    I'm converting my old VHS collection to DVD, but I'm hitting a snag.

    First of, is there a filter anywhere for VDub, that will let me filter out some of the line noise, other than the capture noise filter? Should I use something else to capture?

    Also, for resolution, does anyone have experience with the best resolution for this? I can capture in any of the supported DVD resolutions, but of course, my source is only 352x240. I should note, that I have a widescreen HTDV, so flaws are very apparent. Even the difference between a 352x240 broadcast (cable) signal, and a CVD/SVCD is striking.

    Last but not least, I'm experiencing syc problems. The original capture goes fine. The audio is in sync, no problem. When I encode, for some reason, the audio is getting progressively out of sync the farther into the movie I get. I can't determine the cause for this.

    Capture via the WDM drive using Virtual Dub to AVI (huffy codec)
    Resolution 720x480
    Audio: 48Khz 192 (187?) Kb/s (give or take..can't remember the kbs, not that it's important)

    Tried encoding using CCE. End up with MPA, and M2V file. When multiplexed, they are out of sync by maybe half a second or more at the end of the movie.
    Any suggestions?

    I too have a HDTV widescreen. I cap at 720x480.


    Personal setting for Vdub noise resuction...

    level ( 16,1.0,235/16,235 ) / Cropping 16top, 16bottom # this helps restore baseline white and black level, you may need to futs with the first three values based on your source.
    2d optimized cleaner 0.9 ( threshold 6 x,y of 1 or 2 each, interlaced ) # Helps restore continus tone areas
    kNRC ( noise reduction to taste 4,10 seem to work well ) # temporal stabilizer
    resize ( 720,448 percise bilinear, letterbox 720,480 )
    or
    resize ( 720,448 percise bilinear, letterbox 720,480 )

    I find it cleans up the image nicely, leaves a little grain, but it's bettern than the noise that is there most of the time. I get 6-7 FPS for this filter on a pIII 700.

  3. DJRumpy,

    I don't know what source you are using that is only 352x240, but if you are concerned about quality on a WS HDTV, why not keep it at 720x480 when you make your DVD? Without resizing, this should speed up your encode. Plus, you won't be compromising your video any.

    Personally, I resize to CVD's 352x480 and am happy with the results. I do notice a difference between the original 720x480 capture and the 352x480 CVD, but not much.

    Can't help with your sync problem.

    Thanks Guys. Snowmoon, I'm assuming the filters you listed are for virtual dub. Are they built in, or custom filters. If they are custom filters, can you direct me to where you downloaded them?

    I was worried that stretching my source to 720x480 would introduce too many artifacts, as it looks grainy enough already, but from your input, it appears that is unavoidable for the most part.

    Custom....

    Under HOSTED

    2d optimized cleaner ( make sure only un unzip the appropriate filter for you CPU it will crash if you are unlucky otherwise )
    Noise reduction/cropping filter = kNRC
