Your virtual product lands perfectly on a customer’s kitchen counter. Then a caption covers the feature you wanted them to see. That small editing mistake can turn a useful AR demo into a guessing game. With a little planning, you can record a clear WebAR demonstration, shape it into a social video, and add captions that explain the action while leaving the product visible.
Your Demo Game Plan
- Record one product benefit with room for captions.
- Trim the footage before finalizing subtitle timing.
- Check readability and product visibility on a phone.
Choose One Product Question to Answer
A short AR video works best when it answers a specific shopping question. Will this chair fit beside a desk? How does this lamp look on a nightstand? Which planter shape suits a narrow shelf? Choose one question before you record.
WebAR lets people open an augmented reality experience through a supported web browser. Your social video shows that experience in action. The recording itself is a video, so viewers need a separate way to open the interactive demo if you want them to try it.
For a small home goods business, a useful concept might be showing a virtual lamp on a real side table. Start with the lamp already visible. Show how someone places it, moves around it, and checks its proportions. Finish with a clear invitation to try it in their own room.
Write a few short narration sentences before filming. Each sentence should explain what the viewer can see. “Tap to place the lamp” is easier to match with footage than a long introduction about your collection.
Prepare the WebAR Scene for Recording
Open your product experience on the phone you plan to record. Test camera access, model loading, placement, and any controls you intend to show. Do a practice run from the same starting point a customer would use.
Choose a space with steady lighting and visible surface detail. A plain, reflective tabletop may make placement harder in some experiences. A surface with texture gives you a more useful starting point. Clear away objects that distract from the product.
Check the model’s size and appearance before filming. If the experience supports true-scale placement, verify the setup against known product dimensions. Avoid suggesting that viewers can judge exact fit when the model can be freely resized or has not been checked for scale.
Frame the scene with captions in mind. Leave some calm background above or below the product. Keep identifying features, control buttons, and the area where placement happens away from that planned text space.
Record a Short Technical Test
Turn on your phone’s screen recorder and capture a few seconds. Play the file back to confirm that the camera background, virtual model, and interface all appear correctly. Audio capture can vary by device and recording settings, so check that too.
Enable a focus setting that suppresses notifications. Close unrelated tabs and hide personal information that might appear during recording. If live narration makes it harder to control the demo, record your voice separately after trimming.
Capture Product Actions at a Readable Pace
Record vertically when your intended social placement uses a vertical frame. A 9:16 editing canvas is a useful starting point for that format. Keep enough space around the product to adjust the composition later.
Begin with a stable view. Place the product, pause, then move slowly enough for viewers to understand its position in the room. A sudden camera sweep can make a successful placement look unstable.
Let each action finish before starting another. After changing a color, hold the view briefly. After opening a product detail, give the viewer time to see it. These pauses also create space for captions without forcing people to read and track movement at the same time.
Capture a few takes with different framing. One may show the whole object clearly. Another may reveal a useful detail. Save the original recordings so you can revise the edit without repeating the entire demo.
Trim the Demo Around a Clear Beginning and Payoff
Import your recording into an editor that supports a caption track or editable text overlays. Set your canvas before adding text. Cropping a finished horizontal edit into a vertical frame can push both the product and captions out of view.
Remove accidental taps, repeated placement attempts, and unnecessary waiting. Preserve the moments that explain how the experience works. If loading time matters to the demonstration, use a brief transition instead of making the sequence appear instantaneous.
Try a first cut of about 20 to 30 seconds as a creative starting point. Open with the product in the room, show the placement action, then reveal the benefit. Give the closing invitation enough screen time to read without rushing.
Keep decorative text separate from spoken captions. A headline might identify the product, while captions carry the narration. When both compete for the same space, shorten the headline or remove it.
Prepare Existing Subtitles for the Editing Timeline
If you already have a narrated product video with subtitles, reuse that work where it matches the new edit. A subtitle converter can help retrieve available subtitles in a timed format for an editing workflow. Check which formats your editor accepts before downloading.
SRT files contain caption text with start and end times. VTT also supports timed text. A plain text transcript can help with proofreading, but it does not supply the timing your caption track needs.
Import the subtitle file alongside the matching footage. Subtitles from an older edit will not automatically match a shorter social version. Removing an opening segment or rearranging shots can leave every later caption out of sync.
If you are starting with a fresh recording, generate captions from the final narration or enter them manually. Treat automatic transcription as a draft. Check product names, dimensions, prices, and color names against the actual audio and product information.
Match Caption Timing to Speech and Product Actions
Begin each caption when the corresponding words are spoken. End it after viewers have had time to read, while keeping it connected to the speech. Avoid leaving an old instruction visible after the demonstration has moved to another action.
Group words into short, meaningful phrases. “Place the lamp beside your chair” reads naturally as one thought. Breaking that sentence into several flashing fragments makes the viewer work harder.
Use one or two lines when possible. Break lines at a natural phrase boundary. Keep a number with its unit and keep a product name together whenever the available space allows.
If a caption disappears before you can read it comfortably, extend the shot or simplify the narration and record it again. Tiny text is a poor fix for rushed speech. Preserve the spoken meaning when correcting captions.
Include meaningful sounds when they help explain the experience. For example, “[confirmation tone]” may matter if a sound confirms successful placement. Identify a speaker when their identity would otherwise be unclear.
Give Captions Consistent Contrast
A camera background changes constantly. White lettering that looks clear over a dark sofa can disappear when the phone turns toward a bright wall. Give captions a background that stays readable across those changes.
Start with white text on a dark, mostly opaque box. Use a plain font with distinct letter shapes and enough weight to remain clear at phone size. Add padding so the letters do not touch the box edges.
Use sentence case for ordinary speech. Reserve all caps for brief labels when needed. Animated words and frequent color changes can pull attention away from the product demonstration.
Review your longest caption over the brightest and busiest shots. If it becomes difficult to read, adjust the text size, box opacity, or line breaks. Judge the result at normal playback size rather than in an enlarged editing preview.
Place Captions Around the Product’s Movement
Keep captions away from the details that support your sales message. For a lamp, that might be its switch or adjustable head. For a chair, it might be the space between the seat and desk.
The lower center can work when the product sits higher in the frame. A position near the top may suit a low object. Neither location works for every shot, especially when social interface controls overlap the video.
Preview the video in the intended publishing interface. Account names, descriptions, buttons, and other controls can cover text near the edges. Allow generous margins, then inspect the actual preview instead of relying on one fixed margin measurement.
If the product moves through the caption area, adjust the crop or move captions at a natural scene change. Keep the position stable within each shot whenever possible. Constantly shifting text makes reading less predictable.
Export and Review the Video as a Viewer
Choose whether to burn captions into the video or supply a separate caption file where supported. Burned-in captions remain visible as part of the picture. Separate captions can offer viewer controls, but their appearance and availability depend on the publishing platform.
Save a clean master without burned-in text, along with the editable project and subtitle file. This makes later corrections, translations, and alternate crops easier.
Watch the exported file once with sound off. Confirm that the product benefit, demonstrated action, and invitation still make sense. Then watch with sound on to check wording and synchronization.
Review the uploaded preview too. Compression can soften small text, and platform captions may duplicate captions already embedded in the video. Check the available caption settings before publishing.
Leave Viewers Ready to Try the Product
Your final frame should give people one clear next action. Tell them where to open the interactive demo using the destination available for that post. Avoid telling them to tap an element that is only part of the recording.
A useful AR product video lets viewers follow the action, read the narration, and inspect the item without fighting the layout. Plan space for text before recording, finish the trim before refining timing, and review the result on a phone. Those habits make each new demo easier to produce and easier to understand.
