Use of "crop" filter legal?

[laserfan]

Today I tried my very first filter with DVD-RB Pro. It worked!!! But I wonder if the resulting titleset is going to play w/set-top DVD players. I know, why not spend 40 cents and see; well, I'm cheap, but more importantly already I see that it doesn't play w/one of my PC players, PowerDVD 5.0.

Here's what I did:

1. Made a DVD titleset using NeroVision Express from an HDTV program

2. That transport stream oddly had a white line along the bottom; therefore so do the NVE-created VOBs

3. I got the bright idea to re-make the titleset using RB and the "autocrop" filter; this worked!!! (got rid of the line) but...

4. The resulting VOBs are now 704x464 not 720x480 (I used HC 0.16 and autocrop(mode=0,wMultof=16,hMultof=16,bottomadd=4)). I had to put-in the Multof parameters to make HC happy.

So--is my VIDEO_TS ok despite the non-standard resolution? Or was my crop filter setup wrong? Or did I go about this wrong to begin with? Maybe I should have cropped the 1920x1088 file up-front, but I don't know what tools I would use to do that. I looked at VdubMod but I can't even see the cropping buttons in the huge preview window (again 1920x1088). What to do.

no.. the vobs are not okay

after the crop, use an addborders command to add black bars and get back to 704x480 or 720x480, or use a resize to do the same by stretching

if you started at (ifos are) 720x480, i recommend going back to that

same with 704, just addborders to get back to what you started with resolution wise

Be careful with resizing. You can change the aspect ratio is you don't do it properly. It IS possible to resize interalced source, just be careful: http://forum.doom9.org/showthread.php?threadid=74906

Thanks guys, I will look into addborders to get back to 720x480.

The "filters" stage of my video larnin' process is off to a shaky start! But at least I FINALLY got going thanks to jdobbs and RB!
