Hi, I need some help/advise
To begin, For the past year and a half I have been struggling with incredibly slow rendering speeds using sony vegas movie studio HD Platinum 10. I was taking me on average 3-4 hours to render 15 minutes of 640x480 video, 6-12+ hours to render 15 minutes of 1280x720 video, and not even conceivable to render 1080i it would take so long. At the time I was using a lap top, a top of the line lap top mind you, with 4G Ram, good graphics card, and lots of free space. I was rendering from Sony AVCHD to wmv in every case. But I did try the other formats and it will made no difference time wise. Each video contained only 1 audio and video track, and only effects were contrast and sharpen, and no changes in opacity.
Conceding that it may have been that I was using a laptop I purchased a brand new desktop, that SHOULD in theory have been excellent for rending videos.
My new computer has the following Stats
Dell XPS 8300
16 GB DDR3 SDRAM, 1333MHZ 4x4GB
Windows 7 64 bit
Intel(R) Core i7 2600CPOU @ 3.40 GHZ 8MB Cache
NVIDIA Geforce GT530
2TB Serial ATA 2 Hard Drive 7200 RPM
currently, I have 1.73 TB free of 1.80
Compared to my old computer, my rendering speeds have increased - good - but please keep reading...
The first thing I did when I set up my computer was install Vegas, and Sony PMB (I use a Sony HDR XR550V handycam to shoot with and PMB is the only software I have to transfer the files to my comp)
I began editing and rendering some videos I have been sitting on (directly from my external hard drive)
In all cases assume the original file format is AVCHD rendering to 1080 wmv 1video and 1 audio track, sharpen and contrast effects; unless stated otherwise. (it actually makes no difference, because I also used video from a flipcam - shot in mpeg I believe - and the rendering speeds are exactly the same)
At first it was rendering 1 minute of video in about 1 minute, but then a couple days later the rendering speeds started to increase... I had installed a couple of programs (photoshop CS5, autocad, and revit architecture, and windows did its typical automatic updates which I have now disabled.) My rendering speeds went from about 1 minute to 3-6 minutes per minute... I thought it might be the programs or automatic updates that did something so I did a system restore, which did NOTHING but cause me to have to re-install all of my programs again...
Now, it is taking me 18-20 minutes to render 1 minute of video... Really makes NO difference what output format it is in, wmv. mpeg, doesnt matter, but wmv seems to be the fastest.
Currently I am trying to render a 10 minute clip and so far in total it says it will take over 2 hours, but it increases as time goes by and is only halfway done so far...
I have taken the exact same video (this time with no effects) and rendered in in Windows Movie Maker MUCH faster. It takes about 30 seconds for 1 minute of 1920x1080 HD or 15-20 seconds for 640x480. Unfortunately WMM sucks for editing, they have no audiotrack to look at, etc. and I am used to using Vegas.
I thought it may have been my copy of vegas 10, and was informed that even though my comp is 64 bit vegas ten only works on 32bit so I installed the trial version of vegas 11. It made zero difference, infact my rendering times increased slightly. So then I continued to use Vegas 10 instead.
Per a recommendation, I turned off my windows indexing, as well as background Mcafee and restarted my comp - that made no difference.
I tried rendering with CPU or GPU preference and neither made any noticeable difference.
I tried rendering in every format available, and they are all similar speeds comparatively.
Looking at my computer system, is this normal rendering speed for Vegas?? It seems incredibly slow to me. What if I want/need to render a 1 or 2 or 3 hour long video, it will take me a week! or longer if I want more than one video / audio track and some more intensive effects!!!!!! Is this normal!!??
How fast are your rendering speeds comparatively, and how does your computer system compare to mine??
I have contacted Sony Vegas Tech Support a week ago and they still have no responded.
I dont understand what the problem is here, I think I have a good computer and should have much faster rendering speeds with Vegas... Does anyone know something that might be wrong??
Please help!
