AI Text to Video: Turn Simple Prompts into Scroll-Stopping Clips

Article

Short video is where attention lives now.

TikTok, Reels, YouTube Shorts, X videos - everyone knows they should be posting more, but actually producing decent clips every day is hard:

  • You do not have time to shoot and edit.
  • You are not an After Effects wizard.
  • Ideas come faster than you can turn them into content.

This is exactly where AI text-to-video becomes unfair leverage.

In this guide, we will show you how to turn simple prompts into short, scroll-stopping videos using the Text to Video tool in Synpix. We will cover:

  • What AI text-to-video actually does (and does not do)
  • A step-by-step walkthrough inside Synpix
  • Battle-tested prompt recipes for different use cases
  • How to chain text-to-video with image-to-video and the gallery for faster workflows

What is AI Text-to-Video?

AI text-to-video is a model that takes a text description of a scene and generates a short video clip (usually 5-8 seconds).

You give it

  • What should be in the scene
  • How the camera should move
  • What style or mood you want

The model handles

  • Composition and motion
  • Lighting and camera movement
  • Consistent frames from start to finish

In Synpix, text-to-video is designed to be:

  • Short-form first - perfect for hooks, intros, and B-roll
  • Prompt-driven - you control the outcome with clear instructions
  • Credits-based - you always know how much a video costs to generate

If you already use image generation, think of text-to-video as cinematic images that move.

Where Text-to-Video is Actually Useful

Instead of trying to generate entire movies, focus on high-value, short assets:

  • TikTok / Reels hooks

    A 5-second visual hook that plays under your voiceover.

  • Product B-roll

    Abstract, cinematic loops to pair with your product screenshots or UI.

  • Channel intros and transitions

    Logo reveals, glitchy scene transitions, branded interludes.

  • Mood / story beats

    A few seconds of scenery to bridge between talking-head sections.

The pattern is simple:

Film (or record) the human part → Use Synpix to generate short visual clips → Edit them together.

Step-by-Step: Generating Your First Text-to-Video in Synpix

Or go directly to the app workspace: /en/app/text-to-video

  1. Describe the scene clearly

    In the prompt field, describe:

    • The main subject
    • The action or motion
    • The style or vibe
    • The camera movement (if important)
    Example prompt

    A cyberpunk alley at night, neon signs flickering in the rain. The camera slowly pushes forward through light fog, with puddles reflecting the colors. Cinematic, 24fps, moody, sharp details.

    This is much stronger than just "cyberpunk city video".

  2. Choose duration and aspect ratio

    Synpix text-to-video is optimized for short clips in the 5-8 second range.

    • 5 seconds - great for fast hooks and transitions
    • 8 seconds - better for looping backgrounds or longer shots

    Match the aspect ratio to your platform:

    • 9:16 - TikTok, Reels, Shorts
    • 16:9 - YouTube videos, desktop
    • 1:1 - Square feeds, some ad placements
  3. Generate and review

    Hit Generate and let the model do its thing. When the clip is ready, you will see:

    • A preview player
    • Basic metadata (duration, aspect ratio, model)
    • The original prompt (so you can tweak and re-run)

    If you are logged in, successful generations are saved into your Gallery, so you can:

    • Re-watch and reuse
    • Share the public link
    • Use "Try it yourself" from the gallery to iterate on the same idea
  4. Iterate with small prompt changes

    The fastest way to get something you like is to keep the core idea the same and change one thing:

    • Camera
    • Style
    • Time of day
    • Movement
    Example set

    Original:

    A magical forest at dawn, fireflies glowing between the trees, the camera slowly glides forward. Soft cinematic lighting, 4K, dreamy.

    Variations:

    • ... the camera orbits slowly around a single glowing tree.
    • ... with a gentle handheld camera shake, like a fantasy documentary.
    • ... at night, with a bright moon casting sharp shadows.

Prompt Recipes for Common Use Cases

Product / SaaS B-roll

Use this when you want abstract motion behind UI screenshots or text overlays.

Abstract 3D shapes slowly rotating in a clean studio environment, soft gradients in the brand colors (blue and purple), subtle camera dolly movement, shallow depth of field, 4K, smooth and modern, perfect as background b-roll.

Pair this with your UI screen recordings in your editor.

TikTok / Reels Hook

Use visual storytelling to set up your video's first sentence.

A person standing on a rooftop at sunrise, city skyline in the background, the camera slowly moves from behind their shoulder towards the sky, birds flying across the frame, cinematic, inspirational, warm color grading.

Record your hook line as voiceover and put this clip underneath.

Logo / Brand Reveal

For intros, outros, or transitions.

Dark background, glowing particles slowly swirling toward the center of the frame. As they collide, they form a bright flash that reveals a simple white logo outline, then the particles fade out. Cinematic lighting, slow motion, high detail.

Later you can composite your actual logo over the bright flash.

Pro Tips for Better AI Text-to-Video Results

  1. Be specific about motion

    The model is sensitive to motion instructions. Pick one and state it clearly:

    • Camera slowly pushes forward
    • Camera orbits around the subject
    • Static camera, only the subject moves
  2. Style + mood are a combo

    Instead of just saying "cinematic", combine:

    • Genre: sci-fi, fantasy, documentary, commercial
    • Mood: moody, uplifting, tense, dreamy
    • Technical: 24fps, 4K, anamorphic bokeh, film grain

    Example: A futuristic city street, rainy night, the camera moves behind a person walking with an umbrella. Neon reflections, moody, cinematic, 24fps, subtle film grain.

  3. Think "clip", not "movie"

    Short, self-contained moments work best:

    • One location
    • One action
    • One mood

    You can always generate multiple clips and edit them into a longer sequence later.

How Text-to-Video Fits into the Rest of Synpix

Text-to-video is just one piece of the Synpix workflow. You can combine it with:

  • Image to Video - upload a still image and animate it into a dynamic shot.
  • Image tools - design your key frame first, then animate it.
  • Gallery - reuse and remix your best clips, or share public links.

Typical workflow:

  1. Use the Image Generator to design a strong still frame.
  2. Use Image to Video to animate that frame.
  3. Use Text to Video to create extra B-roll and transitions.
  4. Export and edit everything together in your favorite editor.

Every generation you like can be kept public in your gallery to build a personal library of reusable assets.

Try It Yourself

The fastest way to learn text-to-video is to generate three clips right now:

  1. A product B-roll for something you actually sell or use.
  2. A hook shot that matches your next TikTok or Reel idea.
  3. A logo or brand reveal clip.
