[out#0/mp4 @ 0x60000032c000] Codec AVOption preset (Encoding preset for setting encoding speed (optimization level control)) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some decoder which was not actually used for any stream.

  Stream #0:0 -> #0:0 (dpx (native) -> vp9 (libvpx-vp9))
