Can BORIS software import the original video time ?

[EinatZ]

I started working with BORIS 8.0.10, I'm working on videos from Browning's camera traps. Is there an automatic way that the BORIS software can import the original time the video occurred? And so I can export the behaviors along with the original time of the video was shot to a CSV file.

Thank you, Einat

Hi,

I do not know the Browning's camera traps. How is the original time recorded?

When I download the videos from the camera they come as MP4 files. There is the date and the time the video was shot in the bottom right corner of the video (the data I wish I could upload automatically in the BORIS software),

Hi,

you can use the time offset parameter when creating the new observation. See https://boris.readthedocs.io/en/v7/#create-a-new-observation for details

Hi Olivier,

Thanks again for all your work on this project.

I have a related question. Specifically, it is related to the "Time offset" button within the "Edit observation" window. I understand that this "Time offset" would be very useful for, e.g., translating the timestamps of not-yet-coded events into actual clock time. In my case, however, events have already been coded before the time offset was defined. Is there a way to "shift" the time of all coded events to correspond with the offset defined in the "Edit observation" window, «after the fact»?

In the "Events-table", I see that it is possible to highlight all events (rows), click "Shift time of selected event(s)" and input the "Time value", i.e., the number of seconds which would correspond with the above-mentioned "Time offset". But when entering a Time value corresponding to a clock time, it seems like the events are shifted "so far" that they start after the video is finished. I believe this is the case, since the red flags / arrows denoting the events in the "Events-table" as they occur in the video, seem to disappear. Can you elaborate the difference between «Time offset» and «Time value»?

In any case, when having added smaller «Time offset», (i.e. "Time offsets" small enough that events are not skewed to the "outside" of the video) it seems that, when clicking events in the "Events-table", the video now jumps to the start of the video, instead of playing from the start of the event itself (or the specified "time offset for reposition"), if defined under "Preferences". Is this a bug, or is there something I am not seeing here?

should be fixed. please reopen if not
