hey guys, anyone up for a little game? as most of you know x264 enjoys a reputation for being a fast encoder, in large part derived by the encoding speed achieved with the ultrafast and superfast presets. but can any of you guess how slow it is when you crank all the settings up?
i took a 4 min 10 sec vc-1 @ 12mb/s, 10920x1080 with 128kb/s 44.1khz 16bit wma v2 audio muxed in a wmv container.
i targeted an mkv container with aac audio, 128kb/s 44.1khz and for video i used x264 configured as follows:
reference frames = 3
b-frames = 3
gop = 250
closed gop
motion search = tesa
search range = 32
high@4.1
min quantizer = 0, max quantizer = 30
debocking filter = -2,-2
direct mode = auto
2 pass vbr
12 mb/s
weighted p = 2
weighted b = 1
partitions = all
chroma m.e. = 1
adjusted b = optimal
sub me = 10
trellis = 2
adaptive quantization = auto (2)
AQ strength = 2
psy-rod/psy-trellis = 1:0
lookahead = 250
qp curve compression = 1
mixed references
mb-tree = on
no fast p-skip
no dct decimate
non-deterministic
as you guys can see this is about as aggressive as you can get with x264 settings, i could have used sub-me = 11 and a search range of 64 but that would slow things down way more and in all honesty these settings are probably the highest quality you can get from x264.
so, here's the game: how long do you guys think it took this system, win 7, i7 3770k @ stock clock, 8 gb dd3 to encode a 4 minute 10 second clip? as i don't want to make it too easy for you guys, i won't give you any choices, i want to see if anyone has a guess that is reasonably close.
btw, this test encode clip will be going into a backup as i want to see how divx's hvec does both quality wise and speed wise when x264 settings are maxed out.
edit: doesn't this forum allow us to insert html tags into our posts? i was trying to add the results in a spoiler format or as really small text, but i can't seem to do it.
