I have videos that do not have borders on them. When I run them through Prism, they end up with borders and the iPhone 3G won't stretch them to full-screen like it does other videos (in fact there is no change at all in the video after clicking the expand/shrink button in the ipod video player). I've also verified that the borders are added in the preview window in Prism.
I'm using the following settings:
Output Format: MP4
Encoding Settings:
Video:
Compressor: MPEG4 (iPhone)
Average Bitrate: 768
Minimum Bitrate: 1024
Audio:
Compressor: AAC
Bitrate: 128
Video Output Options:
Resize Video: [checked]
Shrink or Enlarge the video to the selected size: [selected]
Width: 640
Height: 320
If I uncheck the Resize Video option in the Video Output Options dialog, then the borders go away... but if I'm dealing with a large video, shouldn't I need to be resizing it?
