 ====== HandBrake and x264 ======

+I'm trying to document a number of changes in encoding which I won't go into here, but I started with the base idea of I want to be able to duplicate HandBrake (1.0.2) and x264's (20160920, same as HandBrake) encoding settings.
 To get the x264 encoding settings, I use [[mediainfo]], and process it with a script I call [[x264_info]].
 There's a difference between HandBrake's and x264's default settings. Based on the x264 defaults, here's the updates to the HandBrake ones.
+==== Base ====
 Do a simple x264 encode:
@@ Line 17: / Line 19: @@
 <code>
 HandBrakeCLI -e x264 -a none -s none --stop-at frame:30 -o handbrake.mkv input.mpg
+</code>
+HandBrake sets keyint to 240 and keyint-min to 24, while x264's is 250 and 25. HandBrake also sets the default CRF to 22 instead of 23. Therefore, tell HandBrake one to use same defaults:
+<code>
+HandBrakeCLI -e x264 -a none -s none --stop-at frame:30 -x keyint=250 -q 23 -o handbrake.mkv input.mpg
+</code>
+==== Level 4.0 ====
+HandBrake adds:
+<code>
+vbv_maxrate=25000
+vbv_bufsize=31250
+crf_max=0.0
+nal_hrd=none
+filler=0
 </code>
