Need advice here (re: re-converting MPEG-2 FILM/NTSC files)

[dark_myuutwo]

Hey,

I have a question.

Here's what's going on: I'm working on a DVD project with the 7th Pokemon movie, where I'm using the widescreen video from the Japanese DVD, and the audio tracks from both the English and Japanese releases (the latter, which I will be making new DTS soundtracks from - but that's not the issue here).

My problem is, is that when I try to re-convert certain portions of the movie, which is encoded as FILM - 23.976fps (internally 29.97fps), using the following settings under TMPGEnc, the video is slightly jerky (using 3:2 pulling when playback and 23.976fps (internally 29.97fps) only made it even more jerky). I realize it could be a playback issue, but the original file plays fine, so I'm wondering...

Anyways, the settings used are:



My advanced settings are also:

Video Source Type: Non-interlaced (progressive)
Field order: Top Field First
Source Aspect Ratio: 1:1 (VGA)

Video arrange Method: Full Screen
Deinterlace (Odd field (animation adaptation))
*Note: I also used Even field, which appears to be 5% more jerkier when played back...


My question is, what are the best (or most recommended) settings I should use in this situation, so that the video is the same as the original?

I've done searches, and I can't find anything that would help me in this situation.

I need to know asap, as I would like to get this done tomorrow!

Any help would be greatly appreciated, thanks!

Hi-

Why are you deinterlacing at all since you said it's film? I can't comment further, since I don't use TMPGEnc to encode, but some of the other settings seem peculiar to me also (CBR encoding?). I'm sure a TMPGEnc expert will step in to help.

Set Encode mode to "3:2 pulldown when playback" and frame rate to "23.976 fps (29.97 fps internally)".

Also - some anime has a mixture of 23.976 and 29.97 fps sections.

And like manono said, don't deinterlace.

[dark_myuutwo]

OK. So, then for the Advanced tab --> Video source type, do I leave it as Non-interlace (Progressive)?

Yes, assuming that's what it is.

[dark_myuutwo]

OK, I still have an interlacing problem with the picture, as shown below



It shows interlace lines, which are NOT present in the original source. And even then, this video's still jerky.

I don't want these lines to be there, but I don't want it to be jerky either.

What should I do?

EDIT: This screencap was taken from PowerDVD, if that helps any

dark_myuutwo, How do you know your source isn't interlaced? Many software DVD players will deinterlace on-the-fly because interlaced video looks terrible on a PC. So you can't judge by that. I'm not sure that TMPGEnc is always right about the source interlace format either.

The picture you posted (960x540) is not a normal DVD frame size. It definitely shows interlace artifacts but it also shows improper resizing of an interlaced image.

You must have ripped the original VOB files off a DVD -- open one in VirtualDubMPEG2 and step through the frames. Do you see any interlace artifacts? (VirtualDub shows you the exact content of each frame, no deinterlacing, etc.) Select File -> File Information. What does it say about the file? 720x480, 23.976 fps? 29.97 fps?

It will hard for anyone to help you unless they know exactly what you're starting with, and were you're going with it (DVD?).

No, I don't see any interlace artifacts.

It says for file information:

Frame size, fps - 720x480, 23.976fps
Aspect ration information - DAR = 3 (16:9) "Flat"


As to where I'm going with this - it's all going to a DVD+R9 (or DVD+R DL) disc.

EDIT: Also, I did not resize the video to 960x540. That image is just how PowerDVD plays and captures screenshots, due to my screen resolution. It's not how the video itself was re-encoded.

Regardless, it shows the same thing in Media Player Classic, which is normally bad for not deinterlacing DVD video streams much or at all, IMO.

[dark_myuutwo]

Odd.

Even though the original DVD video is progressive, TMPGEnc thinks it's interlaced, as evident in this screencap:



Why is that?

[junkmalle]

Are you sure you're checking the same file with VirtualDub and TMPGEnc? VirtaulDub says it's 720x480, 23.976 fps (which should be progressive), TMPGENc says 853x480, 29.97 fps. I'm guessing the file in TMPGEnc is one you've already converted. Note it's not a valid size for DVD either (DVD must be 720x480, 352x480, or 352x240 on NTSC systems).

Do you actually need to convert the files? Is it just that you can't fit all the VOB files on one DVD+R9?

[hrlslcbr]

Use DGIndex to get the 23.976 original frames, and then encode in TMPGEnc with the settings suggested above. This way, TMPGEnc should 'see' the file as being 23.976fps and progressive.

No, the file you're seeing is the original ripped file from the Japanese DVD. I'm trying to RE-convert the file

It's more complicated than that. I'm mixing the English credits from the dub with the Japanese video, so that's why I need to re-convert. It's something I want to do.
Also, even if I wasn't, I'd have to re-convert the video down to a size of 4GB, because my 40GB hard drive is a FAT32 drive, and I have no additional drives (especially NTSF ones) that I could send the video to in one chunk.

How do I go about doing that?

[manono]

Video->Field Operation->Forced FILM. Then File->Save Project.

I'd say that if you don't yet know how to use DGIndex, you may have bitten off more than you can chew. But with a little handholding, you may get throught it.

Does TMPGEnc open Project files? I don't think so, so the next step would be to put it into an AviSynth script file. I'll let those more knowledgeable with TMPGEnc take over again.

[dark_myuutwo]

Actually, I found a quicker way, using that program listed above and another which I think I found thru one of the guides for DGIndex.

Now my videos look perfect. Thanks for the help guys!

[hrlslcbr]

Good to hear that.
BTW, the videos might be perfect for watching on your PC, but if you didn't add the 3:2 pulldown, they won't look 'perfect' on your TV.

I'm still lost, could you please tell me how you fixed your problem, cause i am having the same problem you had
