Summary:  "Agur, Olentzero, agur" ("Goodbye, Olentzero, goodbye" in Portuguese), is a film produced by the EITB about the character from Basque mythology, Olentzero, and aired in 1997.

It is the second film produced about this mythology, in which the origins and beliefs of Olentzero are told.

Olentzero is a charcoal worker who on Christmas Day brings gifts to Basque homes. In other words, it's like Santa Claus, but with a different origin and context.

In this film, Itziar Ituño plays Miren, marking his first work on television and at the station where he would carry out numerous works in the future. 

The film, with audio in Spanish, was publicized/made available by different channels on youtube, being better known by Itziar fans through the Planeta Ituño channel.

However, as the film is relatively "old" (90's), the quality is not the best, both the audio and the video are not very "clean".

So I tried to edit the image and especially the sound to reduce the noise a bit to make it less annoying.  It still has a certain "hiss" in the background that it is possible to remove, but it would end up losing some of the background sound or leaving the sound a little muffled, so I chose  make so many changes and compromise the audio. I think it already helps to make the sound less annoying.

In addition to the film, there is a small making of, let's say, that the EITB did about the film before it was shown on TV, presenting some information and curiosities.
