How to solve the problem？

[ujukauboi]

It looks like the file resulting file of aerender wasn't found. I would try aborting after it renders "[yUPo5wh1LCCYMGUQ89WG1] applying postrender actions..." and see if the result.avi made it in the folder.

[inlife]

Error message states that there is no such file named result.avi for input

C:\Users\Administrator\AppData\Local\Temp\nexrender\yUPo5wh1LCCYMGUQ89WG1\result.avi: No such file or directory

Are you sure the file exists when action-encode starts? You can check existing files in the temp folder.

I can find aerender in my win10：
MINGW64 /d/project/ifly/video/nexrender (master)
$ aerender -version
aerender version 16.0x235
MINGW64 /d/project/ifly/video/nexrender (master)

C:\Users\Administrator\AppData\Local\Temp\nexrender\yUPo5wh1LCCYMGUQ89WG1 This directory exists，but the .result.avi file does not exist， it may be caused by the failure of action-encode.

[inlife]

no, it is caused by error in aerender

try checking the log for this job to see what happened inside aerender itself

[JamesBotterill]

are you specifying the input for action-encode to be result.avi, if you are try removing that in your json.

Thank you for your answer.

I want to export MP4 videos， I remove actions. job rendering successfully finished.

@chrstnsmthng @JamesBotterill @franeko @inlife
My problem is solved, thank you for your answer.
Steps to solve the problem:
This is due to the inconsistency between the layer composition name in my ‘aep’ file and the name synthesized in json.

[inlife]

Glad to hear that, cheers!
