Videos in a gallery are watched differently
A film in a cinema or at home has a captive viewer who chose to sit down. A film in a gallery has a visitor who is on their feet, perhaps with others, perhaps with a child, and who may watch for thirty seconds before moving on. Good exhibit video accepts this. It is short, clear from the first seconds and still makes sense if someone joins in the middle.
Video is also not always the right answer. If the content is a fact that a sentence conveys, or a process that a diagram shows well, a film may be an expensive way to say it. Video earns its place when people, voices, movement or atmosphere are what the visitor needs: a craftsperson at work, a place that cannot be visited, a person telling their own story.
Decide the single point
Start with one sentence stating what the visitor should understand or feel afterward. Everything in the script should serve that sentence. Material that does not is a candidate for cutting, however good it is. The shorter the film, the stricter this has to be.
Length and structure
There is no universal right length, and published figures about visitor attention vary and should be treated cautiously. As a working rule, many exhibit teams aim for pieces of a minute or two for a general audience, and keep longer films for dedicated seating areas where people expect to sit. The honest approach is to decide the length from the content, then test with visitors, a step described in the sections on prototype testing and dwell time.
A few structural habits help:
- Open with the strongest image or idea, not with credits or a title card.
- Make each section self-contained, so a visitor who arrives halfway still gets something.
- Design the loop. If the film repeats, the end should flow naturally into the beginning, or a brief clear pause should signal a restart.
- Consider a short film or a set of chapters instead of one long one, letting visitors choose.
- Put credits somewhere else, such as a label or the end of a longer cut, if they would otherwise interrupt the loop.
Scripting
Write for the ear. Read the script aloud and listen for sentences that run too long or phrases that trip the tongue. Use plain language, avoid jargon and keep sentences short. Match words and pictures: when the narration names something, the visitor should see it at about that moment, and the narration should not describe what is obviously on screen.
A two-column script works well, with the visual in one column and the sound (narration, speech, music) in the other. Have a subject expert check facts at script stage, and a second person unfamiliar with the topic confirm that it is understandable. Changes during editing cost far more than changes on paper.
If the film features people talking, the process resembles that of oral histories, including preparation and consent. The rules for filming visitors themselves are covered under visitor consent.
Pacing
Give each image enough time to be read. Archive photographs, documents and maps often need longer on screen than a filmmaker’s instinct suggests, especially if the text is small. Vary the rhythm so the film does not feel monotonous, but avoid rapid cutting for its own sake. Let important moments breathe. Music can set tone, but it should not compete with speech and should not run so loudly that it spills into neighboring spaces.
Filming practicalities
A small team can do a lot with modest equipment if the basics are right:
- Sound first. Poor audio spoils a film faster than modest picture quality. Use an external microphone placed close to the speaker, and monitor with headphones. Record in a quiet room and record a short stretch of room tone to help the edit.
- Stable shots. Use a tripod or other support for most footage. Handheld movement should be deliberate.
- Good light. Soft, even light on faces, and windows behind the subject avoided unless handled.
- Frame for the screen. Consider the display’s shape, whether landscape or portrait, and where the film will sit. Leave room for captions at the bottom.
- Shoot extra pictures that cover the narration, such as hands, details and wide views, known as cutaways.
- Get releases and permissions from everyone who appears or whose work is shown, and clear music, archive footage and photographs, as set out in image permissions.
Accessibility
Many gallery videos play without sound, because audio is turned down, the room is noisy or visitors do not want to disturb others. Plan for this from the beginning. Captions should be built in, not added in a rush, as covered in writing captions and transcripts. For deaf visitors, sign language options may be worthwhile on key films. Visitors who are blind or have low vision benefit from audio description, which is easier to include if the narration is written to name the important visuals. Avoid flashing images, and where sudden loud sound is possible, consider a more even level.
Audio output is also an exhibit design problem. Sound from one film can intrude on the next exhibit, so directional speakers, headphones or captions-only playback may be worth considering, with attention to sound bleed.
Editing, export and playback
Edit with the final screen in mind, and check text legibility at gallery distance. Export in a format the playback hardware handles comfortably. The best approach is to test on the actual media player for a full day of repeated looping, because an export that plays on a laptop may stutter on a modest device. Make sure the film restarts cleanly after a power cut. Keep the project files, the script, a caption file and a clean version without text, so edits and translations can be made later.
Review and upkeep
After opening, watch how visitors respond. Do they stop, watch and leave, or walk by? Informal observation often shows whether a film is too long or too hard to hear. Plan to revisit it. Facts change and so do audiences, and a film that cannot be updated cheaply may need a modular structure from the beginning.
