swap field order sample

[len0x]

I was wondering if someone has a sample PAL vob/m2v file which has interlacing that can be fixed by switching "Swap Field Order" on in DVD2AVI? I personally never had such a source and curios how rare are they?

Anyway, if someone does have such source I'd very much like to have a look at it. Thanks.

while I'm at it - does anyone has example of telecined PAL source where 30fps->25fps conversion was made and can be recovered by repal.dll ?

hi len0x,

If you have one of the Hauppuge PVR lines, you should be able to get
whatever you want in "field Order" samples :)

I have the PVR usb (352x480 old version) but this unit does mangle up
the field order. I've only tested a few samples for a friend who has
the PVR (latest models - better ones) and I have helped w/ this same issue
because the user wanted to cap hi bitrate tv show (mostely Interlaced
tv shows) and then stream line it w/ DVD2AVI to a re-encode 352x480 CVD.

There's now a PVR/2 (USB 2.0) version, but I don't know for sure if this
is the exact model as the above (PVR-250/350) chipsets.

But, if you can't find samples, then this could be an alternative to
your quest :)

Good luck,

Unfortnately I don't have any of those devices to produce samples myself...

I personally never had such a source and curios how rare are they? Hi, I don't have a vob file, but with my Pinnacle PCTV card, almost all of what I capture, a simple field swap filter is all that is needed to deinterlace. (I use the internal one that comes with Virtual Dub)

Would some Huffyuv avi footage do?..

If yes, Im just uploading 1 second of Huffyuv footage for you
Huffyuv 384 x 576 25fps PAL B.G, 1 second (http://www.aussievideosearch.com/avi/huffyuv-384576.avi) File size is 5,441,536 bytes.

Captured using Onboard tuner from Pinnacle PCTV Card, coaxial input from rooftop aerial (FTA analog).

I normally capture at 384 x 576 (instead of 768 x 576, due to system resources), and then fieldswap and bicubic resize upto 768 x 576, or down to 384 x 288 depending on the intended use of that footage.

If you want to see how the footage looks, once fieldswapped and resized and then cropped (to remove black bars), you can download divx version 5.00 variants From This Page (http://www.aussievideosearch.com/cards.htm)

384 x 288 4 seconds is 892,928 bytes
768 x 576 4 seconds is 2,209,792 bytes.

Hope that helps

Thanks. Unfortunately I'm in need of testing DVD2AVI/mpeg2dec3 combination to see if I can detect shifted field order which can be fixed by changing the value in the d2v file. So presense of the MPEG2 source is crucial in this case...
