mixing PAL and NTSC clips in iDVD or DVD Pro

[Alexander Kallas]

[Rafael Amador] “You can do it al in one rendering-export.
I would do it this way:
– Edit in a NTSC DV sequence.
– Color correction. Then drop the Chroma Smoothing (but set it before the CC filter. Must be the first one).
– Set the graphics and whatever you need to add.
– When your sequence is finished, set it to 8 or 10b Unc (if you set the sequence to render in High precision).
Then you have three options to send to Compressor. The easiest (and the best) is to send from the FC time-line.
Then choose one of the presets for standard conversion.
As I told you yesterday, set the Frame control to ON. And in the Output fields, set it to “Upper-first”. 8 and 10b Unc, are expected to be “lower-first” in NTSC, but “Upper-first” when PAL.
Anyway Chang, build your NTSC DV sequence, and when ready we can workout the problems that could arise.

Hi Raf,
Strange but good, how one thread links to another.
I must challenge the above theory on 8 or 10-bit uncompressed from a DV time-line.
The field order won’t change in DV>8 or10-bit uncompressed.
You have been sucessful inspite of this error, because in Compressor as you said in another post, if you transcode to m2v with field order the “same as source”, all will be well, so your error doesn’t surface.
Does this make sense?
Just read this post, https://forums.creativecow.net/readpost/8/997809
and comment back to me.

Cheers

Hi Alexander
[Alexander Kallas] “The field order won’t change in DV>8 or10-bit uncompressed. “
That is in NTSC, but in PAL DV is Lower and 8/10b is Upper.
However the field order is not important as long as the applications and the video editor have the things clear.
I’ve been making DV clips Upper and sent them to Compressor.
No problem as long as Compressor knows which field have to read first.
When you send from FC, Compressor knows the field order.
Only in some cases (for example when you go to print to video) is necessary to keep the field order of the standard. DV when go to tape have to be always Lower. 8/10b Unc have to be Lower or Upper depending if they are NTSC or PAL.
