Aspect ratios

Post by alec »

First of all thanks to all those who post and send captures of actresses and apologies for being so far behind with the forum posts, but the subject of this post is not irrelevant to being so far behind.

There's often a problem with video capture software (there is with mine) in that it often stretches images vertically. This isn't always noticeable, but sometimes it is. (I suspect it may be something to do with the screen resolution used on the computer.)

Please, if possible, try to correct the aspect ratio of the capturing software. If it isn't possible, please could people try to correct the captures in image processing software after they've been saved. (I recommend Irfanview if you don't have any already.)

Unless it's a widescreen film the aspect ratio should be 4 by 3 (including the black bands at top and bottom if it's a letter box image). Many of the images posted and received by e-mail are 720 by 576 - this gives a vertically stretched image. It should be 720 by 540. I suspect that in practice the height should be slightly more as 4 to 3 is probably not quite exact in practice, but 4 to 3 at least gives us a standard.

A modern widescreen DVD would be 16 by 9 (that is 800 by 450 for an image of similar size to the above) common size of caps.

At the moment, the bottleneck in getting pictures and other information into the database is us. If contributors could do a little image processing first, it would reduce this bottleneck - and also slow you down a bit. :)

Anyway, thanks again, but a pause would help me catch up. Contributors could use this to investigate the possibilities of their software. Since jj's caps are the right aspect ratio, maybe he could just have a rest. :)

The reason for this is that people have their DVD player set to capture in the original DVD resolution. In the case of PAL dvds this is 720x576 which corresponds to 4/3 because pixels on a TV are not square like on a computer monitor. Software DVD players resize the picture to 720x540 during playback.

PowerDVD can be configured to capture the original or the adjusted resolution in Configuration->Tab Player->Advanced button->Tab Snapshot->Original Video Source Size = 720x576 / Current Video Window Size = 720x540 (if you have not resized the window manually)

Hi Candela,

Thank you for the tip !thumbsup! In my case, it did not give a 720x540 format, but using the third option (typing 720x540 directly) works.

I also encountered another related curious behaviour.
When I make captures from a DVD that is in recorded LP format then they are strongly squeezed, horizontally.

In my case the program that does the captures is not the program that plays the DVDs though...

The same thing happens with Power DVD.
