sony vegas 10 render time

I have 1hour, 25 minutes of video on the time line. I am rendereing as mpeg2 NTSC widescreen. It is going to take 9 hours to render. Can this be right, what am I doing wrong. I have a fast dual core computer.

Re: sony vegas 10 render time

That really depends on several factors. But, yes, it can.

How to get long rendering times:
*Start with footage on the timeline that requires lots of processor cycles to decode, AVCHD for example.
*Nudge the opacity slide in track headers off 100%. Easy to do when you're mousing around.
*Apply filters that take lots of processor cycles to render. E.g., Magic Bullet, but there are many.
*Use "Best" rendering quality. This is highly recommended on HD to SD renders, but it does take more time. "Good" is fine for renders with no resizing.
*Don't restart your computer before the render, even if it's been on for days.
*Run lots of resource-hungry applications while you're rendering.
*Have a virus/spambot using lots of resources.
*Sorry, a fast Core2Duo is getting long in the tooth for the heavy lifting that video rendering requires - it really doesn't cut it for AVCHD, not bad for DV or HDV with V10.

So, yeah, on a dual core with MB or starting with AVCHD, you betcha' that render takes a while.

Seth, all the others seem obvious, but this one has me wondering.
Till now, if doing a long render, I have always restarted to clean up the process list and clear caches.
Could you elaborate on why?
cheers

Re: sony vegas 10 render time

Hi Bill

That's actually about right!! On my old DuoCore 2.2GHZ renders were taking me around 8X realtime so 1 and a bit hours would equate to 9 hours!!

I have an i7 2600 with 8GB ram now and it renders to SD in around 1/3rd realtime or less so the same clip should render in around 20 minutes on an i7... the difference will amaze you!!!

In addition the PC may be running too hot simply through lack of maintenance. You can check the temperature using the free Core Temp:

Core Temp

Just blowing out the dust and cleaning the fans can help a lot.

How? I went to your link, downloaded it, installed it and could not find it anywhere. Not on my desktop, not in the start menu. So I unistalled it.

Re: sony vegas 10 render time

Adam, I believe Core temp runs as part of All CPU Meter, a Windows gadget.
It may not show without the other program.
When working it is a handy tool.

Re: sony vegas 10 render time

Well, I have since remembered that I have the CPUID HWMonitor, which gives much more information about my system, such as the temperature of every hard drive as well as of the GPU in addition to every core of the CPU. So, it turns out Iím covered as far as hardware monitoring goes after all.

I'm being too cute with my wording. "Not restarting" is on the list of things to get long render times.

Re: sony vegas 10 render time

wow... good advice Seth, thx! but i gotta rewrite it or i'm gonna go crazy...


TIPS TO MINIMIZE RENDER TIME IN VEGAS - Seth Bloombaum
  • AVCHD footage on your Timeline will use lots of processor cycles. Consider using intermediates.
  • Check that the Opacity slider for each Track is set to 100%. Anything less can greatly increase render times. (happened to me recently)
  • Plugins can significantly add to render-time as some filters use a LOT of processor cycles: Magic Bullet, BCC, etc.
  • Use "Best" when scaling images or footage (animated photo pans, HD to SD renders, etc).
  • Use "Good" when no scaling/resizing is being done.
  • Restart your computer before rendering.
  • Turn off any applications or background activities that are resource-hungry (some virus/spambots are bad for this for instance)
  • A Core2Duo computer isn't bad for DV/HDV (Vegas10)... for AVCHD, consider purchasing a newer system.

(did i get all them right? ...think i did but not sure lol...)

Re: sony vegas 10 render time

Well, my list method seemed good at the time... but, Rob, I think your version is going to be more helpful.

I suppose we should add that there have been rather dramatic improvements for editing new camera codecs in various versions of Vegas Pro. It would run something like this:

DV - V4
HDV - V7
AVCHD - V? (I'm not sure if this was V9, 10, or 11. Somebody here knows.)
Canon dSLR MOV - V11
