Slow Rendering Speeds – Advice Please
I am currently at a loss because the rendering speeds for SV Platinum HD 10 are so slow for me. If anyone can offer input as to why my speeds might be slow, and if you know anyway to fix it please advise me.
For all of the following assume:1video track and 1 audio track. The only effects are contrast and sharpen. No changes in opacity. Original footage filmed in 1440x1080HD avchd (from sony handycam xr550v ) and rendered as .wmv 1440x1080HD best quality, sharpest picture.
For the past year and a half I have struggled using sony vegas to edit small video clips, it was not even concievable to render in 1080i the speeds are so slow. It would take me 45 minutes to 1 hour to render 1 minute of 1280x720HD wmvvideo. 25-35 minutes to render 1 minute of 640x480sd video. I did NOT have a horrible computer. It had 4 RAM with a good graphics card and lots of free space. using a Windows Movie Maker compatible file, I could render a 1 minute 1080 HD video in WMM but the exact same clip – no effects – would take the above times.
Unfortunately WMM is not friendly for editing videos IMO
Finally I broke down and got a new computer thinking that maybe my computer was just not up to it. I invested in what I consider a top of the line comp with the following stats
My computer
16 RAM
Windows 7 64 bit
Intel(R) Core i7 2600CPOU @ 3.40 GHZ 8MB Cache
NVIDIA Geforce GT530I have 1.73 TB free of 1.80
I immediately installed Sony PMB and Vegas to test my rendering. Things were looking great it was rendering 1080i footage about a minute per minute (which seemed great to me compared to what I was getting before)
Well I’d say a day or so later I noticed my rendering speeds really slowed down. They seemed to double / triple. I installed a few programs – photoshop CS5, autocad, and revit architecture. I still had 1.72 or 1.80 TB free space.
After a day of WTF is going on here, I decided I would do a system restore – thinking Windows automatic updates may have been the cause.
Well, system restore did nothing but make me have to re-install everything again. I made no difference in my rendering speeds.
I then thought maybe it is my disk (perhaps its corrupted somehow) so I installed the trial version of vegas 11 but NO same times (actually a little longer)
I attempted to render the exact same video with Windows Movie Maker Live and it will render the same video (both no effects) 1 minute of 1080HD in about 35 seconds! 640SD in 15-20 seconds!
Now when I try to render files in vegas it seems like it keeps getting slower (and then jumping up and down depending on what time or day I want to render :/ ) Today it took me 20 minutes to render a 1:45 minute 1080 clip!! the other day it took me 35 minutes to render a 7 minute 1280×720 HD clip. Its jumping between 3-12 minutes for HD rendering, and proportionately slow for every other file type, video size.
IS THERE ANYTHING that anyone can think of as to why this is happening.I would love to here what YOUR rendering speeds are – based on what system you have
If there any settings that vegas automatically?? changes?
Is it possible windows screwed my computer up somehow and maybe I should re-install windows?
I am really at a loss here
Ive contacted sony and have yet to hear back. I really dont believe that with my computer I have now I should have times this slow (be it they are MUCH faster than my old computer) but even that was ridiculous and did not seem right.
Thanks in advance for any help or insight

Try stopping the Windows Indexing Service and disable any anti-virus software running.

Hi Adam
I have a YouTube channel called TemporalParadox1 (specialising in Vegas Movie Studio) where I have uploaded video tutorials showing how to set up a project and render to what ever template you need.
The best template to use to get the fastest rendering times is Sony AVC .mp4.
When you “customise” this template, you can select to use GPU Acceleration or the CPU for Rendering Only.
Try both settings, to find out which performs best on your machine.Windows Media Video (.wmv) encoding is a lot more CPU intensive than using Sony AVC/AAC .mp4.
Remember also that Vegas Movie Studio is only a 32bit program, so even though you now have a 64 bit machine with lots of RAM, this is not all accessible using VMS. This is where Vegas Pro 64 bit makes a big difference.
On your computer setup, I would strongly encourage you to add a 2nd Hard Disc Drive. So one HDD stores your source video files, and the other HDD can store all the projects & videos being created by Vegas. This setup will speed up your processing times, because at the moment you have one HDD reading and writing at the same time. When you have TWO drives, one can be dedicated to reading only and the other to writing only.
My PC Specs:
CPU: Intel i7-2600k @ 4.6 GHz
GPU: Nvidia GTX460
RAM: 16GB Corsair Vengeance
Boot Drive: 120GB Solid State Drive
Storage: 2 x 1TB Hard Disc Drive
Sound Card: Creative Soundblaster X-Fi Titanium -
Thanks for the advice,
I went ahead and did that, unfortunately it didnt make any difference with rendering times! 🙁
I wouldnt be concerned except that I know others who have less powerful computer systems are able to render similar videos way faster than I am; it doesnt make sense to me.

Thanks for the input!
I actually downloaded sony vegas pro 64 bit trial to see if it made any difference and it took slightly longer to render the same clips haha…
The footage I am rendering from is not stored on my computer, it is in an external hardrive (is this similar to what you mean?) but I have tried both ways – having the original footage in an external as well as on my PC
I now tested the customizing CPU or GPU acceleration, I didnt see a noticeable difference between the two options.
I also tested some rendering with Sony AVC mp4 and they took about 25% longer to render than the same clip in wmv
The thing that gets me is I read people say they have 3,4,6 ram, slower processor, etc. (and undoubtedly do not have 98% of their computers ram available) and they are rendering 1080HD video much faster than me. I just do not get it.

I thought you were using Sony Vegas Movie Studio HD Platinum 10?
If I had known that you are now using Pro 11, I probably would not have bothered responding as there is already much information about this new version posted on the COW.
Have you actually tried my suggestion using VMS10 first ?
Bringing Vegas Pro 11 into the equation opens up a new can of worms, which I fear will now add to any confusion. -
I am and have been using vegas 10, I only downloaded the trial version of 11 to test it, in hopes that perhaps my current version was messed up. It performed the same or slower so I have just continued to use 10 since I am not going to buy 11 with it showing any enhanced performance.
My current file I am rendering has 3 video tracks and 1 audio track – cookie cutter and contrast effects. It takes me between 3 and 5 minutes to render 10 seconds of 1080 or 720 HD any file format.
