Returns a video clip made by clip by concatenating several video clips.
(Concatenated means that they will be played one after another).
if the clips do not have the same resolution, the final
resolution will be such that no clip has to be resized. As
a consequence the final clip has the height of the highest
clip and the width of the widest clip of the list. All the
clips with smaller dimensions will appear centered. The border
will be transparent if mask=True, else it will be of the
color specified by ``bg_color``.
Returns a VideoClip instance if all clips have the same size and
there is no transition, else a composite clip.
Parameters
-----------
clipslist
A list of video clips which must all have their ``duration``
attributes set.
transition
A clip that will be played between each two clips of the list.
bg_color
Color of the background, if any.
transparent
If True, the resulting clip's mask will be the concatenation of
the masks of the clips in the list. If the clips do not have the
same resolution, the border around the smaller clips will be
transparent.
padding
Duration during two consecutive clips. If negative, a clip will
play at the same time as the clip it follows. A non-null padding
automatically sets the method to `compose`.
