I’m looking for ways to speed up my renders. I always initially render regions/cd tracks from an album’s worth of regions/tracks in a montage, and have the rendered files “open in new montage”, so the renders open placed in order in a new montage, with the rendered files named as I would like them (each render file named as the cd track marker in the original montage). Renders are to the original sampling rate.
Each clip/cd track has many different clip plugins, and some of the plugins are quite slow. Oftentimes, sampling rate is 96K or 192K, or the program time is very long, further slowing things down.
I have a 6-core Xeon. I ran a test, rendering six 96K clips with plugins from a montage as I normally do, and the time to complete was 18 minutes 30 seconds. During the render, CPU reading was about 18% throughout.
I then separated the six clip/region/cd tracks into six separate montages, moving the clip/region/cd track to the head of each montage. Then I loaded the six montages into the batch processor, and set it for 4 cores. Time to complete was 6 minutes 30 seconds. CPU reading was about 68% for most of the process.
This is a major difference to me, almost 3 times faster, and just what I’m looking for, but I need to have the rendered files open, automatically placed in order in a new montage, and be named as the original region/cd track. That’s the part that isn’t being done in the batch processor. Also separating each region/track into separate montages to accommodate the batch processor is not going to work for me.
Is there a way for Wavelab to incorporate this speed increase somehow, invisibly behind the scenes, so that I can render regions/tracks “normally” as I do from one montage, but utilize the speed gain from using more cores, if I’m only rendering regions/cd tracks? The difference is so large I’m going to have to take advantage of it somehow, if it can’t be optioned into the Wavelab montage regions/tracks renders in some way.
ps. I initially set the batch processor to “all cores”, but all 6 cores maxed out and CPU sat at 100%, which freaked me out, so I set it down to 4 cores. Is it ok to run at 100% if it doesn’t crash? It seemed to be working ok until I cancelled it.
pps. Lastly, are there any disadvantages to running with the extra speed, at about 68% CPU, besides having less available CPU for other simultaneous tasks?
