    I encode captured AVI with TMPGEnc to DVD format. I load DVD template in TMPGEnc and change settings: bitrate to CBR 7000, DC Component precision to 10 bits and Motion Precision Search to Highest Quality and despite these settings I get blocky DVD (artifacts) in fast moving objects in some scenes.
    Is it normal and if isn't how to solve this blockiness? I tried to encode in half DVD (352x576) format and I get blocks, also.
    Thanks...

    Stile,

    I think you left out that your (captured) source is divX that you D/L'd from
    the net. I could be wrong. But, if I'm not, then there is NOTHING you
    can do to rid those blocks. If it is divX, then you made the mistake of
    re-encoding someone else's encode (and quite posibly a re-encode) from
    a lower resolution to begin with ie, 640x272, 352x240 or 320x240 etc.
    before I get hammered, I left out. . . it's not, divX is bad. It's not. But,
    that someone (or yourself) could have encoded the divX poorly, OR, your
    settings for divX was no match for your PC spec.

    If it's a divX source, then look closely at it to see if there are any blocls.
    chanses are, there are, but in any case, if it is divX, your player may not
    be showing you the blocks for obvisous reasons, like it's not playing it
    full screen or is playing full screen, but in any case, TMPG WILL pick up
    ANY artifacts during the encoding, NO MATTER HOW HIGH YOU TURN UP
    THE BITRATE and/or HOW HIGH YOU RASE THE RESOLUTION.
    If the blocks are there, TMPG will pick them up - that's for ANY type of
    source, divX or AVI or MJPEG etc.

    If your source is NOT divX, then you may have some really FAST scenes
    to be showing blocks at 7000, OR, if you actually DID do the capturing
    yourself, and to divX?? you probably had many frame drops. But, that
    shouldn't be causing you any blocks I don't think. Else, you didn't use
    sufficiant settings in your divX codec settings prior to capturing in it.
    * Is your PC up to par for divX?? Probably not.

    But, I see you have a Pioneer DVD player. Perhaps, all it really is, is your
    Pioneer brand after all.
    See if you can play your sample clip in some other brand player, like a
    friends player.

    Can anyone confirm this?
    Later.

    No, it is not DivX. Captured AVI is from my VHS tape. Can the problem be in some invisible noise that TMPGEnc encode and that this noise make the blocks?

    Could Be A Number of things Just By the Information you Provided as of now.


    1. You Didnt De-Interlace the Video
    2. VHS Standard is 640x240 (640x250 MAX) And You Just Stretched it to 720x480

    3. I Believe Most VHS Movies Use 23.97 NTSC FIlm and Not telecined (29.97 Which Is What the DVD Template Uses)

    My Reccemended Settings..

    Type : MPEG-2
    Video Resolution: 640x240
    Bitrate (Video) : 3- 5 Mbit VBR or CBR some where in Between
    Bitrate (Audio) : 224
    Frame Rate : 23.97 for NTSC Film or 29.97 ofr NTSC TeleCined
    Encode Mode : Non INterlace for 23.97 or Interlace if the Video On the Tape is at 29.97
    Video Source Type: Non INterlaced if its NTSC Film. or Interlaced if its NTSC Telecined ... Which Really unless your Going over XXX x 480 you Shouldnt Have to De-interlace.

    GOP Structure: 1,5,2 is Defualt and Reccemended By most But i Use 2,2,2 AS its More Frame Stable.

    Out Put Interval : 1

    and Check the Detect Scene Changes Box.

    try That..
    the Rest of your settings look fine.

    --Edit.. Also Computer Monitors Wern't Buitl to Be Interlaced, so interlaced Video has Side Effects (Artifacts, Horizontal Stretching etc, Also if you did De-Interlace, Certain Methods have their Own Side Effects. )

    Tnanks Digital-Overload, but I am using PAL system because I am in Europe, so:

    1. Why should I de-interlace video? I want interlaced video (looks better).
    2. May be that I streched the video.
    3. PAL VHS is 25 fps and 25 fps is in the template so this is not the problem.

    That's all what I can tell...

    Oh ,, I Didnt Know It Was PAL.

    Pal is 720x572 for DVD.

    Yeah Noise Reduction is Worth a try.. also try Using the "Soften Block Noise" Filter.. Under Quantize Martix tab.
