After watching several videos in my French Class breaking every single rule I can think of, I decided to post a list of rules not to break on the forums because im sick of stupid videos with stupid effects.
Don't Use Default Text Intros
The Text with colored background or the Text moving across the screen in 3 different places at the same time can really make people dislike your video from the start. Try to make your own introductions and not use default ones.
Transitions
Using default transitions may be easy, but using custom ones makes your video look more professional.
Color Filters
DONT USE COLOR FILTERS!!! I can't tell you how many times I wanted to slam my head against a wall when I see filters being used badily. Dont use ANY (RGB mainly) filters randomly for no reason. It looks handicapped. Sepia or Black and White filters are ok to use as long as you use them correctly.
Music Choice
If you are making a sad video, don't use "Im Walking on Sunshine" for your music choice. Pick a song that fits the video's mood, not because you like it or its popular.
Video Warps
Don't use Video warps. Altering the screen, Mirroring the screen, or any other form of warping makes your video look handicapped.
Sound Effects
Don't over use sound effects. I remember watching a Video in History last school year that used a handicapped sound effect RIGHT AFTER EVERY PERSON STOPPED TALKING.
Person Talking, Sound effect, Person Talking, Sound effect, Person Talking, Sound effect, Person Talking, Sound effect...
It gets annoying.
Add on if you would like.
