Constraints

Prerequisites: Meta account; Muse free tier available; Instagram linked to the same Meta Account Center for automatic connector linking. Access via browser at muse.ai or mobile app. Recommended: turn off the AI improvement switch in Data Controls before first use to prevent commercial data from being used for model training.

What they did

On 2026-10-29, the author logged into Muse with their Meta account and sent three Japanese prompts in one chat: generate a 16:9 promo image (~40s), convert it to a ~6-second 9:16 vertical video (1–2 min), and request publishing as an Instagram Reel (~30s after manual confirmation). Before publishing, Muse showed a confirmation card; the author verified the account name and caption, tapped 「許可する」, and later confirmed the video appeared in their Instagram Reel list.

How it went

Author reported: image ~40s, video 1–2 min, publishing ~30s after confirmation; one cycle of image + video + post consumed 2% of the free tier (author_report).

Worth knowing

1. Muse may auto-insert sample dates and URLs into images; these must be manually verified to avoid publishing incorrect information. 2. Video conversion re-crops horizontal images to vertical; check that important elements are not cut off. 3. Publishing creates a real public post—even practice runs go live. 4. Not verified in this single run: actual Reel playback and caption display, quota consumption for consecutive batches, or behavior on mobile app. 5. The LINE contact at the end is an optional setup-guide CTA from the author, not required for execution.

Steps

  1. Check three settings

    Open Muse, tap bottom-left 「＝」→「設定」. Confirm: ① Data Controls: turn off 「AIモデルの改善にご協力ください」 (tap switch → confirm with 「オフにする」); ② Access Permissions: keep default 「一部のアクションの前のみ確認」; ③ Connectors: verify Instagram shows as 「リンク済み」. If not auto-linked, add Instagram to the same Meta Account Center first.

  2. Send first prompt to generate promo image

    Send the prompt in Muse chat to request a 16:9 promo image. Skip the first sentence if you have already set your name. Image generates in about 40 seconds. After generation, carefully check if any sample dates or URLs were auto-inserted into the image; fix discrepancies before proceeding.

    名前の入力は後にします。まず試験として、新商品の発表を知らせる販促用の画像を作ってください。明るいオフィスの机の上に、白いコーヒーカップとノートパソコンがあり、16対9の横長で、人物は写さないでください。

  3. Send second prompt to convert image to 6-second vertical video

    Continue in the same chat with the second prompt to convert the image to a 9:16 vertical video. Takes about 1–2 minutes. After completion, play to verify: composition may be re-cropped from horizontal to vertical, check if important elements are cut off, and verify if sample text from the image persists. Only proceed to publishing after confirmation. Completion status appears in the right-side 「アクティビティ」 panel.

    この画像を使って、9対16の縦長で6秒ぐらいの動画を作ってください。画面の下半分に「試験用の動画です」という文字を入れてください。

  4. Send third prompt and manually confirm Reel publishing

    Send the third prompt requesting the video be posted as an Instagram Reel. Muse displays a confirmation card showing target account, caption, and video thumbnail. Verify account name and caption match your intent, then tap 「許可する」; tap 「許可しない」 if anything is wrong. Publishing completes in about 30 seconds after approval. Note: this will create a real public post even if intended as practice.

    さきほど作った縦長の6秒の動画を、私のInstagramにリールとして投稿してください。キャプションは「試験投稿です」の一言だけにしてください。
