Hi,

for a Hardwaretest I need a h264 sample with that hugh bitrate. With avisyntch/avidemux I cantīget anything bigger then 42mbit how it seams.

Can you help my finding a way to get my file

thanks, greetings michael

edit: would be very important, please help

But "Crowdrun" is not 1080p, it's 2160p. And if you downsample it to 1080p, then 60 MBit/s will be MUCH overkill for any decent H.264 encoder.

Anyway, you could take any 1080p source you want, optionally add some random noise and finally re-encode the result at a low quantizer (or a low x264 CRF value).

If you only lower the quntizer/CRF enough, it should be possible to generate a 60+ MBit/s H.264 stream yourself quite easily...
