About QuickTime Video Settings
A:
QuickTime video settings
You can choose the following settings for the video portion of your exported QuickTime movie. * Settings: Click this to adjust the compression used to export your video track. * Filters: Click this to add and adjust additional video filters. * Size: Click here to set a size for the movie. Settings: * Compressor: Select a codec to compress the video. All the standard Final Cut Pro and third-party video codecs installed on your system are available. Some codecs let you choose additional options, such as bit depth or color versus grayscale. * Quality: Adjust the slider for the level of spatial compression you want. Some codecs may not allow you to choose this setting. * Frames per second: Define the frame rate of your exported movie. This doesn't need to match the frame rate of the clip or sequence you're exporting. The file quality is improved if your new frame rate is evenly divided into the original one. * Key frame every_ frames: If your selected codec uses temporal compression, you can select the rate. Increasing the number of frames between keyframes increases the amount of compression and makes the final file size smaller. Depending on the codec you use, the movie file's quality, especially for clips and sequences with a lot of motion, may decrease based on the number of keyframes specified. Other codecs, such as Animation, are lossless, and there is no loss of quality. A setting of one keyframe every ten frames is a good starting point. Note: If you're exporting a high-resolution movie for broadcast, consider avoiding the Keyframes option since it's generally not used with material for editorial purposes. * Limit data rate to: With some codecs, you can enter a target data rate for your compressed QuickTime file. The codec uses a combination of spatial and temporal compression to try to reach your target. Be aware of your frame size and frame rate so you don't set an impossible goal and possibly get disappointing quality in the visual image. * Options: Click here to set additional options, if the selected codec supports them. Filters: QuickTime filters apply to your entire exported clip or sequence. This is different from applying a filter within Final Cut Pro, where a filter is applied only to selected clips or parts of a clip. For more information on QuickTime filters, visit Apple's QuickTime Web site at www.apple.com * Load: Click here to use a filter you've saved, such as one used in an earlier project. * Save: Click here to save a filter's settings, if you might use them again. Size: You can use the current frame size of your clip or sequence or specify a custom size. Note: It's a good idea to keep your frame sizes divisible by four if you're using highly compressed codecs such as Sorenson or Cinepak.
