Full Resolution?

[BachManiac]

Hi!

when I convert a DVD Movie with AGK the resolution is always lower as the source.

The source is always 720x576 in europe, the aspect ratio is mostly different but after the convertion the height would always be reduced and this I don't understand why.
On high-quality-settings the width is the same as in the source, but why?
In my opinion the width should be raised to get the full picture size in relation to the rectangular source pixels.


A 720x576 movie with an aspect ratio of 16:9 should have 1024x576 with square pixels in my opinion.

A 720x576 movie with 2,35:1 should have 1354x576 with sqare pixels.

ist it possible to set AGK that it makes such output Resolutions?

please help!

I want to archive my DVD's on HDD and therefore I don't want to loose quality.

kind regards!

You can set the width yourself instead of leaving it at auto.

If you really don't want to lose quality and want better control over resolution, don't use AutoGK. It does a decent job, but it's designed for ease-of-use over quality of output.

thank you!

but isn't it possible to set only the height and let set the width automatically from AGK by the aspect ratio? Because the ratio is mostly different and I have to try it out every time to get the right resolution.

thanks!

It's the other way around, you can only set the width, so yes, you'd have to work out the correct resolution each time. A simple method would be to use the full Gordian Knot with its active resize/crop preview so you can get it right in a few seconds, then transfer that width selection to AutoGK.

Using generic PAR –default in AGK– that’s correct.

A 720x576 movie with 2,35:1 should have 1354x576 with sqare pixels.
No. Only two versions of 720×576 PAL exist: 4:3 that stretches to 768×576 and 16:9 that stretches to 1024×576. Any other AR is created by letterboxing (using black bars). A typical 2.35 resolution would be 1024×432. The rest up to 576 is padded with black.

So if you only have 16:9 DVDs you actually *can* fix the width to 1024 and always be fine. Though imo upsizing like that is a waste of bitrate.

+ you gotta make the files pretty big to use those resolutions and get a good quality... And thats the biggest problem with n00b rippers in my mind they don't know how to choose the right size and res.

I'd say one of the biggest problems. :)

For example, BachManiac also mentioned wanting an AVI with a resolution of 1354x576, not understanding that 1354 is only Mod2 (only divisible by 2), and that AutoGK works in Mod16 dimensions, as it should.

In addition, upscaling to a resolution like that, no matter how large the filesize, won't improve the quality any, at least not using AutoGK it won't.

I set width for all my AGK processes at 720 and audio on auto except when the soundtrack is truly spectacular and then I go for keep AC3 and set the file size at 1/3 DVD. I mostly use Xvid as the codec and tick the sharp matrix box. These files look fine on my 16:9 Samsung played over my network. I've never experienced aspect ratio corruptions with AGK.
