The video contains simulations made by Nils Berglund: here is the link to the original full video showing you both the wave patterns as well as the energy distribution on an eLog scale:    • Coherence of waves with random sources

The video contains several static images taken from various videos about single electron interference. These were incorporated assuming they fall under "fair use":
Dr. quantum:    • DR. QUANTUM - DOUBLE SLIT EXPERIMENT  
Prof. Dave:    • The Double-Slit Experiment  
Eugene Khutoryansky:    • Quantum Mechanics:  Animation explaining q...  
The Elegant Multiverse:    • Видео  
Did I forget anyone? Please let me know and I will set it straight.
