Hi, Many thanks for the reply, there are some really interesting links in your blog (those which are Korean I don't understand unfortunately). The problem I got is finally very simple. I just want to transfer a TC to FCPX time as simple and fast as possible. For described reasons I can't use CMTime. An option could be to using "2400000" for any video related thing (this for example would not cover 96 kHz audio). The above "2400000" base does work perfect if you got a few clips. But if you got more than a few FCPX will take forever to resolve the timing. Regards Andreas Kiel On Aug 20, 2012, at 10:22 PM, JongAm Park wrote: > Hello..

I have my own blog post about it, so it would be helpful to read it.

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".

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... -Kevin On Tue, Aug 7, 2012 at 4:21 AM, Andreas Kiel <kiel(a)spherico.com> wrote: > 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 > > > _______________________________________________ > Do not post admin requests to the list.

FCPX TC Question
by Andreas Kiel 07 Aug '12

07 Aug '12

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.
