007 The World Is Not Enough : 1 CD or 2 CDs ?

[iparout]

Hi.

I have just finished encoding The World Is Not Enough and I am in a great dillema as to how many CDs to use for this movie.

The film is 123 min long and has a 701x434 size without the black bars.

I have encoded it both for 1 CD and 2 CDs.

1 CD version : 112 kbps VBR mp3 sound, 677 kbps (46,1% compressibility check)

2 CD version : 224 kbps VBR mp3 sound, 1333 kbps (90,7% compressibility check).

The picture on the 1 CD rip is a *little* noisy in the hi-motion action scenes, but there aren't many of them in the movie.

On the other hand, on the 2 CD rip version, the picture is very good, however I prefer using 1 CD for each movie and I also think that a 90% compressibility check shows that 2 CDs are an overkill for the movie.

Also, I am not interested in AC3 sound.

How many CDs should I use for the movie ?

Also, if anyone has ripped this movie, let me know how many CDs you used ?

Thanks. ;)

Hm thats similar to "Matrix"

You can use 96kbps ogg vorbis or a noise filter like convolution3d to increase compressibility

Otherwise you can wait until the final release of xvid (hopefully in the next days :D )

I hope that final xvid will get matrix on one cd with GREAT quality!

Personally, I'd use 1 CD. What resolution are you encoding to? You mention a size after cropping, but it's the size after resizing that's important.

The output size is 640x272.

hey i would shoot for either 96 or 128kbps vorbis audio and try lowering the res to 576 or even 544 instead of 640 to increase the bits/pixel ratio. you wont lose THAT much detail and it will decrease the blockiness.

The comp. check is sometimes misleading. I've done movies at ~45% that have looked good (perhaps not DVD quality , but good enough not to use 2 CDs).

Try encoding a small bit of the movie with the mentioned bitrates and check the quality. You may also consider lowering the resolution to 576 H. That'll probably bring up the comp. check to a more reasonable ~55%

I don't know but which resizing method you used, but they have quite an impact on compressibility. Try one with a higher compressibility to increase the percentage.

For compressibility: Bilinear > Soft Bicubic > Neutral Bicubic > Sharp Bicubic or Lanczos
For detail: Sharp Bicubic or Lanczos > Neutral Bicubic > Soft Bicubic > Bilinear

And almost every movie that you want to fit on 1 CD requires filtering of some sort. Personally I hate spatial filtering, temporal filtering usually works quite well. Convolution3D, TemporalSoften or TemporalSmoother are recommended.

You also didn't mention if you used B-frames, which are also highly recommended on 1 CD's.

i've used Sharp Bicubic since I want as much detail as possible, no noise filtering at all, and B-frames enebled.

This is not a good situation for such a sharp resize filter. Neutral bicubic is recommended. Go for 1 CD, IMO, and definitely follow the previous advice about using a lower resolution, such as 544.

As for the previous poster who thinks his 46% or whatever movies look objectively better than lower-res encodes, -- I don't suppose he's done enough side-by-side comparison. If he had, he'd not hold such an untenable position.

Would that be me? I don't think I ever said that in this thread.

Though my opinion is that you won't be able to see any real difference between say 576H 45% and 512H 55%. Do you claim so?

Macro-blocks should be apparent to anyone.

i just read this tonight, and it corrolates (sp?) with this discussion. talking about compressibility and such, and how without side-by-side comparisons, you can't tell the difference between certain things....
