FS-4 HD Upgrade?
 

Just wondering if there is an upgrade for my FS-4 HD which will allow me to goto the FS-4 PRO HD?

At the moment, I have just .m2t available as a file format. Is it possible to get the upgrade and goto PRO HD?

Thanks
Tim

I'm probably too late with this, but I think what you're looking for is here:

Focus Enhancements

Scroll down to "FS-4 Family", and the last option appears to be exactly what you're looking for.

I'm in the same boat, you can go from the FS-4 to FS-4 HD, or FS-4Pro to FS-4Pro HD;
but unfortunately not from FS-4 HP to FS-4Pro HD

via their website as noted below: " *upgrade is for FS-4Pro HD models only – will not work on FS-4 Pro."
