[MacDV] Re: 16:9 vs 4:3

[Kunga]

But HDV (different format MPEG-2 On Tape) is more per hour I think. See 
Sony HDR-FX1 review in March DV magazine pp. 16-21

Apple's new codec changes all of the code to a full set of i-frames on 
the fly to the hard drive then back to MPEG-2 when writing back to tape 
or authoring to DVDSP or iDVD 5 from iMovie HD [5.0.1 (v99)] or 
upcoming Final Cut Express HD (3). Both applications use the same new 
Apple engineered codec to convert MPEG-2 to all i-Frames and back. I 
asked at MacWorld Expo.

I think the HDV format crams more GB per hour on magnetically denser 
HDV tape than does DV shooting on lighter density DV tape (same size 
cassette). But I still don't know the size per hour. Anyone know if I 
am thinking correctly or not?
