AI Voiceover
Definition
Narration spoken by a model instead of a person. You hand it text, it hands back audio with pacing, emphasis, and breath in roughly the right places. Good enough on a 30-second clip that most listeners never think about it, and cheap enough that you can redo the take forty times.
Two classes of engine are in play and the gap between them is mostly money.
The standard class runs a fast, efficient model, and it is what free and Starter accounts render with. The read comes back clean and slightly flat. It handles declarative narration well and comedy badly.
The premium class is the default on Pro and Studio. Generating it costs real money per character, which is why Orange charges a small per-scene surcharge rather than folding it invisibly into the base price. That is the whole premium, and a paid account can switch it off per video and spend the credits on more videos instead. The exact figure sits on the pricing page.
Language coverage is where synthetic voice genuinely beats booking a person. Orange ships 34 languages and the same script can be spoken in every one of them for the cost of the renders. Getting 34 native reads out of human talent is a project with a producer attached to it.
The failure mode nobody warns you about is emphasis. A model reads the words rather than your intent, so a line whose meaning depends on which syllable carries the stress will land wrong about as often as it lands right. A better voice does not fix that. A rewrite does: build the emphasis into the sentence structure so the read cannot miss it. Short clauses. Important word last.
For anything past two minutes, or anything with a character in it, a human is still better and it is not close.

The first one to three seconds, which is the whole audition. A viewer decides to stay or swipe before your second sentence lands, so the hook has to carry a promise the rest of the video pays off. Everything downstream inherits whatever audience the hook managed to keep.
CTA (Call-to-Action) in VideoThe line that tells a viewer what to do next. Follow, comment, tap the link, or buy. It usually lives in the last three to five seconds, and it works better when the ask is small and specific than when it is broad and polite.
AI Subtitle GenerationCaptions written and timed by software instead of typed by hand. There are two ways to get them: transcribe the audio, or take the text you already wrote and align it to the voice track. The second way cannot misspell a name, because it never guesses at what was said.
AI Music GenerationOriginal background music composed on demand, to a mood and an exact length. You describe the feel and the runtime, a model writes the track. Nothing is licensed from a library, so nothing gets claimed, and a 34-second video gets 34 seconds of music instead of a fade at 30.
