long rendering time
I am in major trouble with rendering times. I have two videos
back to back and the first one had 23hrs plus rendering time.
I am trying to make a master track so that I can render an mp4 and also wmv from . Something is wrong and I KNOW it is how I am doing this.
I have three cameras
4 audio tracks
I made all of the cuts then went in and did the chroma key color
correction and also audio. Is it possible that I have to many
edits…effects etc. that would cause such a long render time.
I have a fast computer. I am two weeks behind. I have posted before
and did what was suggested and still having trouble. -

The Chroma Key is very render intensive. It is really doing a lot of work to create the new frames. There’s not a whole lot you can do. Make sure that you haven’t used too many redundant FX. For example make sure that you have applied Color Curves to the media, the event, and the track. If that’s the case, remove all but one and adjust accordingly.

Thanks John. I have been having a problem with a yellow
cast and green screen is way to bright subject is not lit enough.
So Your advice about getting rid of the yellow has helped. I still
have way to much color correcting. If the lights were right
I wouldn’t have trouble with a lot of this. -

What are your PC system specs in terms of CPU, RAM, operating system and Vegas version? I couldn’t find your system specs in your earlier post as suggested. 23 hours is a long render time. What format are you trying to render from and to?
I regularly edit and render multi-cam HDV shoots, and 1.5 hours of time line footage with colour correction and multiple effects seldom takes longer than 2 hours to render, even with 2 pass variable bit rendering enabled.
The only time I have seen such long renders is in DVDA when I had to create a blu-ray ISO image from HDV renders (that took 23 hours). The resultant ISO contained 4+ hours of HDV video. DVDA is a single threaded app, whereas Vegas is multi-core aware.

Hi Nigel Here is what I have
Dell Studio XPS7100
AMD Phenom X6 1045T Processor 2.70 ghz
Ram 8gb
64bit Windows Pro (Maybe I should buy a better computer.)
Vegas 10
BCC 7I am wondering if my render settings are all wrong.
(render to new track) I then render a mp4 and wmv for
the web and also a DVD. Last night I rendered again
and didn’t color correct on cam thought it might cut
down on the time. I could send screen shots with my settings.
Thanks

That’s a pretty powerful system and should be more than adequate for the job. Do you have more than 1 hard drive in the system? The Dell system also has an ATI video card. You might want to consider replacing that with an NVidis GTX 480 or GTX 570 card as Vegas takes advantage of the CUDA cores on the card during certain renders.
What is your source footage, project settings and render settings? Screen shots will help.
By way of comparison, how long does it take to render unedited footage of a similar duration? Are you able to run a test and post your results?
If you are running anti-virus software, disable it (but don’t forget to re-enable it afterwards).

[Nigel O'Neill] “You might want to consider replacing that with an NVidis GTX 480 or GTX 570 card as Vegas takes advantage of the CUDA cores on the card during certain renders.”
Sony has announced that Vegas Pro 10d will take advantage of OpenCL so there is no longer any need to have an NVIDIA card. ATI cards will work just as good once 10d arrives.
