Will the movie with the Pentax k-x show on a large screen?

I wasn't sure how to title this one. Right now I have a point and shoot canon that does 640x480. I have an HDTV. If I take the video from the Pentax k-x that was done in 720p and show it on my tv, will it appears as a regular full screen video...like any other 720p video? Assuming the video is clear, will it somehow become grainy because I show it on the big screen? Thanks.

The K-x does not have HD video out. To play back at 720p you have to transfer the video to a computer or media player, like an Apple TV or WD TV. The videos are encoded in MotionJPEG so they might have to be converted to something the media player can play.

Basically, yes. If your TV is 720p and the video is 720p it will fill it properly, without stretching or black bands. I guess that's why the standards were created, so you know it will work!

It depends on what you mean. If you blow the same number of pixels up much larger, to a huge screen, then you will be able to see the pixels instead of having them fuse into a perceptually smooth image. Is this what you mean? It is unavoidable except by sitting further back from the screen. But there is nothing about the camera that is making it more "grainy".

Use with confidence!
