MPEG 2 3:2 pulldown repair

[trooper11]

I am having a problem with a batch of videos i converted to mpeg2 for buring to dvd.

somehow, some of them came out with a 2:3 pulldown, while others came out normally. I dont exactly know how this happened, since they were all set up in the same batch encoding session in tmpg, but it did.

what i am wondering is if there is anyway to only fix that, i guess going from inverse 3:2, which is what i assume happened, to normal 3:2. i dont want to have to go through reencoding these al over again which would take a day. are there any such programs that allow this to be done? Thanks.

Anyone have any ideas on a solution? Id appreciate any help

Pulldown is applied if you are using the wizard and your source is 23.976.That's normal,any reason its a problem for you?More details.

I'd take a stab but I'm not sure I understand what you're saying.

If you started with 23.976 fps progressive video you want to convert to 23.976 progressive mpeg2 flagged for 3:2 pulldown.

If you performed the pulldown in software and created an mpeg2 file with the pulldown already encoded you can just use it like that, or redo the conversion.

What did you batch encode.. AVI's ??

Chances are then, that your source did not line up with the 3:2
pattern during AVI batching. Whereever your split your AVI's
and stitched them together, did did not do it in 3:2 groups. And,
when your IVTC got to it, it missfired on some scenes. I don't
know how bad it is, because you didn't say exactly what your
process was, and how many AVI pieces there were for batching.

When you cut your AVI's apart, you need to do it in 3:2 groups
(if your source if Film)

If you are going to cut, always cut at the END of the 3:2 pattern.
For insance, if your pattern is like this..

-/- represent the cutter

WRONG cuts:
PPPII PPP-/-II PPPII PPPII PPPII P-/-PPII PPPII

CORRECT cuts:
PPPII PPPII -/- PPPII PPPII PPPII PPPII -/- PPPII

But, in order for even the above to work correctly, your source
type has to be Film (Telecine) and, if it is Film, it has to
have no glitches. There are lots of these bad Film sources
that get captured, and run through an IVTC process, and still
poor results are common (but people can't put two and two with
this) The source type *MUST* be perfect in order to IVTC 100%
accurate. And, couple that with the above, and you can never
miss.

Well my sources are avi files encoded in xvid.

i was running a batch of 8 xvid files (anime episodes) and everythign was set as it always was, with 3:2 pulldown selected. These xvid videos did have a 23.976 framerate. I am follwoing a guide for converting xvids to dvd and as per the instructions I set it to convert that to 29.97 NTSC. Also, I am using the video only, I seperate audio and video before putting it into tmpg.

Ive done this before with a batch of 9 files and had no problems with any of them. i didnt do any cutting in tmpg, the only thing i did edit was resizing, as i did in the previous batch. I dont cut the videos until after they are properly encoded.


but after these 8 were done and I was putting them into dvdlab pro to set up menus, under system it lists 4 of the videos as 2:3. I thought maybe it was just misreading it, but when i finished the menus and burned a dvd of it, the 4 episodes listed as 2:3 are not viewable on the television, only the audio plays.


what i want to do is repair those 4 episodes that are in 2:3. is there anyway to do that without just re-encoding them completely?

I don't know what you mean by "4 episodes that are in 2:3". You should be more precise:

You can either encode as 23.976 fps progressive MPEG and have the DVD player perform the 3:2 pulldown when it plays it, or you can perform the 3:2 pulldown in software to make a 29.97 fps MPEG file that the DVD player will play "as is".

I suspect the four files that don't play were encoded at 23.976 fps progressive but weren't flagged for 3:2 pulldown. There are two programs in the Tools section that can fix this DGPulldown and Pulldown.exe.

by 4 episodes i mean 4 of the video files encoded in the batch session. i dont understand it either, but in the file properties listed in dvdlab pro it says taht the 4 encoded files in question are in "2:3 pulldown"

now in tmpg,there is just one setting for the pulldown method and it applies to all of them, so i dont know why some wouldnt follow that, but ill give those two programs a try, thanks.
