AVI is a Graphhic animation format. AV stands for Access violation....

No it's simply your code... Think of 'tl' as a big pointy finger that points at yout
TList
object. You have to tell 'tl' where to point with a := as in
procedure TForm1.Button1Click(Sender: TObject);
var
tl : tlist;
begin
tl := TList.Create;
try
// No need to tl.Clear because it's always empty when created.
finally
tl.Free;
end;
// The Try...Finally...Free...End... is there to fullfill your responsibility of
freeing
// objects that you create so that memory is returned to the system when you're
// finished with the object.
end;
