One thing I'd be on lookout for, is storage. Recording uncompressed video requires fair amount of bandwidth, and compressing it requires great amount of processing power, so you'd be capping the bandwidth or processing power. According to Wiki, Uncompressed data rate = color depths * vertical resolution * horizontal resolution * refresh frequency. So: 8 Bit @ 640 x 480 @ 15 fps = 4.5 MB per/sec, or 15.4 GB per/hr. 8 bit @ 720 x 486 @ 29.97fps = 20 MB <http://en.wikipedia.org/wiki/Megabyte> per/sec, or 70 GB per/hr.
Please note, that provided values are Megabytes, not Megabits. It might work well with greyscale, higher class SD card, or maybe CPU even would be capable of some basic near realtime encoding(not sure about it). (But take with grain of salt, I'm just speculating as well) On Tue, Apr 15, 2014 at 4:39 PM, Mark Rogers <[email protected]> wrote: > On 11 April 2014 22:12, Bartosz Dubiel <[email protected]> wrote: > > Tell me if I'm a fool to hope little Pi is going to manage so much. > > I think it's difficult to give you a useful answer to this, having not > tried it.
