If you aren't proficient in using NLEs for keying, switching and compositing, then you are presumably a hobbyist. and even then, if you've mastered a keying/switching system, most NLEs do so much realtime rendering these days that you should be equally capable of quickly adapting to and using such systems. and it's not easy unless you're a keying/switching expert. Then you have to go back and correct, over and over again. ![]() Why? Because whatever time you gain in immediacy, you lose in accuracy of your timing. Trying to do live keying/switching for what will ultimately be a taped program or go to DVD doesn't make much sense, IMO. whereas the keyer/switcher provides immediate response, the NLE provides unmatched flexibility, scalability and allows you to plan, storyboard, execute and correct your edits. unless your interest is exclusively in live broadcasts. It makes no sense to want these things in a post-production environment over a digital non-linear editing system with a software based titler (like Livetype). then look for an analog keyer/switcher and a character generator to interface with the keyer. If what you want is on the fly keying of text, and switching to do dissolves, cuts, inserts, basic composites, etc. However, given the fact that these other systems are so outdated, finding one might prove far more costly (not to mention technically cumbersome) than even the cheapest, most basic NLE software packages today. Well, in that event, there's no logic behind using the firewire interface or a computer in the mix for that matter. He basically sounds like he's asking for a keyer, switcher and old school CG (character generator). This lets you key in outboard equipment such as production switchers etc. You can also quick key a graphic in LiveKey as well as set key levels and allow keys to animate on and off using independently set time values.įor external keying, DeckLink Pro features 2 independent SDI outputs and genlock allowing image and key video output from the separate SDI outputs. You can choose "internal key" on all DeckLink models where keying is done inside the card and you don't need to use any external keyer equipment. Graphics with alpha channel displayed on the RGB video output will now be keyed live over any video that's connected to the DeckLink video input and then sent to the DeckLink video output. This is just like switching your video capture card into a keying card DeckLink works very differently when keying is tuned on. Key features are controlled by an application called Blackmagic LiveKey that enables keying. This is perfect for adding logos and "bugs" to live video when doing dubs of your show reel or adding copyright and not for broadcast notices to client dubs. At $300 USD for an SDI board and software it's not that expensive.Īll SD DeckLink models now support internal keying allowing you to key graphics over live video in real time. ![]() I searched the web and was able to find a company called Black Magic Design that sells video capture cards for both Mac and pc that allow real time keying of graphics.
