-converting all audiostreams in all files with given file extension in your current working directory and all subdirectories to opus.
+This script converts all audiostreams in all files with given file extension in your current working directory and all subdirectories to opus.
 The Script will choose an automatic bitrate for every audiostream dependent on the number of channels and the original bitrate.
 See https://wiki.xiph.org/Opus_Recommended_Settings for more information about this.

+This Script is unfinished and not ready for usage.

+This script converts all videostreams in all files with given file extension in your current working directory and all subdirectories to vp9.
+The standard settings are in my opinion good for personal storage of movies. Feel free to change them or suggest changes.
+
+If used on containers with subtitles or audiostreams, this skript will only convert the videostream and copy the other streams in a Matroska container.
