Then, we assign $new to $current so it will be the "old" bit on the next loop iteration.

然后，我们将 $new赋给 $current ，以使之成为下一个循环中的 “old”比特。

Finally, we make the starting offset for the next loop the ending offset of the current one.

最后，我们将当前的结束偏移量设置为下一个循环的开始偏移量。

The next loop section controls setting pixels coordinates only if the frame at that position is greater than the start frame.

循环的下一部分控制像素坐标的设置，条件是当前时间帧在起始帧之后。
