Tried out the Z1 - questions Can't Post

Hey, I was able to rent a Z1 for a day ... unfortunately the rental unit did not come with a manual so I was sort of figuring it out on the fly.

Questions for you Z1 veterans:

I was shooting in HDV. I then connected an S-video cable from the camera's S-video output to an HDTV with an S-video input ... I wasn't impressed by the picture. It didn't blow me away like most HD programming I've seen, in fact it looked like regular DV footage. I tried the a/v cable supplied with the camera, and the same result. I didn't try the component video out because the TV did not have component in available.

I'm guessing I didn't have some setting correct. I realized afterward that in the "In/Out Rec" menu settings, the a/v to DV OUT setting was ON. Could this be the reason why the footage looked like mediocre DV?

Second question. I hooked up the camera to my editing computer via firewire, and my intent was to downconvert the HDV footage to DV. So in the menu I set the "I-link Convert" to ON, and the Downcovert setting to SQUEEZE. Were these the proper settings for downconverting HDV footage to DV? Was there any other settings I should have been aware of?

Thanks.

Hi David! Welcome to HD, I'm sure it will get going better for you. I can answer your question about viewing
the picture. You cannot get HD resolution via S-video or an AV cable! You must use "component video". This is
the only analog interface which carries a high bandwidth signal to encode HD.
For a consumer TV, there is also the DVI digital interface which can carry HD. You must
use one of these two.
If the TV doesn't have it, then you need a new TV!! :-(
I think all flatpanels today have one or both of them.

I don't know about this camera and downloading, but I would strongly recommend NOT using
the camera's converter to change HD to DV. Rather capture the HD and decide for yourself
what tools you like best to do this conversion. After all, if the camera messes it up,
you have lost the material.
I like and would strongly recommend tmpgenc for HD to DV conversion. I can tell you
more about this if you like.

Hope this is helpful,
Rich

Thanks for that info, Rich. I will try to find a component input next time!

That's because it isn't the same. You may be disappointed to find out that you are comparing two different animals. HDV and HD that is done for programs that have multi-million dollar budgets and use true HD cameras that cost over $100,000 each, are really two different worlds.

Re: [John K.] Tried out the Z1 - questions [In reply to] Can't Post

I have to ask this question: How do you define "true HD cameras"? It would be almost like saying a 1/3 inch DV camera is not true DV and the 2/3 inch camera is true DV.

Methinks you may not undertand the definition of HD. If I understand it correctly, HDV cameras are true HD. HDV includes a specific designation that a number of companies are using that defines the medium by which it is recorded. By definition, HDV is copied to tape at 25 Mbits/sec, same as DV, but not some reduced resolution. Otherwise, it is true HD and you will find no literature or definition to the contrary.

Yes, there are differences between the quality of both color space from 4:4:4 at the high end to something less, but 1080i60 on an HDV camera CAN be nearly indistinguishable from one of those $100K cameras. If you check, you will see that a number of Sony HDC-950 owners also have Z1Us for back up and for places where the large $100K camera won't fit.

I have used the Z1U for several months and I also used one connected to a $40K Sony monitor. If you compared this picture to one from the Sony HDCAM (and there was little movement and the lighting was good), I think you would have an equally difficult time telling the difference.

It's a deficiency in terminology, Tom. Technically, you're right. HDV *is* "HD" within the outlines of the standard. But there is a difference between a $6,000 HDV camcorder and a $90,000 HD camera, and there isn't a really good one word term to describe the difference.

As for your opinion that there is little to distinguish the product of the two devices visually...well, under ideal conditions maybe you are right. But if somebody offered me my choice (and whipped out their checkbook), I know which one I'd pick. Smile

(Or maybe not. I don't think I could afford the matte box for the big camera! Wink)

Well put, Doug

Perhaps the better terms should be "high-end HD" and then something else. Gosh, I guess this doesn't even work! Perhaps we'll soon have the same problem with 1080p or even 2K cameras when these become mainstream . . .

I don't normally advertise "the competition", but Creative COW has just posted an article by Tim Kolb that is exactly on topic. Try: http://www.creativecow.net/...hd_primer/index.html
