I'll remove it in a future plugin release. Could I manage to make a GOP Size of half the framerate through other means then? Header Insertion Spacing perhaps?\r\n\r\n*CABAC* is actually recommended for most streams, since you can usually pack ~5% more bits into the stream on average.  So the extra 200-300 kbit/s per second would actually end up being nearly the same exact bitrate as you would need for near-identical software encoding quality.\r\n\r\nI don't know about other parameters that need to be exposed yet. If there are some, I will open up an issue for it on the AMF issue tracker.\r\n\r\n@Benman2785 Ich habe deine Antwort auf die extrem verzögerte E-Mail Antwort von mir entfernt. Tut mir Leid wegen der miesen Reaktion, ich war an dem Tag sehr genervt davon dass du wiederholt experimentelle Parameter genutzt hast ohne aktuell zu wissen ob diese wirklich funktionieren - und dann auch noch andere dazu aufrufen wolltest diese zu verwenden."}}
