' encodes. Capcut change aspect ratio.In response to all those people who have enquired about how to calculate the required, aspect ratio signalling (aka: PAR, SAR and DAR) values for their 'anamorphic' encodes.
