Trem Videos quickly with Voice over?

Hello all:
If i have a video on ios, and need to trem the end of the video, i should move my kersor, to the end by a second or less to the end, which is not good specially with long videos,
so, is there a quick solution to listn to the end and trem it quickly?
i know that i have the end slider, but need to listen to know where exactly where i end my video.
Thanks in advance
