trouble with encore's handling of dgpulldown
Posted: Fri Apr 11, 2014 11:08 pm
First of all let me thank you for putting dgpulldown into the world. I'm working on a project to release some beautiful Soviet Era documentaries onto NTSC DVDs, and to be able to introduce them stateside at the speed they were meant to be shown (25fps) feels truly important.
So here's the impasse I'm at. Please bear with me as I'm very much new to this.
I am working from PAL Betacam sources that were digitized into 720x576 AVI files. After doing a little color grading on Premiere CS6, I transcoded the files to MPEG-2 PAL. I'm away from my work computer at the moment, but as for the specs I remember, I rescaled to 720x480, left the framerate at 25fps, put whatever the field order section was to 'progressive', and ran a one-pass CBR at 6.5. I think for PAL the GOP Structure is set at 15-3, but I've tried 12-3 as well. I also put the quality settings at their highest, did maximum rendering and maximum bit depth, and demuxed the video and audio into m2v and PCM respectfully.
Anyways, afterwards I ran my films through dgpulldown at 25 --> 29.97, and it worked great, only Encore could only output a bright red screen in my preview window when I imported them. I thought I found a solution in Restream, after deselecting the 'progressive' option for picture coding extension. Encore now could show the films in the preview window and allowed me to the author the DVDs without forced transcoding. I built a disc though and got varied results.
On a PS3, the films looked great. Crisp images and barely perceptible motion alteration, if any. That said on most players the video had serious stutter problems, and on one player played the films back at 30fps with chipmunk audio and all.
So here's the context to what seems to be the strange, hopefully fixable problem at the source of it all. When I went back to the Encore timeline I noticed that my films were condensed as if read progressively at 30fps (25/29.97x shorter), and then it put a black tail/slug at the end to account for what the runtime was supposed to be. Is that normal? Perhaps there's another setting I could check off at any one of the previously mentioned stages, or in Encore itself, that would read the videos and pulldown flags appropriately.
Thanks for your help in advance. I want to try any and all options to play these films at their original frame rate.
Best regards,
David
