I am trying to add names and job titles (underneath the names) to a video like they use on news shows when they introduce a new guest. Are there any plug-ins for this in Vegas or are there any I can purchase?
you can use the text plugin or protype for the text. You can mess with generated media & masks for the lower third (that's what the graphic is called) or you can make one in a graphics program & bring it in to vegas. There are plugins & what not you can use. The sony production assistant has lower third presets. I also think you can buy them @ places like digital juice.
"Ultimate S" by the guys at VASST.com also does lower thirds stuff. You can look to see if their pricing/options work for you. I've never used the lower thirds, so can't comment on that, but Ultimate S does lots of other outstanding things to save you editing time.
Digital Juice has tons of lower thirds options, most of them animated graphics, which might be more than you're looking for. Look at their Editor's Toolkit or Toolbox for your "kitchen sink" option, or their Editor's Toolkit Singles (one theme only) for as cheap as $6 (gray rings current price). Digital Juice has also got some outstanding training videos on their site.
Highly recommend you search this forum for "lower thirds" & you'll find tons of other useful info!
P.S. You can build very simple ones yourself inside Vegas using media generator for a solid color/gradient/whatever & the cookie cutter tool to reduce it down to your "lower thirds" size. You could also build a little more sophisticated lower thirds graphics in whatever graphics program you have (Paint Shop Pro, Photoshop Elements, etc) and then export them as a PNG file for Vegas. Don't forget to add a shadow on your lower third track to give it a little depth above your video.
Click on Track Motion & then check the 2D Shadow box near the bottom left. Click on the word "2D Shadow" to make the control options for the shadow visible (if they weren't already). Now you can position the shadow relative to the original (i.e. set light direction) & change the fuzziness of the shadow (i.e. add to the height effect). You can change the shadow color if you're looking for more of a graphic effect instead of a pure shadow.
The shadow will follow whatever shape you have in that track (i.e. a video will just have a rectangle shadow, but text on a transparent background will have individually shadowed letters).
