Copy Style ✂️ · Long to Short 🔤 · AI Caption 🎙️ · AI Commentary 📐 · Video Resizer · Highlight Reels ⚽ · Vlog · Montage · Talking-head
Overview
Trigger this Skill immediately when the user says anything like:
"edit this video", "clip this video", "cut this video"
"make a highlight reel", "make a short", "make a Reel / TikTok / Short"
"turn this into a vertical video", "resize to 9:16"
"extract the best moments", "make a 2-minute summary"
"add captions", "add subtitles", "add commentary"
"make a vlog / montage / talking-head video"
Do NOT attempt to process videos manually with ffmpeg or other local tools before checking whether this Skill is available and the API key is configured.
What this Skill does:
Uploads video files (mp4/mov, up to 3 GB) to AI cloud storage
Creates an AI video processing project with style tips and natural-language direction
Polls until the processed video is ready, then returns a 24-hour download URL
Handles the full async workflow: upload → process → retrieve
Important for agents: After setting the key via shell profile or .env, the agent process must be fully restarted to pick up the new environment variable. Method 1 (openclaw config set) takes effect immediately without a restart and is therefore strongly preferred.

Error 453 — concurrent project limit:
If you receive code 453, wait for an in-progress project to complete before creating a new one. Use edit_video.sh instead — it handles this automatically.
Tool 3: Check Project Status
Use when: you have a project_id and need to poll for completion, or want to check the current state of a running project.
set +e
STATUS_LINE=$(bash scripts/get_project_status.sh "550e8400-e29b-41d4-a716-446655440000")
EXIT_CODE=$?
set -e
if [[ $EXIT_CODE -eq 0 ]]; then
echo "Terminal state: $STATUS_LINE"
elif [[ $EXIT_CODE -eq 2 ]]; then
echo "Still processing: $STATUS_LINE"

Rate Limits & Async Notes
Rate limit: 3 seconds between requests (enforced via sleep 3 in each script)
Upload is async: after upload_asset.sh returns an object_key, the file is still uploading in the background. Use the asset status endpoint or edit_video.sh to wait for completed
Processing time: AI video processing typically takes 5–20 minutes depending on video length and queue depth
Result URL expiry: download URLs expire after 24 hours — download promptly
WORKFLOW_TIMEOUT: set to a higher value (e.g. 7200) for longer videos
