Why GIF? Typical GIFs are limited to 256 colors. Why not PNG,
which is full color, compressed and lossless? Or JPEG which is full
color and compressed even more? Ideally, there should be no new GIF
format files.<br>

<div>Hi,<br>
<br>
</div>
It would be very useful if Chimera (prob ChimeraX) was
able to save either single frames, or, preferably,
record movies in GIF format.<br>
<br>
</div>
This is not so much out of a desire to make animated gifs
(although these can be handy for presentations and use on
the web), but more because it makes it very easy to create
labeled movies in vector graphics programs (one can edit a
single frame in a vector graphics program and then insert
it and alter the duration in for example GIMP or similar),
which can then be easily converted back to mp4. Otherwise
adding labels and custom annotations to movies is a pain
for a novice like me, though if any one has any
suggestions for recommended software I'd love to hear
them! I've tried using iMovie and found it incredibly
frustrating for the kinds of simple things like to do -
adding labels, boxes, arrows etc to highlight specific
domains during a morph, for example.<br>
<br>
</div>
At the moment I make a movie in chimera and convert it to a
GIF using videoblend, edit in affinity designer and GIMP and
then convert back to mp4 using online tools, but a more
direct route would definitely be useful.<br>
<br>
