Beatra AI Video Studio

Overview

Beatra AI Video Studio is Beatra's official agent package for short AI video work: text-to-video, image-to-video, first/last-frame interpolation, reference-guided generation, and editing or extending an existing clip. The video is produced on the hosted, paid Beatra service (mcp.beatra.ai).

This catalog entry is a reviewed pointer, not the executable package. It contains no client code and performs no Beatra operation by itself. The package it points to bundles three standard-library Python scripts that make network calls, store a credential, and can replace their own files. Read Install and Security & Safety Notes before activating it.

The archive holds 17 regular files (no symlinks, no executable bits, no binaries), and every file is byte-identical to the source tree at that commit.

When to Use This Skill

• Use when the user explicitly wants a short AI video clip produced on Beatra and accepts that the work is paid and runs on a hosted service.
• Use when a still image should be animated, two frames interpolated, or an existing clip edited or extended by Beatra.
• Do not use for local-only or offline video editing, timeline assembly, or when the user has not agreed to send prompts and media to a third party.

Install (pinned, verified, approved twice)

Step 1: Download and verify into a review directory

Explain that this downloads an external package from cdn.beatra.ai, then ask for approval. Only after approval:

umask 077
review_dir="$(mktemp -d)"
cd "$review_dir" || exit 1
curl -fsSLO "https://cdn.beatra.ai/agent-packages/beatra-ai-video-studio/v1.2.5/beatra-ai-video-studio-skill-1.2.5.zip"
printf '%s  %s\n' \
  '679a3ddc06c7be631ef31f002f918465a26f17a189ffac723f45dfd348e1fc4a' \
  'beatra-ai-video-studio-skill-1.2.5.zip' | shasum -a 256 -c -

Stop if the check does not print OK. The expected digest comes from this catalog entry, not from a file on the same CDN.

Step 2: Inspect before activation

unzip -l beatra-ai-video-studio-skill-1.2.5.zip
unzip -q beatra-ai-video-studio-skill-1.2.5.zip
find beatra-ai-video-studio -type l -print            # expect no output
find beatra-ai-video-studio -type f -perm -111 -print # expect no output
grep -n '"auto_update": True' beatra-ai-video-studio/scripts/mcp_client.py

Optionally confirm byte identity with the public source tree (a second, independent host):

git clone --quiet --filter=blob:none --no-checkout https://github.com/beatra-ai/beatra-skills.git src
git -C src checkout --quiet 95d662f7aeddd6e2aa6da9e14f9c985e3f6b914d -- skills/beatra-ai-video-studio
(cd beatra-ai-video-studio && find . -type f | LC_ALL=C sort | xargs shasum -a 256) > archive.sha
(cd src/skills/beatra-ai-video-studio && find . -type f | LC_ALL=C sort | xargs shasum -a 256) > tree.sha
cmp archive.sha tree.sha && echo IDENTICAL

Report to the user what the review found: SKILL.md, manifest.json, 12 Markdown references, and scripts/authorize.py, scripts/mcp_client.py, scripts/uninstall.py (Python 3.10+, standard library only, no dependency installation, no lifecycle hooks). Summarize the network, credential, local-state, telemetry, and self-update behavior listed under Security & Safety Notes.

Step 3: Copy in and disable self-update before any other command

Ask for a second, separate approval, because this changes agent configuration. Then copy the reviewed tree to the host's skills directory (Claude Code shown; use the equivalent path for other hosts) and immediately turn off silent self-update for that exact path:

dest="$HOME/.claude/skills/beatra-ai-video-studio"
test ! -e "$dest" || { echo "destination exists; stop and ask the user"; exit 1; }
cp -R beatra-ai-video-studio "$dest"
python3 "$dest/scripts/mcp_client.py" update --auto off

The last command must print Automatic Beatra package updates are disabled. It writes only ~/.beatra/updates/<id>/state.json and makes no network request. Run it before authorize.py, verify, tools, upload, or call: in version 1.2.5 self-update is on by default (see below). The setting is keyed to the resolved install path, so repeat it after moving or re-copying the directory.

Step 4: Authorize as its own decision

Authorization opens a browser sign-in and stores a bearer token. Ask first.

python3 "$dest/scripts/authorize.py"

Start a new agent session if the host discovers skills only at startup.

How It Works

1. Read the installed package's SKILL.md and its references; they define the video routes, payload shapes, and review loop.
2. Use free, non-billable discovery first (beatra.models.list, task list) to read current model cards, durations, resolutions, and credit estimates.
3. Show the user a cost card for exactly one paid call: tool, model, duration, resolution, estimate, and which files will be uploaded. Wait for explicit approval. Planning or "make the clip" is not approval.
4. Upload only files the user supplied and approved for this task, then submit once with a stable client_request_id and poll the returned task.
5. Report the delivered artifact and billing.net_charged_credits, review the clip with the user, and ask again before any further paid stage.

