+# encoding profile file #
+#########################
+#
+# Note: by default, this file is installed to /etc/mpv/encoding-profiles.conf
+# (or a different location, depending on --prefix). mpv will load it by
+# default on program start. If ~/.mpv/encoding-profiles.conf exists, this file
+# will be loaded instead.
+#
+# Then, list all profiles by
+#   mpv --profile=help | grep enc-
+#
+# The following kinds of encoding profiles exist:
+#   enc-a-*:  initialize an audio codec including good defaults
+#   enc-v-*:  initialize a video codec including good defaults
+#   enc-f-*:  initialize a file format including good defaults, including
+#             selecting and initializing a good audio and video codec
+#   enc-to-*: load known good settings for a target device; this typically
+#             includes selecting an enc-f-* profile, then adjusting some
+#             settings like frame rate, resolution and codec parameters
+#
+# AFTER including a profile of these, you can of course still change
+# options, or even switch to another codec.
+#
+# You can view the exact options a profile sets by
+#   mpv --show-profile=enc-to-hp-slate-7
+#
+# Examples:
+#   mpv --profile=enc-to-dvdpal --o=outfile.mpg infile.mkv
+#   mpv --profile=enc-f-avi --vf=fps=30 --o=outfile.avi infile.mkv
+#   mpv --profile=enc-v-mpeg4 --ovcopts-add=qscale=7 --profile=enc-a-mp3 --oacopts-add=b=320k --o=outfile.avi infile.mkv
