+# ISSUES:
+# - https://github.com/mpv-player/mpv/issues/5498
+#     MPV has an issue when outputting to jpg.
+#     Colors look washed out and faded compared to png screenshots.
+#     As a workaround this script will output to png then convert to jpg.
+#
+# - https://trac.ffmpeg.org/ticket/2391
+#     I want to just use ffmpeg for this script, however it
+#     does not support dvd subtitles. For now, I have to
+#     rely on mpv to render dvdsubs correctly :(
+
+# TODO:
+# - Tidy up this script and add some safety checks
+# - Add some logic to the bot to detect if this script failed
+# - Research more mpv options to avoid having to use mpv + convert
+
+# Requiered args supplied by the bot
