I don't think I can understand what your problem is. Is the video in fact working or is it playing 4x?
Do you mean Render (hitting the Enter key to provide for the smoothest possible playback), or do you mean Export, creating an output file from your Timeline?
For either, can you tell us your Sequence Preset, and your source file(s) specs.?
If the latter, and you are Exporting, what are your Export settings, in full?
