Chronos User Discussion / Re: Chronos 1.4 RAW conversion tool - pyraw2dng
« on: February 18, 2019, 09:32:50 AM »
I can't decode 12 bit compressed RAW format.
When trying to convert it the output DNG files contain color noise and sometimes something similar to out-of-sync frames.

Tested both options '-d' and '--oldpack'; resolution specified correctly; RAW files saved with firmware 0.3

Are you able to use 0.3.1-RC1 instead? It can natively record videos in CinemaDNG format. http://forum.krontech.ca/index.php?topic=434.0

What do you mean by color noise?

The readme says that the old RAW 12bit format has bugs that cause color corruption:
The --oldpack option will attempt to decode the raw file as a 12-bit packed format generated from software versions v0.3.0 and older. However due bugs in this encoding format, there may be off-by-one pixel errors in the encoded files. This is most noticeable as colour corruption after demosiac.

Some footages already in RAW 12bit so it will be good to convert it but if it does not work out - nothing terrible.
