The most common recording problem is not video encoding. It is identifying the correct creator. A nickname is convenient for people but is not a durable database key.
Why the numeric MICO ID is preferred
A numeric MICO ID remains stable when the creator changes their display name, adds emoji or changes capitalization. MicoRec stores this ID in the watchlist and prints it in recording captions so you can verify the source later.
If you send a nickname, MicoRec searches the public directory. A missing or duplicated nickname cannot be accepted safely because the bot might choose the wrong person. Sending the numeric ID avoids that ambiguity.
Copy an official share link
Open the public MICO live, use MICO's share action and copy its official HTTPS link. MicoRec accepts official public MICO live-share links and rejects unrelated URLs.
You can paste the share link after /rec or /watch. The URL is used for identity resolution; MicoRec does not ask you to sign in through a third-party page.
What if an ID is not found?
An ID may be valid but absent from the current public live directory. If the creator is live, use the official share link. If they are offline, try /watch again during the next public live.
Can I use an @username?
MICO display names are not equivalent to unique Telegram usernames. Use the number displayed by MICO whenever possible.
