PAL to NTSC Problem

[bigslava]

I re-encoded my PAL movie with TMPGEnc using DVD NTSC
Presets. The picture is good, but movement is not smooth.
Picture is jerking. Can anybody help with that?

Thank you for your help.

I have had good results with TPMGplus providing I did the following:-
1) Deliberately set the bit rate about 15-20%lower than usual.
2) Use VBR - 2 pass
3) Search precision - highest quality - very slow
4) Arrange - full screen keep aspect ratio
5)Lastly split your movies up into smnall segments and batch them, occasionally TPMG crashes doing this and it is a pity to lose the whole thing.
6)Finally it worked best for me when I started from apple movie format.
7)This takes a long time! 1 hour has taken me over 3 days with a 600htz, 1 GB ram PC

What is this apple movie format?

To answer your question Go to www.apple.com and the quick time section. It is a system of movie files that was developed by apple that works well with DV. Many other products are based upon this technology.

Secondly you may wish to go to

and try out the NTSC PAL video convesrion software that they have there. I have not tried it yet but it sounds good.

bigslava, what is your source material format. If it is avi, do the following:

Open in vdub and set frame rate to 23.976 fps, save out a copy using direct stream copy, no audio.
Still in vdub Extract the audio to a seperate wav file.

Open this wav file in goldwave (or your another audio editor such as soundforge) and use the time change/stretch/shrink option (forget exactly what its called at the mo and at work so can't check) to change the length of the wav to match that of the new avi.

Now encode with TMpGenc to video only (movie.m2v), DVD NTSC template except framerate 23.97fps. Use pulldown.exe on this m2v file to change framerate to 29.97.

You can now use this wav and m2v file to author your dvd. Depending on the authoring app you may want to encode the audio from the wav to mp2 and you may want/need to multiplex them.

This should give a smooth playing result.

Hope this helps.

The above works well - I so the same thing converting my PAL avi's to NTSC. Only difference is that I found I have to de-interlace the NTSC avi before encoding to MPG (using TMPG and applying the 3:2 pulldown on playback). Did this because for some reason I got an occassional stutter when playing back on stand-alone dvd players, especially during relatively fast motion scenes.
