tmpgenc encoding prob's

    Hey guys/gals, anyone have any ideas as to why some dvd rip/encoding has a jerky appearance when panning/fast movement scenes are played??

    I'm using smart ripper, then dvd2avi, then tmpgenc for the encoding. After using tmpgenc, I find that some movies turn out fine, while others have a jerkiness as if the frames per secound is incorect on panning sections only.

    I have tried all setting in tmpgenc with no luck. I could be wrong here, but I think it may have something to do with dvd's that are in progressive format??

    Any help would be appreciated. :))

    Sounds like the field order settings for the source video in tmpgenc is wrong. Try using the 'wizzard' in tmpgenc. It analyses the source video and figures out the field order.

    G'day jnihil
    Thanx for the response, yes I have tried the wizard as well as changing the field order. Still no good, when tmpenc encodes it appears to do it in chuncks of approx 18 frames.

    Could that be why it appears jerky? I have tried all the templates, I have tried it with all unnessacary appz shut down, I have tried with different versions of tmpgenc.

    I use smart ripper, then dvd2avi. Could it be a setting dvd2avi? I use the same programs and settings to convert dvd to svcd, however some work fine and others are jerky. I am in Australia so obviously I am using PAL.

    If I use dvd2vcd everything works fine, however the process takes a lot longer.

    Mmmm... kinda hard to say exactly without actually seeing the video, but the 'chunks of 18 frames or so' is probably due to the GOP structure.

    I never had the need to fiddle with the default settings for dvd2avi so not really sure if that would have any such effects on the resulting video stream, but perhaps you could use VFAPIconv to convert the dvd2avi project to a pseudo-avi and see if that has the jerky-ness you are seeing.

    Rgds,

    Heya Jnihil, thanx again for the reply. :))

    Recently I copied 2 dvd's,Final Fantasy which worked perfectly and O'Brother Where Art Thou which had the jerky frames.

    Final Fantasy was Interlaced, while O'brother was progressive, apart from that all settings were identical for all programs.

    I redid both movies just to compare frames etc, Tmpgenc ran approx 18fps on both, so it shouldn't be that, however when I replayed both movies after Tmpgenc was finished they both appeared jerky??

    However, when burn't using nero Final Fantasy was fine, O'Brother was still jerky??

    Some of the advice I've seen says not to turn "dic at once" off in nero??

    Could it be nero for some odd reason??

    Regards Shintaro

    I did have an issue with the PAL version of 'Barbarella' which CCE would always create jerky videos, just like what you would see with wrong field-order. Instead of spending days trying to figure out the cause I trancoded using REMPEG2. It did it flawlessly.

    Not much of a help I know, but you may wanna give it a go if you want a short-cut.

    Hmmmmm, just encoded Shrek for the kids, same old problem. Very annoying, it is only a problem when the camera does a panning shot, U know when the camera sweeps from left to right say. It is ok if the camera stays still and the actors move. DVD2SVCD seems to work ok, however, U have less control using it, not to mention sometimes DVD2SVCD locks up during CCE encoding, usually around 94%.

    Might be easier to buy the movies. lmao :))
