Inefficient file I/O



I am trying to use QuickTime for Windows SDK to write uncompressed video to a QuickTime movie. I have the video compressor set to "None". The video frame size is 720x480. By looking at the performance counter, I notice QuickTime is writing 64k bytes of data in each I/O operation. And the number of writes/sec is over 300. I am wondering is there a way to optimize the performance? Maybe a custom data handler? But I am not sure where to start.