Examples

Free connection check (non-billable)

python3 "$HOME/.claude/skills/beatra-ai-video-studio/scripts/mcp_client.py" verify

One approved text-to-video call

After the user approved the cost card for this exact payload:

printf '%s' '{"prompt":"A close product reveal with one slow push-in.","model":"auto","duration":5,"client_request_id":"req-7f3c2a"}' \
  | python3 "$HOME/.claude/skills/beatra-ai-video-studio/scripts/mcp_client.py" call beatra.videos.generate

If the response is lost, retry only with the same client_request_id and identical arguments; never submit a replacement while the task is running.

Update

This entry does not endorse the package's silent self-update. Keep update --auto off in place and do not run update --auto on or a bare update without explicit approval.

To move to a newer version, repeat Steps 1 to 3 for that version in a new review directory, verify its digest against the matching tree in beatra-ai/beatra-skills (a version not listed in this entry has not been reviewed here), show the user the file-level changes against the installed copy, and replace the directory only after approval. update --check reports the available version from beatra.ai without changing files.

Uninstall

dest="$HOME/.claude/skills/beatra-ai-video-studio"
python3 "$dest/scripts/uninstall.py" --dry-run
python3 "$dest/scripts/uninstall.py"

Read the JSON decision. disconnected means this was the last Beatra skill on the device: the token was revoked (when revoked is true) and the files credentials.json, installation.json, host.json, skills.json, and registrations.json under ~/.beatra were removed. keep_connection means another Beatra skill still uses the shared token, which stays. Then, after confirming the path with the user, delete $dest.

uninstall.py does not remove ~/.beatra/updates/. When the decision is disconnected and no other Beatra skill is installed, remove that directory too; otherwise leave it. A token that could not be revoked expires after 15 days idle and can be revoked at once in the Beatra Console under Agents.

Best Practices

• ✅ Keep one approval per paid call, per upload set, and per install step.
• ✅ Start with the shortest duration and lowest resolution the model admits.
• ✅ Report net charged credits from the terminal task, not the estimate.
• ❌ Do not re-enable self-update or install an unreviewed version silently.
• ❌ Do not print, paste, or move the token out of ~/.beatra/credentials.json.
• ❌ Do not retry a paid call with a new request ID after an uncertain response.

Limitations

• Requires a Beatra account, network access, Python 3.10+, and prepaid credits; the sign-up gift usually cannot cover a video generation.
• Short clips only; not a timeline editor. Multi-shot work is delivered as separate clips.
• Generation is asynchronous and can take minutes. Upload size is capped at 100 MB and a model may impose a lower limit.
• Models, prices, schemas, and availability are controlled by Beatra and its upstream model providers and can change; the service is provided as is.
• Outputs are probabilistic, not guaranteed unique or non-infringing, and need human review before publication.

Security & Safety Notes

risk: critical is deliberate.

• Network. Authorization uses api.beatra.ai; every tool call and upload goes to mcp.beatra.ai. With self-update left on, the client also fetches https://beatra.ai/skills/beatra-ai-video-studio/install.json and archives from cdn.beatra.ai.
• Self-update (on by default in 1.2.5). Before verify, tools, upload, or call, the client checks for a newer release at most once every 24 hours and, if one exists, replaces package-owned files without per-update preview or approval. It pins host and path, verifies checksums from Beatra's own discovery document and CDN, and rolls back on failure, but those digests are not independently anchored. This entry therefore requires update --auto off before first use, as in Step 3.
• Uploads and third parties. Prompts and uploaded media are sent to Beatra and forwarded to the third-party model provider executing the task. Beatra is hosted outside mainland China. See the privacy policy.
• Billing. Paid tools consume prepaid credits. Credits for tasks that fail for reasons attributable to Beatra or the upstream model are returned automatically; otherwise purchases are non-refundable, and actual usage can exceed the estimate and leave a negative balance. See the terms.
• Credentials. authorize.py runs an OAuth device flow, opens the browser, and stores one bearer token in ~/.beatra/credentials.json (directory 0700, file 0600). The token never goes into argv, environment variables, or output. It carries full Beatra scope, including wallet:spend, has a sliding 15-day idle lifetime, and is shared by every Beatra skill on the device.
• Local state. ~/.beatra/ also holds installation.json (random installation reference), host.json (agent platform and hostname), skills.json (installed Beatra skill paths), registrations.json, and updates/<id>/state.json plus update backups when updates run.
• Telemetry. The device flow sends the hostname as the device name, the package slug and version, and the detected agent platform (for example claude-code, from environment variables). On first use the client makes a non-billable beatra.installations.register call, and every tool call adds source_package_slug and source_platform. There is no opt-out for these fields.
• Retention. Account data is kept for the life of the account. Task records, artifacts, and billing ledgers are retained after account closure for audit and tax purposes.
• Content rights. Users keep rights in their inputs and receive Beatra's rights in outputs; they must hold rights to uploaded media and must not create deceptive impersonations.
