The centrepiece is a seven-minute movement called Nothing To Be Written, inspired by the multiple-choice postcards sent home from the trenches.
The pre-written cards allowed soldiers to choose one of three options: "I am quite well", "I have been injured" or "I am in hospital."
They were allowed to sign their name and date it - but if they wrote anything else, the cards would be destroyed.
The VR experience will put viewers in the shoes of the soldiers and their loved ones, contrasting the horror of the trenches with the quiet dread of their families as they waited for news to arrive.
The Proms film takes a different approach, using the Royal Albert Hall to illustrate the music by having the building's walls and geometry morph and change.
"The space feels real but heightened," said Lysander Ashton of 59 Productions. "As the music begins, the hall begins to transform in response to the music.
"The architecture around you shifts and changes, becoming a canvas on which the music is painted."
The film will be released for home users on platforms including Oculus VR and the BBC website later this year.
Nothing To Be Written will also be made available as a stand-alone VR experience.
