Hi,
I'm new to this tool. I used an iPhone to record video, then used ffmpeg to extract every 10th frame. I want to add FOV info so I can use the images to generate 3D surfaces with Regard3D. When I try:
exiftool -FieldOfView=50 landscape.001.jpg
I get:
0 image files updated
1 image files unchanged
and no FOV info was added. What am I doing wrong?
Exiftool doesn't have definitions to write FieldOfView. Check the Tag Names subpage (https://exiftool.org/TagNames/) for that particular tag to see what tags are writable/not writable.
