Nexrender: Error: Couldn't find a result file

[FinnFrotscher]

I am getting this error when rendering. Any idea of the origin?
I am on the newest version of both globally installed cli and node modules.

It just stops.

Seems like aerender doesn't like something that goes inside of the aep project.
And it renders just fine if you use GUI for that, correct?

[FinnFrotscher]

I opened the template and ran the script from the vscode devtools. no issues. I have not tried actually rendering the project from the gui. will do an report back.

[phlexib]

I had a similar error message. It appears that in my AE project, the default Output Module codec was actually missing. I changed the default OM template and everything worked fine. Maybe that can help someone having the same error

[FinnFrotscher]

yes. i solved it the same way.
side question. is it possible to render directly to mp4 on mac & ae2020?

[inlife]

Unfortunately aerender does not support direct render to mp4 since AE CC 2015, iirc.

[FinnFrotscher]

this problem came up again and I do have the default output codec.
could you share your setup and how you build it? maybe it will lead to a fix.

[inlife]

hey @FinnFrotscher
is the question directed to me? if so, could you please explain in more details what do you mean

[FinnFrotscher]

hi,
the question is both for you and @phlexib, or anyone who has the answer :)

my issue is the following:

• i am running the renderer on a template.aet.
• during startup, after effects throws an error:

aerender version 17.0.6x35
PROGRESS: Launching After Effects...
PROGRESS: ...After Effects successfully launched

[ERROR]

"Couldn't find a result file"

• i do have the apple pro res codec installed. i both checked the installed software registry, i have rendered with this setup in the past in ae headless mode and since the issue came up, i tested the rendering using the interface and it worked. therefore codec is not the issue.

• i tried the template with and without a render job in the queue, as seen in the screenshot. both yield the same error.
  

[FinnFrotscher]

I am getting this warning when rendering using the interface. maybe its a clue.

after clicking ok, it renders w/o problem

[FinnFrotscher]

I am getting the same "existing files" message when rendering from command line and its the last message before stdend.

I'm getting the same error.

The strange thing is, that there is a file called result.mov in the nexrender directory, which I can playback perfectly fine.

[phlexib]

The problem happened to me again when switching from Mac to PC. Fixed By removing everything from the render queue.
Try that.

[j4rnold]

Thanks for your suggestion but unfortunately this didn't help.
The project can be rendered without any errors from the commandline using aerender and the GUI. As soon as I use nexrender-cli, the rendering fails. When looking into the nexrender temp directory, I can see all job related files including the result.mov file. Even the log file says that the rendering finished successfully.

[inlife]

That sometimes happens, when the after effects returns exit code which is not 0. Could you try to check what is in the log, maybe even tho rendering finishes, there are some errors that cause aerender itself to fail?

[j4rnold]

Thanks for your help.
There were indeed multiple errors in the log:

FATAL CreateProcessWithTokenW failed with error: 1314
INFO  Failed to launch IPC broker with medium Integrity level due to error:1314, launching it with default level

These two had to do with AdobeIPCBroker and could be fixed very easily.

Edit

Looks like I was happy too early.

I'm running the latest version of After Effects on a Windows 10 machine. nexrender is version 1.16.2

Any help is greatly appreciated.

[FinnFrotscher]

i fixed my specific issue by wiggling my after effects default renderer output module and the renderer settings configuration.

[gen4sp]

@FinnFrotscher same problem. How exactly have you resolved that?

[j4rnold]

Fixed my issue by uninstalling and reinstalling After Effects.

[MrSKYone]

I, too, am having this issue. Any specific protocol to fix this?
Reinstalling didnt fix the problem :/

[FinnFrotscher]

i vaguely remember. you need to build an Output Module Template and a Render Settings Template at Edit > Tempaltes > *
I dont remember the setup i used.

[Wence-May]

Hi,
to make an addition,
I found that something wrong with templates can also lead to this error.

At first, I ran into this error. I was quite sure nothing was wrong with my OM/aerender. After I reset the property "postion" of one of my layers(it had been accidentally changed), the error just gone.

I don't know how, but you may also check the .aep template.
