Cubase 15.0.20 - Render In Place Hangs now

Cubase
1

After updating to 15.0.20, Render In Place now hangs with Kontakt 8.

After I reverted back to 15.0.10, Render In Place now works fine.

Anyone else experiencing similar?

Hi,

Are you on Mac or Windows, please? From Windows, you can generate a freeze dumpe from the Task Manager.

Hey Martin, I’m on Windows 11, 23H2.

Unfortunately I’ve already reinstalled 15.0.10, so I can’t generate a crash dump. I should have while I still had the latest version, apologies.

I’m using a Blackmagic Decklink Mini Monitor card for video output, not the internal video engine. Might that have anything to do with this?

Rendering in place an instrument, there’s no plugins on it, just routed to FX. At first I thought Altiverb 8 was the culprit, but I’ve reverted back to Altiverb 7, and the problem still persists.

It was after I reverted back to 15.0.10, then the issue was resolved.

Also, another odd thing. I also own Nuendo 15 (in which Cubase 15.0.20 should be most similar to), the latest. I tried the same setup - load an instrument, sent it to an FX channel with altiverb, and render in place. No issues! It works as normal!

I can confirm it’s a video problem with 15.0.20’s new video export capabilities.

But I’ve found a workaround - Mute the video track.

Render In Place now works as should.

I’ve now experienced this. First time using render in place since upgrading froze. C15.0.20 on W11 Pro 25H2. @Martin.Jirsak Here’s a link to the freeze dump.

Normally, I’d wait to upgrade but the ability to finally export sensible video for client reviews was too enticing to wait ..

From Chat GPT:

Cubase Render in Place thread is waiting on the DeckLink video subsystem, which never returns (deadlock / blocking call).

Why this happens:

  • Render in Place = offline processing (faster than real-time)

  • DeckLink driver = expects real-time video clock / SDI sync

  • Result:

    • Cubase tries to render instantly

    • DeckLink waits for valid video timing

    • Both wait → freeze

:collision: Important detail from your dump

This line is the smoking gun:

decklink mini monitor

:backhand_index_pointing_right: That means:

  • Your DeckLink Mini Monitor is actively initialized

  • Even if you’re not “using” video visually, Cubase still hooks into the card

While I LOVE the new video export options for Cubase 15.0.20 and Nuendo 15, it screws with audio export of any kind, be it Export or Render In Place.

I hope the Devs will investigate into this area.

In the meantime, the workaround I’ve found so far, is to MUTE the video track. Then all exports and Render In Place work as they should.

I can confirm that muting the video also allows me to render in place. I also tried again afterwards with the video unmuted and it froze as before. I think this thread might need a bug label now. What say you @Martin.Jirsak?

Normal audio export works for me even with the video unmuted.

For render in place - As a work around I’ve created a macro that uses PLE to mute the video track, runs render in place with current settings (what I use most often) and then PLE again to unmute the video. I’ve reassigned my render in place key command to the macro. Works pretty well so I won’t roll back just yet.

Hi,

I’m out of office, therefore I will be able to take a deep look after the eastern. Thank you for understanding.

I have the same problem with the UVI Whoosh, when I render in place effect, it freezes.

Hi,

Does anybody have a freeze dump file, please?

16

Hi, I’m having the same problem. Cubase 15 Pro won’t freeze or render correctly; it keeps crashing. I submitted a ticket through Steinberg, but I haven’t received a response yet.

17

Hi and welcome to the forum!
Can you attach a dump file like Martin asked, please?

Just a FYI:

Hi, shure. Where can I find them? I’m sending them to Steimberg every time.

On Windows it’s a *dmp and on Mac it’s an *ips file:

  • Windows: Documents/Steinberg/CrashDumps
  • macOS: ~/Library/Logs/DiagnosticReports (often accessible via the macOS Console utility)

Hi,

Please, attach the crash/dmp file. So far there is only one. I would like to see, if all of them are the same. Thank you.

  • Mac: macOS Console utility > Crash Reports (or ~user/Library/Logs/Diagnostic Reports).
