PTP Debug codes in Z7 are different from that in DSLR ,
0xF036 looks like memory dumping , 0xF037 looks like memory writting .

Interesting that they repacked the code space, but I guess "its a different model" so not part of a family so they can reclaim numerical space...

I traced VideoFourCCCode( PTP PROP code 0xDE9B) and VideoBitRate (PTP PROP code 0xDE9C) ,
then find setting data for H.264 module .
Meanwhile , based on H.264 interrupt Handler , i'm sure that 0x24070000 is base ADDR for H.264 encoder/decoder .
To do :
Identify VideoBitRate register number in H.264 mudule , then try higher 4K Video bit rate .
but i just wonder whether it's meaningful to increase it , or to say maybe nobody needs higher bit rate for H.264 4K video ,
since 4K Video bitrate is very high now .
