Pablos also received a scholarship granted by the National Fund for Culture and Arts (FONCA) to specialize in screenwriting.

Pablos earned his academic degree from the CCC with the short film La Canción de los Niños Muertos in 2008.

[4][5] For this work, Pablos earned the Ariel Award for Best Live Action Short and also the SIGNIS Award during the 4th International Short Film Festival (FICMEX), being the SIGNIS jury's verdict that "the film narrative takes us into the complexity of disparate feelings as violence and tenderness, anger and forgiveness, rebellion and reconciliation.

[14] The film was originally based on a book written by Mexican novelist Jorge Volpi from which Pablos developed a screenplay that features a love story that evolves in a complaint about kidnapping, white slave traffic and prostitution, with a "documentary tone".

[18] In 2016, Pablos worked on the film adaptation of the novel Los Detectives Salvajes written by Chilean author Roberto Bolaño.
