Put it into practice
- Select the product state related to the video.
- Make that region visually dominant.
- Preview it at a small size.
What this looks like
A tutorial about filters uses the filter panel rather than a full browser screenshot.
A detail to keep clear
An exported image is a thumbnail asset, not a video or an interactive preview.
Using MockupX
A social composition is a separate design from the original product screenshot. Use the output frame to establish shape, then test the exported image in the actual destination preview. MockupX does not publish posts or guarantee a platform will display every pixel without cropping.
Check the result
Keep the original screenshot, then review the exported file at the size where people will see it. Check the message, the visible interface and the final crop separately. For a handoff, record the destination and the approved file so another person can distinguish the final version from a draft.
References and further reading
Use the official references for format behavior and current destination requirements. The composition advice above is a practical design approach, not a promise of platform approval.
