Did you manage to solve your problem?
I tested your $SQL statement on a database and because you are using DESC it got the last 10 rows:
$sql = 'SELECT * FROM videos ORDER BY id DESC LIMIT 0, 10';
// id = 3300 .. 3291
$sql = 'SELECT * FROM videos ORDER BY id DESC LIMIT 4, 10';
// id = 3296 .. 3287
If you want records 5…14 you must use ASC
$sql = 'SELECT * FROM videos ORDER BY id ASC LIMIT 4, 10'; // 3296 .. 3287
// id = 5 .. 14
Special Note:
ASC is the default and therefore no need to declare.
