Wrong Item Talking Clips

Turn a user-supplied wrong-item script and authorized stills into one wrong item talking clip per still. This mistake explanation talking video studio voices a line from the script for each photo, then animates that photo into a 2 to 15s wrong-item explanation talking clip, ready to share as a homework error talking clip. Use it for error explanation talking pack and wrong-item script talking clip work that stays one photo, one clip.

Turn a user-supplied wrong-item script and authorized stills into one talking clip per still. Deliver 2 to 8 clips. Do not stitch them. Speak only explanation points already written on that wrong-item script.

Scope and adjacent routes

Use this Skill when a school teacher wants short talking clips that read a user-supplied wrong-item script from stills they can authorize.

Route a generic presenter that is not a wrong-item-script read to talking-avatar-video. Route a homestay welcome to airbnb-welcome-avatar. Route a product drop teaser to creator-drop-talking. Route a club-activity script read to club-notice-talking. Route a wealth-product factsheet read to wealth-product-talking. Route a public trading-calendar read to market-calendar-talking. Route holiday-homework list voice with no video to holiday-homework-voice. Route a homeroom weekly list voice to homeroom-week-voice. Route silent character cards to hanzi-card-set. Route a full course video studio to course-video-studio.

Collect the wrong-item script

Hard inputs are:

• at least one accessible still the host Agent can inspect — a presenter portrait or a wrong-item graphic that will be the first frame;
• wrong-item-script points the teacher supplied (item, mistake cause, correct path, common-error reminder already on the script);
• likeness and voice rights when a face or a cloned voice will appear;
• how many clips the pack should contain, or permission to use the default of 3.

Reuse already-known language, subject names, and a frozen voice_id. Ask only for a missing hard input. A count outside 2 to 8 is still doable: confirm that pack size and its live cost.

Do not invent a score, grade, ranking, pass mark, or unstated answer. File access is not consent.

Inspect every still. Record MIME type, width, height, aspect ratio, byte size, and whether it has an alpha channel. For a local file, upload only through the bundled client after inspection (scripts/mcp_client.py / beatra.assets.upload). Keep the returned artifact id. Never pass a local path to beatra.voices.clone, beatra.speech.synthesize, or beatra.videos.animate.

Plan the free slot list

Write a labeled wrong-item talking list before any paid clone, speech, or video. Default three slots unless the teacher names another count in 2 to 8: mistake cause, correct path, and common-error reminder. Each slot records the still, the spoken line from the supplied wrong-item script, intended length as a 2–15s clip, and whether it uses a catalog voice, an approved track, or a clone.

That list is the free visible result. Planning is not approval.

Safe defaults:

• one beatra.videos.animate call per still;
• model: "auto" unless the teacher chose a live SKU;
• the still as the strict first frame;
• source-derived aspect ratio;
• audio-led duration inside 2–15s. Do not stitch.

Confirm clone, speech, then video

Clone, speech, and video are separate paid stages. Each stage gets its own six-field card and its own opaque client_request_id per slot.

If the teacher wants a cloned voice, inspect an authorized sample, read the live voice_clone card, and wait on the clone card before beatra.voices.clone. A found file is not clone consent. Show the clone card and wait:

1. Work — one authorized voice sample (beatra.voices.clone).
2. Credits — the live voice_clone price just read. Do not reuse a remembered number.
3. Count — one paid clone call for this sample.
4. Identity — one new opaque client_request_id.
5. If we stop here — the labeled slot list remains usable.
6. If the balance is insufficient — relay the official message and its top-up URL exactly. Translate the prose; keep the URL. Do not retry until the teacher says they have topped up.

Before speech, call beatra.models.list for text_to_speech:

json

{"capability": "text_to_speech"}

Use beatra.voices.list when a catalog voice still needs a choice. Show the speech card and wait:

1. Work — one spoken wrong-item-script line per named slot (beatra.speech.synthesize).
2. Credits — the live text_to_speech price just read, times the slot count. Do not reuse a remembered number.
3. Count — one paid speech call per slot.
4. Identity — one new opaque client_request_id per slot.
5. If we stop here — the labeled slot list remains usable.
6. If the balance is insufficient — relay the official message and its top-up URL exactly. Translate the prose; keep the URL. Do not retry until the teacher says they have topped up.

