Timestamps - sorting of Videos within photos
 
|
Hello everybody!
I realized that my self-made Videos with my small digiKam are not sorted correctly within my photos (I always have my images sorted by date). The videos usually appear grouped together at the right date, but not at the right point in the timeline. For example, I take a video, then a photo and then a video again; then they are not shown in this order, but the to videos are put side by side. The only way I can change this order and then put the video displayed at the right time is changing the time stamp manually to the correct time under "Image --> adjust time&date". Do you experience the same problem with Videos? And a related question: What exactly are these DigiKam-Timestamps? When I change the timestamps, neither exif, xmp, creation date or any one of these is changed. And where are the timestamps stored? Videos do not even have exif or xmp files... Thanks a lot for the help and advice micha ___________________________________________________________ Telefonate ohne weitere Kosten vom PC zum PC: http://messenger.yahoo.de _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |

Hello everybody! When files are copied off the camera the copied file will either have the creation date of the original or it will have the creation date of the copy (since the copy has just been created). I'm not sure what happens when you use digikam to import directly from a camera but if you use unix cp you need to use the "-p" option. Once you've got it copied without changing the date digikam will sort it properly but this is a bit of an unreliable operation because it's not using any embedded metadata. The first thing I use is the digikam rename tool to rename all the videos to include the date in the filename. At least then if the database is corrupted or the creation date is lost then you can reconstruct it from the filename. What we really need is for exiv2 to be able to read metadata from the videos. MP4 videos from an iPhone and AVCHD files from my Canon camcorder do have the date embedded as metadata but exiv2 does not understand how to read video metadata yet. I hope it's coming at some point. It would also be nice if digikam could read the orientation metadata from iPhone videos to understand portrait vs landscape.

My experience is, that Videos are sorted according to the date (creation date probably), but not according to the time. When I put a digiKam timestamp the photo is sorted correctly. But what are those timestamps? Does anybody have an idea. I guess they are saved in the DigiKam database and not with the file itself; is this correct? ___________________________________________________________ Telefonate ohne weitere Kosten vom PC zum PC: http://messenger.yahoo.de _______________________________________________ Digikam-users mailing list [hidden email] https://mail.kde.org/mailman/listinfo/digikam-users |
