By nonscripted I assume you mean the command without the variables. Here it
is:
ffmpeg -y -i "inputVid" -c:v libx264 -preset fast -b:v 480k -threads 0 -c:a
libfdk_aac -b:a 128k -f mp4 "outputVid.mp4"
here is the ffmpeg output from the server I'm using to transcode:

Use -h to get full help or, even better, run 'man ffmpeg'
I compiled it using the instructions here:

I'll look into the "-movflag faststart" option. Thanks for the tip. Let me
know if you need anything else from me.
