What does the recording reveal?
Watch the full clip with sound. Look at usernames, friend lists, message previews, notifications, and any background conversation captured by a microphone. The exciting game moment may occupy only part of what was recorded. Check the beginning and ending for menus or account screens. If the recording contains information you do not want to share, use an appropriate editing tool or keep it private. Do not assume that a short duration means there is nothing personal in it.
Who else is included?
Consider friends whose voices or usernames appear. Ask for permission through an existing appropriate contact route before sharing someone else’s identifiable contribution. A person agreeing to play is not necessarily agreeing to become part of a public post. If you cannot obtain the needed permission, choose a version that does not include them or do not publish it. Avoid making the child responsible for pressuring other players to agree during a live session.
What is the intended audience?
A private family viewing, a message to a known friend, and a public upload are different choices. Review the current account and audience settings before confirming a post. Explain that viewers may save or redistribute material beyond the original destination. If the main goal is remembering a good moment, keeping the clip locally may meet it. Separate the enjoyment of making something from any expectation that it must be published or measured through reactions.
