How to create video? Step-by-step guide

1

Write the prompt in your language

Describe what you want to see: "A kitten plays with a ball of yarn at sunset." The more detail, the better the result. You can specify camera style, lighting, and mood.

2

Enhance the prompt with AI

Click “Enhance” and AI will add camera movement, lighting and sound tailored to the selected model. You can edit the result and enhance it again. For models that understand English better, translate the prompt with the “Translate to English” button. Translation to English is free and is a separate button.

3

Pick a model and parameters

Choose a model for your task (see recommendations below). Set the duration (3-30s), resolution (480p-4K) and aspect ratio (9:16, 16:9, 1:1).

4

Generate and download

Click “Create video”. Generation takes 1 to 15 minutes. You can download the finished video, extend it (on some models), upscale it to 4K with AI or add music with the “Soundtrack” button.

Image-to-Video (photo → video)

Upload an image and bring it to life; all 19 models accept photos. For portraits, use Seedance 2.0 or MiniMax H3; for cheap and fast, Grok Imagine 1.5; for a portrait that speaks to audio, Kling Avatar; to repeat movements from a video, Kling Motion.

Video-to-Video (video → video)

Upload a video and change it: edit from a prompt with WAN 2.7, HappyHorse 1.0 or MiniMax H3; restyle with WAN 2.6; continue with PixVerse V6; transfer movement with Kling Motion. Seedance 2.5/2.0, WAN 3.0 and Gemini Omni take a video as a reference for a new clip.

The first frame and references matter most

A model does not invent a video from scratch: it continues your first frame and leans on your references. Composition, lighting, the face, the style and even on-screen text come from there, so almost everything depends on how you prepare them.

🖼️ First frame

  • Match the frame's aspect ratio to the video: 9:16 for Reels and Shorts, 16:9 for YouTube. Otherwise the model will crop the frame or invent the edges.
  • A sharp, high-resolution photo with the face large and unobstructed.
  • Keep only what belongs in the clip: the model will animate extra people, objects and text too.
  • Choose a pose and angle that the movement you want can start from.
  • Put any text for the video on the frame itself: text a model draws on its own often comes out with errors.

You can prepare the frame in the gallery: generate it, change the aspect ratio, fix a detail or text with a mask in Qwen-Image 2.1, remove the background or upscale it. Open Gallery

🧩 References

In our experience, good references make a successful clip about 70% more likely.

  • For a character: 2–3 photos from different angles, one person in each, on a plain background.
  • For a product or object: sharp photos with nothing extra, ideally on a solid background.
  • A video reference sets the movement and camera work; an audio reference sets the voice or music.
  • In the prompt, say what to take from each reference: who it is and what matters in it.

References are accepted by Seedance 2.5/2.0, WAN 3.0, WAN 2.7, MiniMax H3, HappyHorse 1.0, Gemini Omni, PixVerse V6 and Kling 3.0 (Elements).

Quick pick by task

Animate a person's photo

Task

Bring a portrait or photo to life — realistically and with sound.

Why Seedance 2.0

  • One of the best photo-animation models in independent rankings.
  • The face and appearance stay intact through turns and lighting changes.
  • Sound and lip-sync are generated in the same pass.
  • Mini mode is an inexpensive way to experiment.

💡 A strong alternative is MiniMax H3 (from — cr/sec): among the leaders of independent photo-animation rankings, 2K with sound. Cheap and fast: Grok Imagine 1.5 (from — cr/sec). To copy movements from another video, use Kling Motion.

Talking avatar from audio

Task

Bring a photo to life with READY-MADE audio — a presenter, greeting, explainer video or virtual host.

Why Kling Avatar

  • The only model: upload a photo + your audio → a talking video with automatic lip-sync.
  • Up to 5 minutes of speech in any language — synced to the audio.
  • Cheap, per-second: Standard 720p and Pro 1080p.

💡 Need lip-sync from text (without ready-made audio)? — Seedance 2.5/2.0 or MiniMax H3.

Repeat moves from a video

Why Kling Motion

  • Accurately copies motion and timing from the reference video.
  • The character comes from your photo — the face and look are preserved.
  • From 3 to 30 seconds, billed per second.

Task

Take a finished clip and completely change its style.

Why WAN 2.7

  • "Video Editing" mode — recommended for working with finished clips.
  • Preserves the original motion and follows the prompt closely.
  • Supports 720p and 1080p, paid per second.
WAN 2.7 —-— cr/sec

A series with one character

Task

Why Kling 3.0

  • Elements 3.0 keeps characters and objects looking the same across videos.
  • Multi-shot: several shots in one generation.
  • Standard and Pro with sound, Turbo for inexpensive photo animation, 3-15 seconds.
Kling 3.0 —/sec

💡 Seedance 2.5/2.0 also keep a character consistent from references; 2.5 accepts up to 30 photos per request.

