How to slow down a time lapse video taken on my ipad air, done by mistake?

I took a lovely video of a mother woodpecker feeding her baby, and then pressed the time lapse feature by mistake.

You might have to slow it down using iMovie or another third party app.

This might be something to look at, if you haven't already:

You are not going to be able to "slow it down". The time lapse "video" is really a series of individual stills. The data in between those stills does not exist (was not recorded). What you have is the best you are going to get.
