Title: i do not see the focal length of a .mov file
Post by: alvaro562003 on February 01, 2017, 11:03:00 AM
Hello all,

i want to use exiftool to extract the focal length of a .mov file.

When i do simply in a windows 10 cmd "exiftool pathname" i got a lot of information BUT no focal length. It seems strange for me.

The .mov file came from an iphone 6.

Does someone have an explanation ?

Thank you very much and sorry if my question is naive.

Focal length could be changing during a video, so it doesn't really make much sense for this to be stored as file-level metadata (which is what ExifTool extracts).  Having said this, some cameras do store this information (presumably the focal length at the start of the video), but apparently not the iPhone.

It may be possible that some dynamic information is embedded in the video stream of MOV files, but ExifTool doesn't currently extract this.

Thank you that's what i feared, but now i am (nearly) sure
So i will use "Make" & "Model".

Is there a way to retrieve ONLY the field "Make" ?
