Single VOB from PAL to NTSC (Simple Steps?)

[bumpa]

OK,

I am aware that Donald Graft has written a nice lil utility that is supposed to take a PAL MPEG-2 based file and convert it over to NTSC. DGPulldown. I understand the steps here, but am trying to figure out which programs I should use to accomplish this. I am also working with a single VOB file. Music Video, no IFO files no Video TS directory.

STEPS as stated on the main page - (With Questions Inserted)


# Demux the video and audio streams.

Q- I am guessing use DGindex for this?

# If the video is interlaced, deinterlace it to make it progressive. If it is already progressive, skip this step.

What is a simple way of determining if the Source is Interlaced? What program would I load the .M2V file into to De-Interlace?

# Resize the video to 720x480.

Q: Reccomended Program, steps??

# Encode the video to MPEG2 at 25fps progressive.

Q: I tried this with the latest version of TMPGenc and forced the 25fps, it still did not come out right, was 23fps or something.

# Run DGPulldown on the video MPEG2 stream to flag it up to 29.97fps (using the 25fps --> 29.97fps conversion).

Q: Ran this and ended up with a file the same size and same attributes as the original.

# Mux the audio and video into a program stream, or author a DVD using the audio and video streams.

Q: Never got this far, see above.


----------------------------------------------------

Does someone have a formula of programs and steps to get from point A to Z with this? Is it a bugged process? I saw a guide on vcdhelp.com but it does not do the trick.


Thanks

What is a simple way of determining if the Source is Interlaced? What program would I load the .M2V file into to De-Interlace?Use DGIndex. In the menu select "Preview" and the video should start playing. Then in the box to the side, it should say if its Film or Interlaced (or both). You could also framestep through the video to see if you notice interlace combing artifacts.

Use AviSynth to deinterlace. TDeint, Decomb, etc.
Do a search for "AviSynth" and "deinterlace" and you will find hundreds of threads to tell you what to do.


# Resize the video to 720x480.
Q: Reccomended Program, steps??In DGIndex save the project to create a .d2v file.
Use notepad to create the AviSynth .avs file.

mpeg2source("C:\video.d2v)
LanczosResize(720,480)
Open the .avs file you created in notepad with TMPGEnc and encode.


# Encode the video to MPEG2 at 25fps progressive.
Q: I tried this with the latest version of TMPGenc and forced the 25fps, it still did not come out right, was 23fps or something.Most likely your settings are wrong. Verify that your output is set to 25fps and 720x480 for the resolution. If you have it set correctly for 25fps it will not output 23.976.


# Run DGPulldown on the video MPEG2 stream to flag it up to 29.97fps (using the 25fps --> 29.97fps conversion).

Q: Ran this and ended up with a file the same size and same attributes as the original.Thats right. All it is doing is adjusting flags. It is not actually adding frames. The flags tell the player to repeat frames.


# Mux the audio and video into a program stream, or author a DVD using the audio and video streams.

Q: Never got this far, see above.TMPGEnc can Mux.
If you want to author, MuxMan is a good choice.

Thanks for the play by play. I have not played with AviSynth much however your walkthru makes it seem easy.

I will try this when I get home tonight and let cha know.

Thanks Again
