Rendering seems to be taking a long time?

So I have a decent rig, 5820k OC'd to 4.4ghz and GTX980 and 16gb mem.

I'm using Sony Vegas 13, utilizing Cuda, using the "internet 1080p" template but dropped max bitrate to 10000 and average of 8000.

Of course content will make it vary depending on the content being rendered but as an average example a 5minute video will take 6-7 minutes to render.

Doesn't sound like much but I'm currently wanting to render 32 hours of footage compressed to around 7hours, and then again down to about 1.3-1.5ish.

Might be right, I know nothing about video editing. I thought this rig would have been better that 1:1 on runtime vs render time though...

I don't use vegas, but try turning down the quaily(also sometimes written as speed). Also try turning off 2 pass if its on. Also unless you need a codec like h264, consider using something like cineform or prores, or dnxhr as they take about 1/3 the time to encode with the same quailty.

A decent encode takes time. When I set my settings high in handbrake, I can render as low at 5 FPS (but I only do short videos, so a slow/high quality encode doesn't take ages).

To the OP. I use Sony Vegas also and it does not use CUDA, except with the older GTX 200, GTX 400 and GTX 500 series of video cards. AND only when you use the MainConcept AVC encoder. None of the newer GTX 600, 700 or 900 series video cards will use CUDA. The reason is, MainConcept hardcoded the list of cards that will use CUDA and the MainConcept AVE encoder has not been update since. Sony really needs to update this information on their website.

Sony Vegas and Sony Movie Studio uses OpenCL for both timeline playback and rendering. While NVidia does offer OpenCL, implemented well. Sony Vegas and Movie Studio really perform the best when using an AMD video card. Now, if you are running Adobe Premiere Pro, then the GTX-980 would be the preferred video card. But, with Sony Vegas one of the AMD R9 video card are the preferred video cards.

Anyhow, you can read more about this in this article http://www.studio1productions.com/Articles/SonyVideoCards.htm
