Something went wrong with a NTSC PAL conversion.

[Talayero]

Hi,

I have a ntsc dvd I want to convert to pal.
It's 99.48% film and progressive, according to dgindex.

I used this script with CCE:

LoadPlugin("D:\DGDecode.dll")
Mpeg2Source("my film.d2v")
LanczosResize(720,576)
ConvertToYUY2

I configured cce to zigzag, progressive, frame rate 23.976 and without ticking the pulldown box.

Then I used the program DGPulldown to change the resulting mpv file. I used the option: Custom: 23.976 to 25.

The thing I think is weird is that the resulting mpv file and also the pulldowned m2v are both video 100%. I happened to load them in dgindex and it says that they are video. I don't understand it. Is that normal or did I make a mistake and something went wrong?

Thanks in advance.

When you created the d2v file, you were supposed to demux the audio track, i.e., ac3, dts, etc. (under Audio dropdown in DGIndex, I think?) So you should have had a d2v file an audio file. If you didn't do that, do that now (using the original source, i.e., NTSC DVD?).

Then you'll have the re-encoded m2v video file and the audio file. Re-author them together with menus, etc., then burn to DVD (which I'm assuming is your goal).

DGIndex doesn't have Video. Under Video Type, it has NTSC, Film (both possibly with percentages), or PAL. Does your Video Type really show as "Video"? Or maybe I should ask, "Where does it show as Video"?

Video Type - If the stream does not contain pulldown flags, this field will display "PAL" if the frame rate is 25.0 fps; otherwise, it will display "NTSC". If pulldown flags are present, this field will show a percentage "Film" or a percentage "Video" value. These two always add up to 100%, so only the greater of the two is shown.

Maybe I'm missing something. Please explain.

Looks like I missed something too.. misinterpreted the issue.

I explain:

I have an original film that has a resolution of 720 x 480 and 23.976 fps and I want to convert it to pal.

Then, after the conversion and out of curiosity, I did this:

I took the mpv file that CCE gave me using that script I wrote above (this mpv has a 720 x 576 resolution but still with the 23.976 fps from the original film), and I put it into the DGIndex.

DGIndex says VideoType NTSC, and at the end of the d2v file I can read "Video 100 %".

Then I take the m2v file I got after running DGPulldown. It's a file that has a resolution of 720 x 576 and a 25 fps.
DGIndex says Video Type: Video 83 % and at the end of the d2v file it says "82.92 % Video"

That is what surprises me, it should say PAL, I think, at least in this last file that has a 720 x 576 resolution and 25 fps. I don't know what it should say when the file is 720 x 576 and 23.976 fps, but anyway I'm afraid something is wrong or I missed some issue too.

Well, now I realize that manono may have answered my questions.

That quote says that is normal that dgindex displays ntsc if the frame rate is not 25. fps. That was the case of the file that had a 720 x 576 and 23.976 fps.

But I'm still wondering about the second case, the file that is my converted pal and has pulldown flags. The quote says: "this field will show a percentage "Film" or a percentage "Video" value." But 83% video is that normal?

Can't comment the exact value but it's normal that after 23.976 to 25 pulldown the video is no more 100% progressive: some fields (not complete frames) are combined to make extra frames shown. Some part of frames get interlaced (same as at usual film to NTSC telecining).

Yes, it's normal. The bottom of the D2V (you might have mentioned in your first post that you were referring to the D2V) shows only the percentage of film and video. It never shows PAL. You see PAL in the Information screen when running the Preview. Ordinarily, that bottom of the D2V will show as 100% Video if it's a pure PAL 25fps MPEG-2 video stream. It get's that information from the flagging, and normally a PAL MPEG-2 goes 2 2 2 2 2 2. It will only show as Film if there are the RFF flags present, and that will show in the D2V as 0 1 2 3 0 1 2 3. Again, 100% Film is only progressive 23.976fps with pulldown applied, a so-called soft telecine, making it play at 29.97. Because you applied pulldown to make the 23.976fps stream play as 25fps, with some RFF flags added to increase the output framerate, a small part of your stream is now film. You can look at it and see it's not all 2 2 2 2. For more about those numbers, please see Q31 of the DGIndex FAQ:
