Hi Gunther,

I installed LRT 4 Pro today and wanted to do some test runs. I followed the standard workflow with export from Lightroom CC. After exporting the Raw-files to full-size Jpegs, I selected the settings for the LRT Renderer. After clicking the "Render Video" button, I get an error message saying:

The external encoder returned an error.
Please check the log file (info/log) for details.

I've tried different render settings, but that makes no difference. All the indicators for 64 bit, ExifTool, FFMpeg and DNGConv in the top-right corner are green, so appear to be ok? By the way, I'm on a mac running OS X 10.8.5.

Please find the relevant part of the log file below:

Any idea what might cause this?

Regards, Jorrit

I could only imagine that some other software have overwritten the ffmpeg encoder and replaced with an older / other version.
Please try installing LRTimelapse again, then try rendering again (don't need to export from Lightroom, just open the render dialog in LRTimelapse and select the LRT_ intermediary sequence and try again.
