When LR 7.3.1 imports a Sony or Canon MP4, if the THM sidecar is also present, then LR doesn't read the dimensions of the video and display them in the metadata panel. It also doesn't read the capture time properly -- instead, it uses the MP4's file modification time as the capture time, and it appears to set the multiple internal catalog fields inconsistently, causing inconsistent sorting by capture date in grid view.
The problem appears related to the presence of the .thm sidecars created by the camera. If you copy the .mp4 files to your harddrive without the .thm sidecars and import from there, LR correctly reads the dimensions.
Using LR CC Classic 7.3.1. When I import a mixture of still and video files into lightroom and attempt to sort by 'Capture Time' the .ARW (sony raw) and .mov (video) are separated, but within their file extension, they are sorted correctly by capture time. If I edit capture time (Metadata>Edit Capture Time) and do not make any changes but select 'Change', then the file is placed in proper capture time sequence. This behavior has been observed by others via a conversation on photo.net.
This is a difficult issue when one is shooting with two different cameras with different extensions and one wants to sort all of the captured pictures in sequence or when there is a mixture of stills and video from the same camera.
Here is a link. Let me know if that works for you. There are 7 files: two ARW, followed by MP4 and THM and then two more ARW files. They are numbered sequentially as they were taken. The last image is a screenshoot showing the sort order with the .mp4 at the end and you can see it was sorted by capture time.
Steven, my initial analysis of this bug was incorrect. Please see the first post in the merged thread above -- LR is getting confused by the presence of the THM sidecar files.
If you copy the videos to your hard drive first, delete the THMs, and then import them into LR, LR should set the capture time consistently. Unfortunately, that capture time will be in UTC, not the local time. But you can use the Metadata > Edit Capture Time to shift all the videos by the appropriate number of hours.
I've been using Lightroom to import Canon 7D video files for about 8 years with no major issues. I just noticed that all videos I imported since mid-April have no meta data from the THM side car files - no date taken, no camera info, no exposure info, etc.. The previous import I did was in December 2017, and that sidecar information imported as usual. I didn't import any videos between December and April, so I don't know with which release the issue started, but I suspect 7.3.
Has anyone else been experiencing this issue, or have I done something to my setup? I am running Lightroom 7.3.1 on Mac OS X High Sierra 10.13.4, on a 2012 MacBook Pro.
This screen shot shows a May 2018 import with no sidecar metadata:
This screen shot shows a December 2017 import with all sidecar metadata:
I did try an import with "Embedded or Sidecar Previews" just to make sure that wasn't the issue, but that setting made no difference in the metadata imported.
Any suggestions would be greatly appreciated! Thanks! Jon
