TMPGEnc DVD Author won't do 23.976 fps

[wallywalters]

I have several 23.976 fps MPEG-1 video clips (NTSC) that I'd like to burn to DVD-R, but TMPGEnc DVD author won't let me. (The audio is 48 kHz). Is there any way I can get around this without converting the already low-quality video again -- or are there any other authoring programs that WILL handle these files?

Many thanks.

You can demux the audio and video, and then use IFOEdit to create VOB files, which you can then burn.

[wallywalters]

Thanks very much. I'll learn me that IFOEdit tonight.

Is there any way to use IFOEdit to author DVDs with multiple clips/ I can't find any provision for making a Main Menu.

be warned that most dvd players will not play an ntsc dvd with a frame rate of 23.97 correctly as its not truly a dvd spec, for ntsc that is. Although the irony of it being that an svcd is "essentially" a raw dvd clip and for that it works fine

Really ?

NTSC (NTSC Film)
Video:
Up to 9.8 Mbit/sec MPEG2 or up to 1.856 MBit/sec MPEG1 video
720 x 480 pixels MPEG2
704 x 480 pixels MPEG2
352 x 480 pixels MPEG2 (Same as the CVD Standard)
352 x 240 pixels MPEG2
352 x 240 pixels MPEG1 (Same as the VCD Standard)
29,97 frames/second
24 frames/second with 3:2 pulldown (NTSC Film, this is only supported by MPEG2 video)

Your MPEG1 files should be 24fps, not 23.976. Try changing the framerate and see if it imports then.

[mazinz]

yes ntsc film works fine for svcd but does not work right for a regular dvd. This why most author programs (actually with the exception of perhaps ifoedit) will not accept a clip with that frameate nor most encoders give the ntsc film template for dvd (but it does give it fine for an svcd)

Why don't you re-encode your MpEG1 to MPEG2 and
apply pulldown to make it 29.97 ?

[sammie]

Really? I did one last night. Just run pulldown on it and it will be fine. 23.976 is a standard rate if you have pulldown set.

[mazinz]

when you use pulldown your basically still telling the encoder to make the framerate run at a differnt speed other than what the current framerate for your clip is

There seems to be alot of confusion in this thread.

The DVD standard most certainly supports 23.976fps if the video is mpeg2 and has 2:3 pulldown flags embedded in the stream. These flags instruct the dvd player to telecine the video to 29.97fps as it plays. The vast majority of commercial NTSC DVDs are in fact encoded at 23.976fps with pulldown flags.

The DVD standard does NOT support mpeg1 video encoded at 23.976fps. Mpeg1 is only supported in the DVD standard if encoded at 29.97fps. Pulldown flags do NOT work on mpeg1 video under any circumstances. If you use pulldown.exe on an mpeg1 stream it changes the file header to mpeg2 so who knows how it will be played back.

The only format (with hardware support) which accepts mpeg1 video at 23.976fps is VCD.

So your options are to telecine the video to 29.97fps yourself, or to encode to mpeg2 and apply 2:3 pulldown flags. If you are set on making this into a DVD then the latter option would be higher quality, but both require a re-encode which will lower quality. If you want to maintain the best quality possible, and these files are already VCD compliant, then you would be best off just making them VCDs.
