I have a divx with framerate 23.975.
What I have to do for to make a kdvd?

thanks

Just add a "assumeFPS(23.976)" at the end of the script and encode it into MPEG2 with 3:2 pulldown activated.

Don't bother with the audio, the diff between 23.976 and 23.975 is so little that you won't notice the lack of synch (something like 0.02 second per hour of movie).

thanks, phil.
in the meantime, I have made some search and some test.
I have taken a piece of file that is 5 minutes.
I have used assumefps(25.000) after the line avisource, for the audio instead I have used beesweet changing the frame rate from 23.975 to 25.000.
I have imported all in dvdlab, I have compiled the dvd and I have tested all and seems to work.
In particular phil, what is the difference between the procedure that I have exposed and that one that you have suggested to me.

thanks again.

edited:
when active 3:2 pulldown the button "settings" is activated . If I click on it one is opened window with all one series of options to me completely disowned.
I have to set something there?

In an other thread I have read that incredible it suggested to use:

So in case of progressive pal to progressive ntsc do this:

in the opposite case I think that can be used:

AssumeFPS(25.000)
TimeStretch(tempo=(100.0*25.000)/23.975)

I would want to know if it is possible to use this instruction in order to elaborate the audio in avisynth.

Mainly you converted in PAL when I told you a way to keep the video in NTSC.

If your stanadlone (and TV set) support the NTSC, keep this format; You will encode in 23.976 fps at 480*480 (for instance) insteed of 25 fps at 480*576. You can easily understand that the encoder will have far less data to compress, and then the CQ will be far better. A movie encoded in PAL a CQ70 will be done in NTSC at CQ neard 80.

ok phil, I have understood.
Now I will make a test in order to see if mine standalone and tv set supports ntsc. (if I watch on the booklet of the instructions peraphs I can resolve the question).
by

ok, It seems that all my standalone, and tv set are compatible with format NTSC!

Remenber that I am making a test with a 5 min. file.
now, i would to know:

1. When I import the stream video in dvd-lab, it ask to me of Enable 2:3 pulldown, I think that I did to make it.

In the windows asset I can see the stream with FPS= 29.97 and the TIME is 04:31

2. When I import the stream audio (that is 5 minutes long), it's don't egual with the time of the stream video (4:31).

What I to have to do?

by

someone can help me?

I didn't understand what you did. Did you encode the movie in MPEG2 with "3:2 pulldown while playback" as encode mode in tmpgenc ?

If yes, the audio should be the same length than the video (and both should have the length of your source).

I suggest you do redo all step carefully because something went wrong with no reason.

For encoder I don't use tmpgenc, I use CCE.

So you did badly the "'pulldown" operation. You must use "pulldown.exe" for that, did you ?
If you use "DopulldownGUI", you have to check the box "no pulldown" (don't ask me hy you must check it as you want to do pulldown ).

Try all options until you have audio length = video length = source length (more or less).

ok, I have ri-did all the procedure:
1. assumefps(23.976) to the end of the script.
2. When I import in dvd-lab comes asked to make the pulldown to me. Now the time is visualized correctly,
probably before mistook something in making .mpv

The pulldown change the framerate from 23.976 to 29.97?


thanks.
by

Not really.
The video is still in 23.976 progressive but it will be played by the standalone in 29.970 interlaced.
So, virtually, the video is 29.970 (that is the only NTSC fps allowed on a DVD).

with regard to the audio I have to proceed as usual?
that is I extract the file .wav from the avi and then I make the mp2?

by

Yes.
Just check after the muxign that the audio is in synch at the end of the video.

I know this might be a stupid question but I can only see the box next to 3:2 pulldown intmpgenc. Not the "3:2 pulldown while playback" where do I find this?

You are in the wrong place : the box you are talking about is in the "advanced" tab of the settings. This one MUST'NT be used (never).
The correct setting is in the tab "Video". The "Stream Type" must be "mpeg2", and then for "Encode mode" you can select "3:2 pulldown when playback".

thankyou very much for your advice Dialhot. SHould I leave DC as 9? and are there any other changes I need to make to tmpgenc beofre I start encoding?

The general recommendation is to set it at 8 but I use to encode also with 9. And for the others settings, it depends on your goal ! But I don't see why you should change what you have already for your others KVCD. It is not the first one you are doing.

I muxed as a mpeg1 non-std but when I load it into the tmpgencdvd it says GOP is too long. I didn't make any alterations to the GOP. What changes do I need to make? By the way it worked fine.. the sound was in sync with the movie

Tmgenc DVD Author is too strong on the specifications and very often refuses a stream even if it should not. You should try with DVDLab Pro.

But are you sure of the lenght of your GOP ? As you do so much things without even knowing what you are doing.

Note: to do a DVD you don't to mux ! Give the elementary streams (audio and video) to the software and let it mux them in DVD mode.
(DVDs use a special muxing mode).
