+- **`Background color`**
+    - Background color can be used for inputs with possible transparency (e.g. png sequence).
+    - Input's without possible alpha channel are ignored all the time (e.g. mov).
+    - Background color slows down rendering process.
+        - set alpha to `0` to not use this option at all (in most of cases background stays black)
+        - other than `0` alpha will draw color as background
