How to Add Inline Photo and Video Reveals That Expand Fullscreen in a Chat Story

In both mystery chat stories and product demo videos, showing a picture or video clip at the exact moment a character says "Look at this" is ten times more effective than describing it in text. Glance Studio lets you attach photos or videos inside the conversation and transition them into fullscreen playback so small details stay crystal clear.

When to keep media inline vs expanding to fullscreen

Inside a 3D iPhone chat bubble, a small thumbnail is enough for a simple visual reaction, but tiny UI buttons in an app demo or a subtle background detail in a horror clue will be too small to read unless the attachment expands.

How to stage an inline media reveal in 4 steps

Release builds of Glance Studio support up to 30 media changes across a project, giving you plenty of room to coordinate attachments and background shifts.

  1. Prepare a clean photo or short vertical screen recording that you created or have permission to publish, free of personal notifications.
  2. In your Glance Studio script, write a short setup line right before the attachment (such as "Here is what the camera caught" or "Tap this button right here").
  3. Attach the photo or video message to the character's reply and enable fullscreen expansion if viewers need to inspect fine detail.
  4. Add one concise reaction message after the fullscreen clip returns to the chat, then export and inspect the 1080x1920 MP4.

Keep product demonstrations truthful to the shipping build

When you use a chat story to demonstrate your own software or shop item, make sure the attached screen recording shows real, shipping behavior and that viewers understand the surrounding dialogue is a scripted walkthrough rather than a real customer transcript.

How many media attachments or changes can I include in one project?

Glance Studio release builds support up to 30 media changes and up to 30 messages per project.

Does an exported Glance Studio MP4 have a transparent background for overlaying in other apps?

No. Standard MP4 exports (HEVC or H.264) are flattened 1080x1920 videos. Set your desired background media directly inside Glance Studio before exporting.

Can I attach both still photos and video clips inside the conversation?

Yes. You can attach photos or video clips inside chat messages as well as setting photo or video backgrounds behind the stage.
