[Tig] best way convert 24p to PAL

[Steve Roberts - Post Production]

If you *must* keep the duration the same, there are only two ways I can
think of:

1) - repeat one field every 12 frames (which is what you have already
seen), giving a stutter every half a second.

2) - use some kind of motion-estimated re-timing device to analyse the
motion of objects through the 24fps timeline and re-map them onto a
25fps timeline. I have no idea if such a thing exists.

Alternatively, just do what everyone else does for optimum quality...
Forget about keeping the duration the same and just speed eveything up
by 4% so that you're outputting 25fps!

Without considering the resolution aspect, what is the best way to
convert 24p to PAL, and the duration keeps the same. It seems that in
the Smoke and Lustre, every other frame is duplicated, I do not
understand why they do it like that. And for Sony F500, it duplicates
one frame every 12 frames, that is the best quality I can get, I mean
without the interlace effect and the motion objects do not seem to jump
every secend. it is really confusing to me.
