NTSC to svcd, correct frame rate and encode mode in TMPGenc?

[NitraMus]

I have ripped a DVD and I know that it is in NTSC. What I want to know is what is the frame rate and if it is interlaced or not or .... All the rest I don't have any problem.

Is there a way to know the frame rate of a original NTSC DVD or is all the same thing?

I have the DVD that I ripped trying to put in MPEG-2/SVCD. I am using TMPGenc and dvd2avi. In DVD2AVI, should I "Force film" and then put the frame rate to 23.97 FPS in TMPGenc or do not force film and then put the frame rate to 29.97 FPS. Then what encode mode should I take. I read in different places that I should take interlaced and 3:2 pull down when playback.

What are the best settings or what should I do to get a MPEG-2 as close a possible as the original.
Keep in mind that I don't know the frame rate and the encode mode of the original NTSC DVD.

Thanks

If you use the TMPG wizard, and select NTSC SVCD as your output, then you shouldn't have any issues. TMPG will correctly interpret the input fake AVI.

ALL MPEG2's are interlaced (KVCD/SVCD/DVD), leave that alone.

Most DVD's are 23.97 fps film. It doesn't really matter if you encode at 23.97 or 29.97, other than you can get a better bitrate at 23.97 , but 29.97 'looks' smoother on some players.

The problem is the last time that I left the default alone in the templace the audio and video was not in synch. The default is 23.976 fps (internally 29.97fps). With DVD2AVI i did not "Force film" so the bite rate is 29.97 fps. I still have the rip so I can still go back and "force film".

DVD2AVI will tell you while it's reading the file in
the statistics window what it thinks the video is
If it's mostly FILM then you want 23.976
otherwise 29.97


All MPEG2s are NOT interlaced. Most Commercial DVDs are NTSC FILM
which is progressive 23.976 with soft pulldown.

Keep in mind also that in SVCD (or vcd for that matter) the sample rate of the audio needs to be at 44.1 khz. If you're audio is at 48 khz (which is standard on DVD) the software wil "slow" the audio down to 44.1 which will give an out of sync. You need to resample your audio to 44.1 and then either feed it in tmpenc during encoding or mux it at the end.

The preview pane of DVD2AVI will answer most of your questions, as is covered in several of the guides to the left.

Gazorgan, what have you been smoking? Not only are most DVD's NOT interlaced, but it DOES make a major difference what framerate you use. If the preview shows 23.97, then you use that as your source framerate, and then use pulldown.exe to insert the flag. (you could use TMPGenc's built-in function, but some seem to have problems with playback while pulldown.exe works). This save's 20% (variable) off your filesize.

As to audio, I would leave at 48k, if your player will handle it. Most will, and if you ever intend to convert them to DVD you'll be ready to go. Even more so at 352x480.

Most dvd's are 23.97fps, but I have had nothing but trouble when I try encoding with tmpgenc at that rate (this is after force film on dvd2avi). 50% of my movies get the audio out of sync. However, when I use dvd2svcd and cinema craft encoder, 23.97fps works fine. But if you take a movie and encode it at 29.97fps, it will turn out just fine (as long as you don't use force film in dvd2avi). I actually like the quality better (it is not as 'grainy' as 23.97). It does, however, take longer to encode, but I have never had a movie fail me doing it that way. http://entiendo.gotnet.net
