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.
- 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.mdfile 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.
