Extracting and removing Motion Photos from a Samsung jpg

[exiflover]

Hi,

I have a Motion Photo jpeg file and I'd like to produce two files from it:
1. A video
2. A photo (maintaining EXIF information apart from the video)

To extract the video I can do this:
exiftool -b -EmbeddedVideoFile file.jpg >video.mp4

But how can I extract just the photo, without stripping out all the other EXIF metadata too?

I tried this:
exiftool -EmbeddedVideoFile= file.jpg
but I get the error:
Warning: Sorry, EmbeddedVideoFile is not writable

Thanks

The EmbeddedVideoFile is in the JPEG trailer.  Try this to remove it:

exiftool -trailer:all= FILE
