When I import photos and video using lightroom, I rename all my files based on date and time using a YYYYMMDD_HHMMSS format. For example:
This works perfectly for photos. That is, the (LR renamed) filename reflects the time the photos was taken (I suppose this is the "capture time"). However, the video time is totally wrong. For example, a video taken at 7PM gets renamed to something corresponding to 1AM.
I notice the following:
- Date/time based renaming of this particular iPhone 4S video works properly in other applications (e.g. Dropbox and PhotoMechanic)
- The resultant filename in LR4 appears to correlate to "Date Time Digitized", which in my case does not reflect when the video was actually taken (I'm not sure if it should or not, I'm only saying that it does not).
Is this expected behavior from LR4?
The behavior I'm seeing means that I have to use yet another application (e.g. PhotoMechanic or other) on the front-end of my workflow (before LR) in order to ensure video files are named "correctly". This is obviously not the desired solution, I'd prefer to do the renaming inside LR at the time of import since it provides a function for precisely this purpose.
Any comments appreciated.
I've got lightroom importing to folders named after the date, and occasionally it puts videos (avchd .MTS files) into folders for the day after they were taken. Occasionally splits a group of videos taken on the same day between two different folders for different days. Not sure what the trigger is for this, but wonder if it's a related bug?
This is a huge problem, and has existed since Lightroom 3. It basically makes LR3 and 4 useless for managing video files if you do it by date. Windows 7, for free, does a much better job.
The basis of the problem, from what I have been able to work out, is if the video does not contain a specific 'Date Taken' (or whatever*) value, then LR3 and 4 use the 'Date Created' as the time of the video. This is useless, as (in Windows anyway) that is generally the time the video was copied to your machine or HDD, rather then when it was taken.
That I think is the basics, but it gets worse and more complicated. Sometimes it seems to use GMT (as opposed to your local time). Sometimes it will change the time depending of whether or not you have daylight savings enabled in your camera. I spent a couple of hours testing, and with all my cameras set to the correct local time, I could get 7 different LR 'Capture Time' with 7 different cameras. Its a bad joke.
The very very very very easy solution would be to have LR just use the 'Date Modified' time instead of 'Date Created' or whatever they use now. Thats what Windows 7 and a whole bunch of other programs use by default. But a number of us have been raising this since LR3 beta, and have been systematically ignored.
And its why I dont use Lightroom to manage my videos.
I agree that video needs full LR support for metadata. Please add your vote and opinion to this topic in the LR feedback forum, Adobe's preferred forum for getting feedback:
In the meantime, I still use the Any File plugin to manage video files; this gives me full metadata capabilities.
I shoot AVCHD on a Canon HFS20, and when I import the .mts files to LR4, the metadata has no Capture Date, so LR sorts by Date Created (i.e., when I downloaded to the computer). A fix that seems to work, however, is to select a batch of videos that have been imported, select "Edit capture time" from the "Metadata" tab, accept the default selection of "Adjust to specified date and time," and click "Change All." Even though the selected date will show the capture date for the last selected video, it actually sets the Capture Date in the catalog metadata for each video to the right data and time (presumably based on the file's Date Modified but maybe based on some other metadata in the .mts file).
That's a pain, and it's no good if you actually want to set all the videos to the same date (which is what this function would seem to do), but so far it works for me even when the selected videos have a range of dates.
Of course, you still can't write that metadata back to an XMP file, but at least it's in the catalog for your clips.
Read through the discussion here and investigated further to find a solution that would work for me.
The issue, as reported, is that LR4 uses a video file's modified date/time when renaming. So the solution that worked for me was to download Attribute Magic Free and to change the modified date of my video files to the date the video was actually taken on. When renaming in LR4 now, the video files are correctly named - I rename my files: YYYY-MM-DD <sequence within the day>.* i.e. 2012-10-02 016.avi.
Hope this helps.
