64bit Benching

[juGGaKNot]

I want to make a 64 bit bench ( searched the web and only found 32 bit ones )

I'm thinking of using a y4m ( http://media.xiph.org/video/derf/y4m...am_1080p24.y4m or http://media.xiph.org/video/derf/y4m...2k_1080p24.y4m )

1 - How can i cut y4m files ?
2 - Do i need any special options ? ( i'm thinking of x264-64 --quiet --preset slow --level 4.1 --bitrate 4000 )
3 - Any other thoughts ?

Cheers.

1. avisynth + rawsource.dll can read y4m. and, avs2yuv or avs2pipe(mod) can output video as y4m.
2. Probably, it is good to use ”--demuxer y4m” and "--output NUL"
3. Since y4m is uncompressed format, the filesize is huge. You should take care about the HDD speed becoming a bottleneck.

Ok, will think about it, probably 30 seconds clip.
