Lossless cropping

[gerbo]

Hi there,

here´s my problem:

I have a 770MB Divx3-Movie here on my harddisk.
It still has the black bars on top and bottom.
What i want to do now is to remove the black bars,
hoping to gain some MB to make the movie fit on
a standard-CD.

And here´s the question: ;)

How do i manage to crop the film without reencoding
(reencoding caused a horrible quality in my recent tries)

Hi-

How do i manage to crop the film without reencoding

You can't. You could try and cut the opening and end credits (although that may not make it small enough). Although reencoding will result in a quality loss, it should still be OK. So if you get "horrible" quality when you reencode, I'd say you're not doing it right. I've found that about 95% of the movies available for download are just garbage, and you should be able to do a better job yourself.

It's an answer, but I don't know how helpful.

Ok ... that must be a rare movie or something so that u couldn't get it on DVD and rip it .. :) ... anyhow ... I faced this problem with many movies as manono says ... many movies available for download r garbage ... but not 95% ... :D ... I think u r talking about the old rips ... before the invention of SBC and Nandub ... the days where we couldn't imagine such an improvement in quality of ripping .. though ... there r many movies out there r encoded badly ... in the case of gerbo .. the movie contains black bars ... ok ... here is what I do if I couldn't get the DVD and rip it myself ... and that solution only if the movie worth it ... and the quality of the movie with the black bars r still fair enough ... I saw movies with shit quality and the black bars were there also ... so here what u have to do ... but it will take a long time ... u must reencode the movie using nandub ... and using some filters ... as follows ...

- Null Transform (Cropp the Black Bars)
- Resize (Depends on the length of the movie .. Usually I would use 640X272)
- Smart Smoother (Diameter 5, Threshold 30)
- Temporal Smoother (Filter Strength 3)

It will take 10-20 hours ... depending on ur Processor ...

I did this for 3-4 movies .. one of them is Rocky V .. I couldn't find it anywhere else ... and it is not available on DVD where I live ... so I did this .. and belive it or not .. the output ended better than the original movie ...

Hope that would help ... :)
