Unknown export failure

1. offizieller Beitrag

    Hi, I'm having a weird problem with the trial version of Voukoder Pro and Premiere Pro 26.3.0. I installed the latest version of Vokoder and and FFMpeg and set up a system variable for its folder. When I try to export with default settings, I get the following error:

    I thought maybe the program couldn't find FFMpeg or my installation was missing something, so I installed the version linked here. Same problem. I uninstalled program and reinstalled it. Same thing. Then I noticed that I had an older version of Voukoder (2.0.12) that I never got a chance to test. I tried installing that instead and the default scene export worked. But when I changed it to other encoders like LiBSVTAV1 or LIBAOM-AV1, it failed with the same error. I uninstalled the old version, deleted all the Voukoder folders on C:\ and installed the latest one again: same error, even with the default scene. Changing debug to trace didn't help:

    Code
    Export Error
Exporter returned bad result.
Writing with exporter: Voukoder Pro
Writing to file: I:\Premiere Projects\TEST.voukoderpro
Around timecode: 00:00:00:00
Component: Voukoder Pro of type Exporter
Selector: 9
Error code: 20

    Any idea what the problem might be?

    A good idea is to install only one version of "Voukoder Pro" at the same time. Each version of Voukoder Pro binds to exactly one major version of FFmpeg. (Version 2 binds to FFmpeg 7, version 2026 binds to FFmpeg 8).

    Best would be if you delete everything "Voukoder Pro" and "FFmpeg" related and install the latest Voukoder Pro and the latest FFmpeg afterwards.

    A good test to check if everything works is to run the "Designer" app and perform a "Scene Test" using the play button in the toolbar. If that is working fine then all components are properly installed.

    If it is not working please send me the Voukoder Pro logs.
