Audio sync after pulldown.exe

[joshbm]

I have a problem...

I rendered in MSP 6.5 a video file in 23.976p.

Video: 6000 kbps CBR
Audio: 320 kbps CBR

After I rendered it, I ran the MPEG-2 file through pulldown.exe using these parameters:

pulldown SP_cut.m2v newSP.m2v -drop_frame true

Now I thought I'd be ok if I just simply burnt the media. Wrong. The audio is out of sync... What did I do wrong?

PS- I now know it should be:

pulldown SP_cut.m2v newSP.m2v -drop_frame true -prog_seq p -prog_frames p

For progressive frames... I'll try that...

I ran both my audio and video through MuxMan 0.13h. It gave me an error:

Multiplex Operation Halted
---------------------------
Largest GOP of 38 fields exceeds DVD specification of 36. Resulting DVD is non-standard.

I have had the same error when specified 18 frames per GOP encoding 23.976 stream. Obviously after the pulldown they become 19 in some situations. They are "artificial" frames ofcourse but your DVD player will read them as real frames.
So, I encoded again with 12 frames per GOP and the error is gone.
Hope this makes sense.

Makes sense, but how can I specify the desired GOP? Because it does not look like I can within Media Studio Pro 6.5.

Well, I simply didn't understand what is MSP:confused:
I don't know how to specify the GOP in MediaStudio Pro,:) but what I know for sure is that if I get a software for mpeg2 encoding in which I could not set some basic aspects of the video properties (e.g. bitrate, GOP structure, framerate, frame size, encoding type -> interlaced or progressive, scan order, DAR, etc.) I will throw it immediately trough window and try to forget it as soon as possible:D .

When encoding 23.976 for NTSC the typical gop is 12 frames (500ms). You should not exceed 14 as that can exceed the maximum displayed frames (15 x 1.25 = 18.75)

As for the message, it is incorrectly presented as a fatal error, it is only a warning. The multiplex did not abort, and all files are complete.

also prog_seq should be set to interlaced even for progressive material unless you want some dvd players to play back jerky. its been discussed in other threads before.

Thanks guys! The only problem I have is that the process I go through is this:

1) Take DV file and edit it in Media Studio Pro 6.5 (MSP 6.5).

2) After I edit the sound and video the way I want it, I close MSP and move all of my video files I worked with into a new folder. This is to trick MSP into thinking that the video files are gone and need to be relinked. I then copy my original msp file.

3) I usually then make an AviSynth script of my files which were imported in MSP 6.5. Since I have Link2, I make a wrapper AVI file (fake AVI) of my AviSynth script.

4) Open up MSP and since it thinks all the files are gone, I simply redirect it to AVI wrapper file (the AviSynth script).

5) Then from there I can encode with all my changes and such directly to MPEG-2 from MSP 6.5.

By following the steps above, I CANNOT use another MPEG-2 encoder. Unless it opens MSP files or I convert my entire editing over to an AviSynth script. Which is pretty much impossible, since I work with DV Type-I, therefore the audio is not kept with the video file.

If you see my dilemma. Media Studio Pro I suppose outputs edl files, and if there is a edl > avs file converter, I could use it.
