Don't praise on that. Jam timecode that is inconsistent and goes out of sync every 40 minutes. Jammed once and never checking again and as we see turning VFR enabled modes hits pause of the timecode which makes unpredictable behaviours externally or internally timecoded. It can be useful if u use jut one profile on all of the cameras but this kills the customisation features, like the C1, C2, C3-1-2-3, profiles on the dial switch. Or after every shot whith VFR you have to go to the timecode setting and set timecode again on the current time to recorrect it.
This looks like just bad implementation and if it is possible to be fixed will be very convinient and make timecode reliable and usable, I wrote some mail to the support but since the responce was autobotic to check the firmware page I dunno if it will reach human eyes. (I installed latest firmware 1.2 as it was released of course). I always thought why the cameras don't have the option to name the files with the time they were started... for example 154302253.mp4 for hit record at 15:43:02:23, then inpoint on a timeline will be the filename, of course the software might not support that, but some script can do it.
