I have a little problem with some presets of "footage: special effects", like the "ultimate lightning", for example: there is a black background all around the preset, so it is annoying for putting it into a video...
it is regrettable because this lightning is pretty good.
Is it normal?

No, it's not normal. You have to change the composite blend method which will automatically remove hte black. Refer to this knowledge base article- changing the composite blend mode
-Hope this helps

Thanks for the response, but unfortunately, it is impossible to change the composite mode. I precise that that problem comes when I use a "clip art" preset, there is no problem for the "HD stock footage presets".
Is there something else I could try?

I've just read this tutorial: http://support.fxhome.com/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=98&nav=0,2,5,40
Well, for those presets, I suppose I can't do anything for the black background to disepear...
Anyway, thanks for having responding.

I've found how to do to delete the black background: we must put the preset UNDERNEATH the video (the video is in position 1, the preset in position 2)!
I hope it can help someone one day...

The proper way to remove the black backgrounds from those files is to convert the images to JPEGs. The reason the background doesn't remove automatically is that someone (whoever created the preset in question) added an alpha channel to the images, without actually recording any proper alpha information into it. Converting them to JPEGS will eliminate the alpha altogether, and the background will disappear normally.
