Hi.

P4P

When taking photos in J+R (jpeg+raw) image format mode, the EXIF data reveals sometimes a difference in timestamp of 1 second. Since I use a script in post-processing to change the filename into someting including EXIF timestamp, I get dupes.

DJI_0001.JPG -> 20180508-195308_djip4p_[dji_0001].jpg
DJI_0001.DNG -> 20180508-195309_djip4p_[dji_0001].dng


Is there any way the get sync'ed timestamps for the same picture (jpeg and raw) on the DJI side (settings in App)?

Thanks,

Would you see any difference if using the EXIF field "Date/Time Original" / "Date and Time (Original)"?
I think you are fetching the file info times from the few i just looked at here.

Not sure how your script would result in dupes, rather the opposite but i don't know your script.

Your answer triggered the solution.

There is ...
DateTimeOriginal (%Xdot)
DateTimeDigitized (%Xddt)
DateTime  (%Xdtt)

I used DateTimeOriginal, which resulted in different time.
DateTime did the job!
Always the same time.

Many thanks!

Nice to hear you found a solution
Strange enough when i look at my own pic's only the Original has the same timestamp for .DNG and .JPG, the other time fields found differ a few seconds.

If not tested already you might also check out how it look on shots taken with EAB and eventually Pano pictures.

Yes, you are right. Another software also shows that DateTimeOriginal are identical (exiftool.exe).

Anyway ... I found the solution how to obtain the same date/time.

BTW ... I use a P4P. Can this one take AEB or pano pictures ?!?!

Yes it sure can beside of the spelling, AEB

AEB has afaik been there the whole time, Pano was added during the Christmasdays, some later on the +
You would need to have firmware 1.5.600 on the AC and using App v. 4.1.20 or higher, then it should look like in this picture at the Photo settings.

Just tested ...

AEB pictures behave just like single shots. The Data/TimeOriginal spacing is 1 or 2 seconds. They are also saved in the 100MEDIA folder on the SD card. Hence, all like expected.

Same for Pano pictures. Spacing is 1 or 2 seconds, but the pictures are stored on the SD card in the folder PANORAMA/100_xxxx, ...

Good to hear, when doing scripting like this it is better to have it tested on all possible situations right away than later end in a disaster if it misbehave unnoticed due to a different situation.
Then there's the burst mode, if also your script end up doing on those what you made it to do, you should be confident all would be in place to handle what ever you end up doing out in the field.