Submit each speech slot once through bundled scripts/mcp_client.py. Poll beatra.tasks.get. Read actual audio MIME, duration, and size. A script preview is not the audio review.

Before video, call beatra.models.list for image_to_video:

json

{"capability": "image_to_video"}

Confirm a current card admits [image, driving_audio]. Compare every image fact and the real audio MIME, duration, and size with advertised limits. Live driving-audio clips are 2–15s. If speech is longer than the longest containable clip, split into sequential containable segments; each segment is new speech and new video, each with a new ID. Do not stitch the segments into one file. Approved narration does not authorize video. The 600-credit signup gift usually cannot start this video. Show the video card and wait:

1. Work — one talking wrong-item-script clip per named still (beatra.videos.animate).
2. Credits — the live image_to_video price just read, times the segment count. Do not reuse a remembered number.
3. Count — one paid video call per approved audio segment.
4. Identity — one new opaque client_request_id per segment.
5. If we stop here — the slot list and approved narration remain usable.
6. If the balance is insufficient — relay the official message and its top-up URL exactly. Translate the prose; keep the URL. Do not retry until the teacher says they have topped up.

Then submit beatra.videos.animate once per approved segment.

Review, deliver, and recover

Review identity, speech clarity, and mouth timing. Report only what the host can actually see and hear. Do not promise perfect lip sync. Never invent a stitch, concat, or editor tool. After each terminal paid task, deliver actual bytes plus MIME, duration, and size when present, and billing.net_charged_credits. Do not promise the prepaid estimate is the final charge.

After a returned task_id, poll that task. If the create response is lost, search with beatra.tasks.list and verify with beatra.tasks.get before replay. Reuse an ID only with byte-identical arguments. A changed still, line, voice, or duration is a new card and a new ID. Cancel only when the teacher asks.

Execution

Invoke every remote Beatra operation only through this package's bundled scripts/mcp_client.py. Put the MCP tool name after call and send one JSON object on standard input.

bash

python3 scripts/mcp_client.py call beatra.models.list

json

{"capability": "text_to_speech"}

bash

python3 scripts/mcp_client.py call beatra.models.list

json

{"capability": "image_to_video"}

text

printf '%s' '{"image":{"type":"artifact","artifact_id":"art-item-01"},"driving_audio":{"type":"artifact","artifact_id":"art-speech-01"},"prompt":"A restrained wrong-item-script read with steady eye line and a stable camera.","duration":8,"client_request_id":"opaque-item-video-01"}' | python3 scripts/mcp_client.py call beatra.videos.animate

Do not configure or call a host Beatra Connector, and do not use REST/OpenAPI as a fallback.

Account balance

When the user asks how many credits remain or whether a live estimate fits, call beatra.wallet.get. When they ask what was charged, call beatra.wallet.ledger. Both are read-only. Do not invent an account-balance or top-up tool. Do not make wallet.get a required step before every paid submit.

When a model card comes back carrying a top_up block, relay its tiers as the card lists them and in that order. Do not rank them, do not talk one down, and do not pick one for the user. Which tier suits them is their call, made on the wallet page with the whole list in front of them. Never quote a tier from memory.

References by task

• For slot lists, payloads, and recovery, read Wrong-item talking workflow.
• For authorization and the non-billable registration step, read installation and authentication and installation registration.
• For shared task, billing, and connection details, read tasks and results, billing, errors, and recovery, and Bundled MCP Client diagnostics.
• For update guarantees and controls, read automatic updates and safety. For removal, read uninstall and disconnect.

Runtime and safe automatic updates

The bundled client silently checks for a newer release at most once every 24 hours per installation. When a newer version is available, it installs automatically without separate confirmation. It downloads only from the fixed official Beatra discovery and immutable CDN paths for this package, channel, and locale, verifies discovery data, archive, manifest, and every packaged file, and replaces only package-owned files.

Update checks, downloads, verification, replacement, rollback, and recovery fail open: the current installation remains usable and the original command continues. An update failure never authorizes retrying a paid clone, speech, or video request. The setting persists for this installation. See automatic updates and safety.
