Removing almost every 3rd frame?

[manono]

Possibly, although on the dozen or so standalones on which I've tested DGPulldown'd videos, I haven't seen it. I have seen something similar when using V 4.0 of PowerDVD on the computer. The audio is fine, but the video has this speedup/slowdown variable motion thing going on. When I test in other software players it's fine. I'd suggest taking it around to some friends with different players to see if it happens when using their DVD players. If not, then you'll know your player is defective, as it doesn't handle all kinds of pulldown patterns correctly, as it should. What DGPulldown produces is perfectly "legal" and compliant.

Make sure the DVD you made is really NTSC. I've seen cases of people goofing up the process and actually authoring a PAL DVD when they thought they were making an NTSC one.

As manono says, try the DVD on some other players. Cases of the pulldown not being handled properly are extremely rare. If it plays wrong on them all, then you goofed up the process.

Regarding the frame rate going into TMPGEnc when you have an oddball like 19.98... You just lie and put an AssumeFPS() to some legal rate (25fps makes sense), for input to TMPGEnc. Then in DGPulldown do the custom rate as if you did not lie. DGPulldown will make everything correct.

Your last paragraph is interesting, neuron2. I don't use TMPGEnc, so I don't know its settings. You have to do something similar with CCE, as you can only tick fps boxes for legal framerates. I feed it a 19.98fps .avs, tick 23.976, and it comes out OK when using DGPulldown for 19.98->29.97fps, as you said.

But I also have to adjust the bitrate, or I come out undersized in the end, as CCE thinks it's dealing with a 23.976fps video. You multiply the min, ave, and max bitrates you want by 1.2 (23.976/19.98=1.2) in order to make it come out with the correct bitrate and filesize at the end.

Do you reckon if I add AssumeFPS(23.976) to the .avs as you sort of suggested, I wouldn't have to adjust the bitrate? I'll have to try the next time I have one like that.

I don't know much about CCE. Is that box you tick for the output frame rate? If so, I'd be worried that CCE would duplicate frames or something to convert the 19.98 to the ticked rate. I don't know what the answer is to your bitrate question. Strangely enough, I never encode things where I care much about the final file size, it is either short swimming clips or long transport streams that are padded up to a defined CBR anyway. I never encode movies (except to test DGMPGDec now and again)! I'll be curious to hear of your results though.

My guess is that it will work the same way. But with TMPGEnc, it will try to convert the frame rate in your scenario, IIRC, so that's why I do the AssumeFPS().

[manono]

I guess it's both the input and output framerate. It doesn't duplicate any frames, but just speeds up the action. The MPV fresh out of CCE plays fast, but is OK again after going through DGPulldown.

That's exactly what I did. I used AssumeFPS(23.976), then chose that rate in TMPGEnc.

I tried it in a friend's player, it played fine. So I guess my player is the 1 in a 1000 that can't handle it. Although, mine can play DVD-RW's, and his can't at all. Wah ha ha. I have a Samsung M301. Got it maybe 5 years ago. I've been thinking about replacing it with one that has a surround sound system built in, but there's just no good place to run the wires, and i'm not a millionaire, so I can't get the infrared ones.

[manono]

Funny, I have that wire problem myself. The living room rug is sort of nailed down, and can't be pulled up to run the rear speaker wires under it without a great deal of trouble. So, the surrounds have long wires, and I move them when playing DVDs, having the wires on top of the rug, all ugly and everything, and put the speakers back by the TV and DVD player when done. It's not pretty but it works.

Too bad about the player, though. I make lots of 19.98fps with DGPulldown silent film DVDs, so it would hurt me if my player didn't play them correctly. If you have only 1 like that, not so bad, though.
