How can i read 'focallength' in Fujifilm's video?

[Jhe]

In Fujifilm's mov video, max/min focallength can be found, but not focallength.

Presumably Fujifilm don't consider it to be meaningful as it could change during the video clip.

(Not in this case of course but it could change if you were using a zoom lens).

Thanks for your reply.Canon,Nikon,and Panasonic are all recorded. It should be the focal length at the beginning of the video.

This varies by models. My older model Nikon (d5100) doesn't save this value.

Just because a tag exists, it doesn't mean that it will be used in all cameras.

Yes.I search the focallength data all the file and confirm there is no data in video.
