Simply insert the video into your timeline wherever you need it to be.
Also, PS CS 6 has some limited Video handling vs Premiere Pro. What are the full specs. (format and CODEC) of your intended Video Clips? That information might determine success.
Thanks for both of your replies. I'll tackle Premiere Pro in 2013 but for now the limited PSCS6 video capabilities are more than adequate for my current project. Thanks to Adobe for including video editing capability in CS6. The answer to my question seems obvious now that I grasp how simple, intuitive and automatic the video editing features are. I'm used to more complicated workflows! In additon to these forums and your responses I accessed a nice multi-part video tutorial on using the CS6 video editing functions at kelbytraining.com.
