If you're doing this professionally, you need to get some sort of support/stabilizer and a more consistent look (as in post). Shakey hand-held shots of stuff that would be easily captured as stills doesn't add a lot to the clients memory of the day.

What Francis said.

Get a stabilized lens and/or a monopod (especially if working with prime lenses). Also, watch out for exposure - some shots are a little blown out. Remember that DSLR footage is heavily compressed so you won't be able to make exposure changes in post. Always meter for your subject. ML has plenty of features to help you out with these

You probably could fix a lot of these shaky shots with warp stabilizer in After Effects, but yeah better practice would be to follow the advice above.

+2 on the stabilizer idea, definitely don't want wedding videography to look like horror film footage. Use a better picture style as well, something like VisionColor or CineLook so you'll get a better starting point for any post work you're doing.
