Excellent work, like all your materials.

Bitrate compare only in motion and on complex scenes, control sun, trees, grass, foliage, it can be a road in the forest. With regards to the card, I have 4 months working at the maximum bitrate 28mbit, no problems.

Nice tutorial, maybe this will get Novatek firmware modding more popular (as Ambarella was once)

Maybe I've missed it but as far as I remember (haven't touched Novatek way too long ) there are 46 bytes between partition 1 and partition 2. These bytes contain information about the next partition (partition 2 in this case).
By merging the two partition files using copy /b the 46 bytes get lost. Therefore I'd guess that if the firmware file is valid and gets flashed it will only flash the first partition. The second one will fail since the 46 bytes metadata are missing. It probably doesn't matter since I can't remember any mods affecting the second partition

Oh btw how did you find out about sharpness modification and any chance you can share some information about it?

Does latest bfc4ntk have an issue with the A119S firmware binary (I can't unpack it)? Trying to set up my Novatek environment but seems like nothing works anymore Can't even use bngui (which uses an older bundled version of bfc) due to some JavaFX lib issues

Edit: Seems like I don't even know how my own tools work any more... So bfc will receive an update to handle multipart binaries better

Will you support the VIOFO A119-G V3 as well with your MODs?
