Video

Process, edit, and optimize videos for any platform with compression, format conversion, captioning, and repurposing workflows.

Security Scan

The skill is internally consistent: it documents FFmpeg-based video workflows and only requires local ffmpeg/ffprobe (optional local tools for transcription/upscaling) and contains no hidden installs, credentials, or external endpoints.

Purpose & Capability

Name/description match the claimed requirements and artifacts: the skill is an instruction-only FFmpeg workflow guide and declares ffmpeg/ffprobe as required and whisper/realesrgan as optional. Nothing requested (no env vars, no config paths) is unrelated to video processing.

Instruction Scope

SKILL.md and supporting files limit actions to processing user-supplied files with FFmpeg and optional local tools (Whisper, Real-ESRGAN). The instructions do not reference credentials or remote uploads. Minor notes: many example commands assume a Unix shell (/dev/null, for-loops, bc, echo) which can be non-portable on Windows; some workflows reference optional external tools (whisper, realesrgan) that, if installed, will run locally — the skill does not provide install steps for them.

Install Mechanism

Instruction-only skill with no install spec and no code files — nothing is downloaded or written to disk by the skill itself. This is the lowest-risk install pattern.

Credentials

No environment variables, credentials, or config paths are requested. Optional tools are explicitly labeled optional and appropriate for the stated features (local transcription/upscaling).

Persistence & Privilege

The skill is not always-enabled and does not request persistent or elevated privileges. It does not modify other skills or system settings according to its documentation.

Assessment

This is a documentation-only skill that provides FFmpeg commands and workflows and appears to do only what it says: operate on files the user explicitly provides. Before installing/using it: ensure ffmpeg and ffprobe are installed from trusted sources; be aware optional tools (Whisper, Real-ESRGAN) are local and must be installed separately if you want those features; many example commands assume a Unix shell—adapt them on Windows; review any commands before running them (they will execute on files you provide). If you prefer to avoid any chance of local execution by an autonomous agent, keep the skill user-invocable only and do not grant it unattended execution privileges.

Requirements

Required:

• ffmpeg / ffprobe — core video processing

Optional:

• whisper — local transcription for captions
• realesrgan — AI upscaling

Quick Reference

Situation	Load
Platform specs (YouTube, TikTok, Instagram)	platforms.md
FFmpeg commands by task	commands.md
Quality/compression settings	quality.md
Workflow by use case	workflows.md

Core Capabilities

Task	Method
Convert/compress	FFmpeg (see commands.md)
Generate captions	Whisper → SRT/VTT
Change aspect ratio	Crop, pad, or smart reframe
Clean audio	Normalize, denoise, enhance
Batch operations	Process entire folders in one run

Execution Pattern

1. Clarify target — What platform? What format? File size limit?
2. Check source — ffprobe for codec, resolution, duration, audio
3. Process — FFmpeg for transformation
4. Verify — Confirm output meets specs before delivering
5. Deliver — Provide file to user

Common Requests → Actions

User says	Agent does
"Make this work for TikTok"	Reframe to 9:16, check duration ≤3min, compress
"Add subtitles"	Whisper → SRT → burn-in or deliver separately
"Compress for WhatsApp"	Target <64MB, H.264, AAC
"Extract audio"	-vn -acodec mp3 or -acodec copy
"Make a GIF"	Extract frames, optimize palette, loop
"Split into clips"	Cut at timestamps with -ss and -t

Quality Rules

• Always re-encode audio to AAC for maximum compatibility
• Use -movflags +faststart for web playback
• CRF 23 is good default for H.264 (lower = better, bigger)
• Check before delivering — verify duration, file size, playability

Platform Quick Reference

Platform	Aspect	Max Duration	Max Size
TikTok	9:16	3 min	287MB
Instagram Reels	9:16	90s	250MB
YouTube Shorts	9:16	60s	No limit
YouTube	16:9	12h	256GB
WhatsApp	Any	3 min	64MB

Scope

This skill:

• Processes video files user explicitly provides
• Runs FFmpeg commands on user request
• Does NOT access files without user instruction
• Does NOT upload to external services automatically
