Lightroom Classic: Read and write video metadata into video or sidecar

The new Video part is great! I really like the previews.It is a great addition to sort and tag your video's. Only one problem:The tagging system doesn't work properly, it doesn't store the tags in the video-files like it is possible with the photo's. I hope this will be working in the Final.

There will be some bug fixes in this area in the next release update (lr 6.4), particularly for customers who shoot videos using Canon, Fuji and Panasonic cameras. There is no industry standard to store EXIF in the .mov/.mp4 video file formats.

Vendors such like Canon, Fuji and Panasonic decided to store EXIF in their own proprietary formats for videos. It took a while for the Lightroom team to talk to each vendors to get their blessing to expose those EXIF video metadata.

Around the time before the release of the 5D3, Canon stopped creating the .thm files which had a lot of useful metadata. It will be really helpful to be able to have access to that information again.

While your at it would you please add some code to correctly evaluate Quicktime date/time that include a timezone offset. It seems that all iPhone videos use the UTC date/time with a timezone offset. Lightroom currently ignores the timezone and uses the raw UTC data/time which messes up capture time sorts and file renaming if based on date/time.

It seems logical that if the date/time has an timezone offset that Lightroom should use that to calculate the internal date/time. If the internal date/time does not have a timezone offset then default to the local system timezone.

tks,

"There is no industry standard to store EXIF in the .mov/.mp4 video file formats."

I'm confused by this -- the QuickTime and MPEG-4 standards do define how to store metadata. In addition, Adobe's "XMP Specification Part 3: Storage in Files" (July 2010) explicitly defines how to embed arbitrary XMP metadata within dynamic media formats like QuickTime (.mov) and MPEG-4 (.mp4) and in video package formats like AVCHD, Panasonic's P2, and Sony's formats.

Nothing would stop Lightroom from using the exact same approach it uses for industry-standard image formats (TIFF, JPEG, PNG) and proprietary camera raw formats:

- For industry-standard formats (e.g. QuickTime and MPEG-4), if a metadata field is defined by the standard, write back changes to that field. Otherwise, write the field to embedded XMP.

- For proprietary formats, read field values from the format but store changes in an XMP sidecar.

What seems to be odd though is that the same vendor (Adobe) seems to have a product that handles writing video metadata just fine. I regularly use Adobe Bridge to do this. I can't say for sure it works with all vendors but I haven't had problems with video formats (.wmv, .mov, .mp4) from Apple, Canon, and Nokia as well as those videos created with Adobe Encoder. Why that can't same functionality be made available in LR beats me. If there are some "purist" objections because of "non-standard" methods, make it optional.

I was referring to read/writing EXIF metadata standard for video.

Can you say more about what you mean by "EXIF" here? Technically, the EXIF specification doesn't say anything about video, just still images and audio.

Do you mean that there isn't a single, widely accepted specification for metadata fields that would be populated by video-capturing cameras (exposure, lens information, frame rate, etc.), as there is for still cameras?

Hi John, Canon for example provides a lot of useful metadata about the video via the .thm sidecar file (really a JPEG thumbnail). Lr really depended on the presence of .thm to get most of the video metadata, such as camera make, model, lens info and capture time etc. Without the .thm and without Lr being able to understand the proprietary EXIF format stored in the videos generated by Canon, Fuji or Panasonic camera (the only camera vendors that does this as far as we know), Lr used to drop the video metadata on the floor.

The fix would be at least be able to read those video metadata as much as the vendor willing to support for such scenarios. The writing of video metadata is another beast. LR is certainly not going to support writing back the metadata in the proprietary EXIF blocks.

Understood. That's why the same approach used for proprietary raw files could apply to videos: read the metadata from the various industry standard and proprietary formats, write back to industry standard formats, write back to sidecars for proprietary formats.

>If exiftool can do it Adobe surely do a better job
That is a myth :-). Big companies like Adobe needs to follow the rules. Adobe cannot reverse engineer some other companies proprietary implementation without the legal clearance and cooperation from the respective vendors. There is a very big difference here.

Oh, the irony... Each comment here begins with the person's icon, their name, and the number of days/months/years ago the the comment was posted.

And if you roll over the "4 years ago" text, it will then show you the specific date and time that the comment was posted. Go ahead, give it a try...

For instance, go to the original post at the top. It currently says "4 years ago." The rollover text specifies the date as being January 18, 2012. But I'm typing this on Dec 18, 2015. So, the comment is NOT from "4 years ago" -- sure, a month from now it will be, but it's not, now.

Check the others -- on some, the time differential is nearly four months.


So really... what is it about Adobe that they should be challenged by time stamps?

This reply was created from a merged topic originally titled Read/write metadata from file doesn't work for videos.

Lightroom doesn't allow users to read or write video metadata from or back to a file. This is a problem, especially since videos I imported a while ago aren't displaying the camera make and model.

I'd like to read the metadata from the video files, but Lightroom doesn't allow me to do so. Instead, I need to remove these video files from my library and import them again, losing the rating, labels, and location metadata I had already applied to them.

