Hello,
i am testing this and it works however it encodes the proxies and not original files.
I am using built in proxy workflow on premiere and confirm that output uses the proxy file not the highres original.
I am check this also by viewing the preview image in the Export Settings in premiere. When i choose h264 it shows high res image, when i switch to vookoder it shows proxy image.
Maybe a known issue but i post just in case.
thanks
