Because the frame images in the subject strip are already the processed ones, hence we are spared of the Alpha Blend processes among the individual frames themselves when the file specified that the Blend Op for a particular frame is AlphaBlend (as contrast to the other Blend Op). Next i- A little bit of time should be deducted from the "1 second" requirement, for the the time used in processing AlphaBend.
