GPU Powered Renders -&- 1080 60P output CODECS

Hi

Brand new to Vegas, just started using it last week

I am working on EXTREMELY computer intensive video tasks

I am managing 150 Mbps, UHD 60 P files, mixed with 2.7K GoPro Files with slo-mo, keyframe & cropping, transitions, title overlays. When all is said and done the files render to just over an hour long at about 28 GB's.

There seems to be a lack of 1080, 60P render options. I am currently using Sony XAVC S Long. I was using a consumerish editing system that gave me a render option of 1080 60p at 28 Mbps, and my files rendered to about 13 GB. Is there any way to adjust the render bit rate on the CODEC I am using now ?

The reason I am not usnig the previous editing system is because the software can't manage the files properly, Vegas Can.

In a nutshell, I am looking to render at 1080 60P at about half the bit rate of the current XAVC s Long option that I am using now.

ALSO

When I rendered on the consumer editing system my CPU would rarely hit above 20%. When I render on Vegas my CPU is hitting about 70% and above. I am not sure if Vegas is properly using my GPU Card (GTX-980 Ti) but I find the CPU levels on the high side. I found a GPU option in preferences that I have checked off but is there anything else I should be doing to ensure my GPU card is being properly utilized ?

Thanks.

"1080 60P at about half the bit rate of the current XAVC s Long" - Are you looking to render to "Sony AVC.mp4" or "XAVC.mxf"? Both are capable of 60P. Under XAVC you jus select a 1080-59.94P profile. Under Sony AVC, you may need to select an "internet" profile and modify it to be 59.94 FPS, Progressive, and then set your bit rate. Use the help file to determine how to create a custom render profile.

The GTX-980 Ti is a nice card, but it is not your best choice for Vegas performance. Swapping out that card for an AMD hd 7970-ghz, R9-290x, or 390x would be your best bets to accelerate what you are trying to do.

GPU-Z, under the sensors tab, will show you if your GPU is being utilized during rendering or playback.

If you are just using Vegas as a video compressor and not FX and editing. You may want to consider learning how to use FFMPEG, or see if Handbrake will do what you need to do.

The Sony XAVC S Long 1920x1080-59.94p render templates do not expose a bit rate target like the Mainconcept and Sony AVC/MVC render templates.

You might look at the Vegas2Handbrake workflow as Handbrake is more flexible in setting target quality or bit rate. Additional Information

thanks astar

I am not sure what you are referring to by

'GPU-Z, under the sensors tab'

I am doing quite a bit of editing in Vegas, I mentioned it in my post. I will take a closer look at the render options you mentioned, cheers

Download this custom Sony AVC/MVC render template and place it in C:\Users\username\AppData\Roaming\Sony\Render Templates\avc-sony.

You'll have to turn on hidden files in Control Panel / Folder Options. This will give you a target bit rate of 25.9mbps.
