Pulldown Question

[MNale]

My source video is 29.97 (from a film to tape conversion). It has the extra frame duplications from the telecine process (24 to 29.97 conversion). I want to encode this video to MPEG-2 for DVD playback on both progressive and NTSC monitors. I understand that by inserting the necessary flags for 2:3 pulldown, that most DVD players will play back the video properly on a PC and NTSC monitor. I have been unsucessful so far at making this happen. What do I need to do convert the video properly to MPEG-2 for this to happen? I would like to use CCE to do this.

Not sure exactly what you have to start...(is it MPG, AVI?) but if the source is now 29.97 and was built from 23.976 (FILM) you need to remove the repeated fields through Inverse Telecine (IVTC). I would recommend you use AVISynth with one of the several tools (e.g. GreedyHMA or Decomb). You then encode at 23.976, and use pulldown to mark for 2:3 pulldown.

My video I wish to encode to MPEG-2 is 8-Bit 4:2:2 Component Y'CbCr (720x486) Quicktime captured via Adobe Premiere 6.0 (Windows 2000 Pro) with a Targa 2000 DDR card from DigiBeta. How do I Avisynth a Quicktime file? I have tried this without success as well. Thanks for any help.

tools:
1. TMPGENcoder
2. QTReader plugin for TMPGEncoder
3. VFAPI Reader.
4. Avisynth
5. Pulldown

steps:

1. Load your .mov file in TMPGEnc (it would allow opening .mov file when you put the QTReader plugin inside the TMPGEncoder folder)

2. Set correct resolution/field order etc in TMPGEncoder

3. Save the TMPGEncoder project (as .tpr file)

4. Load .tpr file into VFAPI reader, then save as "fake" .avi

5. Load the .avi file into avisynth script, and put necessary IVTC command in there. Save as .avs file.

6. Load .avs (avisynth script) into CCE 2.50

7. Encode, but remember to check PROGRESSIVE, and remember, since it has been IVTC-ed in avisynth, it STAYS at 24fps when it is encoded to mpeg2 by CCE.

8. CCE-encoded mpeg2 file MUST be pulldown-ed (to add the repeat_first_flag and top_field_first flag). This will make your 24p Mpeg2 becomes 24p Mpeg2 + rff/tff. The resulting NEW file will be NTSC 24p progressive. It would play correctly on PC (progressive display), and it would play as NTSC interlaced by set top DVD player (by the player reading the pulldown flags in the mpeg2 file).

p.s. AND I STILL WANT TO TRY CCE v. 2.66 :)
