Jim, I'm having a hard time to understand your issue here.
The Pocket and the Ursa do exactly the same: They either show you the free run timecode (int or ext) or clip duration. Only difference is that Ursa can show both at the same time, on the Pocket you have to tap to toggle the display.
Say you have recorded a long interview, with a duration of 12 min. And then in playback mode you want to jump 3:30 min into the interview. Tap the timecode on the display and it will change to clip duration. No move the time indicator to 3:30 min. Tap again to see the free run TC.
Or is there something I misunderstood?
Edit: Well actually there is a special rec run timecode in the Ursa Mini.
From the manual:
If you press and hold the ‘timecode’ button for five
seconds it will switch the camera into record run timecode and the timecode generator
will flash as well as the first two digits of the large timecode display. This indicates that
you are now editing your preset timecode and allows you to set a specific timecode
number for your preset timecode.
Pressing ‘reset’ at this stage will zero the timecode and then you can turn and press
the menu wheel to set the desired value starting with hours, minutes, seconds and then
frames. When you are happy with the timecode, press and hold the ‘timecode’ button
again for three seconds to set this as your preset timecode point. You will notice that
the timecode generator now shows this value and will only increment when the camera
is recording giving you continuous ascending timecode values. To switch your
timecode back to free running time of day code, press the ‘timecode’ and ‘hold’ buttons
simultaneously for three seconds.
Is it this what I marked in bold what you are looking for?
