Core Capabilities

• Clip Selection: Extract specific time ranges from videos
• Speed Control: Slow motion, speed up, or reverse
• Cropping: Resize and crop to any dimensions
• Text Overlays: Add captions, titles, or watermarks
• Effects: Filters, fades, color adjustments
• Optimization: Smart compression for target file size
• Batch Processing: Convert multiple clips at once

Quick Start

from scripts.gif_workshop import GifWorkshop

# Basic conversion
workshop = GifWorkshop("video.mp4")
workshop.to_gif("output.gif")

# With options
workshop = GifWorkshop("video.mp4")
workshop.clip(start=5, end=10)          # 5-10 seconds
workshop.resize(width=480)               # Resize to 480px wide
workshop.set_fps(15)                     # 15 frames per second
workshop.optimize(max_size_kb=500)       # Max 500KB
workshop.to_gif("output.gif")

Core Workflow

1. Load Video

from scripts.gif_workshop import GifWorkshop

# From file
workshop = GifWorkshop("video.mp4")

# With initial settings
workshop = GifWorkshop("video.mp4", fps=15, width=480)

2. Select Clip Range

# By time (seconds)
workshop.clip(start=5, end=15)  # 5s to 15s

# By time string
workshop.clip(start="00:01:30", end="00:01:45")  # 1:30 to 1:45

# From start or to end
workshop.clip(start=10)  # From 10s to end
workshop.clip(end=5)     # First 5 seconds

# Multiple clips
workshop.clip_multi([
    (0, 3),
    (10, 15),
    (20, 25)
])  # Concatenates clips

3. Adjust Speed

# Speed up
workshop.speed(2.0)  # 2x faster

# Slow motion
workshop.speed(0.5)  # Half speed

# Reverse
workshop.reverse()

# Boomerang effect (forward then reverse)
workshop.boomerang()

4. Resize and Crop

# Resize by width (maintain aspect)
workshop.resize(width=480)

# Resize by height
workshop.resize(height=360)

# Exact dimensions
workshop.resize(width=480, height=360)

# Crop to region
workshop.crop(x=100, y=50, width=400, height=300)

# Crop to aspect ratio
workshop.crop_to_aspect(16, 9)  # 16:9
workshop.crop_to_aspect(1, 1)   # Square

5. Add Text

# Simple text overlay
workshop.add_text(
    "Hello World!",
    position='bottom',
    fontsize=24,
    color='white'
)

# Text with timing
workshop.add_text(
    "Watch this!",
    position='top',
    start_time=0,
    end_time=3  # Show for first 3 seconds
)

# Multiple text overlays
workshop.add_text("Step 1", position='top-left', start_time=0, end_time=2)
workshop.add_text("Step 2", position='top-left', start_time=2, end_time=4)

# Caption bar
workshop.add_caption_bar(
    "This is a caption",
    position='bottom',
    background='black',
    padding=10
)

6. Apply Effects

# Color filters
workshop.filter('grayscale')
workshop.filter('sepia')

# Adjustments
workshop.adjust(brightness=0.1, contrast=0.2)

# Fade in/out
workshop.fade_in(duration=0.5)
workshop.fade_out(duration=0.5)

# Blur
workshop.blur(intensity=2)

7. Optimize for Size

# Target file size
workshop.optimize(max_size_kb=500)

# Quality settings
workshop.optimize(
    quality='medium',  # 'low', 'medium', 'high'
    colors=128         # Color palette size (2-256)
)

# Manual FPS control
workshop.set_fps(10)  # Lower FPS = smaller file

# Lossy compression
workshop.optimize(lossy=80)  # 0-100, higher = more compression

8. Export

# Basic export
workshop.to_gif("output.gif")

# With options
workshop.to_gif(
    "output.gif",
    optimize=True,
    colors=256,
    loop=0  # 0 = infinite loop, 1+ = loop count
)

# Export as video (for comparison)
workshop.to_video("output.mp4")

# Export frames
workshop.export_frames("frames/", format='png')

Presets

# Social media presets
workshop.preset('twitter')     # 512px wide, 5MB max
workshop.preset('discord')     # 256px, 8MB max
workshop.preset('slack')       # 480px, 5MB max
workshop.preset('reddit')      # 720px, optimized

# Quality presets
workshop.preset('high')        # High quality, larger file
workshop.preset('medium')      # Balanced
workshop.preset('low')         # Small file, lower quality

# Special presets
workshop.preset('thumbnail')   # Small preview GIF
workshop.preset('reaction')    # Reaction GIF (small, fast)

Advanced Features

Frame Extraction

# Get best frame (thumbnail)
best_frame = workshop.get_best_frame()
best_frame.save("thumbnail.png")

# Extract frame at time
frame = workshop.get_frame_at(5.5)  # Frame at 5.5 seconds
frame.save("frame.png")

# Extract all frames
workshop.export_frames("frames/", format='png')

Video Information

info = workshop.get_info()
print(f"Duration: {info['duration']} seconds")
print(f"Size: {info['width']}x{info['height']}")
print(f"FPS: {info['fps']}")
print(f"Frames: {info['frame_count']}")

Custom Filters

# Apply custom function to each frame
def custom_filter(frame):
    # frame is a PIL Image
    return frame.rotate(5)

workshop.apply_filter(custom_filter)

Concatenate Videos

workshop.concat([
    "intro.mp4",
    "main.mp4",
    "outro.mp4"
])

Optimization Tips

File Size Reduction

1. Reduce dimensions: Smaller = much smaller file
2. Lower FPS: 10-15 FPS is usually sufficient
3. Limit colors: 64-128 colors often looks fine
4. Shorter duration: Each second adds significant size
5. Use lossy compression: Small quality loss, big size reduction

Quality Improvement

1. Start with high-quality source: Better input = better output
2. Use 256 colors: Maximum palette
3. Higher FPS: 24-30 FPS for smooth motion
4. Avoid heavy compression: Keep lossy above 90

Size vs Quality Presets

Preset	Width	FPS	Colors	Use Case
reaction	256px	10	64	Quick reactions
low	320px	12	128	Basic sharing
medium	480px	15	256	General use
high	640px	20	256	High quality
max	Original	24	256	Best quality

Error Handling

try:
    workshop = GifWorkshop("video.mp4")
    workshop.clip(start=0, end=100)  # May exceed video length
    workshop.to_gif("output.gif")
except GifError as e:
    print(f"Error: {e}")
except FileNotFoundError:
    print("Video file not found")
