Hello
I would like to extract 'zoom' information (focal length) from a .mts video file on a per second basis so that this can be added to extracted 1-second frames for calculating field of view.
I can get gps data etc with the below .. but the tag $FocalLength returns no result. Is this information stored in .mts files and can it be extracted by ExifTool?
exiftool.pl -ee -p "$gpslatitude, $gpslongitude, $gpstimestamp, $DateTimeOriginal, $FocalLength" -T -n 00023.mts>out.txt
Thanks
Jock
If there is no focal length reported when you run e.g. exiftool 00023.mts then it is not stored in the file (at least not in a tag known to exiftool). You could try adding -u or even -U to the exiftool command to let it extract unknown tags and see if you recognize a tag that might be the focal length (if so, please report here so Phil can add it).
