Superior Cinematic Texture

Prompts:

A close-up of a battle-worn soldier in bright daylight, dirt and scratches on his face, wearing tactical gear. He grips his weapon tightly, breathing heavily, sweat glistening on his skin.

Camera: static medium close-up, keeping the soldier's face and weapon clear in frame with high exposure, no dark shadows. Mood: tense, urgent, cinematic realism.

<S>We don't have much time! Stay sharp!</S>

<AUDCAP>Heavy breathing, distant gunfire echoing, faint radio static, low rumble of explosions far away</AUDCAP>

Real Human Vocal Texture

This video will blow your mind! It’s absolutely like a real human.

Prompts:

A bearded man wearing large dark sunglasses and a blue patterned cardigan sits in a studio, actively speaking into a large, suspended microphone. He has headphones on and gestures with his hands, displaying rings on his fingers. Behind him, a wall is covered with red, textured sound-dampening foam on the left, and a white banner on the right features the "CHOICE FM" logo and various social media handles like "@ilovechoicefm" with "RALEIGH" below it. The man intently addresses the microphone, articulating, 

<S>is talent. It's all about authenticity. You gotta be who you really are, especially if you're working</S>. 

He leans forward slightly as he speaks, maintaining a serious expression behind his sunglasses.
