Thank you for your response. Is there a way of adding FFMPEG commands to the Voukoder GUI? Below is an extract from https://www.vrtonung.de/en/ffmpeg-codes/ as one example. I just dont know how to benefit from voukoder and add VR related settings on top.
Stereoscopic to Monoscopic
If you have a 3D 360° video, it certainly looks great on VR glasses, but is less suitable for conventional screens, since one eye is enough for viewing, i.e. 2D. Here the video is halved in the middle, horizontally or vertically.
ffmpeg -i input.mp4 -vf crop=h=in_h/2:y=0 output.mp4
ffmpeg -i input.mp4 -vf crop=w=in_w/2:x=0 output.mp4
