I fixed the last issue, I didnt see about no spaces in folder destination.
But a new issue: The output video wont play on the 3DS, it says the video format is not supported...
The finished video is never output to the selected folder.
When I convert a video, I can see it creating the left/right/temp videos, then after they disappear, there is no finished video in the selected folder.
(Latest version, btw)
