  1. THe VCD seemed a little blocky when played back on the TV. Could this be a result of using 4:3 NTSC on the Advanced tab in settings on TMPGENC? Is that setting somehow stretching the picture and causing the blockiness? Will VCDs play if the mpeg was made with 1:1 VGA setting in TMPGENC?

    Is there a filter that can reduce blockiness or other lines that appear in video in VirtualDub?

  2. Does 4:3 setting cause blockiness? Hmmm ... maybe you should encode a short clip where blockiness occurred and post your results using 4:3 and then VGA 1:1. It just might make a difference. And I would also like to know.

    Some settings make no difference. For instance, Soften Block noise is completely useless for fast motion blocks. You'd be better off using Motion Blur in Virtual Dub combined with Blend Deinterlacing in Tmpgenc. However the result is kinda dark and blurry. So you gotta increase the brightness in VD too.

    Someone also mentioned changing GOP IBP values to 1,1,1. I haven't tried this yet as my hard drive is currently filled.

  3. The blockiness is a compression artifact that you will have to live with if you want to make VCD's. Only if the source is really good, and you use non-real time compression, can you reduce the blockiness, but not remove them all together. During fast action and high motion, you will see blocks in the video. This is Mpeg compression at work.

  6. VCD is only 1150/sec

    where DVD can go up to 10,000/sec

    plus..VCD is 352x240

    DVD is 720x480

    That's why DVD is so much better..

    More then double the res....
    More then quadruple the bitrate!!

  7. OK, in order to tell you how to make a better encode we need some more info: source (DVD rip, DivX, video capture, etc) and the settings you used to encode.

    You should check the DVD Players list to the left to see if your player will play xVCDs. If you might want to consider uping the resolution to 352x480 or 480x480, set motion search to high, use 2pass VBR, detect scene change off, up bitrate to either full CDR or to DVD players max.

    This assumes good source. A DivX source will is normally not going to make a good x(S)VCD no matter what you do to it. You can't 'improve' the quality. But a DVD rip... you can make an encode of nearly DVD quaility (using 2 80min CDRs for the ave movie).

    Your VCD's are blocky? Perhaps you should read this topic first.
