Hi friends, Im a wedding filmer and I always look for modern Effects/Transition Plugins, which I could use on my wedding films.
I see a lot of modern movies or Bollywood movies, which uses awesome effects and nice Transition, but never was able to find it to buy or download.

For example, there are many effects which are used in dance scenes like instant popping of video frames, zoom in zoom out of frames, flashing frames, white black flashing frames, etc.

What do you guys use ?

It's just straight cuts and dissolves here. But I'd be interested in seeing your more adventurous effects and transitions.

(If a wedding doesn't have a star wipe, does it really count as a wedding video? I don't think so...)

I'm with Adrian on this....as tempting as it is to use these type of effects, it dates your work in a negative way.
You only have to look back at music videos and the like to see how something that looked impressive in it's day now looks bad. I think the best work steers clear of whizz bang effects.
For me, it's cuts and dissolves, maybe an occasional soft wipe but that's it.
The same goes for those glitzy wedding templates that are out there. Horrible!

It always depends on the client. For some the little is too much and for other the much is little. A Sparkle wipe on the rings or some toys transitions on a christening does not look bad. Some plugins for premiere that you can try is the Vitascene from Prodad and the 3D-six pack from Pixelan. Other interesting transitions can be found on Digital Juice but you must be member from 1 st October 2014.

May nice effects have been used. Still wondering what are those.

What effects? You mean the color!!! In Premiere you apply a black and white on your video then in Photoshop paint with brush the tones that you want and final you place it over your video and play with opacity and blending mode. Digital Juice had release the Drag and Drop series and VFX Motion had their own... But this one is very simple.
