I'm using a plain 'ol digital camera.It's a pentax.On the front it says: 7.1 Megapixels,7.1 MP,3x optical zoom,high sensitivity of ISO 3200,powerful flash and 2.5 inch LCD if that helps.The sound on my camera isn't clear?
The microphones on P%26amp;S cameras are just very low quality and cannot produce broadcast quality sound, nor can the produce broadcast quality video.





You can always do what the production companies do, that is add all the sound alter when editing.





Most video editing programs include tools that will allow you to do voice-overs, Foley, music and text credits. Windows Movie maker is one such program.





Next time, in stead of listing all the features of a camera, just give us the model number. Then we will have access to all the cameras features.
