Re: EVO Pic/Vid samples [Videos Up]

Guys just remember, Qik and the Android camera app record at terrible bitrate, despite being 720p. Bluray is a max of 48 Mbps(Mebibits per second). That's (we'll use binary since I'm not sure if it's Mebi or Mega, we'll assume 2^x for all our bits here) only 48/8 or 6 MBps(Mebibytes per second).

According to The SD Association a class 6 SD card can do a minimum of 6 MBps sustained. That's enough transfer speed to write a full blu-ray quality video to the card, sustained.

So what does this mean for us? It means that unless these apps are hitting the limit of Android's filesystem driver OR the limit of the snapdragon CPU (I doubt this) we should (I hope? Unless writing camera apps for Android isn't possible, but after hearing that Skype and Qik did it, I imagine it is) see higher quality compressed videos (by increasing the bitrate) sometime after the EVO hits market. I read somewhere (here, at Giz) that the bitrate of the current recordings are 5 Mbps. That is less than 1/8 what is possible with the storage medium. I'm willing to bet that if the Snapdragon can decode high bitrate that we can definitely get a higher bitrate on record. It's just a matter of time.
