Rumor has it premiere 6.5 will export projects to firewire, does anyone know if that works for recording to a miniDV camera or an external dvd recorder with firewire input?

Premiere has allowed you to Render a preview which outputs to firewire for a long time....

I'm not sure what the perceived difference is with this version.

I purchased 6.5

The biggest differences between 6.0 and 6.5 are a MUCH improved title maker, a "real time preview", and an included MPEG export plugin. The latter is being billed as an improvement to make dvd authoring easier.

The "Real time preview" function is perhaps what you're wondering about? This function essentially allows you to (without rendering at all) play through your edit from head to tail and see something on the screen. It essentially spews out a reduced quality "preview" of the content, so you can get a sense of what effects and layering will look like, without having to render. For simple multiple layers with combination, this is a nice feature, because you don't have to render out the whole thing to get a sense of pacing. For more complicated effects (or in my case I was doing color correction, multiple layers and resizing) the result was a really low quality preview, and still a jerky stuttering of what was going on. This new preview mode does not apply to the DV output.

So, I'm still not sure what your initial question meant, because "exporting to firewire" is one of the basic functions the program has supported for awhile.

yes, you're correct, apparently 6.0 already has the "print to video" function. Duh. Thanks. =]

Whats new is that you can now see your work via DV out in realtime as you mess with your project in Premiere. eg even as you scrub back/forth on the timeline you should get that output through firewire. Ive not had the chance to try it myself, but thats whats new anyway.

So I dont understand why Killingfrenzy you say this mode does not apply to Firewire/DV?

Example:

Premiere 6.0
Capture 2 DV files

If you move them about on the timeline and just chop them up but don't in any way overlap them, you can hit "play" on the timeline and DV will spew out of your firewire port to a recording device.

If you alter them in any way (by applying an effect) or use a transition, or overlay one on top of the other as a transparency it will just show an "x" on the DV output for the unrendered region. If you render a preview, it will output DV for those portions as well.
Some types of cropping, speed of playback changes and other effects would often show in the Computer preview monitor (with an "x" over them if unrendered) while the DV output would be black with an "x." Transitions would just show the video running with the "x" over it, and then a cut at the end of the clip, instead of actually showing the transition.

Premiere 6.5
Capture 2 DV files

Everything above applies EXACTLY the same. BUT, there is now an additional option to do what I guess you could call sort of an instant gratification preview. This mode will always show you something in the Computer preview monitor. If the effects are minor, it runs real time, and quality stays clean. If the effects are heavy (say you put a lens effect on) then the program scales the frame rate playback and quality of rendering so that it keeps moving along. The result is that audio is playing back at a realtime rate, but video is scaling its quality of output to keep up and do a realtime preview (sort of like a variable bitrate encode). This has absolutely nothing to do with the DV function, it only effects the preview on the computer monitor.

So, as far as DV is concerned, there's no difference between 6.0 and 6.5
The new "realtime preview" mode applies exclusively to the computer monitor output, not the DV.

I guess I haven't really played with earlier versions that much, so perhaps 5.0 or something doesn't do DV output on a rendered preview?

Cards such as the Pinnacle DV500 and ProOne offer realtime rendering features. I had a DV500 (before it refused to work with my desktop config) and you could do a set of basic effects and transitions without any rendering, and output to DV. It was nice when it worked, but my experience with the DV500 was that it didn't play well with other devices on my system. It was also a pain in the ass, because back then Pinnacle was using a custom DV codec. Not very convenient to have non-standard DV files. I think the Matrox cards are the same way. A digression, but these cards offer something that I would call a true "real time" preview with no quality sacrifice and full DV output, as opposed to the new Premiere function which just means a variable bitrate/quality preview with time set to a constant and only showing on the computer monitor.

Because he has used the program where you've only read the spec!

the realtime preview is to screen only - it doesn't go out of a firewire port nor out of an mjpeg port its just to screen - funnily enough adobe don't publicise this too much
