converting DVD to DPG for Nintendo DS

[locutus99]

Hi All,

I'm trying to convert a DVD (NTSC type) to a DPG file for my kids Nintendo DSI

I'm using DGindex to de-mux the audio and then an AVISynth script... Then passing it to xillisoft DPG converter (it seems to be one of the few that can make DPG version 3 & 4 formats which play nicely under moonshell on the DS).

Doesn't matter what I do, the audio is out of sync. Seems to get worse as the movie goes on.

I think it has something to do with the frame-rate set in xillisoft, but I'm not certain. A DPG4 type uses 24 fps, and an DPG3 type uses 20 fps.

As I understand, an NTSC DVD (ripped)should be at 23.976 fps

Can anyone advise what I might need do to get the video & audio in sync??

here's the AVIsynth script I'm using:

------------------------------------------------------------------------------------------
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\DGDecode.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\NicAudio.dll")

# Set size in DPG converter as 256 x 192

vidfile = "test.d2v"
sndfile = "test T01 3_2ch 448Kbps DELAY 0ms.ac3"

video=MPEG2Source(vidfile)
audio=NicAC3source(sndfile)
audiodub(video,audio)

ConvertToYV12()
------------------------------------------------------------------------------------------

Can I use a convertFPS or assumeFPS command in the script to prevent the sync issues, or should I be setting something different in xillisoft??

Except for the audio sync issues, the video plays smooth with great quality, fast forwards and reverses light lightning..

Appreciate any advice!

why not just use dpgenc that comes with moonshell 2.1?

hmm.. in my experience, dpgenc doesn't support the newer DPG3 & DPG4 file formats. The older types take forever to fast-forward or rewind when viewing on the DSI (the screen will freeze for 60 seconds if you hit fast forward). The version 3 & 4 formats are instantaneous.

It is strange that the DPGenc won't support the newer formats. Unless there's a newer of dpgenc that I'm not aware of?

don't really know, but it came with the latest moonshell 2.1 and seems to work ok, but i don't bother using it much as the ds is not a good vid machine. my kids have moved on to zunes.

hmm.. while I'm still curious to get the audio sync working with AVISynth & DPGconverter, maybe it's worth trying dpgenc again.

What are you using to demux the DVD streams, as I see dpgenc won't take VOB's directly?

Another vote for DPGenc (which came with Moonshell 2.1). Nothing makes better dpg files. I tried to use Xvid4PSP and although I could get one to play, it took forever to seek and the audio was horrendous! DpgEnc is the hands down winner. And I don't bother with making scripts either. I can just drop my avi/xvid files right on it and they encode. I could've sworn I've done mpegs and maybe even vobs too, but you have me doubting now.
