Curios, anything else to speed up render times?

So these are my computer specs,
Windows 10 64 Bit
Intel i7 4790k quad core @ 4.36Ghz
16 GB RAM
Nvida GeForce GTX 1070 (8GB DDR5 256 bit) Video Card
250 GB SSD + 1TB 7,200 rpm
Videostudio Ultimate x8.5.

I have seen mixed feelings if a video card would help render times. I purchased a new videocard anyway since mine was extremely out dated anyway. What is the next things to do to make things go faster? RAM never goes past 8gb used, even with 16gb installed, and the computer doesnt seem like its being pushed at all. It seems like you can have the best home computer money can buy, but maybe the program is holding everything back? Switching from SSD to HD hard drives seems to do very little to nothing as far as I can see.

Looking at i7 processor usage during rendering, it stays between 15% - 30%. (2% - 3% @ idle)
RAM is about 5-6gb normally, once I've seen 8 gb. (602 mb when computer is first turned on)
Video card RAM is 1.5 - 2.5 gb, with a GPU load between 15% - 30 % (2% @ idle)
Hard drive @ 0% - 18% (SSD or HD, doesnt matter)

Render times are very variable and your pc is as fast as it can be, IMHO. Here some items that increase render times: filters (some more than others like Mercalli, denoise), bit rates, frames per second, source videos different than project, resolution changes, edits, overlay videos, pan and zoom, transitions, etc.

So, would you say, rendering a video with no filters has nothing to do with your computer but rendering a video with filters do? Or better yet, rendering times are the limitation of the software (Videostudio) and not the computer?

What is fast render? How complex is the project?
On my humble system It takes ~90 min to render, 90 min project of trimmed raw HD mts with few titles and transitions, into 720 WMV file for YouTube . Uploading that to YouTube takes ~300min.

Fine with me. I don't sit and watch the paint dry.

By faster I would mean, taking your example, 45 min to render a 90 min project. What I am doing with my projects, I would take 3-5 min worth of 4k 100mb footage with a crop filter and the ColorFast color filter, and it will take about 4 hours to render to 1080 29.97 fps.

I have just over 4 hours of footage to render out. That's why I ask. I don't have a deadline but the faster this gets done, the faster other people can get these blu rays I'm trying to get them. At the current rate, I calculated it out to about 8 days of none stop rendering. That's why I ask if maybe someone knows about a setting in the program, or computer or anything that maybe able to cut down on time, that's all. For the average person or short video, like you have, it would be ok, I guess. I'm just an impatient person, so that doesn't help either.

I am currently rendering another video clip. Here is what I see currently with the project 9% complete.

Video card memory is @ 713 mb used out of 8gb
Video card load is between 0-4%
CPU processor @ 16 - 23%
Computer RAM @ 4.4gb used out of 16gb availible
Hard drive usage @ 0 - 2% (usually at 0% for 5 sec then a quick 2% usage for 1-2 sec)

Yes, I'd agree with this. Rendering simple edited video clips with no filters in the same format or reduced resolution format should be as fast as the program could do. You could do a test on a short one to see the fastest performance. Complex edited videos that have mixed format video clips with lots of filters rendered to a different format will take the longest and I don't think any upgrade to your pc will make much impact to the times.

Thanks for the reply aljimenez. I was really hoping this wasn't the case, but I guess it's something I'll have to live with.

rob, your culprit is the colorfast filter on 4K video
Just make this tests, remove it and time the render, than add other CC filter instead and render again.
Well?

asik1, the ColorFast filter did impact render times greatly. Is there anything else I can do to adjust color without such a long impact?

Have you looked in the FX library? I think there are ~20 various FX's for some sort of CC.
