You need to at least show your ffmpeg command and the complete console output.

What player are you using?

Are you actually using ffmpeg?

ffmpegX is not the same as ffmpeg. It is a front end that comes with a very old version of ffmpeg.

I would suggest ditching ffmpegX and installing the real thing. This will require learning to use ffmpeg from a terminal. It is a steeper learning curve, but once you get the hang of it, you'll probably start to prefer the CLI interface. The added bonus is that you can copy/paste the command used so that people on forums like this can help you. When using a front end like ffmpegX, we have no way of knowing what options were set in the GUI interface. Furthermore, there are lots of options available that the GUI does not expose.

MacPorts is a good resource to use for installing ffmpeg on OSX.

Oh my word.

Thanks for your detailed response. I might just find someone else to it .
Not sure I have time for all that right now.

I was only using this old software as the tech bods who own the screens where our video will be displayed recommended using it.

It all sounds rather complicated.. terminal windows scare the pants out of me !!!

Thanks

Chris
