The Ultimate Guide to the A/V (Two-Column) Script Format for Commercials
How to write an A/V script in two-column format for commercials, promos, and corporate video. What goes in each column and when to use it instead of screenplay format.
Not every script is a screenplay. If you're writing a commercial, a promo, an explainer, or corporate video, the standard screenplay format is the wrong tool — you want the A/V (audio-video) two-column format, where picture and sound sit side by side. Here's how it works.
Why two columns?
Short-form video is built on tight sync between what's seen and what's heard. A voiceover line has to land on a specific shot; a graphic has to appear on a specific word. Two columns let you line them up literally, row by row — which a single-column screenplay can't do cleanly.
The layout
| VIDEO | AUDIO |
|---|---|
| Wide shot: a runner laces up at dawn, empty street. | MUSIC: soft piano builds. |
| Close on worn shoes hitting pavement. | VO: "Every season starts with a single step." |
| Logo animates onto screen. | VO: "Northline. Made for the distance." SFX: gentle whoosh. |
- Left (VIDEO) — everything on screen: shots, on-screen text, graphics, action.
- Right (AUDIO) — everything heard: voiceover (VO), dialogue, music, and sound effects (SFX), aligned to its visual.
What goes where
Video column:
- Shot descriptions and framing
- On-screen text and lower thirds
- Graphics, animation, and transitions
- Product beauty shots
Audio column:
- VO — narration
- Dialogue — on-camera speech
- MUSIC — cues and mood
- SFX — sound effects
Keep each row's video and audio aligned so anyone reading knows exactly what plays over what.
When to use A/V vs. screenplay format
| Use A/V two-column for… | Use screenplay format for… |
|---|---|
| Commercials & ads | Feature films |
| Corporate & explainer video | TV episodes |
| Promos & trailers | Short narrative films |
| Training & how-to video | Anything story-driven |
The rule of thumb: narrative → screenplay format; message-driven short-form → A/V.
Keep the columns aligned
The practical challenge of A/V scripts is keeping the two columns synced as you edit — add a line on one side and the alignment can drift. A tool that supports the two-column format keeps video and audio locked together row by row. Scriptease handles A/V alongside standard screenplay format, so you can write both kinds of project in one place.
