Activation
This is the description your AI agent reads to decide when to run this skill — the better it matches your request, the more reliably it fires.
Extract key frames (I-frames) from video files using FFmpeg command line tool. Use this skill when the user needs to pull out keyframes, thumbnails, or important frames from MP4, MKV, AVI, or other video formats for analysis, previews, or processing.Key capabilities
- →Extract I-frames from video files
- →Support for MP4, MKV, AVI, and MOV formats
- →Filter frames by type
- →Generate image sequences
- →Control output quality
How it works
It utilizes FFmpeg CLI filters or skip-frame flags to identify and export I-frames based on presentation timestamps.
Inputs & outputs
When to use ffmpeg-keyframe-extraction
- →Generating video thumbnails
- →Extracting video frames for analysis
- →Creating preview frames from MP4 or AVI files
About this skill
FFmpeg Keyframe Extraction
Extract key frames (I-frames) from video files using FFmpeg CLI.
Prerequisites
- FFmpeg installed and available in PATH
- Input video file (MP4, MKV, AVI, MOV, etc.)
Methods
Method 1: Select Filter (More Control)
ffmpeg -i <input_video> -vf "select='eq(pict_type,I)'" -vsync vfr <output_pattern>
Method 2: Skip Frame (Faster)
ffmpeg -skip_frame nokey -i <input_video> -vsync vfr <output_pattern>
Key Options
Option Description
-i <file> Input video file
-vf "select='eq(pict_type,I)'" Filter selecting only I-frames
-skip_frame nokey Skip decoding non-keyframes (performance)
-vsync vfr Variable frame rate, prevents duplicates
-q:v <n> Quality (1-31, lower = better, for JPEG)
-frame_pts 1 Use presentation timestamp in filename
Output Patterns
frame_%03d.png - PNG sequence (frame_001.png, frame_002.png...)
frame_%03d.jpg - JPEG sequence
frame_%d.bmp - BMP sequence
Examples
Basic PNG extraction:
ffmpeg -i video.mp4 -vf "select='eq(pict_type,I)'" -vsync vfr keyframe_%03d.png High-quality JPEG:
ffmpeg -i video.mp4 -skip_frame nokey -vsync vfr -q:v 2 keyframe_%03d.jpg With timestamps:
ffmpeg -i video.mp4 -vf "select='eq(pict_type,I)'" -vsync vfr -frame_pts 1 keyframe_%d.png
To specific directory:
ffmpeg -i video.mp4 -vf "select='eq(pict_type,I)'" -vsync vfr ./output/keyframe_%03d.png
## Notes
Method 2 (-skip_frame nokey) is faster as it skips decoding non-keyframes
Method 1 offers more filtering flexibility (can combine with other filters)
Keyframe frequency depends on video encoding settings
Use -vsync vfr to avoid duplicate frames in output
When not to use it
- →When extracting non-key frames
- →When video encoding lacks I-frames
Prerequisites
Limitations
- →Keyframe frequency depends on original video encoding
- →Requires FFmpeg installation
How it compares
It automates frame extraction compared to manually scrubbing video files to capture individual frames.
