Hi Aggelos
Your main video clip goes on Video Track 1
Your Image goes on Video Track 2 as the overlay image.
Click the right hand box on the thumbnail for the overlay image and add the Shatter transition for your designated duration.
Now click the box on the thumbnail marked FX
Choose the Transparency effect. This will show 50% Opacity as a default, and the red cursor line will be at the left end of the box. (If it isn't slide it there.)
Next, slide the Opacity slider to the extreme left (0% Opacity) You will see the blue line in the box move to the bottom.
Click the green cross. This creates a keyframe.
Now move the red cursor line a short distance along on the right. Use the time scale along the top to estimate how long you want to fade-in for.
Next, move the slider to the extreme right (100% Opacity)
The blue line will now be slanting up to the top of the box. This represents a fade-in from 0% opacity to 100% opacity in the time indicated on the scale at the top of the box.
Moving the cursor along a little will show you that you have now got two keyframes marked by the small blue squares fixed to the blue line.
Click the Apply button.
When you now play the sequence you will see your overlay image fade-in and end with the Shatter effect.. Which I think is what you want.
If the fade-in is too short or too long simply click the FX box again to open up the effects window and alter the position of the upper marker by dragging it left or right to lengthen of shorten the fade-in. Keep it at the top to maintain 100% opacity.
The blue line should start bottom left, rise diagonally to the top and then remain horizontal to the end of the clip.
Note: You can equally apply more keyframes at other points of the blue line to create changes in transparency during the time the clip is played or to create a fade-out etc.
The effects can be applied and varied in a similar fashion to clips as well as overlays.
