Excerpts :
Hi :)
After analyse a video file metadata with Digikam 6.0.0, it find a new field
displayed in file view : "dititalized date". It seems to display the same
date that "created date".
Anyway, this is what i see and understand about differents date fields in
list view :
<http://digikam.1695700.n4.nabble.com/file/t376394/gfH5Sh1.png>
1- File name : file is named with the actual date as soon as i start video
capture. It isn't a metadata but it is the real "taken date".
2- Last modified. File date attribute is writed at the end of the capture.
It isn't the good "date taken" because it is the "end" of the video, not the
"start". I think it have more sense to use "beginning date".
3- Created date : it is the end of the video but not the good : it has an
error of "one hour". I think it is about "GMT" ?
4- Digitalized date : new field sinc Digikam 6.0.0 but same problem that
created date (one hour less).
Because the "file name" is the only good "taken time", i only use it and not
the others fields. For that i just rename it to match my others file names
preferences (yyyymmddhhmmss). It is ok but when i explore my videos, i have
to sort them by "name", not by "date"...
then :
I made complete tests with my different video recording devices and
applications.
Issues (start video not used and difference of time) are present only with
my Android Devices, not with my "real" camera devices.
You can consult my sheet comparative here

I will share my video samples files soon when they will be uploaded.
Thanks
