GifHorse - Dialogue Search & GIF Creator
Create reaction GIFs from your video library by searching dialogue and adding timed subtitles.
What GifHorse Does
- •Transcribe videos - Extract dialogue with timestamps by downloading subtitles, using local .srt files, or Whisper AI
- •Search dialogue - Find quotes across your entire video library instantly
- •Preview clips - See exactly what will be captured before creating the GIF
- •Create GIFs - Generate GIFs with perfectly timed subtitles and optional watermarks
Setup
First Time Setup
- •Install gifhorse (via install button above)
- •Install FFmpeg-full for subtitle rendering (via install button above)
- •Transcribe your video library (downloads subtitles automatically):
cd ~/gifhorse && source venv/bin/activate gifhorse transcribe ~/Movies
The gifhorse command must be run from within its virtual environment. You can activate it with:
cd ~/gifhorse && source venv/bin/activate
Or use the activation helper:
source ~/gifhorse/activate.sh
Available Commands
Transcribe Videos
Extract dialogue from your videos (one-time per video):
# Default: downloads subtitles from online providers (fast, recommended) gifhorse transcribe /path/to/videos # Use only local .srt files (no downloading, no Whisper) gifhorse transcribe /path/to/videos --use-subtitles # Use Whisper AI (slow but works for any video) gifhorse transcribe /path/to/video.mp4 --use-whisper
Download Subtitles Only
Download .srt files without storing in the database:
gifhorse fetch-subtitles /path/to/videos gifhorse fetch-subtitles /path/to/videos --skip-existing
Search Dialogue
Find quotes across your entire library:
# Basic search gifhorse search "memorable quote" # Search with surrounding context gifhorse search "memorable quote" --context 2
Preview Before Creating
See exactly what will be captured:
gifhorse preview "memorable quote" 1 gifhorse preview "quote" 1 --include-before 1 --include-after 1
Create GIF
Generate the GIF with subtitles:
# Basic GIF gifhorse create "memorable quote" 1 --output reaction.gif # High quality for social media gifhorse create "quote" 1 --width 720 --fps 24 --quality high # Include conversation context gifhorse create "quote" 1 --include-before 2 --include-after 1
Check Status
# See transcription stats gifhorse stats # List all transcribed videos gifhorse list
Timing Options
Control exactly what gets captured:
- •
--include-before N- Include N dialogue segments before the match - •
--include-after N- Include N dialogue segments after the match - •
--padding-before SECS- Add buffer seconds before dialogue starts (default: 1.0) - •
--padding-after SECS- Add buffer seconds after dialogue ends (default: 1.0) - •
--start-offset SECS- Manual adjustment to start time (can be negative) - •
--end-offset SECS- Manual adjustment to end time (can be negative)
Important: For reactions after dialogue, use --padding-after instead of --include-after. The include-after option captures ALL time until the next dialogue segment (could be 30+ seconds!).
Quality Options
- •
--quality low|medium|high- Color palette quality (affects file size) - •
--fps N- Frames per second (default: 15, use 24 for smooth) - •
--width N- Width in pixels (default: 480, use 720 for HD) - •
--no-subtitles- Create GIF without subtitle overlay
Note: All GIFs automatically include a subtle "gifhorse" watermark in the bottom-right corner.

Tips & Tricks
- •Always preview first - Use
previewto verify timing before creating - •Default downloads subtitles - Just run
gifhorse transcribeand subtitles are fetched automatically - •Watch file sizes - High quality + long duration = large files (20s can be 20+ MB)
- •Padding vs Include - For reactions, use
--padding-afternot--include-after - •Search with context - Add
--context 2to see surrounding dialogue
File Size Guide
- •Low quality, 10s, 360p: ~1-2 MB
