Attempt Inefficient Wood Cutting

What happens here

The video shows an individual attempting to cut a substantial wooden block, which they refer to as '16x12s', using a two-person crosscut saw that is clearly much too large and unwieldy for the task. The block is securely placed on sawhorses. The individual struggles significantly, making slow and arduous progress, expressing frustration that the process 'is taking forever' and that 'there has to be a better way' to complete the cut.
