you did not understand me correctly i said i want exactly this quality of this guy
...
and i have the same camera also i should get the same result..... how did he do it?
He did it linking multiple very short shoots, each one with a lenght of only few seconds. This way he is recording using only the camera's memory buffer, that is a lot faster than the SD card interface, but has a very limited capacity, only a few seconds of Full HD raw video.
If you want to shoot with the same quality for longer times, you cannot do it with the slow card interface your camera has. You need a camera with a CF card interface.
50D, 5D MkII and 7D MkI have a CF card interface capable of raw recording at 80 MB/s if you use a very fast CF card. This allows continuous Full HD 14 bit raw recording at 20 FPS.
The 5D Mk III has an even faster CF interface, capable of 100 MB/s. This allows continuous raw recording at Full HD 25 FPS
