Are you using the most recent version of Graffiti? If not then I'd suggest upgrading to take advantage of the many new filters that were added with the new version. If you are already using the most recent version, then you might consider either (a) upgrading from Graffiti to RED which includes all of the BCC 7 filters, many of the FEC filters plus a ton of additional compositing and titling features or (b) trying BCC and/or FEC in Graffiti. It would be much less expensive for you to upgrade to RED though ... I think that upgrade is something like $699 but buying BCC or FEC would be $999 each or $1095 for both together. If I were in your shoes I'd upgrade from Graffiti to RED.
