      this thing should be equipped with an Ambarella chip-set instead of Novatek.

      Git3 will probably be renamed to G3 Duo.

            GitUp confirmed that some of 3rd party dashcam external camera modules with IMX323 sensors can be compatible with G3 DUO.

                Custom firmware for the G3 cam by hc1982 (based on 90-degree v2.2): https://drive.google.com/file/d/12Nf...ew?usp=sharing

                Changes:

                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 curve for Normal contrast adjusted.

                4. Color correction changes.

                5. Changed sensor timings from 29.97fps to 30fps, 59.94fps to 60fps to match recorded video framerate and avoid frame doubling/skipping.

                6. Doubled bitrates for video (Low: ~32mbps, Med: ~52mbps, High: ~70mbps). Make sure your sd card is fast enough.

                7. Adjusted settings for noise reduction filters.

                8. Image effect "Black and White" has been changed to adjust video luma component to limited range.

                9. Replaced 1440x1080x60 (1080p60 4:3) video resolution with 1920x1080x48 (1080p48)

                10. Replaced 1296p30 video resolution with 1920x1080x50 (1080p50)

                11. Replaced 2160p24 (16:9) video resolution with 2880x1620x30 (1620p30)

                12. Changed sensor mode for 1440p30 and 1080p30 video resolutions.

                Hi!
                Is it possible to look at the photo timelapse interval values in the firmware ? And how ?

                I bought a G3 Duo to test it and perhaps use some more to replace my custom Yi2K.
                I made a quick test today, in timelapse mode with a 0.5s interval. The result for a 1435 seconds duration is ..... 1435 images. Something seems buggy !

                I think I will test this firmware, as I am not completely satisfied with the still picture quality.

                Other things about this cam :
                - Still no SubSecTImeOriginal Exif value
                - The cam always start in video mode, there is no setting to choose the startup mode
                - The android app crashes a lot

                  Changes in modded firmware are mostly related to video recording, although some of them, like AWB, Sharpening and color correction changes should have impact on photos captured too. But, I believe, it behaves in the same way as original firmware, as no changes have been done for photo mode yet. I have tested my camera, and it looks like capturing one 12M photo takes ~2-3 seconds (it was tested with date stamp on). I believe, interval is between previous still capture completed and next capture triggered.

                  Thank you for your answer.
                  What is strange is the exact correlation: 1 pic per second. It looks like 0.5s interval is coded as a 1s interval. It could be a mistake in the firmware.

                  If it's a hardware limit, it's very disappointed as other action cams like the Yi 4K can do it. The old Yi2K can do 0.5s interval too, but without metering between each capture.

                  I think there is a bug in the firmware.
                  Using http://www.stemani.fr/clock_css.html
                  settings -> real interval
                  0.5s -> 1.5s
                  1s -> 2s
                  2s -> 3s
                  5s -> 6s

                  I'm gonna trying to contact the Gitup support

                  Hey guys, what do you think of this camera going now for slightly less than 100$? The other one I'm mostly interested in is the Firefly 8SE, but in that case I would wait for a price drop to about 100$, since the Firefly X should be on the way and I don't want to overpay for it...

                    I had Firefly 8SE previously. It is able to shoot video in 4K30, 2.7K60, 1080p120 etc, but I was very disappointed with image quality in 1080p30/60 (looks like image is processed in 2.7K for everything except 4K, so it seems to be optimal resolution, but scales not well into FHD) and low light recordings. It was critical for me, as I shoot video mostly indoors.
                    Now I have Git3, which has the same sensor IMX117, but less capable processor, so no real 4K, and only 1080p60/720p120, although no binning/skipping for 1080p30/60, so details are very good, 1440p30 is good in bright light, and 2160p24 is useless due to jerky video. It has more options (manual ISO, shutter speed in video mode etc), supports additional GPS module and secondary camera (personally I do not use them). Git3 suits better for my needs, especially with some firmware tweaking, as I do not need 4K at the moment, and Git3 records nice 1080p video, with acceptable level of noise and bright image even in dim light.
                    Firefly 8SE supports higher resolutions and framerates. Touch screens seems to be similar, build quality is more or less equal, but FF8SE is made of some soft-touch plastic and feels better. My FF8SE had some issues with hdmi port, so it was working only in specific positions of cable, while my Git3 has misaligned lenses and it produces soft left edge of image, quite noticeable with higher resolutions. Both cameras are not perfect and have some strong and weak points. Another option to consider is SJ8 Plus, which has the same IMX117, but newer Novatek chip, which supports 4K video (video produced with ntk chips looks better for me, compared to amba), and similar price if good discount is available.

                    Well, many thanks for the detailed reply, that was very helpful since I mostly grab 1080p and take stills (what about them?).
                    I was also considering che SJ8 Plus as another contender, it's close to the others in terms of price right now. I didn't understand if external mic is working or not, because it looks like a nice feature to me, not mandatory though.
                    On the Gitup G3 Duo I've read that the internal mic can't be switched off without physically disconnecting it from the board, but I think it would be a minor issue to me. It has the plus of a modded firmware, while for the Firefly 8SE I would probably get the current Vxxx version which has no mods.
                    The newer chipset on the SJ8 Plus is a good plus, being in the same price range. Well, I think I should look into some comparisons between SJ8 Plus and the Gitup G3 Duo 🤔

                    hc1982 Thanks for the idea for the next 8SE fw MOD! I'm going to turn the binning off for the 1080p30/60 video modes.

                  UPDATE 2 of custom firmware for GIT3 90° is ready for testing: https://drive.google.com/open?id=1i_...bSkGlNRX9wSFvz

                  Changes:

                  2019-02-06

                  1. Fixes for ISO50/ISO100 issues in new sensor mode used for 1080p30/1080p48/1440p.

                  2. Tuned noise reduction settings to improve image details and reduce noise level in low light.

                  3. Changed sensor timings for 1620p30 and 2160p24 modes to avoid frame doubling/skipping.

                  4. Added missing support for VGA 240fps video resolution.

                  5. Adjusted parameters for AE for all modes in order to improve highlights in bright light and avoid frame doubling in low light (720p120/VGA240).

                  6. Lowered compression level for .jpg photos for better image quality.
