fatal file handling error in LR 10 Classic

[Tobias98A4]

Hello,

I am using following Software:

LR Classic 10.0

CR 13.0

MacOS 11.0.1

When there are two files of the same name and different filetype, LT treats these two files as one file!?

e.g.: two files in one folder:

test.jpg

test.mov

LR only shows the video file but when you change the filename within lightroom, it changes both file names (without the extension).

This corrupts my whole catalogue! I tried this with different files and it is reproducable.

Post a bug report in the feedback forum if this happens and you have selected treat jpeg files next to raw files as separate photos selected in LrC preferences. See screen capture.

This checkbox seems to work for me, thanks! But in case you uncheck this, why is a video file treated as a raw file?

No idea since I do not use mov files., maybe another user can provide the answer. Is the jpeg captured while sorting the video?

"But in case you uncheck this, why is a video file treated as a raw file?"

Some cameras create JPEG "sidecars" to hold video metadata (similar to how a .xmp sidecar holds metadata for a raw).   Some of these cameras used the .jpg extension for these sidecars, and some used .thm, even though the file is a JPEG (e.g. Sonys).  I'm not sure why the cameras do this, since the Quicktime and MP4 standards fully support metadata, including XMP metadata.

Regardless, when Treat JPEG Files Next To Raw Files As Separate Photos is unchecked, LR treats X.jpg and X.thm as sidecars for X.mov and X.mp4 (and perhaps other video formats as well) and reads metadata for the video from them (e.g. capture date).  You can see that in the Metadata panel:

The name of the option is indeed confusing.  It would be more accurate to call it:

"Treat JPEG files next to raw files as separate photos, and treat JPEG and THM files next to video files as sidecars."

I think the Adobe product manager/developer responsible for this opted for short over accurate.
