how modify 'Video Frame rate' of a movie?
« on: June 25, 2014, 01:42:19 AM »
Hi,

I have a quicktime movie.

Running exiftool on it it shows:
Video Frame Rate                : 23.976


Is there a way to modify this value using exiftool to say 25?

(I only want to change the meta/header and not re-encode)

Thanks,
Adam

Adam,

Have you already tried the following?
exiftool -VideoFrameRate=25 your.mov

Note: please test this first on a copy of your file. And also notice that even if the update to the framerate value in the file is successful, it may still not have the desired effect…

Let us know if it worked  :)

No.  ExifTool has only limited write ability in QuickTime movies.  It only writes XMP plus a few date/time tags.

...where DIR is the name of a directory/folder containing the images.  On Mac/Linux, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).
