I have several 5 minute video clips with a 5 second gap in between each one. When rendered & burned to a dvd, I noticed when checking out the bitrate the first few seconds of each clip jump to around 9.5 before going down to around 7.0. It was rendered with Main concept with a variable bitrate. The only change I made in the template was to kick up the average to 6,000. The audio is PCM since audio & video quality on this project is important. Any ideas why it jumps at the beginning of each clip so much?
