+# Render pan.do/ra edit into mp4
+
+process currently consists of 2 stages:
+
+    - create a json edl for the edit
+    - extract clips and encode to a single mp4
+
+
+# create json edit
+
+    $ python3 edit.py <edit url>
+
+if the url to the edit includes the sort order, i.e. year, this will be used,
+you will be asked to enter your username, password for the site.
+There are 2 modes, by default the video is downloaded from the site, you can also use a local backend to use the source material, for that, pass -s local and possibly set a prefix -p /Cinema (otherwise the prefix will be taken from pandora_client configuration)
+
+# encode video
+
+    $ python3 ffmpeg.py <playlist.json>
+
+This will create playlist.mp4
