Pair alignment can fail to detect if there is no change #5

If the first 3 frames exhibit no physics changes (static stage with no characters on screen, or if someone started recording while paused), then pair alignment can't possibly be detected by utilizing them.

There may need to be further checks across many frames until you figure out the pairs.

Even extremely subtle changes can be missed, as video compression artifacts can cause very slightly incorrect alpha detection.

This image for example shows the error of a correct extraction (boosted to be visible to the human eye).
