### Examples
```bash
# Basic conversion with 15 keyframes
mime_mp4_gif.sh -k 15 video.mp4
# Fast animation with 50ms per frame
mime_mp4_gif.sh -k 20 -d 50 video.mp4
# Use sinusoidal transition with center-peak distribution
mime_mp4_gif.sh -t sinoid -s center-peak -k 20 video.mp4
# Apply psychedelic magic with fibonacci distribution
mime_mp4_gif.sh -m psychedelic -s fibonacci -k 13 video.mp4 trippy.gif
# Complex: 3 schedules with cubic interpolation and edge glow
mime_mp4_gif.sh -i 3 -t cubic -s front-load -m edge-glow -k 30 video.mp4
```
Usage: mime_mp4_gif.sh [OPTIONS] INPUT_FILE [OUTPUT_FILE]
Convert MP4 videos to animated GIFs with advanced frame extraction algorithms.
Arguments:
INPUT_FILE Input MP4 video file (required)
OUTPUT_FILE Output GIF file (optional, defaults to INPUT_FILE.gif)
Options:
-k, --keyframes N Number of keyframes to extract (default: 10)
-d, --keyframe-duration MS Duration of each frame in milliseconds (default: 100)
Valid range: 1-30000 ms
Lower values = faster animation
Higher values = slower animation
-i, --input-schedules N Number of input schedules (default: 1)
1 schedule = entire video duration
N schedules = divide video into N segments
-t, --transition TYPE Interpolation function for frame timing
Available: linear sinoid cubic quadratic exponential bounce elastic
(default: linear)
-s, --schedule TYPE Algorithm to distribute keyframes across schedules
Available: uniform front-load back-load center-peak edge-peak fibonacci golden-ratio
(default: uniform)
-m, --magic TYPE Apply magical effects to the GIF
Available: none psychedelic dither-bloom edge-glow temporal-blur chromatic-shift vaporwave
(default: none)
-v, --verbose Enable verbose output
-h, --help Show this help message
