Does anyone know if vision+ camera has ambarella chipset inside? Maybe A5 or A7? It's just an idea but if the chipset is based on ambarella, it might be possible to use the "ambarella firmware toolbox" to modify the bitrate?
I opened an conversation about possibility to crank up the FC200 bitrate on another forum where discussion about firmware modification of Ambarella based cameras is going on....It's a great thing to try...someone witha broken gimbal but with camera that work could try...
1/ What is recommended value change to ? (from 15 to ???)Hmmm.... I did some googling and found out that ambarella has provided chips for DJI Phantom 2 cameras.
So, I downloaded the Ambarella firmware toolbox and opened the FC200 firmware.bin using it and I was able to extract the firmware onto harddisk. I tried the bitrate editor and I saw values (15) matching the video bitrate of the camera!
So, I could edit these values and compile the firmware and it might work.... Other chance is that it will brick the camera.
Anyone brave enough willing to try? ;-)
I think yes because is based on the latest firmware but is just an opinion1/ What is recommended value change to ? (from 15 to ???)
2/ If I'm correct, if flashing with i modified firmware will be unsuccesfull and camera will not work, always is possible to re-flash with original firmware ?
Great! I can't wait to hear how are the results. Now that I know that it will not brick the camera I will upgrade my camera later today.Upgraded my Phantom camera to modified firmware. Upgrade went OK, camera working OK so far (in house testing only). Will try to test today in the evening in real fly.
We will compare results then : IMO camera producing much better picture now. Only one (hope minor) drawback I noted so far: it became much hotter after 15 mins of filming (but it's understandable: much higher bitrate), but with more cooling during fly hope it will not be a problem.G

IMO video dynamic range is a bit wider, not very significant, of course. It can be useful in post production to make a better final video.To be honest.. I cannot see no difference from the movies I do with mine.
the only sure way to test it, is to fly 2 birds side by side at the same time, with the same conditions, with the same cameras, one modded, and one stock.
