Jagged lines on analog capture

[csaag]

Hooked a VCR up to my Aver Tv98 PCI card, played a brand new tape (professional, not a camcorder made tape) and any motion at all was just loaded with jagged lines when I played the captured AVI file on MediaPlayer. Was using VirtualDub for the capture with Huffy compression (320 x 240 capture res).

My system is an Althon 1.5 XP chip with a Maxtor 40gb 5400 rpm disk, 256 mb DDR ram, Radeon 7500 64mb video card.

Wasn't using any filters in VirtualDub. Is this the capture card or can the proper filters help to greatly eliminate this and if so what would be some filters to choose.

Thanks for any help.

Maybe interlacing vs. progressive? Field order?
Do you have a screen capture you could post here?

Thanks for the reply.
My intent is to simply make a DVD backup of a VHS tape to play on the TV thru the standalone DVD player. This may be a dumd question, but I would think then that I want to keep it interlaced. I'd have to check what settings I had on Vdub for interlacing etc. Another dumb question - Is it possible for it to look bad on the computer, but fine when viewing it on the TV because of a poss interlacing issue?

Of course you want it interlaced if it's going to be played on a set-top player ...unless you have HDTV and a progressive player, that is.

I was thinking out loud ....when it happens during motion it indicates a field order issue. If your field order is reversed it'll play the second field of a frame before the first. This becomes pronounced during high-action scenes and appears like a ragged edge or motion blur.

Definitely it can look bad on the PC when it looks good on the TV. This is more common than the reverse since the TV is more forgiving.

I suggest you grab an image and post it. "A picture is worth a thousand words"

Interlaced material will look anywhere from mediocre to pure shit on a computer monitor. But it will look fine on a television.

Post the image. Let's see what's up!

I imagine I can use the editing features in VDub to grab an image? Never used VDub for editing before, just strictly capture. But I'll play with it tonight. I think I'll try taking a few minutes of captured video an burn off a VCD & see what it looks like on the TV also.

Sounds like a plan. Let us know how that goes with viewing it on a TV.

Well I tried to capture a few minutes, but for some reason VDub drops tons of frames. It wasn't doing this the other day when I last used it. I must have toggled something on the menus. Too tired from a long afternoon of patching my driveway (ugh!) to play around any more tonight.

Did try downloading IUVCR as an alternate. Captured a few minutes fine in .AVI (so at least I know the dropped frames wasn't from the VCR), but when I opened up TmpgEnc, it couldn't read it. I have 2.5 plus & am registered. I figured I needed an updated and sure enough there is a later version. But when I downloaded the 8mb self extractor & ran it I entered my name and it show a small window with my name & current serial number, but it still forced me to hit the register button & wouldn't take my serial #.

The other strange thing is both the preview windows of VDub & IUVCR looked like it had a problem with the horizontal hold. The top 5% or so of the picture was showing at the bottom of the window. Did hook it to the TV and no problem there.

Sooo I'll have to try this all again tomorrow or Sunday...

Cropping problem solved, in IuVCR under the video tab, the configure tab for the driver was set to 'SECAM-D' I'm guessing that this set it for any program that used it. There were 3 choices for 'NTSC' M, M-J, and 433
I'm not really sure which one to use, although I can't seem to up fps past 25 for '433'. What's the difference between the 3?

Can capture in Vdub once I tried resetting several fields. Although once I setup everything for another run I now get an error in VDub about initializing capture file when I start a capture. Never had that happen before. tried rebooting to no avail.

Most of the jagged lines appeared whenever I had a height res > 480 (was trying 488). Guess I can live with 480.

Was also able to get my serial # into the latest version of Tmpeng Plus
