Hey Guys!
Firmware for GIT2P 90 has been modified in order to enhance existing functionality and add new features. Most notable changes are improvements of image details in most video modes, manual settings for ISO and Shutter speed for video (now sets max level limit), usable JPEG photos due to updated filtering settings. Please check detailed list of changes under the spoiler.
Update: PAL video modes added (50fps, 25fps), video bitrates doubled (32Mbps, 55Mbps, 67Mbps), 1080p60 image details improved and more.
Update (2018-12-06): New version with better sharpening, AWB and other IQ improvements.
Update (2019-03-09): Updated color correction settings and switched 1080p60 to 59.94fps to avoid periodical frame dropping and doubling. Experimental support for git2p 170° FOV added.
Update (2019-04-20): Fixed issue with EIS for 1080p60
Update (2020-04-02): New version of mod developed from scratch based on v1.3.
Update (2020-10-15): Updated AWB, color correction, sharpness and gamma.

Git2P 90/170 firmware mod (based on official v1.3)
2020-10-15
1. Updated gamma curve for normal contrast.
2. Updated sharpness parameters.
3. AWB tuning.
4. Color correction settings updated.
2020-05-07
1. Updated gamma curve for normal contrast.
2. Updated codec settings.
2020-02-08
1. Fix for "File error" for .mp4 with fullrange flags.
2020-01-31
1. Framerate set to 59.94 for 60fps video.
2020-01-16
1. Doubled bitrates for video (Low: ~32mbps, Med: ~55mbps, High: ~67mbps).
2. IQ-related updates (sharpness, Gamma curve for Normal Contrast, Color Correction, NR).
3. ISO Limit feature added for video (set ISO value with Shutter Speed Auto)
4. Photo Mode changes: ISO50/100 with Auto Exposure support added, NR parameters updated.
5. 1080p60 without EIS is cropped by ~8% due to hardware limitations to avoid image scaling. 1080p60 with EIS has no additional croopping or scaling, but make sure EIS is enabled BEFORE record start.
6. Added FullRange and rec.709 flags to mp4 header.
7. Video resolutions changed:
2160p24 -> 2880x1620x30
2160p24 4:3 -> 2304x1728x30
1440p30 4:3: changed sensor mode to use full FOV
1296p -> 1080p30 (full readout, better details, less artifacts, more jello)
1080p30: no scale to intermediate resolution during processing, less jello, binning artifacts
1080p60 4:3 -> 1080p50 (16:9)
Git2p 90 firmware mod (based on official v1.2) (OBSOLETE)
2019-04-20
1. Fix issue with broken EIS for 60fps modes.
2. AE and AWB settings adjusted.
3. Change Effect Sepia to convert from full range to limited range (same as Black&White) with increased saturation.
2019-03-08
1. Changed video framerate for 1080p60 from 60fps to 59.94fps to resolve sensor sync issue.
2. Updated color correction settings.
3. Automatic exposure settings adjusted.
2018-12-06
1. Sharpness settings changed: Strong - same as original Normal; Normal - external edges disabled; Soft - sharpening disabled.
2. Changed params for Auto WB.
3. AE params and gamma curves adjusted.
4. Color correction changes.
5. Changed sensor mode for 1440p 4:3 (1920x1440x30) video resolution for full FOV from sensor.
6. Better support for photos with manual ISO and auto exposure (ISO100 should work properly now, but no ISO50 and ISO1600).
Known Issue: Shutter speed is not working correctly with ISO Auto (ISO3200 max) for video. Set ISO50, if you need ISO3200 as max, in order to use shutter speed settings for video.
2018-11-07
1. Replaced 1440x1080x60 (1080p60 4:3) video resolution with 1080p50 (PAL) (1920x1080x50).

4. Replaced wvga (848x480x30) with 1152x648x30 (1/4th of sensor, half of 1296p).
5. Updates for 1080p60 and zoom settings for it for better image details (zoom x1.2 is cropped to match video resolution).
6. Reverted GOP size to 15 frames.
2018-08-12
1. Changed sensor mode for 1296p video resolution to improve image details.
2. Increased GOP size to 60 frames.

2018-08-03
1. Switched sensor mode for 30fps video resolutions (except 1440p, 2160p) to improve image details.
2. Adjusted settings for noise reduction filter. JPEG images from camera should be more usable now, same as fine details in video should be less blury.
2018-07-31
1. Sharpness filter is completely disabled for "Sharpness: Low" setting.
2. ISO setting for video now works as max ISO used by Auto Exposure.
3. Shutter speed setting works as limit for min shutter speed (value depends on Frequency selected - 50Hz/60Hz):
1/30 - works as previously
1/48 - 1/50
1/60 - 1/100(50Hz) 1/60(60Hz)
1/120 - 1/200(50Hz) 1/120(60Hz)
1/240 - 1/400(50Hz) 1/240(60Hz)
4. Target value for AE algo has been risen to make picture brighter.
5. Adjusted NR params to make it less agressive.
6. Image effect "Black and White" has been changed to adjust video luma component to limited range.
7. Disabled one of the image filters which caused too much of motion blur and strange effect of color delayed by 1 frame noticable in low light or on fast movement with high shutter speed.
8. Adjustments for AE curves to avoid frame skipping in 60fps+ video recording modes and reduce motion blur in 30fps modes.
