# Glossary

These are the terms you'll meet while you make a video with the promo video skill.

**Alignment**
: How closely a voice take matches the script, shown as a percentage. Claude uses it to time the pictures to the voice. Above 90% is normal. Below 80% usually means the take doesn't match the current script.

**Approval point**
: One of two moments when Claude stops and waits for your decision: after the storyboard, and after the final videos. See [How a promo video gets made](how-it-works.md#two-approval-points).

**Audio tag**
: A direction for the voice, written in square brackets in the script, such as `[Warm, assured]` or `[short pause]`. Audio tags aren't spoken and don't appear in captions.

**Brief**
: The `brief.md` file in the project. It records your answers, where each line of the script comes from, and the project's status.

**Captions**
: Words that appear on screen as the voice speaks them. They're part of the video picture and can't be turned off by the viewer.

**Check report**
: The report Claude makes after each render. It lists the video's length, loudness, alignment, and any warnings.

**Connector**
: A tool connected to your Claude session that lets Claude use another service, such as ElevenLabs, on your behalf.

**Cue**
: A word in the script that triggers something on screen, such as a label appearing when the voice says "inbox."

**Custom scene**
: A scene built for your product, such as a recreation of one of your real screens. Compare with *library scene*.

**Cut**
: One version of the video, with its own length and shape, such as the 30-second cut or the 15-second vertical cut.

**Draft**
: A quick, lower-quality version of a cut, made for review before the real voice is recorded.

**ElevenLabs**
: The AI voice service that produces the voiceover. The skill uses its Eleven v4 model.

**Guide voice**
: A robotic placeholder voice that Claude uses for drafts on a Mac, so you can hear the timing before you record the real voice.

**Hero**
: The main, longest cut, usually 60–90 seconds.

**Library scene**
: A ready-made scene type, such as a headline, feature list, or logo. Library scenes connect the custom scenes.

**Loudness**
: How loud the voice sounds overall, measured in LUFS. Claude sets every take to a standard loudness for web and social video.

**Remotion**
: The video tool the skill uses to turn the project into MP4 files.

**Render**
: To turn the project into a finished video file.

**Scene**
: A short animated shot in the video, tied to one or more lines of the script.

**Script**
: The words the voice reads, including audio tags. Each cut has its own script.

**Seed**
: A number in ElevenLabs that helps a regenerated take sound like an earlier one.

**Skill**
: A set of instructions and tools that Claude Code loads for a specific kind of task. This one makes promo videos.

**Storyboard**
: An image with one still frame for each line of the script, so you can check the whole video at a glance.

**Take**
: One recording of a cut's script by the voice. You usually generate three or four takes and choose one.

**Vertical cut**
: A cut shaped for phones, 1080 × 1920 pixels.
