    Hi,

    I encoded an animated segment ripped from a DVD to SVCD using TMPGEnc. All standard SVCD 1.0 settings of 480 x 480 and CBR 2500. As far as I can tell this is the highest bitrate for a standard SVCD. Motion search also set to the highest quality.

    When viewing the output on the DVD player, there is very noticeable video noise where there is a alot of motion or big (almost entire screen) objects moving.

    I was wondering if this is normal for SVCD, which after all I do not expect to match the quality of the original DVD, or did I get an inferior result.

    Comments appreciated. How do your SVCD handle rapic multi-directional motion or large detailed moving objects?

    THanks,
    Haris

    Well My SVCD"s made from DVD"s allways Turned out Great ..They had no Blocks or Jumpyness and the Quality was allmost as good as the Original DVD....How did you encode this sequence with Tmpgenc?? Did you Just load the Vob file directly into Tmpgenc or did you do it the Proper way by useing DVD2AVI to Frameserve to Tmpgenc?? You Might also Try useing CCE to encode as It has allways produced much better Quality at lower Bitrates for me and it is up to 10 times as Fast as Tmpgenc....

    Thanks for your reply.

    I neglected to mention that I did use DVD2AVI as the frame server along with Toolame and some other plug-in as found in the guides. I also used VCDEasy to burn the SVCD. Using Nero 6.0 burns smaller files without any appreciable quality difference as far as I am concerned.

    I also was not clear in the description above. There actually are two separate issues:

    1. When the picture is panning slowly there is "jumpiness" where the frame seems to get stuck for just a fraction of a second and then catches up to the movie. It does not happen when the frame moves fast enough.

    2. Blocks appear when most of the screen is moving very fast and especially when there are multiple relatively small objects that move in different directions.

    Anybody else? I would love more input before I decide that it is my DVD that is misbehaving. BTW, I am using a Sony 655 5-disk carusel player.

    Well the Jumpyness you are Talking about sounds like Interlaceing Artifacts...When you Used DVD2AVI did you notice if the DVD was from a Film source or From an NTSC Source??? Most DVD"s are From a Film source so you have to use the "Forced Film" option in DVD2AVI, then you Encode the D2V File useing the "23.976fps(29.97fps Internally)" Frame Rate setting and with the 3:2 Pulldown Setting enabled..This will get rid of the Interlaceing artifacts and this is How you are Supposed to encode DVD"s From a Film source...If it turns out the the DVD is In Pure Interlaced NTSC then you should use the "Deinterlace" filter in the Advanced settings, you would Probably use the "Even field" filter...The interlace artifacts were Probably why you were haveing Problems...If you try it this way you should get much better results...Cheers
