How do you do your PAL2NTSC conversions then?
I use TPMGenc. You'd do a conversion from 25fps to 23.976 which has more of an effect visually than on the audio.
You're doubling frames to keep up with the correct speed.
The audio is totally fine.
Well that's why your getting artefacts then. TMPGenc isn't what you should be using if you want a high quality PAL2NTSC conversion. you should be adding any frames whatsoever and that's why it'll look bad. you want to manually change the framerrate in the files information only. no adding of frames. If i do a NTSC2PAL or a PAL2NTSC this is how i do it:
rip the DVD to one large file (no file splitting) using dvddecrypter. demux the audio & video seperately using the stream processing tab. make sure you select "demux" for each stream you want to rip separately . then load the VOB into virtualdubMod. then go to the "video>framerate" settings. change the framerate to 23.976 in these 2 sections: "source rate adjustment> click on "change to.." enter 23.976 then in "framerate conversion" click on "convert to fps" and again enter 23.976. now click on OK and close the box. Next got to "video>filters." ad the Resize filter. change the width to 720 and the height to 480 and filter mode needs to be changed to Lanczos3. now again click OK. now select your compression in the "video>compression section. i always use lagaryth lossless codec because its a lossless codec. it does produce a large file but you lose no quality whatsoever. now export the video. once this is done use a high quality Mpeg encoder like Procoder or CCE as these are the best out there.Remember to add the 2:3 pulldown when encoding for NTSC
to change the speed of your audio just load the AC3 file into Besweet , change the framerate from 25fps to 23.976 and export your audio to ac3. you get an almost exact copy and it plays at the correct NTSC speed. Now just load your new MPEG" & AC3 file into a DVD authoring program. Add your chapters and create a new DVD. you'll see that this way may be longer but the results produce a DVD that is almost the exact same quality as the original(if you are doing it do a DVD-5). if you are going to be adding it to a DVD-9 then the quality is as good as the original. no artefacts whatsoever if you ahve done all the steps correctly. in fact using a PAL DVD as a source for an NTSC conversion will probably give you better results than the actual NTSC DVD because this way it retains most of the detail of a PAL encode
Using TMPGenc to do a PAL2NTSC conversion is almost as bad as using a 1click program to do it. You can't expect to take short cuts and get quality results
