I have been encoding for about three months now, and have done over 40 PAL movies. My first NTSC movie (29.97 FPS), and while the movie turned out, I get lines in some parts of the movie (don't sugest interlacing as it has already been rulled out), and also some parts of the movie (motion sequences) are jurky. It is not jurky as in not enough CPU power, but as in it looks smoth untill you look closer and it seems to jurk, then be smooth, then jurk, then be smooth. This is not a problem in Still shots. The problem is really evident in panning and zooming sequences. Does anyone know what I did wrong?

The problem is caused from the Progressive format of the DVD. It is not a constant Frame rate. If you are using flaskMpeg or XMpeg this is definately the problem. I recommend using DVD2AVI and running a forced film out put http://www.doom9.org/mpg/images/dvd2avi-options.gif (<~Click for Image). (Simply checking deinterlace with the DivX 4 codec doesn't help). What forced film does is captures at 23.976 fps rather than the actual 29.976 fps. This in turn removes the frames that are defective. To learn more on using DVD2AVI read the"DVD2AVI Guide" (http://nickyguides.digital-digest.com/DVD2AVI.htm) from Nickys Digital Solutions Page!

"Quoted from Nicky's Digital Soulutions Page"

"I'm not very experianced with NTSC movies because most of mine are PAL. But after with the ones I've tried recently I suggest you always try and use the force FILM option, go to: Video > Field Operation > Forced FILM. If it works you will not have that horrible combing effect from an interlaced video. Not sure what interlaced video is? Check my guide Here. If it doesn't work, you will know soon enough when you open it to check. Make sure you check action scenes or those with lots of motion."

If you really want a high quality rip I would use Gordon Knot. You can Download it and read the complete Guides on how to use it. The quality achieved is the best possible when you use Gordon Knot. Check out the guide and download Gordon Knot from Doom 9's Guide on GKnot. (http://www.doom9.org/gknot-main2.htm) All you need to download is the GKnot full installer (http://www.doom9.org/Soft21/Files/Encoders/GordianKnot.0.21.Setup.exe) and your ready to go. It includes all the software; The Ripper (Smart ripper, Vstrip), DVD2AVI, Virtual Dub and Nan Dub. Also for the audio AZID and LAME + GUI. I definately reccommend it, want another opinion? Ask someone in the GKnot Forums (http://rilanparty.com/vbb/forumdisplay.php?s=&forumid=28) if they would use anything else to encode. This is also a good place to ask questions if you run into trouble with Gordon Knot.

Good Luck
