Removing metadata for animated GIF creates non-animated GIF

Not sure whether this is a bug or a feature - but a bad surprise!

Here are the metadata from a random animated gif, via ExifTool:

Code: Select all

---- GIF ----
GIF Version                     : 89a
Image Width                     : 400
Image Height                    : 206
Has Color Map                   : Yes
Color Resolution Depth          : 8
Bits Per Pixel                  : 7
Background Color                : 127
Animation Iterations            : Infinite
Frame Count                     : 56
Duration                        : 2.24 s

I believe without these instructions one can not expect the image viewer to be able to display the animation.

I understand. BUT: the GIF is after the operation smaller than before - i assume it contains only frame 1. That means that not only metadata were removed but frames 2+ too. And this is not a wanted behaviour.

Sorry for my useless answer.

If I my asks, how did you delete metadata from the animated gif, using XnViewMP?

[tonifelfe]

Tools - Batch convert - Actions: Clean meta data - all checkboxes activated

[mudo_j]

This way, I can't get a working animation, even without cleaning anything.

Right. As a workaround i will exclude GIF files from my workstream. A better solution would work with animated GIFs correctly.
