Xbox – way to Change how long the Xbox record time is

Using Fraps

Unfortunately video recording in-game, via software, usually requires a powerful PC. In order to increase the FPS you can try to reduce the resolution/details of your game

Hardware Solution

There are some hardware devices that can used to record your game video streams. They cost around 200$ and can be installed internally like

• Blackmagic Intensity Pro

or externally using HDMI, as for example

• Hauppauge HD PVR

Extra

Few engines have recording capability inside. One example is the Valve Source Engine used in the following games:

• Team Fortress 2
• Portal
• Left 4 Dead 1 and 2
• ...

In this case you can just open the developer console and write

record [demooname]

where demoname is the name of the file .dem the game will create.

In the case of Source Engine you will not have any FPS drop rate because the demo is stored in a special format that you have to rework later in order to create a video stream.

So, this tutorial has a review of recording devices, including ones that support HD recording. It does note the following

I WILL BE LISTING SOME HD COMPATIBLE RECORDING DEVICES that enable you to record in standard and play in High Def simultaneously later in this article. However the prices can vary dramatically on these devices. There is only one somewhat affordable external device that allows true HD capture and that is the Hauppauge HD PVR and it is listed below.

It also says

As far as I know there are no affordable external devices that record 1080p or from an HDMI cable. The Hauppauge will do HD but it will only record in 720p or 1080i.

Mind you, this guide was posted 3 years ago so there is no guarantee that the devices haven't improved since then, but this seems to be a very complete guide.

Honestly, I think you're going to find better support on the GameDev side of things. A lot of players record their videos (especially those in MLG) but a lot of the times they won't care about audio syncing, or perfect framerates. You can take a look at this guide over at the MLG forums, but a lot of their focus is on cheap rather than quality.
