Why bother rendering?

[daamon]

Hi All,

I've got Premiere Pro 1.5 with DV AVI from my miniDV cam. I get my timeline sorted how I want it and then render - no problems.

Then I either frameserve using the DebugMode Frameserver to my MPEG encoder, or export the timeline out as DV AVI.

Either way, Premiere says it's rendering - again. Why is this if it's been done already?

Cheers.

Before frameserving, you are rendering to what. Premiere "renders" the time line meaning , it renders the effects and or transitions and cuts as a bunch os little temp files in the DV avi format usually saved in the Premiere Render folder. It is not the MPG2 final render you need to make a dvd.

Sorry, I should have also said "I know what rendering does" - i.e. it produces, as you say, a whole load of DV AVI clips in the "Adobe Premiere Pro Preview Files\[project name].PRV" directory.

My question is, if these clips are created, then why bother if, when frameserving or saving to DV AVI, Premiere Pro says "Rendering" while doing either of these? Is it actually rendering a second time? Or is that a misleading message?

Yeah...
Some sort of temporary buffer might be created for smooth feeding to the encoder..
I'm surprised i havent' noticed or paid attention to that little quirck...

I agree, and you have to wonder. I seems to do temporary renders for instance, to be able to preview a nice smooth version of an effect or transition. WHether it actually re renders yet again is a possibility. Other programs like Liquid edition, Avid and even Pinnacle Studio also does that. They create "redered" clips as you are editing which can add up to gigs worth of "rendered" files. I fact you can see the progress of this rendering because the color bar aboe the click that you have edited gradually changes from red to green.

But at the end you will have to render the final contigious AVI or MPG file anyway. I see what you are saysing clearly now and have to agree that is seems redundant.

I've also noticed...When you save out footage back out as .AVI, that unrendered (red lined) areas don't get rendered on the timeline, but get magically rendered on output.. but haven't kept an eye on the Preview folder..

Maybe i'll try it out when i get home..
