The EffectInsBefore method inserts an effect into the object at the specified priority level.
HRESULT EffectInsBefore( IAMTimelineObj *pFX, long Priority );
Pointer to the IAMTimelineObj interface of the effect.
Priority level at which to insert the effect. Use the value 1 to insert the effect at the end of the priority list.
Returns S_OK if successful or E_NOTIMPL if the object is not an effect. Otherwise, returns another HRESULT value indicating the cause of the error.
The start and stop times of the effect are clipped within the bounds of the object's time range, if necessary. If there is already an effect at the specified priority level, all the effects from that point on move down the priority list to make room for the new effect.
