I made this Like & Subscribe overlay (with transparent background) a few months ago.
The ZIP file below contains 2 .mov video files. One silent and one with mouse-clicks and notification bell sounds.
like-subscribe-bell.zip (6.7 MB)
Easy to use: Just drop one in your YouTube video project.
Resize and reposition if needed.
No background to remove. The Chroma Key filter will often leave greenish and jagged borders when using low quality clips with a green background.
