Monster Compressor!
 

Original Black Box Compressor they Compressed MotoGP 14 18.4 Gbs to 6.5 GB What is kind of Compressor is that.. i tried precomp 0.43 i compressed 9.3 Gbs.

Anyone here knows Monster Compressor?

have you checked if there are files bik, maybe they also compressed video files bik :)

Some changes...
 

Use precomp 0.40 or 0.38 and use precomp -slow -s130 swich for it and use lzma64:max and try to open the motogp bin file of blackbox using free arc and see which parametre of lzma they used and also to know srep:?....... and see the size of video files with original and language ripped;);););)

@Dante1995's and Alash Als the Video and Audio is Lossless i try to install its back the original Size 18.4 Gbs

you should try precomp043 -cn -intense without media files. example: .wav .bik .mp3 or sound/video folder. next use frearc 0.67 with -mx that would be highly compress ever...B)

open the file that blackbox compress ( the free arc source ) & send me aphoto of information on it like this :
