framerate problem

[Yonith]

I used dvd2svcd to make a video file but when i try to load it into my dvd authoring program it says the framerate is too low @ 23.97. The avi is an XVID with that framerate and it looks fine. With the last dvd i made i set dvd2svcd to make no dvd image and put the sound file and mpv file in the dvd authoring program and it came out perfect. The dvd authoring program im using is TMPGEnc Dvd Author 1.6. I looked at the mpg that was made bbMPEG_Muxed_File00.mpg and it was very choppy. I figured it was becasue that file was choppy that Encoded_Video_TMPGEnc_NTSC.mpv was refused by dvd author. Im not really sure other information is needed but my basic questions are 1)the mpv goes in the dvd authoring program right? 2) does that mpg mentioned above being choppy mean the mpv is chopppy too? 3)if the answer to 2 is no then how do i make the program think it's the proper framerate?

1) Yes and no :p
You should be able to author using either the muxed file - ie bbMPEG_Muxed_File00.mpg, Or by putting the mpv and audio files into TMPG DVDA as you suggest. However, if your source is 23.976fps, DVD2SVCD performs something called pulldown on it to make the file DVD compliant.
There should be another mpv file called Pulldown_Encoded_Video_TMPGEnc_NTSC.mpv - use this one for authoring purposes.

2) Possibly :rolleyes: Author as above and play in your software DVD player before you waste a disc. If it the authored DVD files play back choppy, have a look in the sticky on "AVI2*** fails (at some point)" at the top of the forum. There is advice on editing one of the .ini files which should correct choppy playback. It will mean reencoding from scratch though :(

3) answered already

Hope this helps and welcome to the forum!

I may be wrong re. pulldown - TMPGEnc has its own pulldown which I think DVD2SVCD uses if TMPGEnc is used as the encoder. Try using the muxed file to author for starters and see what happens

I noticed that there's a correlation between me having problems and with the video being xvid. I seem to remember reading something about how that could be a problem so I'll just search around for the answer.

I checked out that sticky, and it solved the framerate problem but created another. Now my audio is out of sync. I tried following the procedure with virtual dub but I get the following error message:

virtualdub has detected an improper VBR audio encoding in the source avi file and will rewrite the audio header with standard CBR values during processing for better compatibility. This may introduce up to 119865 ms of skew from the video stream. If this is unacceptable, decompress the *entire* audio stream to an uncompressed WAV file and recompress with a constant bitrate encoder. (bitrate: 125.7 +- 48.9 kbps)

I proceded to go ahead anyway and of course the avi's audio was out of sync. So now I'm basically getting the idea that with this particular avi I'm going to have to use something other than dvd2svcd. Is there any way I can fix this and still use dvd2svcd?

Ah. I've updated that sticky to use VDubMod.
This actually gives you the option of not rewriting the header in these instances.
It pretty much invariably does more harm than good.
