Using -o "%(autonumber)s-%(title)s-[%(id)s].%(ext)s" will write the info to 00001-SQL_Server_GroupBy_vs._MongoDB_MapReduce_Part_2_of_2-[Z616jiybr1E].info.json.
The problem is that we try to drop the extension from the file before adding info.json (foo.mp4 becomes foo.info.json). With the template you used, we identify _MongoDB_MapReduce_Part_2_of_2-[Z616jiybr1E] as the extension, that's why it's removed.
In general you should give an explicit extension in the output template or use .%(ext)s.

Thanks for pointing that out.
