Sony Vegas speed up rendering

[Nik12345]

Hi!

I would like to upload gaming videos to Youtube but rendering a 30minute video takes me about 15 hours at the moment and I was wondering if you could help me to find better settings?
I'm using Sony Vegas Pro 13.

CPU: Intel core i5-4570 3.20Ghz
Graphic Card: Nvidia Gforce Gtx 760
Memory: 8gb

current settings:
MP4 (AVC/AAC) - Internet HD 1080p
video: 29.970 fps, 1920x1080 Progressive, YUV, 12 Mbps
audio: 192 Kbps, 48,000 Hz, 16 Bit, Stereo, AAC

file size is about 1.5GB, render time is about 15hours.
CPU usage is between 30-50% during render, Memory usage is about 90%.

In order to upload the videos to Youtube the filesize for a 30minute video should not extend 2GB.
Do you have any advice on how to speed up the process?

Thanks

Are you using GPU acceleration with that card? If yes, have you tried rendering without using the GPU acceleration? Are you using the Main Concept encoder or Sony's? Not saying this will help with render times but you may want to consider upgrading the RAM to 16GB for video editing.

Thank you for your answer, yes i've tried rendering with and without GPU and i tried both Main Concept and Sony's encoder but nothing seems to have a significant impact.
Improving my hardware would definitely speed up the process but I'm wondering if it's possible to speed it up just by using a different codec or different settings. 15 hours seems a lot to me for a 30minute video.
The quality doesn't have to be top, but changing it from 1080 to 720 didn't even significantly speed up the rendering, neither did changing the framerate from 30fps to 25fps. Rendering the video with 15fps only took 1/10 of the time but the motions look blurry.

I agree that 15 hours is excessive for a 30 minute video even if it is at full HD.

I wish I could be more helpful but I'm not familiar with the render settings since I don't use Vegas.

I'm not sure how well the GTX 760 works with Sony Vegas 13. I've tried newer AMD and NVIDIA cards with very poor success using Vegas 12, Movie Studio 12 (and 13). Both the R2 290 and GTX 760 cards performed poorly with Vegas. It seems NVIDIA crippled cards after the 500 series as it wants consumers to buy the overpriced and outdated Quadro cards. My GTX 570 renders movies in a fraction of the time it takes my CPU (about 80% faster).
