MOD3 custom firmware for Firefly 7S with 90- and 120- degree lenses GO TO POST



Video modes table

Previous versions:
MOD2
MOD1

[nutsey]

I've added several new video modes to my 7S MODx firmware.

1. "3K30" - 2880x1620 30fps 16:9. RAW Sample

This mode provides the highest resolution for 30 fps.

2. "Superview" or "S_VU" - 2560x1920 30fps 4:3. RAW Sample

This mode provides the widest FOV to get all the details. The resolution is slightly lower than in 3K30.

3. CCTV video mode. 1280x720 10fps. 800/1200 kbps bitrate.
RAW Sample for 'High' bitrate setting.
RAW Sample for 'Low' bitrate setting with 'Black&white' enabled (note that it is not completely b&w due to the bug in original fw).
This mode can be used to replace a 720P HD security camera. It can record almost 3 days of video in 'low' bitrate (~2 days in 'high') with 32Gb memory card.

hey nutsey. I am using MOD3 firmware and I like 1080p60 best. But I tried 3k30 mode in a dark room setting (with small lamp light), and I set the Frame Preferred to ON, and Gyro OFF, and other settings were normal/default. Hey every 5th frame is a duplicate of the 4th frame. So the real frame rate is what...? uh 25 fps?

here's my sample video - https://yadi.sk/i/TWmlMVRy3RQtaw

also, when Gyro is ON, the 3k30 footage seems "slow" by %5 or %10. strange

could you set the frame rate to 25 real frames/s in 3k30 in MOD4 ? ... or what settings could I change to improve the 3k30 footage?

thanks for your work.

[nutsey]

So the real frame rate is what...? uh 25 fps?

I checked this mode with same settings and can confirm the problem... the real frame rate seems to be 24 fps.

I'll try to fix it. Thanx for reporting!

Hi, I would be happy to test.

Is there a way of getting rid of the Firefly 7s Logo in the Date/Time Stamp?

BTW I have the 120° Lens

[nutsey]

koronoo Hi, I need to slightly adjust some resolutions and bitrates and it's ready to be tested.

There is no logo in the date/time stamp for MODx firmware:


BTW could you take a macro photo of your 120-degree lens from different angles?

[koronoo]

Sure I will do in few minutes.
from your recordings I see that you are from Turkey as well.
selamlar from Kütahya.

[nutsey]

Aleykum selam from Antalya. I was in Kütahya several months ago. Very nice city

[koronoo]

[nutsey]

koronoo I don't have exactly same lens so could you check if 120-degree version works fine with gyro on?

[nutsey]

MOD1/MOD2/MOD3 video modes.

* due to firmware bugs bitrates for “high” and “low” settings can’t be different

H.264 video encoder works in ABR mode increasing bitrate when needed.

[petesimon]

for the bit rates above 30, and especially above 40, I highly recommend a PRO or EXTREME or similar good quality U3 speed sd card.
the front of the card will have a [3] symbol and will be UHS-I specification.

[nutsey]

Wi-Fi is not working with this FW! I will try to fix it in next MODx version.

Note: if your 7S camera has outdated firmware update to stock 0329 first.

[petesimon]

nutsey - awesome!
but I have ACRobin Zed2 030817 firmware now. Will your MODx update work okay?
thank you.

[nutsey]

Yes. I successfully tried flashing it in many different ways

[koronoo]

I will try those tomorrow and give some feedback, thanks for your efforts.

[nutsey]

You can try this firmware without flashing - rename file to FW96660T.bin and place it to your memory card. It will be loaded into memory on startup. Remove the card and reboot to undo.

[petro_ionut]

Can you please add an option to protect a video file from being overwritten in dashcam mode, that will be great, cam lacks this

[nutsey]

Unfortunately this can't be done at the moment.

MOD2 FW for Firefly 7S.

Changes: Added 'Flat' color profile. Improved 'B&W' mode.

[petesimon]

cool! thanks!

I wonder how many shades of gray are produced in the 'B&W' mode... hm?

is it possible to do a "Vivid" color profile in which the color-saturation is higher?

[nutsey]

8 bits equal to 256 iterations (RGB values are linked together for grayscale).

Sure.One of the existing profiles can be transformed to anything else where we can set Cr, Cb, Y, Saturation and Vibrance values...

[nutsey]

MOD2 demo: Default 'Norm.' (ex 'Color') color profile VS 'Flat'.

RAW video samples: Norm. / Flat

[petesimon]

'Flat' looks like some cheap Novatek 9xxxx cams and looks like most Allwinner V3(s) cams.

[nutsey]

Yes 'Flat' always looks flat and unattractive

[bruceballad]

I wonder if the "flat" option can be a little more useful as wide dynamic range footages like GoPro Hero's.
Since usually high end wdr camera footage look flat and unattractive without grading.
But you know, low contrast, WDR footages can be colour graded in the post process and get more high and low light details.

Edit: I just inspected sample footages and yes, clearly there are more details in the shadows with the Flat mode.

[nutsey]

bruceballad I also managed to get more details in highlights (as well as in shadows) with my custom firmware for GitUp Git1 cam. For some reason here I can't do that yet... Need to do more research.

UPD: Good news! I found a way how to improve highlights.
