white flashes in huffyuv capture with cropping

[sh03z]

I recently was capturing a digital video tape (home movie) to *.avi with huffyuv planning to burn to DVD in the end.

I think I found my mistake, but I wanted to make sure...
I cropped it when I was capturing it, so perhaps my resolution was a little smaller than 720x480, such as 718x478 or such...

However, some white flashes did appear after I resized the picture to 720x480 with an avs script and encoded the *.avi's with CCE SP...

Was my mistake cropping before, instead of cropping after???
Is that why I saw the white flashes around objects in my video???

Also, I was playing around with Vertical Reduction in virtual dub, which takes out the interlace lines for me...I would capture at half vertical res (1/2*720), however before I encode, my avs must resize it to the DVD standard of 720x480.

Thank you for your time, it might save me a lot of trouble to find the cause of my problems so I don't waste anymore captures.

If you cropped during capping to 478 vertical, you should letterbox it to 480, not resize. By resizing vertically, you screw up the interlacing. So add two black lines either at the top or the bottom and it should be fine. (don't add one line at either side, that would not work either :) )

p.s. if the source is already digital tape, why capping analogue?

Did you say you use Virtual Dub to deinterlace? You shouldn't deinterlace if your going to output to DVD. DVD's are interlaced, so by doing that you're reducing the quality.

Why not just capture directly to 720x480? Then you wouldn't have to do anything besides filtering and MPEG-2 conversion if you want to get it ready for the DVD.

I don't know how to capture to digital...

thanks for the input, let me check on digital capture, brb

I checked and I didn't really see any Digital video camcorder thingy

?

@2ZOD.COM

I tried that first, it produced MANY upon MANY lines all over the place...by reducing the vertical resolution, I lose a little quality, but I can see what's going on in the picture better...I.E. the moving parts are better, but definatly not the stills...
is there a place inbetween?

If you look at it after capping frame by frame it looks like that. But once you have made a DVD out of it and play that back it will look ok again.

Software DVD players deinterlace on the fly, and for a regular TV interlacing is not a problem.

Arachnotron, you have my attention now =D

I'm putting it on a SVCD to try that idear out

thanks!

**edit**

Arachnotron, you were correct...Thank you for saving me the hassle of half DVD res.

It played perfectly on my Pioneer DVD player via a test XVCD.
