To see the Effects that you have added you need to view the clips Properties Panel. In PE7 you click on the clip in the Timeline to select it, then click the Properties icon, it is above the Timeline, over to the left next to the slider. Otherwise left click on the clip and select Show Properties. The Properties panel will appear and the effects are listed there. To delete an effect, select it in the Properties panel and hit delete, or left click on the effect and select clear.
Note if you apply a motion or picture-in-picture preset you will not see any applied effect as these effects make use of the Motion effect which is bu default always in the Properties panel.
ahhhhh, well, since the only effects i have applied have been pans and zooms, i guess that would explain it.
so to remove a zoom, i would simply set the first and last frames to 100 and it's done with?
but to remove a pan, how do i delete the effect?
Same as setting the Scale back to 100% you need to set the Position values back to their default values of 360 and 288. If you look at the Properties of an untouched clip on the timeline you can see what all the default values are.
Or, if you open the Properties panel for the still, you can simply click to select the effect (Motion, in this case) and click the Reset button in the lower right corner of the panel.
Sometimes, though, preset effects add additional Motion effects to the Properies panel. Those can merely be selected and deleted.
