Moving Text on Video Short Movie

Help/How To
8

Hello,
Still practicing those “Lines going up”. Thanks again for the demos, it helps.
But still have some questions:

  1. In a text filter I clicked on the “Background color button”, selected a color but it did not suit me. Could not remove that background color, only to delete this filter and rebuild it again. Some other way to remove that background color ?
  2. Is there a limit of video tracks in a project, not too many, I am thinking up to 10 video tracks.
    Answers will be appreciated.
    Thanks
