The ongoing discussion on the 24p versus 24f and on the 720 versus 1080 lines is interesting in the sense that the PAL version of XL2 creates already 576 vertical lines in the 25p mode, if vertical detail is set to normal. Such an image is amazingly sharp for a SD camera. (Maybe we who have the PAL version should post some our best footages to give to the NTSC land people an idea of the 25p image.)
The difference between 720 and 576 is not that remarkable, and thus, it is understandable that Canon went straight to HDV2 and 1080 lines although some people seem not to be happy about that. I wonder, if the XL2 25p image is interpolated to 720 lines, whether the difference between the SD and 720 25p HDV signal is that big -in another words, is the difference worth of an investment?
If I understood it right, the difference between the XL1 25f mode and the XL2 25p mode is that in the XL1 25f mode the number of lines was reduced (by 100) to avoid flickering. In XL2, the vertical detail is included in the menu, and one may choose whether there is the reduction or not. Whatever is the case, the difference in sharpness between XL1 and XL2 is easily observable. (Of course, the lens and other facts matter)
Now, when it comes to XL H1, does anybody know, does Canon give a new meaning to the f-mode, or has it the same meaning as in XL1? Making any judgements from the footages available so far is rather difficult, for there is hardly any device available (here in the PAL land) from which the footages could be viewed in full resolution. All HD ready TV's marketed seem to have ony 720 lines, and have neither seen yet ordinary wide screen computer display which had 1900 horizontal pixels.
