Thanks for the quick reply. The config log can be seen at
https://pastebin.com/WeYbXiWW
Also, the full output of the command I ran is shown below. Please note the
I think the \n character is not inserted after
frame= 39 fps=0.0 q=31.0 size= 768kB time=00:00:01.74
bitrate=3596.7kbits/s speed=3.4
and they are all shown sequentially.

Codec AVOption preset (Set the encoding preset) specified for output file
#0 (../fast_video_conv.mp4) 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 encoder which was not
actually used for any stream.
Stream mapping:
Stream #0:0 -> #0:0 (h264 (native) -> mpeg4 (native))
Stream #0:1 -> #0:1 (aac (native) -> aac (native))
