Editing Functions
• If you convert AVCHD movies with a frame rate of 50i, the
frame rate of the resulting MP4 movie will be 25P.
• After repeatedly recording and deleting scenes (fragmented
memory), MP4 conversion may stop working correctly.
• Scenes recorded using different frame rates cannot be joined
into a single scene during MP4 conversion.
