HELP WITH IMOVIE ASAP ? please?

Where can I download additional effects and transitions for iMovie on my Mac.

Thanks in advance.

Update:

I would prefer if they are free, but a small amount of money is okay with me.

Free sights/effects recommended though. Thanks.

Update 2:

Is anyone here willing to contact me via email and help me through iMovie?

Update 3:

P.s. How exactly do I get the “effects” on iMovie, I don’t see it anywhere..

Thanks again.

I bought this, at the time is was 15 dollars, it is really great if your looking for more effects.

Hope this helps,

Matt
