Error in video_update_6405

function video_update_6405() {
  $ret = array();

  db_drop_table($ret, 'video_rendering}');
  db_drop_table($ret, 'video_files}');

I don't think the '}' should be in the table name?

Also get error unknown table 'video_files' query: DROP TABLE video_files

Perhaps the update should be:

function video_update_6405() {
  $ret = array();

  if (db_table_exists('video_rendering')) db_drop_table($ret, 'video_rendering');
  if (db_table_exists('video_files')) db_drop_table($ret, 'video_files');
