Oops... did I goof?

When working on a project I frequent set up multiple video tracks,just to shuffle things around, then unused ones get deleted before rendering.

Well, I started to render a long project that Vegas says it going to take about 12 hours and I forgot to delete several empty tracks. Anyone confirm it adds to or DOESN'T effect the rendering time? In other words do totally emply tracks left in a project effect rendering time or not?

I just did two 10 second renders to test this, as I've not checked this since Vegas 3.
No difference in time if the track has nothing on it, but I did get a 4 second diff if there was an empty 3D track. On the other hand, it could also have been a process running in the background slowing the render. I wasn't looking for hard, fast results. You're more than likely OK.

BillyBoy, I don't think it does. I have got to be one of the most inefficient editors I know and many of my projects will have 20+ layers. From what I've been able to tell it still only takes as long as the elements being used would dictate. I was going to say " visible " , but in theory if you had a blank text layer across the vid I'm certain it would still add to the time.

I'd also like to add that when I've got long renders, I break them up into manageable snips - like anywhere from 30 seconds to a minute or so, depending on the complexity of the selected area.

Generally, in fact, I am making these saved prerenders, as I go along with the edit. I keep all of these pre-renders on the top track, so I can see what's been rendered. A lot of my stuff is effect heavy, and these pre-renders are necessary to "feel" the real-time flow of the video. BTW, I have a special "Render to New Track" setting which is the one I use for these pre-renders. It's high quality with NO SOUND. That way I'm just rendering the video. You can create it, and it will always be there for you, in the drop down box.

Then, I'll actually make a "Final" copy of the pre-renders - just to have a single uncut file, for reproducing as MPEG, QT, Real, etc. This one I make with fully mixed sound track. In other words, it is The Show. If I make a further revision, I throw this one away, and re-do another full render. Since you are only copying all the pre-rendered video, this final render goes very quickly.

The advantage (and it's HUGE) is that wheny you make a teeny little change, you only have to re-render that area of the edit, saving huge amounts of time and disc space.

Is this clear?? I'll write more, if necessary.
