Is this because my command line is missing some parameters, and if so, which

Hard to tell because you haven't included the _complete_ command line.
Don't hesitate to let me know if you need any further technical
information ; thank you in advance for your advice and help.
As before, always post the complete and uncut command and output (as _text_
in the email, not an attached image).
See the FAQ at https://ffmpeg.org/mailing-list-faq.html
