13Pinnacle Systems TARGA 3000
Again, the distorted display of non-square resolution video on the computer screen will not
affect how your video looks when you output via serial digital to a video monitor.
Note: If you are editing a 16:9 project in Adobe Premiere, your computer screen previews will be further
distorted due to the fact that you cannot set these previews to a 16:9 aspect ratio. Again, this will not affect
how your video looks when output with serial digital, except as described immediately below.
Effects, Transitions, And Titles
There are still a few video applications that calculate their effects, transitions, and titles
based on an assumed square pixel aspect ratio. Those effects and transitions that are
geometric in nature, as well as titles, will appear slightly distorted when rendered to the
serial digital format. For example, in NTSC, a circular iris transition will appear as a
slightly elongated oval when it is calculated. The angle of a page peel will be slightly
steeper than 45 degrees. Titles will be rendered slightly taller. The distortion is greater if
you are editing a 16:9 project. The extent to which these slight distortions matter will
depend on you and your audience.
Note: The TARGA 3000 always works in native CCIR 601. No distortion will occur if TARGA 3000
effects, transitions, and titles are used. Also, no distortion will occur if the effects, transitions, and titles used
are CCIR 601 compatible.
