PAL/NTSC on same DVD?

[boing]

First of all, would I be correct in thinking that if I convert a 29 fps Xvid to a PAL DVD compliant mpg it could produce a final mpg with more defects (jerky look to picture etc) than if I had converted it to an NTSC DVD compliant mpg?

If this is the case, is it possible to mix NTSC and PAL on the same DVD?

Or are the jerky qualities of the final DVD compliant mpg down to the fact I am going from avi/divx/Xvid back to DVD mpg?

Would this explain why some avi/divx/Xvid to DVD mpg encodes result in a smooth film, but others have the jerky quality?

In short: if the original avi/divx/Xvid is PAL should I covert it to PAL DVD mpg?

Hmm, I have just performed a quick test and converted a 29fps Xvid to a 29fsp NTSC DVD mpg and the resultant file has none of the jerky motion of the earlier file (same Xvid as above)after I encoded to PAL DVD mpg

Aw man, please tell me that as long as the files are DVD comliant and that GUI for DVD author is set to 'PAL' that I can import both NTSC and PAL mpgs into GUI for DVD author and create my PAL DVD

technically, no. Mixing PAL and NTSC is not compliant. Most authoring software won't let you do it, and not all players will play it if you do. You could try using DVDPatcher to patch the resolution and framerate to fool the authoring tool, then change it back again later.

edit : just re-read your post. There is no nice way to convert 29.97 fps source to 25 fps. You have to either blend or shed frames, and this will give artifacts or jerkiness. If you have mixed source you are better off changing the PAL source to NTSC (much easier) and creating an NTSC disc.

Gunslinger, would going from 25fps to 29fps as you suggest give rise to any 'jerky type' flaws?

If not, then as you say, that would be the easier option, to wit, could you tell me whether most set top DVD players in Europe would accomodate NTSC disks without hassle?

Thanks for your help

The secret of smooth PAL to NTSC conversion is to use the pulldown method documented and discussed here : https://forum.videohelp.com/viewtopic.php?t=300144

As for playback - pretty much all PAL players will play back NTSC disc either natively or through conversion to PAL or PAL60

Thanks again, that seems to have cracked it

Just for the record....DVDShrink will create a PAL and NTSC disc but of course you will have no menu.
