I've never taken the time to formally write these things down, but I've certainly written and talked about them plenty, so they're not too hard to infer. I watch a lot of wedding videos, and there are warning signs that go off in my head when I see certain things. These are my pet peeves. Details to come later.

1. Excessive slow motion
2. All dissolves and no cuts
3. Sappy music
4. False romanticism
5. Excessive slow motion (I thought it was worth repeating)
6. Cookie cutter emotions
7. The dramatic dress shot
8. Soft filters
9. Cinematic styles that aren't cinematic
10. Tacky graphics
11. Slow pace
12. Lack or personality
13. 2 and 1/2 hour videos
14. Film scratch effect
15. Most old film effects in general, unless it's really film
16. Masks that show one scene faded onto another
17. No transitional shots
18. The "Big Moment" style
19. Video look
20. Excessive slow motion
