DGPulldown PAL <-> NTSC

[Prodater64]

Can DGPulldown do conversions in both ways?

1 - I now we can do 25 to 29.97 fps flagged, resizing to ntsc resolution.
2 - Can we do 29.97 interlaced to 25 fps flagged, resizing to pal resolution, if we deinterlace it first? Please post a good avisynth script to deinterlace and say me if it is the same for commercial movies, ntsc and pal captured material.
3 - Can we do 29.97 progressive (doesn't matter that you hardly can have such material, I need an answer anyway) to 25 fps flagged, resizing to pal resolution.
4 - Can we do 23.976 to 25 fps flagged, resizing to pal resolution?
5 - Could also explain another DGPulldown functions.

1. Not a question.

2. If the source is flagged from 23.976 to 29.97, you can strip the flags and reflag it to 25. If the source is not flagged, then you are out of luck. The principle to remember is that flagging can only add extra fields; it cannot remove them. But if flagging is already present in the source, you can strip that flagging and thereby remove the extra fields.

3. No, if by progressive, you mean unflagged 29.97. Otherwise, see above.

4. Yes, but judder on pans might be perceptible.

5. Please see the main development thread and then ask specific questions if anything is still unclear.
