Hey!

So I've been recording gameplay & 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
Asus P6TSE
Intel i7 920 @ 2.67GHz
6GB Corsair Dominator @ 1600MHz
Nvidia GTX 260 896Mb
1250w Cooler Master Real Power Pro
Western Digital 1TB HDD


NEW PC:
Windows 7 Ultimate - 64bit
Asus Rampage IV Extreme Intel X79 (Socket 2011) DDR3 Motherboard
Intel Core i7-3820 3.60GHz (Sandybridge-E) Socket LGA2011 Processor
Patriot Intel Extreme Masters 32GB (4x8GB) DDR3 PC3-14900C10 1866MHz Quad Channel Kit (PVI332G186C0QK)
Asus GeForce GTX 770 DirectCU OC 2048MB GDDR5 PCI-Express Graphics Card
Corsair Professional Series AX1200 High Performance 1200W Modular '80 Plus Gold' Power Supply (CMPSU-1200AXUK)
Kingston 240GB SSDNow V+200 Drive SATA 6Gb/s Solid State Hard Drive - (SVP200S37A/240G)
Western Digital Caviar Black 2TB SATA 6Gb/s 64MB Cache - OEM (WD2002FAEX) HDD


Any help is very much appreciated!!

Thanks!!

that is over the limit of ram. i would go with only 8/16 gb ram.

Thanks for your response. Would more RAM actually hurt my render time though, I would have thought it would just go ignored if it's not needed?

and also 720p is faster than 1080p because more resolution pixels more fps you lose but this system should run 1080p without breaking a sweat.

id say stick with only 8gb ram if possible and tell me how it goes :) .

Does Vegas support GPU processing? If so, enable CUDA and see if that helps.

I'd also consider capturing and encoding at 720p, since I'm not sure you'll see any difference between the two on youtube.

Are you using the same codecs for capture and encoding?

IIRC, Vegas has a scratch area for temp files. Make sure it is on your SSD.

Have you tried doing the same vid at 720 on each rig to compare times - also the 260's DRAM is 448bit vs the 770 using 256 bit

If 720p / 1080p is a huge difference there's no pay off for 1080p anyway I don't think. Fraps captures in AVI and my output is an MP4. However, MP4 to MP4 doesn't actually make much difference in terms of render time.

I'm not sure what you mean by scratch area. But my Vegas is installed onto my SSD. Should the files I'm editing also be on the SSD and written to the SSD? I've tried this and using my other hard drives and not seen much difference but have seen that it can be beneficial to use different drives?

Thanks for your reply!

Unfortunately my old rig is dismantled. Will the loss of DRAM make much difference? Honestly not sure what DRAM does.

Thanks for your reply

The more DRAM you have, the more of the data you are working with can be held in the DRAM itself, which cuts down on the number of times the rig has to read or write data to the HD and/or virtual memory, can try rendering a 20 min video in 720 with the new rig, should go quicker that the 1080 to get a better comparison
