@hamed,
Raw aspect of video stream from IMX071 is 3:2 , current 16:9 movie stream and HDMI video are cropped and resized from 1664x1088 3:2 to 16:9 1920x1080
or 1280 x 720 , i think it's easy now for us to crop and resize 3:2 to 2.35:1 .
Regarding dual card storing , good idea , it absolutely increases saving speed , i don't think it difficult for us to implement it .

please dont forget about us who use 3:2 when developing the patches :)

it would have been great to had the uncropped 3:2 hdmi hack available for external recording
or a 424p hi bitrate option


thanks so much for all the hard work everyone

@leegong
and what about "pixel-bining".in your opinion is it theoritically possible for creating pixel-bining instead of line-skipping by changing firmware? or this is a hardware limitation?
I have read that with pixel-bining it is possible to increase dynamic range about 1-2 stops and inhancing low light performance.

in 1.5x crop mode with 2*2 pixel bining we can reach fullHD resolution.

Help for RAW video hacking needed

Postby leegong » Thu Jun 18, 2015 8:22 am

Here's the ins and outs :
Data for Nikon TAG 0x2C comes from mem 0x8F86CBD4 and struc_156 , which are strongly related to struc_79.field0x64 ,
which is pointer for 0x4000D848 register , i suspect that they are responsilbe for LV AF or LV AE , so it's helpful for LV RAW hacking
to understand Nikon Tag0x2C , maybe it's possible to force chip0x4000D848 output LV RAW if we hack it .
So if anybody is willing to help for LV RAW hacking , let's work together to decode Nikon TAG 0x2C , you need an EXIF viewer software,
for example Free ExifTool by Phil Harvey, then get Nikon tag0x2C
as many as possible under different setting , then we analyze and guess what Nikon tag0x2C means .

@Silverwolf , sorry , i have no idea about why no Tag0x2C in EXIF ,
there are codes for Tag0x2C in firmware , maybe Tag0x2C is only valid
for specific setting or image type .
