Hello, I have the following MacBook: * 2.16GHz Intel Core 2 Duo * 1GB 667 DDR2 SDRAM - 2x512 * 120GB Serial ATA @ 5400 rpm I am working on a movie project in Final Cut Express and was given an HD file to incorporate which has the following specifications: Format: HDV 1080i50, 1440 x 1080 (1888 x 1062), Millions 16-bit Integer (Little Endian), Mono, 48.000 kHz 16-bit Integer (Little Endian), Mono, 48.000 kHz FPS: 25 When I open it in Quick Time, Final Cut Express and iMovie I get audio but no picture. Also, when I launch Quick Time, I get a message that Quick Time is missing some additional elements and directs me to this site: http://www.apple.com/quicktime/resources/components.html?os=OSX&ctype=696d6463&csubtype=68647633 I watched some HD videos off the Apple site and they played just fine, even the 1080p ones. Am I then missing a codec? Does anybody have any recommendations on how to get the video to play and show in Final Cut express as well. Thank you in advance!
