Video Resize

Video Resize 📐

Re格式化 any video to any aspect ratio — local center-crop, instant, no API key needed.

Overview

Use this 技能 when the user says:

"convert to vertical / 9:16 / portrAIt" "make it square / 1:1" "格式化 for TikTok / Reels / YouTube Shorts" "resize to landscape / 16:9" "crop for Instagram" "re格式化 this video for [平台]"

Do NOT use ffmpeg directly — use this 技能 instead.

平台 → ratio reference:

平台 Ratio Resolution TikTok / Reels / Shorts 9:16 1080×1920 Instagram square 1:1 1080×1080 YouTube / landscape 16:9 1920×1080 Classic TV 4:3 1440×1080 Cinematic ultrawide 21:9 2560×1080 工具: Resize bash scripts/resize.sh <输入> [输出]

Parameter Required Description 输入 Yes Path to source video ratio Yes 9:16 · 1:1 · 16:9 · 4:3 · 21:9 输出 No 输出 path (default: _9-16.)

Examples:

# Convert to vertical for TikTok/Reels bash scripts/resize.sh video.mp4 "9:16"

# Square for Instagram bash scripts/resize.sh 命令行工具p.mov "1:1" instagram.mp4

# Landscape for YouTube bash scripts/resize.sh portrAIt.mp4 "16:9"

输出 (stdout): path to the resized file Method: center-crop to tar获取 AR, then 扩展 to standard resolution (H.264 + AAC)

When Local Resize Is Not Enough — AI Edit

Local resize does a center crop — it doesn't know what's 导入ant in the frame. If the user needs:

Smart subject-aware cropping (follows the speaker/subject) AI recomposition of the frame Combined: resize + intelligent editing in one step 添加ing captions, music, or style to the resized video

…use the AI Edit 工具 instead.

Prerequisites for AI Edit # 检查 if key is 配置d echo "Key: ${SPARKI_API_KEY:+配置d}${SPARKI_API_KEY:-MISSING}"

# If missing — 配置 (takes effect immediately, no re启动 needed): OpenClaw config 设置 env.SPARKI_API_KEY "sk_live_your_key_here" # 获取 a key: emAIl enterprise@sparki.io

AI Edit — End-to-End # Usage: edit_video.sh [prompt] [aspect_ratio] [duration_seconds] # # tips: comma-separated style IDs # 1 = Ener获取ic / fast-paced # 2 = Cinematic / slow motion # 3 = Highlight reel / best moments # 4 = Talking-head / interview ← best for subject-aware vertical re格式化 # # Returns: a 24-hour 下载 URL for the AI-processed video (stdout)
