Hi fellow board members,
the following text got a little longer than expected, so sorry in advance...
I'm running into a little trouble here right now and would appreciate any help from other experienced board members. I have been using Adobe Encore for some time now, so I'm actually used to it, but I have used it to get interlaced material on DVD only so far (until now).
What I want to do is getting my old DAVID LYNCH'S INDUSTRIAL SYMPHONY NO. 1 Laserdisc onto a DVD as it slowly begins to exhibit dropout due to laserrot.
What I've done so far: my LD Player is hooked up (via S-Video) to a Panasonic HDD/DVD-Ram recorder. I used the Panasonic to record the LD (only 50 minutes long) at the peak datarate onto DVD-Ram and copied the resulting DVD-Ram contents to my PC afterwards (something very similar to a .vob file).
The Panasonic records at 29.97 fps NTSC the exact content of the Laserdisc. Since the LD material is (except for the ending credits) film-sourced I definitly wanted to do IVTC.
I used TMPGEnc (3.0) to clean the picture up (noise reduction, sharpness boost and of course De-Interlace by using Inverse pulldown)
and had TMPEGEnc output a 9.5 mbit/sec MPG2 file setting the output to 23.976 frames.
The IVTC worked real wonders, 2 of 5 frames were "mismatched" before and after the IVTC I had 99.9% rock-solid progressive frames.
After this I fired up Adobe Encore to make a DVD from, but had to learn right away that Encore won't even let me import the MPEG2 file without transcoding it right away - so I cancelled the Encore usage for the moment.
I checked the internet and found that NTSC DVDs run at 29.97 fps all the time. With the great IVTC job I don't want to go back to "interlaced" by any cause, so I learned about encoding with 23.976 fps with an added flag "3:2 pulldown playback" which sounded very good (and actually all good NTSC movie DVDs are done this way).
I encoded the material once again, with the Video settings in TMPEGEnc set to "23.976 fps (internally 29.7 fps)" and added the "3:2 pulldown playback" flag.
I used TMPEG DVD Author to do a quick authoring with the material and it worked great (besides the fact that TMPEG DVD Author complained about a wrong GOP sizing although it was set to 18 frames)).
Now the problem: Adobe Encore still won't accept the newly encoded video file and forces me to transcode the video to "real" 29.97 frames.
A very nice feature of my Sony DVD Player is that I can check the encoding by step-framing one second of playback and counting the steps till the counter advances one second. On the DVD done with TMPEG DVD Author I could count exactly 24 frames from one second the the next. That's exactly as it's supposed to be with a real 23.976 fps progressive source (and it's way on most Hollywood DVDs I tried as well).
When I allow Encore the transcode my video to 29.97 fps (and I might add the Encore screws up the audio entirely by doing this and Encore's internal MPEG2 encoder is nowhere up to TMPEGEnc) I can count 30 fps by step-framing one second on my DVD player - which is total crap in my eyes as it annihilates my IVTC efforts before.
The question is now: how can I produce a DVD using Adobe Encore when my video material is 100% film based / progressive ?? I know that I could leave the material telecined or add a 3:2 pulldown to my IVTCed material again and going 29.97 fps this way, but isn't that crap ?
While I can accept that Encore isn't the Scenarist class (and I might add that Encore was expensive enough and there's no way I will ever afford Scenarist), I really cannot believe that Adobe would release a DVD authoring tool totally unable to handle 24 fps progressive material in any way besides re-encoding it ?
Any help on this topic is highly appreciated !
Thanks
Tobias
