How do I change my video thumbnail?

1. Open the video and select Design in the left menu.
2. Scroll to Branding and find Thumbnail.
3. Select Add Thumbnail, or Change if the video already has one.
4. In Choose image, pick a frame on the Suggested tab, or open Library to upload an image or pick one you used before.
5. In the Player section, check that Use Looping Preview is off. When it is on, viewers see a short moving loop instead of the thumbnail.
6. Test: open the share link in a private browser window. Expected result: your thumbnail shows before you press play.

• Before playback, in the player, on the share link and in embeds (when Use Looping Preview is off).
• In your video library in Mindstamp.
• As the preview image when the link is shared in chat, email and social apps. Sites cache this image, so an old image can stay for a while after you change it.

• Match the shape of the video, such as 16:9 for most videos or 9:16 for vertical video.
• Use an image at least 1600 pixels wide so it stays sharp on large screens.
• Use one clear subject with strong contrast. Small text becomes hard to read in a message preview.
• Leave space in the corners. The play button and your logo can sit on top of the image.

Each video keeps its own thumbnail. Apply to videos… and design resets do not change it. Suggested frames are available for videos uploaded to Mindstamp.

• Check that Use Looping Preview is off.
• Reload the page in a private window to skip your browser cache.
• For social and chat previews, the other site may keep the old image until its own cache expires.
