Decklink and closed captioning
Hi,
I am researching a closed caption workflow for our FCP-decklink based systems. Has anyone here had experience with MacCaption or others? Does Decklink output the caption information properly?
Does anyone have workflow to recommend? I was considering a hardware encoder like the Link PDP-886 but it seems possible to do it all in software with something like MacCaption. Comments?
Thanks,
jason

We’ve been running MacCaption with our DeckLink systems since the first of the year and have no problems. It seems best to provide the MacCaption station with a full-res QT and then let MacCpation render the finished Closed Captioned QT. Mostly we do three line Roll Up Cpations that are occassionally repositioned to account for on-screen graphics. No complaints from broadcasters.
Also, the people at MacCpation have been great and they’ve had three upgrades so far this year (all free.)
Email if you need further detailed information.
Mac Pro, G5’s, FCP et al.

Thanks for that information David. I’d email but I don’t see an email address… so a couple more questions here if you have time.
In terms of workflow I gather you are dedicating a specific station to do the captioning. How long does it take to do one show? How long does the render take?
Thanks

We have MacCaption software installed on four different machines. The program requires the USB dongle to run so we just move it around to an open computer.
Generally, our person can close caption a simple (ie. music, narrator, one voice at a time like on-screen interviews or actor) one-hour show in about 5 hours if we have a transcript of the show before hand. She was much longer the first time or two but is gradually getting faster and faster. We only do about one show a month.
A render for a one-hour show takes about 30 minutes on a Dual2G G5.
