Ever since Cubase 15, it seems Render In Place has severe regressions. First, the new Video features affected RIP, and muting the video track seems to work - if the track count isn’t massive.
Now that that bug has been “solved”, it STILL seems RIP has problems. I tried RIP-ing about a 100 tracks yesterday, and the further the process went on, the longer the rendering took. After every event rendered, it would stay stuck at 100% for a very long time. I’m talking like 5 whole minutes. Before the next event render happens.
I had to force-quit Cubase a couple of times.
I also tried inserting an empty video track and muting it manually, and it seemed to improve things alittle bit. But in the end, things didn’t really change. It still gets worse as the rendering process drags on.
And here’s the weird part - once RIP has finished, the entire program’s reponse is extremely jerky, and the CPU load goes CRAZY. Almost like as if it got traumatized by Render In Place.
I have “Track Selection Follows Event Selection” option always enabled. But the problem is, arming tracks will put the CPU load into action. And if massive amount of tracks are armed, the CPU load gets even worse. Maybe this is why when I select Events to Render In Place, and if I select ALL of them, ALL the tracks are getting armed all at once, severly burdening the Render process?
I’m going to experiment and try whether unchecking the “Track Selection Follows Event Selection” option will make a difference.
Okay, I tried disabling all convolution reverb plugins, and this time, the results were much better. But the CPU load still became jerky and very slow.
Cubase 15 clearly has a memory leak problem - where after Rendering In Place a huge number of events, it just gets worse and worse.
Oh btw, it really isn’t the CPU getting affected. I checked and it’s actually the Memory RAM that’s going way out of control. I have a good feeling it’s a memory leak.
Thanks for the screenshot.
Another question in order to be able to set up a repro: You wrote that you rendered a hundred tracks but RIP usually renders events/parts. How many events/parts did you have to render per track on average and over how many tracks were they spread?
All MIDI parts (there’s alot more but I can’t fit all into one screenshot). As I already mentioned above, I also tried turning off “Track Selection Follows Event Selection”, which allows me to select the events without arming the tracks. Also made no difference.
I just tried another trick - using Process Lasso to “Trim Memory” once the RIP is done. But it doesn’t work either. Once Cubase finishes a heft RIP, it becomes extremely jerky amd unsable. I have to quit the project and close Cubase, then open it again.
In case this might help, I’m using Blackmagic Decklink Desktop Video, v15.3.1. Does anyone think this driver version might be the cause of the problem? Even if the video track is muted?
Okay, removed and reinstalled Blackmagic Decklink 14.2.1, which Steinberg seems to recommend as the “sweet spot”. Loaded the project back up, tried RIP again, but looks like it made no difference. Cubase still ends up stuttering and hardly able to playback once RIP is done.
