You get the video you describe, so describe it the way you'd describe it to a friend. Say where we are, what time it is and what the weather's doing. "A rainy Tokyo rooftop at 2am, warm window glow, neon reflections in puddles" is already a complete brief. The box at the bottom of Studio takes 20,000 characters if you want to go further, and you won't need most of them.
Name a medium, like anime or watercolour or oil painting, and that's what renders. Ask for nothing and you get a clean cinematic look. The camera holds one framing unless you ask it to move, so write "slow push in" if you want one. For a scene that builds, write the beats with timestamps, like "[0-6s] the rain picks up. [6-12s] a train crosses the far bridge.", and they play in that order inside one continuous shot.
The music works the same way. Name a genre and that's the genre you get, from lofi to medieval tavern folk to metal, and the same goes for instruments, tempo and mood. Name nothing and you get calm instrumental lofi. Write the sounds of the place as well, the steady rain or the crackling fire or the murmur of a cafe. Ask for an artist like Nujabes and you get the flavour, jazzy and dusty and sample-chopped, never the name itself.
The song's shape is chosen for you unless you write it yourself. Section tags like "[Intro] soft rain and keys. [Chorus] the drums come in." reach every track word for word, in the order you wrote them. You can give times instead, like "[0:00 - 0:20] a single piano", as long as at least one named tag is in there with them.
Whether there's a voice is set by the Music control, not by your words. On Instrumental, the default, asking for humming won't get you humming, because a vocal word is read as mood and dropped. How closely the rest is followed is set by Direction: leave it On and the gaps you left get filled with choices that fit the genre, turn it Off and your brief is followed exactly. Either way, what you rule out stays out, so "no drums" means no drums. Choose how closely Chillframe follows your brief has more on that control.
One thing a brief can't do: text, signage, logos and watermarks are kept out of the picture, so a title card or a channel logo won't arrive. If the box is blank and you're stuck, open a preset and its full brief lands in the composer for you to edit. Typing @ lets you point at up to 8 images, videos or tracks from your Library: an image sets the opening frame, a video seeds the motion, a track sets the style the music is written in. Anything else, email [email protected] and a human will read it.
