How can i erase a black background from a motion graphic video like this one? -> Motion Graphics - Fire Torch | VideoHive
Please reply me, it would really be appreciated
That clip comes with an alpha chanel so when you composite in AE you should not have to do anything. If you have a fire clip without an alpha chanel on a black background you can use the Screen or Add blend mode or download the Unmult plugin from Red Giant. It is free. Unmult only works with 100% black backgrounds.
There is no way to easily make a transparent background work in a media player like QuickTime or Windows Media because media players do not support transparency.
Thank you very much, it worked!
