How can i make a trailer for my app?

Is there anything i can make trailer for my upcoming realest of my game app.

 

We are using screenflow. You can use the BB simulator and capture the screen and then edit it and export.

 

I'm a big fan of Reflector for recording gameplay by mirroring it from your device.

 

If you are using a Mac, you can record your gameplay with QuickTime mirroring it through wifi.

Here is a detailed tip:

I record the game on Windows with FRAPS and then edit it with Sony Vegas Pro 9.

 

I often use Joyoshare Screen Recorder to record how-to videos of my app for my customers. It is able to record screen in HD quality with no lag. No watermark and no time limit. Maybe you could give it a shot.
