Lynh Phan posted some photos on Facebook that show the guts of the X5 camera: Facebook This one shows the SoC (processor), which is marked "Ambarella A9-A1-RH". The Ambarella Data Sheet for the A9 SoC doesn't mention bit rates, it but it does say: On the H.264 Wikipedia page, BP is "Baseline Profile (66)", MP is "Main Profile (77)", and HiP is "High Profile (100)". But it is the "Level 5.1" that has me hopeful. On the Wikipedia page again, under "Max video bit rate for video coding layer (VC) kbit/s", under level 5.1, it specifies 240,000 for BP and MP, and 300,000 for HP. That's 240 and 300 megabits/second, respectively. And if we move down to Level 4.2, we find that the max bit rate for HP is 62,500 kbit/s, or about 60 megabits/second, which is what we are getting from the X5 right now. So my hope is that the X5 camera is currently not asking the Ambarella chip to do all that it can, and that the Ambarella chip can be unleashed in a future upgrade.
