Seems I may have missed a step... I followed the prescribed instructions, restarted movie maker (even rebooted), but I see nothing under Transitions to indicate the new feature. One thing I did not see in the steps was what to name the notepad file as; so I named it 'comp a add b b add a.txt' as per the code name. Was that incorrect?
Also, allow me to detail further what type of effect(s) I am hoping to generate: back in 1975 I made a Frankenstein movie and in it is the obligatory lab scene complete with flashing lights and lab-type noises. I would love to superimpose your great looking Energy-Camera-hit_red.avi onto the existing scene. But the option to drop a clip on to a clip or place it in the title overlay track does not appear to be available.
So please let me know what I may have missed!
