Vegas Pro 10 arrived today, and I used the trial to test render speeds with using the GPU, CPU and compared them to Vegas Pro 9.0.I used a one minute clip from a recent wedding, I added ONE Color Curve effect, and ONE Color Correction effect to the clip. The original clip was from a.m2t file taken off of my HVR-MRC1 recording unit (25MB/s).The only render option that I have seen so far (and there may be more) that has specifically stated a “Use GPU” option is the Sony AVC (.m2ts). I did however test not only the.m2ts rendering but also the Main Concept.m2t rendering – even though there was no option to add GPU assist – just to see if there were improvements.Before really getting into this – keep in mind my CPU is an i7-980x – which is a very high end 6 core desktop processor, and my GPU setup is 2xGeforce 285 GTX in SLI – which is pretty solid, but not top of the line in the GPU world these days. I am not even sure if Vegas takes advantage of more than one GPU at this point. THEREFORE the differences in speed listed here could be MUCH GREATER for someone who has a more common CPU.The.m2ts files were rendered in the default Sony AVCHD 15,000,000 bps, and the.m2t files were rendered with the default Main Concept 25,000,000 bps format.Since I cannot copy and paste from Xcel – and I do not have the time or means at the moment to upload a picture anywhere – I figured the best way to share this data was through video! This is a video forum after all, correct?For rendering a 32-bit.m2ts file – the GPU assisted rendering average was 4.1% faster than CPU only rendering, and 4.8% faster than the.m2ts render that Vegas 9 provided. Not as big of a boost as I had hoped for, but faster none the less.For rendering an 8-bit.m2ts file this got interesting.
Sony Vegas Pro 16.0: CPU/GPU/RAM/HDD not fully utilized during rendering. Ask Question 1. I've got a small question. Recently I started working with Sony Vegas 16 (after not edditing videos for years) and I noticed that when rendering videos, my GPU/CPU/RAM/HDD are all not fully used. When rendering a simple 2k video (2560x1440p) at 60fps where. Apr 19, 2018 - So, how do i enable it so it actually works instead of CPU. Because this render eats all cpu. Lets start with 'Perferences (+hold down shift)' so.

While GPU assisted rendering averaged 9.7% faster than the CPU only option, the CPU only option was 11.11% SLOWER than the average 8-bit Vegas Pro 9 render. The GPU option also finished very slightly slower than that Vegas Pro 9 option. I am not sure what was changed between the 2 versions of Vegas, but it seems to have become a bit less efficient on the 8-bit render end.AGAIN – The average CPU out there may show a more favorable increase when adding GPU power.For rendering a 32-bit.m2ts file – the GPU assisted rendering average was 4.1% faster than CPU only rendering, and 4.8% faster than the.m2ts render that Vegas 9 provided. Not as big of a boost as I had hoped for, but faster none the less.Then we get to the.m2t renders. Vegas pro 9 and 10 both were pretty dead even on the 32 bit renders, 10 averaging only 0.05% faster which could really go either way, and the difference really doesn’t mean much.Next came the biggest surprise of them all – The 8-bit.m2t renders in Vegas 10 averaged a whopping 38.7% increase! This renders the video in about double real time.
What does this mean? For me, I like to render small segments all the time just to see how a finished clip might look while playing smoothly at full resolution.
Yes I know there is a RAM render option, but an all out render is much more stable, permanent, and capable of being virtually unlimited in size. This is also a great option for a rough draft. Whether this is GPU enhanced or not, it is definitely much more efficient!All in all I think the upgrade will be worthwhile in my own situation. Not all as fast as I had dreamed it to be, but faster is faster.There are of course other new features that are nice. The stabilization for one looked like a nice feature to have. Although I have not used it much, I assumed it would be a plug-in. In fact, what it appears to do is render that portion of a video separately and re creates the clip.
It is a little slow, but having it I suppose is better than not. Just be careful to be very conservative on the adjustments, or you will mistakenly zoom in more than expected. It would be nice if the slider bar actually stated “zoom” on it rather than amount of stabilization.
