720p vs. 1080i Can't Post
Okay, I'm sure somewhere on this forum is an archived post about this topic. Too busy to find it, so I'll just start a fresh one. I'm looking into make the HD dive, and I know I want a true progressive camera. That leaves Panny's HVX200 or JVCs HD110 or 200.

The P2 card system (price and usability) makes it a total no go for event work (in my mind). So, no we're left with JVC. And it seems to almost everything going for it. The form factor is exquisite. Love the ability to interchange lenses. True progressive. Great imagery. The only concern I have is that it's only 720p. So, for those who use JVC, or who just are in the know, answer me this:

1. How does a 960x720 image look on a 1920x1080 TV? Does it feel the screen, and if so, is quality lost? Is there a form of letterboxing? What happens?

2. If the image is upsampled to 1920x1080, how is quality affected.

I hope someone responds.

Thanks,
Ron

The sony v1u is has a real progessive mode I'm understanding...

From what I've seen, 720 upsampled to a 1080 screen still looks good, but is noticable from 1080 on a 1080 screen. Upsampling is upsampling, it will never look that great.

Probably not what you're looking for, but I responded.

Technology. It does wonders if you know how to use it.

Thanks Jerome,

My understanding is the HDTVs can read 720p or 1080i signals, so the upsampling may not be an issue. I'll look at the V1U too. But, in terms of shooting progressive HD, 720p is the only realistic option. Right?

They can read both signals, but if you have a native 1080 screen (1920x1080) sending a 720p signal will be somewhat like sending a 480 signal to a 720 native screen (though not as bad.) The bulk majority of HDTVs in stores are native 720 and NOT 1080. That's one thing that pisses me off about them.

In my understanding, the V1 will record 1080 in progressive scan. IMO, 1080 is the best method... even 1080i downscaled to 720p looks damn good.

Take a look at the Canon XL-H1 too. It doesn't have "true" progressive recording but the 24f mode is reportedly pretty good. Downside is that the ergonomics of the XL-H1 is poor compared to the JVC HDV models, so if you like a shoulder-mounted form factor then JVC may be the way to go. I wouldn't worry too much about the difference between 720p and 1080i/p recording unless you plan to go to film or have customers displays, but then again some customers may start insisting on 1080i/p recording. Hence a good reason to consider the Canon...

Hi,

I'm leaning towards JVC's HD110 or the Sony V1U. I really want 24p. The Canon XL is way out of my price range (isn't that the $9K camera)?

Lots 1080 24p options now...
Sony V1
Canon HV10
Canon XH A1
Canon XH G1

All are good cams. Even though the Canons are not true progressive, it's pretty tough to tell the diff unless you've got analyzing tools.
