Need help with DVD resize

[Enkidu]

My dvd source is 720x480 (4:3) 1.333333, when creating my avs should I resize it to 640x480 (4:3) or not? And should I use Megui AutoCrop?

Another question, How can I use ffdshow together with Megui on mpeg2source?

Thanks

What is an avs?

[manono]

It's the extension AviSynth uses for its script files, like Movie.avs.

To answer the question, I'd crop and resize to 640x480 (or someother 1.33:1 ratio resolution). I don't use MeGUI, but I distrust all AutoCrops and prefer to crop myself.

Others prefer to leave it at 720x480 and set a PAR flag to let the player resize it at playback time.

Avisynth Scritp

Megui Autocrop was crop( 4, 0, 0, 0)

Is that a correct crop value on my case?

Is that a correct crop value on my case?

How am I supposed to know without the video or at least a pic to go on? Before the crop there's only a little bit of black on the left side and after the crop there's no black on any side? If so, then that's the right crop value. It also means that 640x480 isn't the right resolution, but if you make it that you might not be able to tell it's off by a little bit.

Isn't there a difference between a crop and a resize?

[Enkidu]

When i crop ( 4, 0, 0, 0) on the left side there's no black, but on the right side it's still there.. Maybe the right resolution would be 656x480 Crop ( 2, 0, -2, 0) ?

[hech54]

So are you cropping or resizing?

[manono]

He's doing both, but first he's trying to get the crop values correct. And again, there's no way for anyone else to know unless you post a few seconds of the video or at least an unresized picture so we can have a look.

Cropping the right / left thin black bars and resize. I want to get rid of the thin black bars on my video.. and I think I already know how.
Crop (2,0,0,0) and resize to 656x480. the problem is that one of them seems bigger..lol


Ok I will encode 1minute of video

[Enkidu]

The video was encoded using Crop(2,0,0,0) LanczosResize(656,480) (Sharp)
And the screen was taken from the original :

When someone requests a sample it usually means a sample from the untouched source, not a reencode. Anyway, the crop values are:

Crop(4,0,-2,0)

[Enkidu]

Many thanks and sorry about the sample..
Sorry to ask this again, the crop values are good with 656x480, right?

Thanks again

[manono]

It's kind of in between 640x480 and 656x480. Me, I'd crop a bit into the video and then resize to 640x480, like so:

Crop(8,0,-8,0)
LanczosResize(640,480)

Or, you can not crop into the video and then resize it to 640x480, which will leave a bit of an aspect error, but nothing too serious.

Ok thanks I will give it a try
