MOD1 compared with stock V69 (V1.0.69) in 4K30 video mode (MOD1 is below):



Fullsize PNGs: MOD1 FW / Stock FW (10+Mb each).

[nutsey]

MOD1 bitrate table:

'Normal' (Low) - direct uploading to youtube,
'Fine' (Med) - video storing as is,
'S.Fine' (High) - editing and/or re-encoding.

1080p120 bitrate values are 17 - 35 - 70 Mbps for MOD1.

Very nice, no sharpening?

What else is possible? Custom menu items, flip picture, real 1s timelapse, etc?

[nutsey]

Actually it's not only 'no sharpening' here. This FW includes several dozens of tweaks for things like coring, anti-aliasing, ISO, black level, highlight compensation and so on.

Hello, is it for U or V version of camera?

[nutsey]

It's for V. The 'U' version is also ready, but I can't test if it works fine.

[relaxman]

Thanks,
can you list the available commands which 8S can understand?
I like to use auto recording when external power connected, but my cams with U fw. freeze after 2 sec, my V don't freeze.
External power is from 5V 3A DCDC converter. I don't know whats the difference between V and U besides DDR type.

BUT when i disable car mode or quick capture, just power on the cam, and start record manually, U cams also doesn't freeze.
So i like to know the command for: delay 5 sec, then start rec.
And i'm interested in other commands too, if possible please share.

thank you!

[nutsey]

You can use this script to get the list of supported commands: https://www.goprawn.com/forum/ambare...t-for-a12-cams

[nutsey]

And as usual don't forget to use full-range RGB:

'Video - Decode Format...' in VirtualDub.

[nutsey]

If you can't connect your Firefly 8S to Android App use the 'autoexec.ash' script which fixes the problem (see the 1st post above). Note, that you need to be registered GoPrawn.com user in order to download direct links here.

Ok, so, i need to put the bin on sd card, then use the normal procedure for Fw upgrade. But what about the fix? How do i use autexec?

[nutsey]

The script file ('autoexec.bat') should be copied to the root of your memory card. It will be loaded each time when the camera boots up.

[Anuku]

ok thanx. Will try

Nutsey, could you please up the bitrates a bit? Especially 1080/60, 1080/120 and 2k/60? Similar to what ILDAR mod had (1080/60 at 60Mbps, 2kk/60 at 80 etc.)? It makes huge difference used in very fast movements - 36 vs 60 Mbps for example.

[nutsey]

Sure. Can you provide the full list of bitrate values for all modes?

Maybe I can increase the bitrate on the modified firmware. Do I need to make it as before?

[kubais]

Here are mentioned bitrates from ILDAR´s mod. I checked those from 1080 and up and all seem to be working fine. The only thing I am missing is upped bitrated of 1080/120.

[nutsey]

Actually the bitrate for 1080p120 is already increased to 70 Mbps... I forgot to change this value in the table above.

[kubais]

Would it be possible to make other changes apart from upping the bitrates? Mod made for U version as well?

[Q100]

It's for V. The 'U' version is also ready, but I can't test if it works fine.

I can test your Modded Firmware U69. Where can I download it?
