720p24
720p24 is sometimes simply referred to as 24p mode, and is considered by some to be
the most flexible frame rate choice because it is possible to transfer to NTSC and PAL as
well as to film. Choose this mode if you plan to transfer your finished video to film, or if
you are trying to emulate a film look on your final video.
Even though the camcorder always records 720p formats at 59.94 fps, most of the
frames are tagged as duplicates and can be removed during capture. As a result,
720p24 on your hard disk has a much lower data rate than other DVCPRO HD formats.
Important: Video transfers using FireWire currently require that 720p24 video actually
be recorded at the NTSC-compatible speed of 23.8 fps.
Pros
• Perfect for video-to-film transfers because of matching frame rates (23.976 fps)
• 60 percent lower data rate than 720p60 because of the lower frame rate
Cons
• Smaller image size than 1920 x 1080 (though still higher resolution than standard
definition video)
• Requires an extra telecine pulldown process when transferring to NTSC
• Requires a frame rate increase process when transferring to PAL
Note: The workflow for capturing, editing, and output of 720p24 is similar to the
Panasonic DVX100 workflow.
