problem with a NTSC interlaced movie, help needed

[pjolin]

I'm trying to make a backup of a NTSC interlaced movie and... PROBLEM append!

What I did:
A)CCE setting
1-Video Setting: MPEG 2 (ES, Multipass VBR), Multipass VBR setting 3 pass and "Creat New File"
2-Advanced Video: "Add Sequence end Code", "DVD Video Compliant", Luminance Level "16 to 235", Frame Rate "23.976", Quantization matrice "Mpeg Standard"
3-Advanced Quality: DC Precision "10" (as gave by bitrate viewer), Bloc Scanning Order "Alternate" (as gave by bitrate viewer)

B)Pulldown Setting

1st test: pulldown in.m2v out.m2v
2sd test: pulldown in.m2v out.m2v -prog_frames i
3rd test: pulldown in.m2v out.m2v -prog_frames i -prog_seq i
4th test: pulldown in.m2v out.m2v -prog_frames i -prog_seq i -norff

Results:
test 1:
imported in DVDMaestro without problem, but in the preview appear some stranges images (some progressif images was insert in the movie)!

test 2:
impossible to insert in DVDMaestro: progressif flags...error!

test 3:
Same as test 2

test 4:
imported in DVDMaestro without problem, but the lenght of the movie is now shorter then the original (movie is to fast now)

Any body may help me
Thanks

You don't run PULLDOWN on an interlaced encode, since you are encoding at 29.97fps already. Also, never use PROG_SEQ I on an interlaced video (and almost never on a progressive video).

You also told CCE to set the framerate to 23.976, but your video was at 29.97 to start with. In other words, you started out bad and did nothing but make it worse. Re-encode with the framerate at 29.97, don't run PULLDOWN, and feed it into Maestro. That will work.

If you haven't damaged your original encode, this command should make everything correct:

pulldown -nopulldown -framerate 29.97 in.m2v out.m2v

As you said the original movie (the one ripped) is at 29.97fps, but after you saved your movie with DVD2AVI, your movie become a movie at 23.976fsp!

(or how we do for keep the movie at 29.97fps)
Cause each time I saved my file with DVD2AVI, even if the original file is a 29.97fsp movie, that will be save at 23.976fps... Also if I take that file and put the CCE fps option at 29.97, the resulting motion will be faster then the original (like the actors will run when they should walk !!!)


Then at the re-encoding step with CCE, you must keep the same fps as the source file (the one creat with DVD2AVI, that's mean 23.976 in my case) because the pulldown option in CCE not work correctly.

That's why I must use pulldown to bring my movie back at 29.97fps and be able to import it in DVDMaestro..

Thanks for you help

Uncheck the FORCE FILM option in DVD2AVI. DVD2AVI defaults to the LAST SET OF OPTIONS that you checked.

[pjolin]

sorry but i don't understand

In DVD2AVI we have:
VIDEO :

IDCT Algorithme : 32 Bit SSE2 MMX

Field Operation : FORCE FILM (the option ti change...)

Color Space : YUV 4:2:2

YUV- RGB : TV SCALE

You said: uncheck the force field... but i have to check something witch one?? "None" or "Swap field order"

I think "NONE" should be use with PAL movies???

Thanks for the help

[slk001]

Use NONE for FIELD OPERATION. That will retain your native fps (which is what you need).

[pjolin]

If it possible to use "none" for the "field operation" in a NTSC movie, how come we don't use this setup for all NTSC movie even if it is a progressif movie and always keep the original fps?? It could be easiest by this way! No?

Thanks

Easy? Yes.
Smart? No. Requires 25% more space to encode this way (or 25% more bitrate).
