+(see :doc:`streaming`). You can also use x264 to produce the recording to disk
+instead of Quick Sync, using the --x264-record-video flag. If you wish to have
+separate flags for streaming and storing to disk (e.g., to keep a digital intermediate
+on disk), and have Nageru 2.1.0 or newer, you can use the --separate-x264-disk-encode flag (and associated
+--x264-separate-disk-bitrate flags etc.). Otherwise, the same stream will go
