  1. Having just got a LG GSA4040B DVD burner, (which I must say appears to be extremely good), I have burned a few movies after converting from avi.
    All movies so far have been XviD with AC3 audio, and 23.976 FPS.

    I have been using the conversion guide from this site titled: -

    How to convert AVI-DivX-XviD with AC3 to DVD with AC3.
    https://www.videohelp.com/forum/userguides/186739.php

    Picture quality comes out superb, as does audio quality, and there are no audio/video sync problems.

    The resultant DVD's do however have some jitter every few seconds. This I can best describe looks like some frames are being jumped, but audio stays in sync. I have used both Nero, and TMPGEnc DVD Author to burn, with the same results.

    All I can think of is that there is something in the process I am using to encode or author, which is causing this jitter.
    I am following the above guide to the letter.

    Any help with this appreciated.

  2. are you experiencing this jitter in both your set-top dvd player and on your computer?

  3. Yes!
    I am seeing this on both.

    After reading some more in these forums, it appears that the answer may be to frameserve. I will try this on the next movie I encode. I still do not understand why frameserving would/will make the video better, other than it serves the frames to software such as TMPGEnc at more of a controlled rate which TMPGEnc cannot do itself.

    If there may be another way to remove this 'jitter', please feel free to enlighten me.
    Until I got this DVD burner, I had been making VCD's, which have always gone well. So I am new to encoding and authoring DVD's, which I now see is both similar and very different at the same time.

    Thanks again for any help.

  4. After some more reading, could the jitter be caused by using the DVD (ntsc).mcf template for a 23.976 FPS movie, which TMPGEnc is encoding to 29.97 FPS?

    Is there a 'film' option anywhere for DVD, as there is for SVCD and VCD?
    I can't see one in TMPGEnc.

  5. I am having the same problem (my post is further down), at the moment I am encoding the movie using 2pass to see if it gets any better. If you want to try encoding it at 23.976 you could try loading the unlock template and then setting everything manually so that you can choose 23.976 fps without the 29fps uplift.
    If my way works I will let you know but it does take twice as long to do it so I won't know for another 6 hours if it has worked. At the moment my movies are coming out just short of 4gig so whether the 2 pass will take it over the limit only time will tell

    Although following the steps here, up until the tmpgenc settings seems the best course (setting that up everytime as well would prove to be a pain in the butt but what else is there?)

  6. If anything the 2 pass made it worse I am going to try frameserving with virtuadub, if you havn't already done the same I will let you know how this one turns out

  7. I saw that one but I couldn't find it again Thanks for finding it but that is the guide I was following anyway. The frameserve worked beautifully and it took no time at all to set up, So therein lies the answer...and in the tmpgenc stickey at the top of this forum where I should have looked in the first place
