How 3GP to Animated GIF conversion works
3GP probe and decode → stream-aware conversion → Animated GIF verify
Reading 3GP
3GP input reads unencrypted mobile-media containers with supported H.263, H.264, or MPEG-4 Part 2 video.
Creating Animated GIF
Animated GIF output removes audio and uses a generated palette with explicit resolution, frame-rate, and loop settings.
