Hi,
I've encoded a mpeg2 movie in order to make a svcd. It was a progressive 23,976 fps. After encoding, I've executed pulldown.exe (0.99d and 0.99c) movie.mpv movie_pull.mpv and the output movie was smaller than the original encoded one. I've tried DoPulldown and got the same smaller size and a "finished with errors" message. The original is about 1.46 GB and the pulldowned is 10KB smaller.
The same happened while encoding with the Sample filter to predict size. The original sampled movie had 1200 frames and the pulldowned 1185.
I think i'm losing frames here.
Any hint what's going on ?:confused:
Thanks in advance.

Edit - in the 1.46 GB pulldown, it ends at the right frame, 115260, but smaller.

Hi, I read at dvdrhelp forum
"... Actually, some better advice as stated in many other posts on this board would be to encode everything 23.976 and leave it. Most new DVD players will automatically play it back at 29.97fps if necessary. I found out the quality is not only better but 3:2 pulldown ruins the smoothness..."
Forum Thread (http://www.dvdrhelp.com/forum/viewtopic.php?p=755755&highlight=pulldown+exe#755755)

Is that true ? My dvd player plays 23,976 svcd, without pulldown, but sometimes friends borrow my svcds to play at their houses. In another forum thread I read that would be better pulldown concerning compatibility. Do the recent dvd players play well 23,976 not-pulldowned svcds ???

For compatibility, I would want to run pulldown. I just looked two 3.55 GB files (I make DVD's) that I have on my hard drive, one before, and one after pulldown, and they are the same size right down to the byte. I would think that the "finished with errors" message has something to do with it. Is your system stable? I would think it must be stable as you use CCE. Still, you should not get the "finished with errors" message. I have run pulldown (and DoPulldown) on many computers, and have never gotten an error message. Sorry I couldn't be of more help. Did you try a different movie BTW.

Yes. I've not made many svcds, but the last I made was ok, the same size before and after pulldown.
I guessed pulldonw.exe only put the flags, but at the thread link above one says it does more than setting flags. Is that true ? I'm beginning to think yes, that is true 'cause it processed all the 115260 frames and resulted in a smaller file. Any one knows what exactly it does ??

I've found what was causing error: I hadn't been checking "Add sequence end code" in video options. After checking it I encoded a short clip and pulldown ran smoothly!! :D