There's no reason why this feature should be disabled for video files. Also, it should be possible to write video metadata to sidecar .XMP files.

I'd like to add my support to the idea that Lightroom add the ability to export metadata to a sidecar for movie files. Bridge seems able to save metadata in some movie files directly, but a sidecar file would be better for my needs. If this is a possible addition to Lightroom, I'd really like to see it added in soon.

This reply was created from a merged topic originally titled Is there a way to use Lightroom keywords in Premiere Pro?.

I use Lightroom to import all my photos and videos onto my computer and I'm finding the lack of communication between Adobe programs rather frustrating. The keywords function in Lightroom works well within Lightroom, but if I tag videos within LR and then try to use the same videos in Premiere Pro the keywords don't carry across, and this really slows down my workflow in terms of video editing.

For videos (and photos too) we need a keywording system that applies the keywords to files at the root level so they're accessible within any Adobe program. It would save so much time having to label footage every time I use particular clips in a new Premiere Pro Project, and also make cataloguing of footage so much easier than the mess it is now.

LR 7.4 added support for HEIF / HEIC photos, whose format is based on the same Quicktime format as MP4 videos.  Even though that format supports writeable metadata, Adobe decided to write the metadata for .heic photos to .xmp sidecars.  Too bad they didn't write the few extra lines of code to do the same for videos.

This reply was created from a merged topic originally titled Lightroom: Read and Write Metadata to Videos.

Lightroom Classic does not write metadata to videos such as keywords and captions. Whenever I come across a video I want to add a keyword to in Lightroom, I have to move it to an empty folder so that Bridge doesn't have to generate thousands of previews (something it doesn't do anywhere near as fast as LR) and then keyword the video. Since Lightroom can't read updates, I now have to re-import the video. This takes up extra time. Can you let LR read and write metadata for videos, like you do for photos? Even if you export a video in LR and check the box that says to write keywords to the video, keywords aren't written to the video. Just found that out today, as I continued my search for a solution of LR changing file's creation dates whenever I keyword or caption photos and save the metadata.

It would be great that at some point Adobe creates a systematic approach to embbed metadata in video the same way it does with images.  It is so easy with images . You can enter the metadata in dozen of programs and each can read was written by other. In video this is not possible and you have the create CSV files but after trying different option I have seen this is a complicated route and not standardized at all. I really hope that at some point IPTC data that can be read by any program can be done in video the same way it is done with still images.

People on this forum sure love bugs, requesting more all the time. Increased complexity = increased bugs, just a fact of life. If we want Lightroom to become more reliable, we need to ask Adobe to remove all the features that have no business in a photo editor (e.g. video support, book creation, slide shows, web support...) and multiple ways of doing the same thing (color, numeric and star ratings which can be handled better with keywords). 

 

Perl, the programming language, eventually became unusable. As Larry Wall, the creator of the language, said; Perl is bad because people wanted it bad. They featured it to death. 

 

Lightroom users are doing the same thing. 

 

If we are not going to start helping Adobe reduce complexity then all bug reports should be automatically deleted.

You are right that complexity is every software big enemy but think that if you have to use 5 different software instead of one you are not getting rid of complexity but instead increase it even more. 

So people that shoot video and photos should manage their files with two different applications. don't know if this would be successful. Another competitor would come and make it all at once possible and users of both assets would say goodbye to Adobe. No easy way out to the complexity conundrum

5 features each in 2 separate applications has many fewer defects than 10 features in a single application. Orders of magnitude fewer bugs. If you want to do the math:

 

2 apps with 5 features is 2*((4^5)-(2^5)) level of complexity = 1,984 

 

1 app with 10 features is (4^10)-(2^10) level of complexity = 1,047,552 

 

In scientific notation replace ^ with **. 

 

The ratio is the increase in complexity = 528 or the increased likelihood of defects. 

 

This is one of the reasons that traditional monolithic COBOL programs are full of bugs while modular code is cleaner. Not perfect but much cleaner.

The goal of Classic Lightroom has always been to offer a single environment covering the typical photographic workflow instead of being forced to string together a workflow from a menagerie of best of breed apps. Since DSLRs produce videos, it has included video support. Since photographers sometimes do slideshows, it includes a slideshow feature. Etc. Since keywords are supposed to be for analysing and categorising, and ratings are an important tool for evaluating and quickly filtering photos, it doesn't confuse the two industry-standard features. Of course Lightroom should save/read metadata back to video.

I can happily geotag any video in my LrC 10.3 library but exporting it (quality max, not original file) does not actually include the geotags in the exported file.  Confirmed with exiftool and Apple Photos.

If this is unexpected, what info do you need from me?  Happy to follow up with example files, debug logs, and such, if this is actually unexpected behavior and not a previously-known problem.

Thanks!

Brian, as you can see from the merged thread, LR has never been able to write video metadata since video was introduced in LR 3. In general, LR's support for video is minimal at best.

I would like to have the ability to Automatically write metadata to video files. There lots of digital cameras which have the ability to capture video files.
