</timecode> ...

This will be imported as 29.97 frame rate with NDF. If I export as XML I do see the same. I also can switch in the sequence settings from DF to NDF.

Using a sequence preset for 30/60 NDF I can't switch between DF/NDF but the tc in the XML is always DF?????

Using any 29.97/59.94 DF sequence preset I can switch as with the above example to NDF in FCP and the XML stores the NDF TC flag, string and frame.

So from what I tested I got now:

if NTSC is "TRUE" then I'm able to see both DF/NDF timecode and frame and the correct DF/NDF entry

if NTSC is "FALSE" and TC is NDF I always will get DF timecode and frame - hmmm???

Thanks

Hi all,

I got a bit confused (again) about NTSC and (again) about XML.

a) If I create a timeline using some codec, some size and set the editing timebase to 60, I get a NDF timecode in FCP (start TC 01:00:00:00)
b) If I create a timeline using some codec, some size and set the editing timebase to 59.94, I get a DF timecode in FCP (start TC 01:00:00;00)
So far it's easy.

If I create XMLs out of those I got following:
a) editing timebase=60, NTSC=FALSE, timecode=DF (<string>01:00:00;00</string>)
b) editing timebase=60, NTSC=TRUE, timecode=DF (<string>01:00:00;00</string>)

If I re-import those XMLs into FCP
a) editing timebase=60, NTSC=FALSE, timecode=NDF (01:00:00:00)
b) editing timebase=60, NTSC=TRUE, timecode=DF (01:00:00;00)

So I am a bit confused about these things. How is it handled?
30/60 always seem to be drop frame internally always, so when reading out an XML and encode the timecode you will get DF timecode always.

Depending on what you do with the data this might give you
a) wrong frame numbers when the timecode is converted to frames (when based on the TC string)
b) wrong TC (when based on frame numbers)

Questions are:
a) can the NTSC flag be ignored and if yes why it is there?
b) why is the "rate" there twice ('main item', timecode entry) and how do they relate? (Or what's the idea behind)

Maybe somebody can help me out here.

Thanks
Andreas
