Kamcord, the startup offering a free SDK that makes it easy for iOS devs to offer in-game recording functionality to their users, today is announcing some pretty big updates to the service. Since grabbing $1.5 million in seed funding from some notable investors back in December (Andreessen Horowitz, Google Ventures, Yahoo! CEO Marissa Mayer, and others), the Y Combinator-backed service has experienced some significant traction and the team is adding plenty of new features to stay ahead of the competition.

Kamcord-iPad-01The big new feature being announced is voice overlay functionality that will allow users to narrate their videos while they play, as demoed by the team in the video above. CEO Matt Zitzmann also provided us with some other updates the team has added in the last month, including: Video trimming, a custom UI / white-label solution, and a new “Gameplay of the week” notifications feature.

Also being announced today: Kamcord has recorded over 500 million gameplay videos in the last 6 months alone across the 100 apps its currently deployed in. One those games includes the latest from Chillingo and Zitzmann says the company is talking to all the other big mobile game developers too.

While there is some competition out there, (Rovio decided to use competing service Everyplay in its latest Bad Piggies title), a lot of devs are choosing Kamcord and Zitzmann gave us a few reasons why.

Matt explained the Custom UI / white-label solution “is important for the large game developers since they want Kamcord to feel like it’s part of their game. Not a app within an app” like the competition.

Kamcord is hoping the new voice overlay feature will drive growth among users sharing their videos to social networks. Users can already share through Facebook, YouTube, Twitter, and Email, but the company is also planning its own social community that will allow users to upload and browse gameplay videos from all apps using Kamcord.

That, and Android support, will be the two big priorities for the team going forward.
