UPDATE (3 October 2019): According to a comment (see below) from the maker of the video,

The Poem is from Sylvia Plath and the video making is from Lina Gaitán. The video was made for a film screening in Cali, Colombia, of the movie “Sylvia” by Christine Jeffs.

ORIGINAL POST: According to the description at Vimeo, this videopoem was the opening clip to a 2003 film by New Zealand director Christine Jeffs called Sylvia. Lina Gaitán supplied both the reading in English and the Spanish translation for the subtitles. The introductory text in Spanish points out that this was Plath’s last poem, written four days before her suicide (though other sources claim it was written six days earlier, on the same day as another poem, “Balloons”).
