Issue with speed? Not sure..
Hey everyone. I’m not sure if this is the correct place to put this, and if not, I apologize.
I am a bit concerned because I JUST purchased my brand new Mac Pro. (Literally, it was just set up two days ago). I am concerned because it still took me 10 minutes to render a 4 minute, medium quality .wmv clip on Sony Vegas via Bootcamp on Windows 7 and I’m not sure why, seeing as my computer is new and whatnot.
These are the specs:
Two 2.4GHz Quad-Core Intel Xeon “Westmere” processors (Although this is what it says when I go to Computer > System Properties in Windows: Intel Xeon CPU @ 2.53 GHz and I’m not sure what that means.)
It has two 1 TB Harddrives (one is partitioned for Windows via Bootcamp)
And it has 16GB of RAM (which is being utilized according to my system properties on Windows).
And I’m running the 64-bit Windows 7 Home Premium.
This is the same amount of time it took my old laptop to render to same footage and it was significantly less equipped. Please let me know if you need more info or have any ideas about what the issue could be..
Thank you!

That does seem rediculously high for a machine like that. I’ve never ran windows on a Mac before though. Are you adding alot of effects?
Some effects add tons of time to a render. I tried Boris Continuum noise reduction on a 12 minute SD video last night with a 3.4 dual core laptop, Windows 7 64 bit, and it took several hours. -
Actually, no. The projects I’ve been working on this last hour or so had absolutely no effects at all, in fact. Now it really does seem incredibly strange ; I hadn’t thought about the fact that I’m not even using affects.
Is all the of CPU power being utilized? And if not, how do I fix it so that it is? Because as far as I can tell, that’s really the only thing that can be holding it up.. Or, could it be the fact that I’m using a 32-bit Version of Vegas 8 while running a 64 version of Windows 7? I’m not sure if that would affect the rendering speed, though..

32 bit Vegas only sees 2 gig of ram but rendering is CPU only. Start a render, then open your Windows task manager with cntl, alt and del keys, selecting task manager and click the tab that allows you to see all your CPU usage. My i7 PC used all 8 by default, but your on a Mac so I don’t know. That’s one way for you to tell if Vegas rendering is using all your CPUs.
-
It says “0” and “00” in the CPU column for vegas. Now I am just confused.
Please help if you can! 🙁

I apologize for my last reply, I apparently didn’t understand what you were asking. Sorry about that.
While rendering a project with very minimal effects (and I mean ONLY using fade to blacks and crossfades) my CPU is between 65 – 80. -
If you are using any FX that are single threaded, it doesn’t matter that you have 8 cores… only one will be used which will reduce that massive machine down to the equivalent of your laptop. I realize that this isn’t your problem, but it’s just important to point out that not all FX can take advantage of all cores (and before you ask… no, I know know which FX are single threaded. 😉 I believe that all of the built-in Sony FX are multi-threaded but that some 3rd party FX may be single threaded)
Having said that, my QuadCore takes forever to render to WMV which is one reason I never use the format. Sometimes it’s the codec that is slowing things down. Try rendering to Sony AVC and see if you get faster renders.

Thanks for that. I’m not using any 3rd party affects, however, the format you mentioned is MUCH faster. 🙂
Would you happen to know why, when I render into AVI format, little tiny lines appear around images as they move on the clip? I’d love to render in that format but I can’t figure out how to fix the lines issue.
Thanks in advance.

They are probably interlace lines which are required for proper playback on a TV. If you are not rendering for TV (or DVD) you can render progressive using Field Order: None (progressive scan).

Oh, okay, thanks! 🙂
Another issue I seem to having is that when I render a video, in the preview screen, it looks like it’s flickering. I get these lines across it for only a second, but it keeps happening throughout the clip. I was hoping that it wouldn’t show up in the rendered product, but it definitely does. I don’t know what causes it or how to fix it. It happens when I render in all three different formats we’ve mentioned here (the sony one, wmv and avi.)

If you see flickering when editing DivX or Xvid file formats, it’s because Vegas does not support editing DivX or Xvid. Flickering and blockiness in the video are two symptoms of this.
