I'm shooting with a Hi8 sony. When shooting in the special 16:9 mode, what is the proper capture settings and rendering setting to assure that the final movie is in true 16:9 aspect ratio and the people do not look too short & fat or too tall & skinny?
Hi8 and even D8 don't have lenses or CCD to accomodate both 4:3 and 16:9.
16:9 mode is more often than I'd rather say, a quasi 16:9. You get fewer lines than you do in the 4:3 mode, so it is in fact a crop.
So expecting Vegas to detect this, especially from a Hi8 source, becomes superfluous.
It won't even save tape space.
The only gain is that on some consumer/prosumer cameras you seem to get a slightly larger picture in 16:9 mode to that of 4:3. Folk have assumed that the steady-shot circuit is letting more width of the horizontal get squeezed into the "720" (Hi8!) space.
Where the 16:9 mode is a rip-off. I'd recommend doing this same rip-off in post.
The closest to 16:9 on a 4:3 CCD/lens is to bolt on an anamorphic lens. The cost of these is so great that you might just get yourself a 3CCD 4:3 pro camera.
The 16:9 story hasn't panned out. Yet folk are wanting HD and 24p already.
Consider putting a label on your target formats saying "Best viewed on a 4:3 display, or a 16:9 in 4:3 mode" or add your own jumpback borders to your 4:3 to make it 16:9 so that they can be selectively shown or hidden on depending on the users TV.
14:9 protected is a good aspect ratio to go somewhere in between. You need to think a bit harder to accomodate this in Vegas and end up with representative ARs.
In general I agree with your post, which is in agreement with the article, Shooting Widescreen on DV, but I have a couple of comments:
"The only gain is that on some consumer/prosumer cameras you seem to get a slightly larger picture in 16:9 mode to that of 4:3. Folk have assumed that the steady-shot circuit is letting more width of the horizontal get squeezed into the "720" (Hi8!) space."
I don't know if this also applies to Hi8, but for DV there is a slight increase in vertical resolution from using the camcorder's 16:9 mode, at least according to Ben Syverson:
"The closest to 16:9 on a 4:3 CCD/lens is to bolt on an anamorphic lens. The cost of these is so great that you might just get yourself a 3CCD 4:3 pro camera."
A less expensive approach is to screw on an anamorphic adapter to your existing lens. My Sony DCR-TRV510, like many Sonys, has a 37mm filter thread, into which I currently have screwed a Sony .6X wideangle adapter. It stays there most of the time, not just to protect my taking lens, but because I almost always want the wideangle capability and I can't handhold the long end of my zoom ratio anyway.
Century Optics makes a series of anamorphic widescreen adapters for many camcorders. The ones for relatively small diameter lenses like my 37mm threads cost "only" $395, which is comfortably less than buying a 3-CCD pro camera. OpTex also makes anamorphic adapters, but they apparently don't come in a 37mm version.
Of course I do want to upgrade my consumer camcorder to a pro camera when I can afford to, but in the meantime I plan to go with what I can afford in the near term, namely the $395 Century Optics anamorphic add-on.
In case people are interested in the prices of Century Optics add-ons for other models of camcorders, here is a current PDF price list for Century Optics products. The model for my camcorder, DS-1609-37, is listed on page 5. Models for larger camcorders cost more, typically $895.
