In order to keep my video file sizes around 800MB or less I've found that I have to reduce the Bitrate. I've set the Frame size to 960x640. What is the minimum Bitrate that I can use to get acceptable quality and how can I get the video the fill the screen (is there a pan-and-scan mode )?

Hello,

Actually, minimum bitrate is not specified for iTouch 4. So, seems that you can set the one you need.

As for filling the screen, perhaps, you will need to correct aspect rate of input video in Advanced>Aspect Correction option, there you can also use Crop Scale option allowing you to crop video to fill the screen.

I hope it helps.

Best regards.
