I been using Pinnacle card with a Phillips chipset to do all my capturing as it has better video quality then my ADVC110, however when I tried playing the video to my TV the video will play with interlacing artifacts, I used VLC as the player and Interlaced Mode Disabled, BOB lags too much on the TV and my PC. I thought I guess I need to burn it to a DVD so I won't see it... I did that but after I inserted the DVD the picture looked like BOB interlace mode on VLC on the PC which still isn't like the VHS to TV mode. I got MAD

I later tried the ADVC110 for the capture and at least while I played its captured video on the PC with VLC interlace disabled... it appeared to play better then the huffyuv avi file so I have faith it will burn to DVD well. So my question is... ¿WTF am I doing wrong with the Pinnacle card?

I read a few things about interlacing filters during capture using VirtualDub but then isn't using filters a fake quality of the video? Perhaps I need to swap fields? I'm a noob into this... Please advice me what to do so when I encode the huffyuv file to DVD I'll see it on the TV as good as the original VHS thanks.

PS. Maybe this note will help... I use a Panasonic AG-1980 VCR whose captured videos unlike the SLV-R1000 allows me to effectively use BOB and other interlacing modes on VLC.

OK, first of all, you're not doing anything wrong, interlacing is very normal when capturing from VHS.

Bob deinterlacing doesn't look good because it's the most basic deinterlacing method, and needs the display to have a refresh rate that is a multiple of the video framerate to look halfway good (for example 100Hz for 25fps).
For good deinterlacing on PC, you may wanna use ffdshow as a decoder and enable the deinterlacing filter (TomsMoComp is a good option).
For DVD playback on PC, you may need an advanced DVD player like PowerDVD which has advanced deinterlacing techniques.

That's not true!
In fact 'bobbing' (framerate doubling) is the only deinterlacing method that preserves all motion in the video :cool:

While "dumb" bobbing filters produce the nasty jump up/down effect (bobbing effect), good bobbing filters can produce great quality.
Some Bobbing filters that are known to give good results are: DGBob, Yadif or KernelBob. Of course there are many more...


BTW: I'd say that 'Skip Field' or even 'Weave' is the most basic deinterlacing method.

alright forget about good or proper interlacing methods for pc video playback! my problem is I'm not getting good huffyuv avi file off the card because something is wrong while capturing, my advc110 avi is perfect but it has lower quality so please help me on the issue.

Nothing is wrong with your huffyuv file I guess.
If you're not getting combing with your advc thing, then it is capturing only one field, which is what you may've been calling "lower quality".

I think the problem is that WMP and other players use the field b first... is there anyway to relabel all fields in the video?
