Hope this clears up the confusion. In HD there are some different flavors. When you her 720P it refers to the vertical resolution and the P stands for progressive. If you have photo shop I suggest you open it up and create a document that is 1280 pixels wide by 720 high. Make the document blue. Now make a document with that is 1920 pixels wide by 1080 high make it red. Now drag the blue layer into the red layers document. What you will see is the difference pixel for pixel in resolution between 1080 and 720. Now lets talk about HDV 1080. Make another document 1440 wide by 1080 high, make it yellow and drag that layer into the red layers document, resort the layers so that the blue layer is at the top level so that you see three colors on your master document. Now you can compare visually the difference between true HD 1080i, HDV 1080i, and 720P. Your probably asking yourself why is the HDV kinda square and the others are in 16 by 9. The answer is HDV is anemographic or non-square pixels; meaning when it gets properly projected on a monitor or TV the image gets stretched to 16 by 9. The same things happen with DV just vertically from 480 to 540 equivalent pixels.

OK so I hope you understand what the difference is between 1080 and 720 now. Lets talk about the I in 1080i versus the P in 720P. If you take a picture with a film still camera and you get your negatives back, you can see one solid picture in every frame, when those pictures are moving on a sprocket past a light bulb at a rate of 24 per second you have motion pictures. One of the negative flaws in film depending how you look at it is a bit of a stutter, this stutter can be increased by the shutter angle but is generally due to the nature of running the camera at 24 progressive frames per second. If you changed the speed of a film camera to 60 frames per second and projected it at 60 frames per second it would look very similar to video as far as the smoothness of subjects moving across the screen. I’m not going to go into how video came to be but I will explain that 1 frame of video is comprised of two fields, these fields are interlaced, the “I” in 1080i. That means that each video frame has two different pictures in it or I should say half of two different pictures. One field is even lines and one field is odd. I think in the end we reject it just because we all go to see movies and that amount of stutter feels better instinctively, and then when we see interlaced video it looks to smooth. One of the issues with why the Sony doesn’t look good in its 24cine mode is because it has three interlaced 1080i CCD’s By its very nature it is interlaced fallowing and interlaced spec, and the conversion process they implement to try and take those two halves of a picture and put them into one solid progressive frame with a 3 2 pull down to take 30 frames per second and put it into 24 just doesn’t work well on the fly. Cannon will have the same prob with the XLH1 but my do a bit better job at it, but anyone who owned an XL2 knows that they didn’t do as good of a job as Panasonic with the DVX100. JVC did a good job because the spec of 720P made it effortless to get a true 24P image.

OK why didn’t they make the HDV spec 1080P, I don’t know? But because Panasonic is not adopting the HDV spec, they should have little problem implementing and already tried and true vericam 1080P into the HVX200.

I got to say that’s the camera to buy but as consumers we are all getting boned by the price tag on those P2 cards. Panasonic is using its clout to take advantage of us because they know or they hope they can, however I can wait to see the angry faces when non technical people find out they can only record 16 minutes of HD at a time having spent 10g’s

Ready to make Money?
Don’t miss the new wave.
High Definition video is here!

If you hadn’t noticed, the wave of Mini DV and DVD is dwindling. Sure it was lucrative in the beginning, but with all the “mom and pop”
competitors springing up you probably realized that the bulk of the money was made in the beginning, when we had the chance to get steady repeat
clients. Now the clients have invested in their own equipment and they’re doing it all themselves.

The steps in creating High Def content are easy.
First you shoot with a High Def camera or an affordable HDV camera like the Sony FX1 or Z1U. Edit in Final Cut Pro HD, Premiere Pro with the
Cineform HDV plugin, or Ulead. Author a DVD with ROM data containing your High Def content and you’re done. Preparing your HD movie for
a standard def DVD takes little effort and the result is a clearer picture that your viewers will appreciate.
