Try to ignore the above spammer.
Motion is a good way to customize the TC generator beyond the limited parameters we're give in FCP.
Nope; didn't type in the values.
There are are at least three ways to get source TC. One uses Compound Clips, opening them in the Time Line. The second exports directly from the Event Browser, The other uses Compressor's TC filter.
Here's a link that describes the first method. (Afraid I couldn't locate the one I originally learned this from.)
And here's one that describes the second approach.
And here is the Compressor way.
Drop a clip on a Project and then open the Title Bar and Drag and Drop the Date/Time Tittle over the clip.
Beware of some problems displaying the correct time due to your Mac's timezone options. I'm currently in -5 GMT and with the 9.0.6 version the Date/Time Tittle will substract 5 hours from the original time. Older versions didn't have that problem.
Also beware of a mobile phone issues. Iphone / Android will write the date and time of its video files when the file ends so you need to substract the lenght of the clip from the time shown on the file.
Hope this helps
