Re: New Sony HDV Camera - Under the Christmas tree this year?

[Guy Barwood] "remember though that while there are many problems with interlacing, it is known to provide better results for fast motion. "

The only reason being that you've virtually got twice the framerate if it's interlaced: 60 fields per second vs 30 frames per second.

[Guy Barwood] "My question is if 60i is 120 fields per second (& 50i=100fields/s? "

60i is only 60 fields per second, so still 30 frames per second, but 720p is 60 full frames per second. That's the reason it requires more bandwidth.

[Guy Barwood] "I wouldn't be suprised if 1080i looks sharper, but 720p is better for keying, etc "

Yeah, 720p should be better for keying due to the way the color signal is more spread out vertically in 1080i. They're both 4:2:0, but progressive makes quite a resolution difference.
