Sony Vegas Pro 14 vs Magix Vegas Pro 15

Hi Joe, great video and awesome choice in getting Threadripper! Your excitement in reducing render times from your other Threadripper video motivated me to post this. Vegas Pro 15 has long overdue features including finally taking advantage of NVidia cards, like the GTX 980Ti, which greatly reduces render times. To take advantage of this they have introduced a new codec called Magix AVC/AAC MP4 which compares well to the Sony AVC codec. You just have to select this format from the render list and then select the template which is NVida accelerated, ie. in your example it would be "Internet HD 1080p 29.97 fps (NVida NVENC)". You can customize this template and specify target and max data rates. Also make sure the Encode mode at the bottom of the template is selected to "NV Encoder". There is also a NVENC preset at the bottom which is set to default but can be put in "High Performance" mode to get even better render times. If you try this I hope you will be pleasantly surprised by the reduced render times while maintaining a good quality output file. One thing I have noticed on some occasions is the target data rate on the rendered file is slightly lower then what I specified but I would simple increase the target data rate and that would fix it. I have seen this Magix AVC codec compares well to Sony AVC codec but with much lower render times. It reduced my render times by less than half while maintaining quality which I couldn't believe it at first. With your Threadripper it must be a dream combo! The rumor is Magix Vegas is making further improvements to GPU acceleration and reducing render times with other popular codecs as well. Great tips Joe in all your videos, and it would be great if you could try this and let us know what render times you are now getting and how the quality compares to Sony AVC.

Where did you get the incorrect fact that Vegas pro is made by Sony? The last Vegas release developed by Sony was Vegas 13 before it was sold out to Magix

HI Joe. AMD are known for superior OpenCL performance in general hence the mining industries grab for AMD cards first. Historically Nvidia has always had CUDA and for a long time resisting before they finally provided support for OpenCL themselves which as I understand it is basically using cuda with an emulation layer over the top. Cuda itself though is very efficient.

I have tried Vegas 14 in the past. From memory, like Premiere pro, it was only using the GPU for processing various effects that you placed on the timeline and not the main render which was still reliant on the CPU. Is that still the same for Vegas 15? Looking at the Taskmanager CPU Utilization graphs, It looked to me like the CPU utilization in the AMD render was higher than the utilization with NV in the video render tests.

As we discovered with the gaming performance tests, The slot the GPU is installed in has an effect on performance relative to what CPU core is being used to process the data on that GPU. If the data is being processed on die 0 but having to access a GPU that is directly connected to the PCIe controller on Die 1, it has to travel over the Infinity Fabric and the extra latency effects performance.

Did you notice what core the OpenCL or Cuda specific thread was running on? During a render job, it is likely to be one out of many.

Have you tried the same experiment swapping the slots the AMD and Nvidia cards are installed in?

Maybe your results are being skewed because the Nvidia card is in the 2nd slot that is connected to Die 1 on the CPU but the Vegas Cuda thread is running on Die 0?
