Determining the best possible render time for my system

hughdemand wrote on 6/6/2018, 6:10 PM

Hi folks

I have been using Vegas Pro since V 9 and have just updated my V15 to Build 361.

How can I determine if I have the optimal settings and am getting the best possible render times from my system.

 

I have a

  • HP Z440
  • Xeon Processor
  • 32 GB RAM
  • AMD FirePro 5100 video card

Are there settings I should be adjusting or what signs can I look for that will tell me things are going well as can be expected.

 

Thanks

 

Whit

There are no benchmarks for render times because each source, project, and render is different. You should use 6-8 threads for optimal CPU utilization, other than switching codecs and profiles, your tweaks are likely to make little difference. Of course, a 480p file will render a hundred times faster than 1080p.

Are you having a problem, or just out chasing rainbows this afternoon?

i guess i have to say "chasing rainbows" !

Awhile back i upgraded to V15 as it sounded like there might be faster render times. i just want to be sure i am using the software to its fullst potential.

i dnt know or understand the intricacies of things likeGPU usage and "threads" as you mentioned. it is things like this I would like know how to change/optimize.

 

Any hints?

thanks

What do you plan to do with the rendered videos?

How important is quality vs speed?

thanks for the reply.

the video will be just video hilites fron hockey games, which are destined for the web.

would like to optimize the settings. dont want to end up using a cadillac as a taxi/uber.

thanks

To find the speed improvements you have heard about, choose the MAGIX AVC/AAC MP4 rendering format. You may see templates in the right column with "VCE" in the title, so choose one of those that matches your media/project/delivery settings. I don't have a VCE-capable GPU so I can't help much more than that. If you don't see that then just choose a template that matches your settings. In the Custom Settings dialog for that renderer, you will see an "Encode mode" section at the bottom. You should choose AMD VCE in that section so that it leverages the hardware encoding functionality of you GPU (if it even has any; I don't know how good VCE-rendering support is on your particular GPU).

You should also be able to find those settings in a MAGIX HEVC rendering format, but things will probably be faster for rendering and playback if you stick to AVC. Possibly more stable too.

Before you render, take a look at this post about AVC quality, in particular section 1 about preparation. Unfortunately I haven't updated the post yet for VP15, as things are changing so quickly, but the fundamentals of preparing for a quality render are unchanged: https://www.vegascreativesoftware.info/us/forum/faq-how-can-i-improve-the-quality-of-my-avc-h-264-renders--104642/

Note that the quality of hardware encoding via VCE/NVENC/QSV can be inferior to CPU-only rendering. Opinions differ on this and it depends on the settings and hardware spec. Try both an make a good visual comparison.

Others with AMD GPUs should be able to help with specific VCE settings.

Thank you Nick.

 

I did note the VCE in the option column so I will definitelty give that a try. I think this only appeared when I installed build 361.

I will also now read your linked article.

Thank you so much for this help.

VCE rendering is brand new in build 361. Don't be surprised if there are issues with it. Let us know how it goes.
