(ANSWERED) Rendering Question

Hello Group

I'm rendering a music video with some resource demanding fx in it and had a question about rendering time. Please excuse my newness in trying to explain what I'm asking.

I'm still in the scene sequencing stage, and so many of the video track sections run concurrently with other track sections until I make my final decisions on scenes. Even though I only have one video track section viewable at a time, does having multiple tracks overlap like that take more processing power while rendering? Would rendering take less time if I muted the track sections that are not the focus track until I make the final scene decisions and then I'll just cut the scenes out of the tracks I'm not going to use?

If I'm still not clear, here's an example. Track one has video that runs the length of the project. Track two also has video that runs the length of the project. I'm flipping back and forth between track 1 and 2 to decide which I want to use. (Of course, you can only see the video from track one). While I am rendering the project, I am not muting either track. Is that taking more resources to render? Should I be muting the tracks or sections of tracks I don't want to see to make rendering go faster?

Thanks!

I recall reading a discussion about this recently but it may have been an old thread. Some posts in this thread touch on your query https://www.vegascreativesoftware.info/us/forum/possible-explanation-for-some-slow-renders-bug--99410/?page=4#ca609755

You could try doing test renders with say one minute of your timeline to see if there is any difference between muting unwanted tracks, deleting them, or just leaving them hidden by upper tracks..

It shouldn't matter, but, since you're new, you should know that strange things have happened before you got here.

The other nonplaying tracks still are stored in memory, so that "may" be a factor.

As @EricLNZ suggests, who don't you run some tests and let us know what you come up with.

Here's a thread from some years ago started by John Meyer that reported a problem. https://www.vegascreativesoftware.info/us/forum/possible-explanation-for-some-slow-renders-bug--99410/?page=1

As an update, I removed all of the overlapping content in each track and out of about an hour to render previously, it cut down about 12 minutes rendering time. Not a lot, but something.
