Best practice for storing and tagging movies

[Simon Cropper-4]

*** Anyone have any ideas thank you? Not sure others received notification a few days back as I have recently changed my email ***

What is the current best practice for managing movies with digikam. I could not find anything specific on the online manual.

On my system -- Ubuntu 14.04 64bit with Mate Desktop -- the videos can be run ok and each video has a thumbnail. In particular I am interested in storage of metadata. I don't want to store metadata in the video file but in an associated XMP file.

If I tag a video however and open the associated XMP file the tags are not present. I have a message <?xpacket begin="" id="W5M0MpCehiHzreSzNTczkc9d"?> instead. The metadata is stored but only in the database. There seems no option for exporting the metadata to the XMP file. I don't mind having the data in the database but want a complete XMP file as an additional safety measure. In the past with my images if the database becomes corrupt I create a new database and import the XMP data back into the database. When tagging videos I would not be able to do this.

Any feedback would be appreciated.

video management is very different from photo management. All what
Digikam can do is read videos eventually. I don't think he would have to
do anything else.

I know of no standard to do so - but would be glad to prove wrong, so
it's pretty useless

(I have seen your first post, but expected also an other answer)

I don't see how it differs. Author, time taken, tags. I would not expect digikam to import any data from the video just save any user created metadata to an associated XMP file. Just like what people do when they create a JPG of the video and associate the image with that video.

What's wrong with just saving the database data (e.g. tags) to the file in an image format rather than a video format. I agree that there is currently no standard but who cares as long as the data can be exported and imported.

Thanks for letting me know, I thought it got lost.

Hi Simon,

what digiKam, libkexiv2 and exiv2 versions do you have installed?
I have the strong feeling that you need (at least) a recent exiv2
(v0.25) that supports video files.

Best regards,
Andreas

we can edit a photo in digikam, but almost no video source is usable as
is, it *needs* editing (at least cut bad parts) end encoding

tagging is a hard work, if one can't reuse it everywhere, it's useless

That should be OK. Did you check XMP sidecar options in digiKam's
metadata settings?

Yep, everything OK.

Can save data to image XMP sidecar ok; but as explained in the OP when saving tags to XMP sidecar for video all I get is a message <?xpacket begin="" id="W5M0MpCehiHzreSzNTczkc9d"?> saved to file instead. I presume this is just a link to the position in the database.

In digikam, the tags are present in the database. If I tag a video and filter on its tag it is found. Just wondering why the data is not stored to the XMP file like everything else.

I also not that the XMP tag under the metadata section of the right sidebar has a bunch of data listed. Codec, BitDepth, Camera Used, etc; so digikam can see and list the basic video data. It just does  not save it to the XMP file.
