KVCD: how to get aspect ratio correct?
 

Now I am really confused.. Okay here goes (I am newbie)

I use smartripper to get vobs to hard disk, then dvd2avi to get d2v file and audio. Then TMPGenc to encode with KVCD.

My problem, aspect ratio's. (and I don't know what FitCD is?)
I am a PAL user.

I have 2.35:1 and 1.85:1 Pal Dvd's. Firstly with 2.35:1 how to get aspect ratio correct? So far the closest I can get is by setting source aspect ratio to 2.11:1 (as there is no 2.35:1), video arrange method to Full screen and new aspect ratio to 16:9. This is basically correct output aspect in PowerDVD (with keep aspect ratio setting switched on) but it has double letterboxing?

Should I be using FitCD and use video arrange method as centre with borders?

Download FitCD here:

Then open your .d2v file with FitCD. FitCD will generate an AviSynth script with correct resize parameters ready to feed TMPEG.

For PAL Widescreen movies, set the Video Arrange Method to [Custom Size] and make it 352 x 432. This will give proper 21:9 or 16:9 aspect ratios from anamorphic sources (ie. DVD, DTT, Sat, etc).

Ok thanks for the info Kwag and energy80s. I will give FitCD a go.

One other question I have is regarding the black fill in lines top and bottom. Does this use bandwidth? ie does the encoder need to store information for these in the resulting mpeg? Or is this what FitCD gets rid of by setting the correct resize paramaters and adding static borders?

Thanks again guys.

Hi Hazza:

It doesn't take bandwidth. For example, if your .avs script produced by FitCD has something like this:
AddBorders(0,64,0,64)
You're masking an area with "black" bands.
So the black part doesn't consume data. ( sort of )
In theory, a black screen will have a data rate set by the minimum that the mpeg encoder is generating.
If it's a KVCD template, a black screen will be producing a constant video bit rate of 300Kbps. Which is the MIN value.

The same way that a full screen movie will take a hell of bandwidth, and not many will fit in one 80 minute CD-R.

You'll get around 90 minutes on a CD-R if your movie is a 4:3 full screen.

Hey Guys.. Another question. I now am using FitCD to resize. I select the source, 1/2 dvd as destination and create the avi script. Feed this into TMPGEnc. Left the aspect ratio's default and it comes out with the sides chopped off. About 4 cm's off each side. And the vertical size is slightly smaller than what it should be. The source is DVD 1.82:1. What should I choose in TMPGEnc for source and destination aspect ratio's and video arrange method?

Sorry forgot to include the avs script. :roll:
