Converteing NTSC 29.97fps to PAL

[CarlosJorge]

Hi.

First of all, let me tell you I'm still using TFM 1.2, but since I don't see anything in the change logs concerning this priblem, I'm assuming it still exists in v1.3.

Converting NTSC 23.976fps to PAL has worked every time without a single problem. However, using a 29,97fps source didn't work as well.

After converting I ended up with a 5.1GB DVD folder and a movie 18 min longer then it was. My movie was 91 min long and now the DVD is 109 min.

Take a look at the AVS script
--------------------------------------
# 16:9 encoding
Import("C:\Program Files\The FilmMachine\AviSynth\ResampleAudio.avs")
LoadPlugin("C:\Program Files\The FilmMachine\MPEG2DEC\MPEG2DEC3.dll")
AVISource("G:\Downloads\Movies\Movie.avi",False)
ConvertToYUY2()
AssumeFPS(25,1,True)
LanczosResize(720,576,0.0,0.6)
ResampleAudio(44100)
---------------------------------------

The line "AssumeFPS(25,1,True)" is OK for 23.976 or 24fps, but for 29.97, isn't it necessary to perform an IVTC first?

Without doing this, it really results in a longer movie, and since the bitrate was calculated for the original time, the DVD becomes oversized.

Anyone else has had this problem?

Cheers

It is better not to do a 29.97 to Pal conversion because most of the time the audio is very bad due to this conversion. The gap between 29.97 and 25 fps is to big. It is best to use 23.976 to Pal.

If anyone knows how to make a working 29.97 to Pal conversion please tell and I will give it a try and implement it.

VII. NTSC (Video) DVD (29.97i Fps) -> PAL DVD (25i Fps)

1. Run DVD2AVI and load the decrypted VOBs using the "Open" item in the "File" menu (you need to choose only the first one of a sequence).
2. Check the "None" item in the "Field Operation" sub-menu of the "Video" menu.
3. Choose the desired audio track number (usually "Track 1") in the "Track Number" sub-menu of the "Audio" menu.
4. Check the "Demux" item in the "Dolby Digital" sub-menu of the "Audio" menu.
5. Check the "Auto Select" item in the "Channel Format" sub-menu of the "Audio" menu.
6. Check the "Off" item in the "48 -> 44.1 KHz" sub-menu of the "Audio" menu.
7. Select the "Save Project" item in the "File" menu.
8. Choose a location and filename for the DVD2AVI project name. A small text file with the D2V extension will be created, and the audio track specified above will be extracted from the VOB into an AC3 file in the same location.
9. Create and open a new text file with an AVS extension (to be used with AVISynth), using your favorite text editor (like Notepad).
10. Add the following lines, filling in the location and filename of the file you created above:

LoadPlugin("MPEG2DEC.dll")
LoadPlugin("SmoothDeinterlacer.dll")
MPEG2Source("DRIVE:\PATH\VTS_xx_x.d2v")
SeparateFields()
Weave()
SmoothDeinterlace(doublerate=true)
ConvertFPS(50) # or ChangeFPS(50)
LanczosResize(720,576)
SeparateFields()
SelectEvery(4,1,2)
Weave()
ConvertToRGB()

11. Save the AVS file.
12. Ensure that MPEG2DEC.dll is installed. (If this file is placed in the \WINNT\System32 or \Windows\System directory, the full path is not needed, as illustrated in the above script. Otherwise, add the full path to the LoadPlugin() command.)
13. Ensure that SmoothDeinterlacer.dll is installed. (If this file is placed in the \WINNT\System32 or \Windows\System directory, the full path is not needed, as illustrated in the above script. Otherwise, add the full path to the LoadPlugin() command.)
14. Load the AVS file into TMPGEnc as the "Video Source."

NOTE: Cancel the Wizard dialog box which appears when you run TMPGEnc.

15. Load the "DVD (PAL)" template into TMPGEnc.
16. Load the "unlock" template (located in the "Extra" directory).
17. Select "Video only" in the "Stream type" region.
18. Specify the location and name of the "Output file name" with an M2V extension.
19. In the "Rate control mode:" field, choose the type of encoding you want. Multi-pass variable bit rate (VBR) settings produce better quality, but take longer to encode. Choose your bit rate based on quality desired, length of video, size of AC3 above, size of other files that will be on the destinaion disc, and the size of destination medium. Do not exceed 9800 kbit/sec.
20. Choose "Motion estimate search (fast)" or "Highest quality (very slow)" in the "Motion search precision:" field on the "Video" tab of the "Setting" dialog.
21. Press "Start" to convert, and encode the video.

This is for mpeg files, does it also work with AVI files?

And then there is still no solution for the audio.

Hi

I think this can be done.

The audio isn't a problem since the duration of the movie does not change with 'ConvertFPS(50) # or ChangeFPS(50)'.

The problem I see is that this method will be good for TV material (non telecined), but for movies (telecined) an IVTC should be in order.

I guess there'n no easy way to do it. The source would have to be analyzed first (is it FILM or mostly?) etc.

dont know or its the same situation, but i just converted xvid-avi (ntsc) to dvd (pal) and unless all tuto's advice tot extract audio separate and convert video separate i just clicked like im stupid (choose pal .mcf) and the result is just perfect (NO subtitling programm) only used tmp and no others proggies ....
