How ClipEva Generates, Publishes, and Improves Video
ClipEva is an AI video creation platform with four generation modes: Studio, Narrated Slides, Narrated Chapters, and Interview B-Roll. It also includes AI narration with optional voice cloning, direct publishing to Instagram Reels and YouTube Shorts, and performance analytics that feed back into future scripts. This page is the complete technical reference for how each part works.
Studio: generate a video from one prompt
Studio takes a single prompt and produces a complete short-form video in one pass: an AI-written script, narration in your selected voice and language, a matching visual style, and optional background music, complete with an estimated best time to publish based on your topic and audience.
How Studio works
- Give Eva a topic, concept, or a single rough sentence. A full script is not required to start.
- Studio writes a complete script around what you said, which you can review and edit before anything renders.
- Studio narrates the script in your chosen voice and language, and generates or selects matching visuals.
- Studio suggests a best time to post based on your topic and past performance.
- Nothing publishes without your review and approval.
Studio FAQ
Do I need to write anything, or can I really just describe the idea?
A single sentence is enough to start. Studio expands it into a full script you can then edit or leave as-is.
Can I choose the narrator's voice and language?
Yes, both the narration engine and language are selectable per video, not fixed to one default.
Does Studio pick when I should post?
It suggests a posting time based on your topic and past performance; you decide whether to use it.
Narrated Slides: text-to-video, no camera
Narrated Slides converts text you provide into a narrated video: your script is split into slide-paced segments, narrated in your chosen voice, and paired with visuals per segment, giving a true text-to-video workflow rather than a generic template with your name filled in.
How Narrated Slides works
- Write or paste your script. No images or slides need to exist beforehand.
- Choose whether Eva narrates your exact words, or adjusts them.
- Narrated Slides splits the script into slide-paced segments and generates matching visuals for each one.
- Eva narrates every segment in your chosen voice, with synced word-by-word captions.
- Review and edit the script before export; final video length follows the length of the text you provided.
Narrated Slides FAQ
Do I need slides or images ready before I start?
No, text is the only required input. Visuals are generated to match each segment.
Can I edit the narration script after generating it?
Yes, the full script is editable before you render the final video.
How long can one Narrated Slides video be?
It follows the length of the text you provide: write a short script for a short video, or a longer one for a longer video.
Narrated Chapters: one story, many videos
Narrated Chapters takes one long piece of text or narration and breaks it into several distinct chapter videos, each with its own narration, visuals, and export file, published on its own schedule rather than as segments of a single combined video.
How Narrated Chapters works
- Give it one long story, script, or narration, such as a founder journey, case study, or long-form piece.
- Narrated Chapters analyzes it and proposes where each chapter should start and end.
- Review and adjust the chapter boundaries before export.
- Each chapter is rendered as its own complete, narrated, ready-to-post video, not a teaser for the next one.
- Publish chapters on their own schedule, turning one story into a week of content.
Narrated Chapters FAQ
Does this produce one long video or several shorter ones?
Several separate videos, one per chapter, where each is complete and postable on its own instead of one combined video.
Can I control where one chapter ends and the next begins?
Yes, chapter boundaries are shown before export and can be adjusted.
What's a good source for this, and does it need to already be split into chapters?
No, a single continuous story or script works; the splitting into chapters happens for you automatically.
Interview B-Roll: polish footage you already have
Interview B-Roll takes footage you upload and produces an edited video with B-roll placed against your existing narration or dialogue. You choose and confirm which B-roll clips get used from suggested and your own uploaded options, so the system assists the pairing and never publishes a cut without your review.
How Interview B-Roll works
- Upload interview or talking-head footage you already recorded. No reshoot required.
- Interview B-Roll finds the moments where the topic shifts.
- It suggests supporting B-roll clips for each moment; you can also upload your own footage instead.
- You confirm which clip is used at each moment before the cut is finalized.
- Your original voice recording plays start to finish, unmodified. Only the visuals cut away to B-roll.
Interview B-Roll FAQ
Do I need to shoot anything new for this?
No, it works directly with interview or talking-head footage you already have.
Does it automatically pick which B-roll to use?
It suggests clips to match what's being said; you review and confirm the final selection.
Can I use my own B-roll footage instead of suggested clips?
Yes, you can upload your own B-roll alongside or instead of suggested options.
Voice & narration
Every ClipEva video is narrated automatically. Narration quality and voice options scale with plan: the Free plan narrates with Kokoro and standard voices; Humanoid Voice unlocks ElevenLabs premade voices for more natural, expressive narration; Cloned Voice adds ElevenLabs voice cloning so a video can be narrated in your own voice.
- Free: Kokoro and standard voice narration, available in every creation tool.
- Humanoid Voice: everything in Free, plus ElevenLabs human-like premade voices.
- Cloned Voice: everything in Humanoid Voice, plus ElevenLabs voice cloning to narrate in your own voice.
