Does anyone know which is better HD or HDV , im looking at a HDV camera and I was thinking a HD camera would be better.
Am I right?
 
It looks like you still have a fair bit of research left to do. HDV is one kind of HD.
 
SAme thing. HDV just means its Mpeg2 based encoding that loosly follows a standard guideline for compatibility. HDV is HD. HD just means a frame size of 1920x1080 interlace or 1280x720 @ 60P. Now within thatt heres some room for interpritation. 720-24p, 1080-24p....etc....

So would you be saying HD is better
 
No. He's saying that HD is a certain resolution, that there are various ways of obtaining it, and HDV is one of them. You don't need to post 3 times.
 
Here's a break down of the differences:

Non-HDV:
HDCAM - Records at 145 Mbps., 3:1:1 color space, 1440x1080 resolution, records Progressive Segmented Frames, not solid progressive.

HDCAM SR - Records at either 440 or 880Mbps, 4:4:4 color space, full 1920x1080 resolution, records solid progressive frames (I believe).

DVCPRO HD - Records at 100Mbps, 4:2:2 color space, 960x720, 1280x1080/60i, or 1440x1080/50i resolution, records solid or interlaced frames. (There is also AVCIntra codecs, but I won't get into them.)

HDV:
HDV - Records 25Mbps, 4:2:0 color space, HDV 720p - 1280x720 or HDV 1080i - 1440×1080, records solid or interlaced frames in a GOP pattern.... meaning frames are dependent on the surrounding frames, so some frames may drop resolution to compensate for other things going on in the frame.



Some people, including myself, don't consider HDV to be True HD (because of the poor color space and file size.), but all the above formats are technically HD. HDV cameras are generally Consumer and Prosumer cameras.... Professional (except for a few; HVX200, ect.) are the only cameras that use HDCAM, HDCAM SR, or DVCPro HD.

without wishing to spiral out into a full out heated debate, HDV is High definition by definition, of course you are correct that the codec is not very professional (eg keying) although it can be done.

But I think with cameras we need to look at the whole package not the individual components, and as such I would say that I'm still a little frustated with 1/3" sensors in general, its great that we can get HD resolution with a great format nowadays, I just wish the market would trickle down enough that 2/3" becomes accessible to Indies (again expensive is a relative thing I'm well aware), I guess we will be waiting a long time though.
 
Also - formats, codecs, and cameras can't be decided on in a total vaccuum.
Alot of this depends on what you're shooting, what you already have, what else you plan on getting, and where you want to be in the foreseeable future.

It's pretty clear from the questions you're asking that you haven't looked into it too deeply just yet. The HD landscape can be a very confusing one when you first step out there. My suggestion would be to take your time and do a lot more research before trying to decide what your next step is camera-wise.
 
By the way - doing some searching on this site (which I HIGHLY recommend you do) - I found these threads that might be of interest to you:

Hopefully that will help clear some of this up for you....then it will confuse you some more... then it will be cleared up again.

HD or HDV?
I think if you let us know the top end of your budget range we can shorten this conversation significantly.
