Do I need FFmpeg installed?

Yes. This tool generates the FFmpeg command for you to run locally. Install FFmpeg from ffmpeg.org or via your package manager (e.g. brew install ffmpeg on macOS, apt install ffmpeg on Ubuntu).

What is the two-pass palette command?

The two-pass method first generates an optimal color palette from the video frames, then uses that palette to encode the GIF. This produces significantly better color quality and smaller file sizes compared to the one-pass command.

What FPS should I use?

For smooth motion use 15–24 FPS. For compact file size with acceptable motion use 10–12 FPS. GIFs above 24 FPS offer little visual improvement while bloating file size significantly.

Why is my GIF so large?

GIF file size grows with width, FPS, duration, and scene complexity. Try reducing the output width to 480px or below, lowering FPS to 12, or trimming the duration to under 5 seconds.

Can I use this for MP4 or other formats?

Yes — the generated command works for any video format FFmpeg supports (MP4, AVI, MOV, WebM, etc.). Just change the input filename extension.

What does the -ss flag do?

The -ss flag sets the start time. Placing it before -i (input) uses fast seek; placing it after -i uses accurate seek. This tool places -ss before -i for speed, which is standard practice for GIF generation.

Enter your MKV clip parameters and get a ready-to-run FFmpeg command to convert it to an optimized animated GIF.

Conversion Parameters

Input filename

Any FFmpeg-supported format works (MP4, AVI, MOV, etc.)

Output filename

Start time

Format: HH:MM:SS or total seconds (e.g. 65)

Duration (seconds)

Recommended: 1–10 seconds for compact GIFs

Frame rate (FPS)

Output width (px)

Estimated GIF size: — Rough estimate; actual size depends on scene motion and color complexity.

One-Pass Command (quick, lower quality)

Click "Generate FFmpeg Command" to see output here.

Two-Pass Palette Command (recommended — best quality)

Click "Generate FFmpeg Command" to see output here.

Then run pass 2:

Quick Tips

1 Install FFmpeg: brew install ffmpeg (macOS) or apt install ffmpeg (Ubuntu).
2 Run the command in the same directory as your input file, or use full file paths.
3 The two-pass palette method produces richer colors and smaller file sizes — always prefer it for final output.
4 Keep GIFs under 5 seconds at 480px wide for best compatibility on social platforms.

Summary

Enter your MKV clip parameters and get a ready-to-run FFmpeg command to convert it to an optimized animated GIF.

How it works

Enter your input MKV filename (e.g. clip.mkv).
Set the start time in HH:MM:SS or seconds format (e.g. 00:00:05 or 5).
Set the clip duration in seconds (e.g. 3 for a 3-second GIF).
Choose the output frame rate (FPS) — 10–15 is typical for smooth, compact GIFs.
Set the output width in pixels; height scales automatically.
Copy the generated FFmpeg command and run it in your terminal.

Use cases

Create animated GIFs from screen recordings or gameplay footage.
Extract a looping preview clip from a tutorial or demo video.
Generate reaction GIFs from movie or TV show clips.
Produce lightweight GIF animations for documentation or blog posts.
Convert short MKV highlight clips to shareable GIF format.
Test FFmpeg parameters before batch-processing a large video library.
