I think some parts of encoding can be made parallel, and some parts can't.

So you CAN make it parallel, but it's probably very hard, and it may not work that well, because the parts that can be made parallel will probably be bottle necked by the parts that can't.

Intel Core™ i7 Quad Processor i7-920 4,8GT/sec, 8MB, Boxed

Intel DX58SO, X58, Socket-1366, ATX, DDR3, QPI, GbLAN, 3xPCI-Ex(2.0)x16

Corsair TWIN3X 1333MHz DDR3, 3GB, Kit w/3x 1GB XMS3 modules, CL9-9-9-24

Ah, ok.

dunno if you can see this image,. but if you look closely you see H.264

Don't know, it's most likely not, but something that's very important (in terms of speed) is the settings.

This

Code:

x264 --crf 10.0 --ref 16 --mixed-refs --no-fast-pskip --bframes 16 --b-adapt 2 --b-pyramid --weightb --direct auto --deblock -1:0 --subme 9 --trellis 2 --psy-rd 1.0:1.0 --partitions all  --8x8dct --me tesa --merange 64 --threads auto --thread-input --aq-strength 0.5 --progress --no-dct-decimate --no-psnr --no-ssim --output "output" "input"

is like 50 times slower than this

Code:

x264 --crf 40.0 --nf --no-cabac --subme 1 --no-chroma-me --partitions none --me dia --merange 4 --threads auto --thread-input --aq-mode 0 --progress --no-psnr --no-ssim --output "output" "input"

So you see, comparing speed directly without knowing what settings and everything is not very accurate...

Sorry I haven't watched the vid yet, (have to wait for tomorrow for that), so I can't make comments directly based on it.

Ok, going to sleep. 1:43AM.

Threaded Mode \| Linear Mode whot do you guess??
