What it does

Ffmpeg Video Filters is an agent skill from benchflow-ai/skillsbench. Apply video filters - scale, crop, watermark, speed, blur, and visual effects

Its SKILL.md is about 870 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Media & Creative, covering Video production. It works with FFmpeg. The repository describes itself as: SkillsBench evaluates how well skills work and how effective agents are at using them. The licence is Apache-2.0.

Example prompts

“/ffmpeg-video-filters”

What it can do on your machine

Read from SKILL.md and the folder at commit 9a1f4dd. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:

Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ffmpeg Video Filters loads about 867 tokens when it runs. Until then it costs about 25 tokens; SKILL.md has 89 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~25
When it runs · the whole SKILL.md, loaded when a task matches: ~867

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Adjust brightness/contrast

Scaling

bash

# Scale to 720p (maintain aspect ratio)
ffmpeg -i input.mp4 -vf scale=-2:720 output.mp4

# Scale to specific width (maintain aspect ratio)
ffmpeg -i input.mp4 -vf scale=1280:-2 output.mp4

# Scale to exact dimensions (may distort)
ffmpeg -i input.mp4 -vf scale=1920:1080 output.mp4

# Scale with algorithm
ffmpeg -i input.mp4 -vf scale=1280:720:flags=lanczos output.mp4

Cropping

bash

# Crop to 16:9 from center
ffmpeg -i input.mp4 -vf "crop=1920:1080" output.mp4

# Crop with offset (x:y:width:height)
ffmpeg -i input.mp4 -vf "crop=1920:1080:0:0" output.mp4

# Crop from specific position
ffmpeg -i input.mp4 -vf "crop=800:600:100:50" output.mp4

Watermarks and Overlays

bash

# Add image watermark (top-left)
ffmpeg -i input.mp4 -i logo.png \
  -filter_complex "overlay=10:10" output.mp4

# Bottom-right watermark
ffmpeg -i input.mp4 -i logo.png \
  -filter_complex "overlay=W-w-10:H-h-10" output.mp4

# Center watermark
ffmpeg -i input.mp4 -i logo.png \
  -filter_complex "overlay=(W-w)/2:(H-h)/2" output.mp4

Speed Changes

bash

# Speed up 2x
ffmpeg -i input.mp4 -vf "setpts=0.5*PTS" -af "atempo=2.0" output.mp4

# Slow down 0.5x
ffmpeg -i input.mp4 -vf "setpts=2.0*PTS" -af "atempo=0.5" output.mp4

# Speed up video only (no audio)
ffmpeg -i input.mp4 -vf "setpts=0.5*PTS" -an output.mp4

Blur Effects

bash

# Blur entire video
ffmpeg -i input.mp4 -vf "boxblur=10:5" output.mp4

# Blur specific region (coordinates x:y:w:h)
ffmpeg -i input.mp4 -vf "boxblur=10:5:x=100:y=100:w=200:h=200" output.mp4

# Gaussian blur
ffmpeg -i input.mp4 -vf "gblur=sigma=5" output.mp4

Brightness and Contrast

bash

# Adjust brightness and contrast
ffmpeg -i input.mp4 -vf "eq=brightness=0.1:contrast=1.2" output.mp4

# Increase brightness
ffmpeg -i input.mp4 -vf "eq=brightness=0.2" output.mp4

# Adjust saturation
ffmpeg -i input.mp4 -vf "eq=saturation=1.5" output.mp4

Rotation

bash

# Rotate 90 degrees clockwise
ffmpeg -i input.mp4 -vf "transpose=1" output.mp4

# Rotate 90 degrees counter-clockwise
ffmpeg -i input.mp4 -vf "transpose=2" output.mp4

# Rotate 180 degrees
ffmpeg -i input.mp4 -vf "transpose=1,transpose=1" output.mp4

Multiple Filters

bash

# Chain multiple filters
ffmpeg -i input.mp4 -vf "scale=1280:720,crop=800:600:100:50" output.mp4

# Complex filter chain
ffmpeg -i input.mp4 -i logo.png \
  -filter_complex "[0:v]scale=1280:720[scaled];[scaled][1:v]overlay=10:10" \
  output.mp4

Fade Effects

bash

# Fade in (first 2 seconds)
ffmpeg -i input.mp4 -vf "fade=t=in:st=0:d=2" output.mp4

# Fade out (last 2 seconds)
ffmpeg -i input.mp4 -vf "fade=t=out:st=10:d=2" output.mp4

# Fade in and out
ffmpeg -i input.mp4 -vf "fade=t=in:st=0:d=2,fade=t=out:st=8:d=2" output.mp4

Notes

Use -vf for video filters
Multiple filters separated by commas
Use -filter_complex for complex operations
Overlay positions: W=width, H=height, w=overlay width, h=overlay height
Speed changes require both video (setpts) and audio (atempo) filters
