The thing I like most about Android is the developer community. Together they do some really amazing things! Take, for example, the recent efforts of charansingh who has unlocked 720p video recording to the Nexus One.
Here’s a quick video I shot this morning. I recorded the video and uploaded it directly to YouTube, no intermediate video processing went into it, so it should show you what that hardware itself is capable of.
Here’s charansingh‘s video:
Unfortunately, you can’t just apply the hack and get 720p video recording on your stock Nexus One, this gets back to my earlier comment about the collaborative efforts of community developers. This hack sits on top of the latest test version of CyanogenMod ROM (CM5.0.8test3-N1) and builds upon the work of Cyanogen, maxisma, Wysie_Soh, barakinflorida, and coolcho3k.
The hack is still a work in progress. charansingh says better audio and an increased FPS rate are being worked on.
Standard disclaimers about not being responsible for damaging your phone or rendering it unusable apply.
How to install the 720p video hack
If you would like to get 720p recording on your nexus one you’ll need to root your phone, apply the radio from Froyo (see below for instructions on how to flash the radio using fastboot), flash the CM5.0.8-N1-test3 ROM from Recovery, then flash the 720p video update from Recovery.
