Next button appear on video end

HEy David,

First, thanks for helping out!

I will try and trim the video now  with the video tools to shorten it at the end as the last few seconds are not necessary.

As for the second question, yes I am using the timeline to skip ahead and trigger the next button.

If the two timelines are different, how can I achieve the result I'm looking for ?(to be able to skip to the end if needed so that the next button is enabled when the end is reache)
