Thanks for the comments. As Jon suggested I will do own little script since I've to keep some legacy apps running on 10.5 and 10.6 where CMTime won't work. There are some other questions: What is NTSC 29.97 NDF for video - I've seen that for audio but never for video What is PAL 25 DF - there is no DF with PAL. -Andreas On Aug 11, 2012, at 2:59 AM, Kevin Dixon wrote:

If you take the ratio the time codes you give... 1:01;06 = 61.194466666666666666666666666667 1:01;04 = 61.127733333333333333333333333333 which makes perfect sense-- the notion of specifying time code as the ratio of two numbers is present throughout Apple's multimedia APIs. For example CMTime struct, stores "value" and "timescale". I assume that 30000 might correlate to 30 fps...

Hi all,

Does anyone know about any docs on how to handle TC to FCPX time conversion for XML.

While it looks simple at the first glimpse it seems to be more complicated at the second look - with DF TC

An example: A sequence which starts with "00:01:01;06" will show up in the XML with "tcStart="1835834/30000s"" A sequence which starts with "00:01:01;04" will show up in the XML with "tcStart="146706560/2400000s""

Any hint is appreciated.

Andreas
