Learn Spanish (Latin America): ¿Quién estará grabando el video del susto? - Who could be recording the video of the scare?

In Spanish, the future tense is often used to make a guess or express wonder about something happening right now in the present. This is called the 'future of probability.' By asking ¿Quién estará grabando...?, the speaker is wondering aloud: 'Who could be recording?' or 'I wonder who is recording?' at this very moment.

We've been using gerunds with terminar and acabar recently. How does the gerund work here with estará?

While verbs like terminar plus a gerund mean 'to end up doing' something, the verb estar plus a gerund forms a continuous tense, focusing on an action in progress. Just like in English, estará (will be / could be) pairs with the gerund grabando (recording) to describe the ongoing action of filming the video.

What does susto mean, and does it relate to the verb asustar?

Yes! Asustar is the verb meaning 'to frighten' or 'to scare,' and susto is the noun form meaning 'a scare' or 'a fright.' The phrase el video del susto implies they are talking about a specific prank or frightening event, and the speaker wants to know who is capturing that moment on camera.

Why is the verb estará in the singular form?
