I've just flown over my brothers house!
Rick Churchill I intend to send the recording to him in Australia. Can anyone tell me how my recording of the flight made in 1080p as a 806 Mbyte mp4 file, when put into Final Cut Pro and edited down from 20 minutes to only 8 minutes increases to 1.18 GBytes, even though the format is the same? The idea of the edit was to reduce the file size while keeping the quality.
Using iMovie instead it is 967 Mbytes at a quality called "High" but only allows me to output at a maximum of 720p. (1080p is greyed out). FCP does not have a control called quality which seems to alter the bits per second as in the one called custom there is a slider for this parameter. "High" seems equivalent to 12 Mbps based on the expected file size. Can anyone explain what this does? I thought resolution and frames per second would determine the bps and subsequent file size.
