Hallo everybody out there!Ths is my first post in this amazing foum :)
I own a hdrz1 and i edit with Sony Vegas pro8.
First question: is it a good workflow to shoot always in HDV than downconvert in SD when requested?
When i downconvert a file HD 16:9 into sd 4:3,will the image get distortion?Will i get a good 4:3 image?
thank you guys and happy to be on board with you
:)

Yes, if you go from HDV 16:9 to 4:3 it will be very distorted.

ouch!So the best workflow that you suggest?Downconvert in 16:9 SD?
And what about if this work will be watched on a 4:3 tv screen?

There are three ways to have the Z1 downconvert to SD: 16x9 letterboxed into a 4x3 image, in other words, with letterboxing, black bars at the top and bottom. Then there is cropping the center 4x3 section out of a 16x9 image, so it cuts off both sides of the 16x9 image but displays full-screen 4x3. Last, there is 16x9 anamorphic which is where it compresses the entire 16x9 image into a 4x3 screen and the playback device expands it back out to 16x9. This is how wide-screen DVDs work.

I have had great success with Vegas and the Z1 and shooting HD will produce good looking DVD's.
Rendering to MPEG-2 is very easy.

Is it better downconvert through the deck(or the z1) or is it better to capture the files in vegas as HDV files,then edit in timeline then render to widescreen 16:9 SD?

If you capture HD images you can get better stills from the footage, have more flexibility.

Otherwise it doesn't matter.

So this is what i'm doing:
connect the camcorder-capture hdv files in hdv project-batch capture using cineform-edit then render to widescreen 16:9 right.

Jeff is it correct?

The problem now appears cause i have to add 4:3 shots in Dv format;somebody told me about plugins or script;what's all about?

p.s:sorry for my english

What you are doing sounds correct.

I don't know about adding 4:3 footage, haven't mixed the two myself. sorry!

I've added 4:3 footage to my 16:9 footage/timeline in vegas, i just cropped the 4:3 into 16:9.
There's a 16:9 preset in the pan & crop list.
Crop to 16:9 then move the crop box up or down to suit, ie correct headroom etc.

Hey Paul and Jeff,thx!
Paul i know that here's a preset to crop in 16:9 but cause of letterboxing(having those lines up and down),i should zoom in the clip despite lost of quality?Or ami wrong?

Lines up and down ? Do you mean the black bars at top and bottom ?
If you select the 16:9 preset when you crop the 4:3 then you won't have any bars top and bottom, you'll get a full screen 16:9.

Have a look at Paul Kellett Channel on Vimeo (http://www.vimeo.com/paulkellett)

this was a wedding i shot with my EX1 (16:9) and another camera which was the 4:3, i cropped the 4:3 into 16:9.
A slight loss in resolution when doing the crop but better than flicking to and from 16;9 and 4:3 on the finished dvd.
