When I drag a clip from a 7D, with the folder directory intact with .THM files, into CatDV the timecode is reading 23:15:15. When I use Log and Transfer in FCP, it says 22:15:15. The hour is off by one for every clip. I've ticked several preferences in CatDV on and off but no luck. Curious if anyone knows why this is occurring. I know that 7D's "timecode" is just time of day timecode.
Check the file in CatDV using the Media/File Info command. Does it have a timecode track? If so, both CatDV and FCP would use that. If not, then I'd expect FCP to show 0:00:00:00 and CatDV to use the time of day (according to the Rec Date/Camera Clock field) if you have the import option "Use time of day timecode" enabled in CatDV's preferences. One possibility might be that Log & Transfer is also reading the camera clock but is applying daylight savings correction.
