Crop Progressive 2.35:1 DVDs

[Trac]

A newbie question

Before I purchase Pro DVD-RB, I would like to know how difficult it is for a standard resize of 2.35:1 DVDs.
They will be movie only Encodes DVD9>DVD5.

The standard would be the same for all 2.35:1 videos-
-AutoCrop top and bottom with 64 crop left and right.

If AutoCrop is not an option, I can easily detect the top and bottom bars for cropping.
All the DVDs are Progressive, so interlacing problems/commands are unnecessary.

Easy. You just add the resizing/cropping to the filter editor. Didn't follow completely -- but I assume you are cropping the black bars and sides to get it into a 16:9 anamorphic picture.

That was my plan, but for DVD backup I’m going to stay with the original.
No disrespect to DVDShrink, but I need a higher quality prog.
Thanks jdobbs

Here's how you'd add it using the Filter Editor (this example assumes NTSC) if you wanted to fill the entire 16:9 screen. If the source is PAL you'd adjust appropriately. i:SeparateFields().LanczosResize(720,240,96,32,528,176).Weave()
p:LanczosResize(720,480,96,64,528,352)The "i:" tells DVD-RB to apply that line only for interlaced sources. The "p:" only for progressive. This line should crop it to a 2:1 display.i:SeparateFields().LanczosResize(720,240,54,18,612,204).Weave()
p:LanczosResize(720,480,54,36,612,408) It will still have the bars at the top and bottom, but not as large.

In both examples you would be losing picture content on the right and left of the screen in favor of filling the TV screen more fully. You should also enable "Force Reencoding (for filters)" to ensure all the segments have the filters applied (especially if you are doing Movie-Only).

[Edited]Made a correction, I had two values transposed.
[Edited again] Did it again...

You could also just enable Pan & Scan (yecch!) in the IFO's video attributes and forget about resizing.

Don't resize by separating the fields, use a (smart) bobber, then resize and reinterlace..

Don't resize by separating the fields, use a (smart) bobber, then resize and reinterlace..I'm trying to figure how Bob improves it. Bob makes each field a frame, right? That requires some form interpolation for resizing before you actually do the cropping... Am I missing something? Can you post something so I can give it a try?

yadif(mode=1) #or other smart bob
AssumeTFF()
LanczosResize(720,480)
SeparateFields().SelectEvery(4,0,3).Weave()

Yes, I also recommend YADIF for a good performance-quality ratio. There have been quite a few posts about resizing interlaced material, scharfis_brain's posts are a good source of knowledge.
