Steve Mullen of Videosystems has a nice breakdown on the particulars of 24p in the HDV format.

On the MPEG cadence that transports 24p: “Through this process, 720p60 is output carrying 24p video. Because JVC uses a standard MPEG-2 feature, some hardware and software were able to support the HD100 immediately…”

“Moreover, some software handled 24p without problems: CineForm’s AspectHD and Sony Vegas 6, for example. Thus, it is clear that if an NLE company had fully implemented MPEG-2 when it introduced HDV support, JVC’s 24p would be automatically supported.”

Zing. How do ya like dem Apple’s?

“JVC’s 24p also is able to be edited as one would film. By dropping the 36 Repeat Flags within each second of HDV and transferring only the 24 remaining frames of 720p HDV video to disk, one has the video equivalent of film.”

Great article, very informative.

We recently posted another Steve Mullen article that deconstructed how Canon potentially does 24p in the HDV standard.
