Gif creation I don't believe is really on-topic for Super User. I would suggestion looking at either:
Graphic Design:
Graphic Design is for questions targeted toward 2D design
professionals, students, and enthusiasts.
This includes questions about:
- Graphic arts theory and history; "Why" we do what we do and not necessarily the "how" in logo design, fonts & typography, visual communication
- Web design
- Layout and printing
- Illustration
- Digital media
Examples: video, Adobe Flash
Note: This site may be more about the "Why" of things, than the actual "How". For both this and the other site I would review the questions being asked there, and even ask on their meta site if the question is appropriate.
or
Audio-Video Production:
The Audio-Video Production Stack Exchange is for engineers, producers,
editors, and enthusiasts spanning the fields of audio, video, and
media creation.
If you have a question about
- broadcast, film, audio, music, or location recording techniques
- editing, mixing, mastering, and distribution
- post-production techniques
- signal processing in a production context (for highly technical questions about digital signal processing, please visit Stack
Exchange's DSP site)
- asset management, media, and file formats
