Slow Video Render? incl. New & Old PC Specs So I've been recording gameplay &amp; posting it on YouTube for a few years now. Primarily using Sony Vegas as it always seemed to be the community standard. Never really had an issue.

Since I built my new PC about a year ago, which on all accounts is superior to my previous PC my video render time seems to have slowed down quite substantially. Granted, I am now rendering in 1080p. BUT - Would that actually make much of a difference, opposed to 720p? I can't confirm or deny whether I've tried rendering in 720p with the new machine as I honestly can't remember. However, I did render a 1080p video on my old PC and it didn't take anywhere near an hour! I've only rendered about 10/15 videos on my new PC over the past year, trying to get back into it. 

For example:
- a 20 minute video used to take about 15-20 minutes to render on my old PC in 720p.
- A 20 minute video will take almost an hour to render on my new(ish) PC in 1080p

Could this be due to new hardware not being.... As good? In certain areas? Or should I be experiencing a faster video render? 

OLD PC:

Windows 7 Ultimate - 64bit

Intel i7 920 @ 2.67GHz
6GB Corsair Dominator @ 1600MHz

Any help is very much appreciated!!

Thanks!!
Rendering in 1080p takes up more resources than 720p, so it is normal that your render is slower than usual, even though your new hardware is superior. 1280x720 = 921600 pixels per frame, 1920x1080 = 2073600 pixels per frame. The software has to render 2.25x the amount of pixels per frame, so you can expect it to take about twice as long.

the 770 GTX has 1536 CUDA Cores, the 260 GTX has 192, so your new graphics card is far superior for video rendering. In theory it should be a lot faster for video rendering.

Depending on your version of Sony Vegas, you can enable CUDA for your Nvidia graphics card, this should increase the speed. Go to Options >> Preferences... and go to the video tab. In version 12.0 there's a dropdown menu labeled "GPU acceleration of video processing". Set the value of the dropdown value from "Off" to your Graphics Card ("NVIDIA Corporation (GeForce GTX 770)")

If you're not using 12.0, it comes down to selecting the right render settings in the Render As... menu. Since you're uploading to YouTube, I recommend rendering as Sony AVC (.m2ts) and selecting the template 'Internet 1920x1080-30p'. The ratio rendering time to video length should be about 1:1. Still, Sony Vegas 12 had a lot of updates regarding GPU acceleration and rendering in general, so consider upgrading.
