How to apply effect to a certain time frame?

Question

Hello everyone,
I was just wondering how can I apply an effect to a full avchd file, but specify what time frame it will effect?
Say if I want the video to be black and white for the first 5 seconds and then transition from that black and white into color how do I actually do that?
Do I need to split the video up into pieces and apply the efect to each piece? How do I split the full video into smaller sections in Premiere Pro if so?
Thanks.

Is there a way to customize the cross dissolve at all? It seems a bit basic. Or are there any cool techniques you suggest I do with the cross dissolve?
You can adjust the Duration of the Cross-dissolve. In the stated case, you are trying to add an Effect to only part of the Clip. The reason for the Cross-dissolve is to ease the viewer into the Effect, so you want the Cross-dissolve to be essentially invisible.
Even with Transitions that are not "easing" the audience into an Effect, I usually keep it very simple. Butt-cut, Dip-to-Black and Cross-dissolve are what I use 99% of the time. Most of the rest have never been used, with perhaps an exception for Titles and their animation.
The Keyframing can allow for this too. A good, simple approace would be to go to the Effects Control Panel (where you added your Keyframes), and Rt-click on the first one, choosing Ease-Out from the flyout menu. You'll notice that the graph of your Keyframes now looks different, as does the icon for the Keyframe. Go to the next Keyframe, Rt-click and choose Ease-in. Notice the changes to both that icon and also to the graph. If you look closely, you will see that on the graph, each Keyframe now has a pair of "handles." You can click and drag on the point on these handles to alter the velocity of the Ease-Out/Ease-In functions. Note: there are many more ways to alter the velocity, but this is a simple starter example.
Good luck,
