When I record a clip with nVidia ShadowPlay, it saves the video file with 2 audio channels, which is good. One for PC speaker output, one for microphone input. However, the resulting video file is huge and very poorly optimized, so I sometimes want to reduce this via FileConverter, especially when the file size is more important to be small than the video quality to be high. But I can't seem to get FileConverter to keep both audio channels in the resulting file; it seems to just pick one and discard the other. Can I somehow persuade FileConverter to keep both? Or could this be an option in settings, perhaps a tick box, whether to keep all audio channels or only one, because then I could tick that box at least there.
It is now possible to create custom preset directly with ffmpeg arguments in the advance mode. You should be able to do this by looking at the ffmpeg documentation : https://ffmpeg.org/ffmpeg.html