Task

Turn a presentation, article or web page into a clip of up to 30 seconds.

Why WAN 3.0

  • The only model that makes videos from a document or link.
  • Up to 30 seconds in one piece, native sound and dialogue.
  • References: up to 10 photos, 5 videos and 5 audio files.

Why Gemini Omni

  • Renders legible on-screen text better than other models.
  • Native 4K (2160p) without upscaling.

Gemini Omni ··· cr.

High resolution on a budget

Task

Shoot a scene with sound in 2K or 4K without paying flagship prices.

Why MiniMax H3

  • Native 2K — the frame is composed in it from the start, with no upscaling.
  • Picture and stereo audio with lip-sync are created in a single pass.
  • Among the leaders of independent photo-animation rankings.
  • Omni reference: up to 9 photos, 3 videos and 3 audio, including voice transfer.
  • An uploaded video can be reworked or continued with a text instruction.
MiniMax H3 —-— cr/sec

💡 Need 4K, or 1080p for even less? Try LTX-2 (from — cr/sec). The picture is beautiful, but it follows the prompt less precisely, so it suits atmospheric scenes and landscapes best.

Creative freedom

Task

Make bold scenes where strict moderation gets in the way.

Why soft-filter models

  • The WAN family (3.0, 2.7, 2.6, 2.6 Flash, 2.5) and MiniMax H3 have virtually no content filters.
  • Seedance 2.0 has reduced moderation with flagship quality.
WAN 3.0 —-— cr/sec

💡 The models from the first point are grouped in the generator picker under the "🔓 Unrestricted models" filter. The service rules still apply.

⏱️ Most models are billed per second: Per-second pricing gives flexibility — pay only for the length you need.

⚡ Quick start

  1. Sign up and get free credits
  2. Try Grok Imagine for your first video
  3. Use "Enhance prompt" for the best result
  4. Make everyday clips on WAN 3.0 and the final version on Seedance 2.5

📝 A good prompt

  • •Describe motion: "camera dollies in"
  • •Specify style: "cinematic", "anime"
  • •Add atmosphere: "sunset", "fog"
  • •Be specific: details matter!

🗣️ Speech in a clip: fitting a line into the video length

  • •A line has to fit into the clip. People speak 2–2.5 words per second: up to 10 words in 5 seconds and up to 20 in 10 seconds, leaving room for pauses.
  • •Is the text longer? Increase the duration or split it across several clips. A line that is too long drifts toward the end: words get slurred and the lips stop matching.
  • •Short phrases sound more natural. Say who is speaking and in what tone: “in a whisper”, “cheerfully”.
  • •Write the line in quotation marks in the language it should be spoken in. When the prompt is translated to English, the quoted text stays as it is, so the character speaks your language.
  • •Speech in languages other than English holds up best in short phrases in close-up.
  • •Need long speech to a ready-made voiceover? Use Kling Avatar: the video lasts as long as the audio, up to 5 minutes.

Frequently asked questions

Which model should a beginner choose?▼

Start with Grok Imagine, the fastest and one of the cheapest models: a 6 to 30 second clip from text or a photo in a couple of minutes. A reliable alternative with sound is Seedance 1.5 Pro. Once you get the hang of it, make your everyday clips on WAN 3.0 and go to Seedance 2.5 or 2.0 for the best result.

Which model is best for top quality?▼

Seedance 2.5 gives the best result. Seedance 2.0 is nearly as good and costs less. WAN 3.0 is a little simpler, but cheaper still, and shoots up to 30 seconds in one take. Gemini Omni delivers native 4K and the best on-screen text, and Kling 3.0 keeps one character consistent across a series of clips.

How do I animate a photo of a person?▼

For the best quality, use Seedance 2.0: the face stays intact through turns and lighting changes, and sound and lip-sync are generated in the same pass. A strong alternative is MiniMax H3: among the leaders of independent photo-animation rankings, 2K with sound. For cheap and fast, use Grok Imagine 1.5. If the character should repeat movements from another video (a dance, gestures), use Kling Motion. If the portrait should speak to a ready-made voiceover, use Kling Avatar. Above all, prepare the photo well: almost the whole result depends on it.

How can I save credits?▼

Make drafts in the same model you will use for the final version, at 480p or in Seedance 2.0's Mini mode, then repeat the prompt that works at 1080p. A prompt tuned for one model may behave differently on another: to move it over, click “Enhance” in the new model's form or ask the AI assistant. For your very first tries, the inexpensive Grok Imagine and Seedance 1.5 Pro are a good fit.

How does pricing work for Kling Motion?▼

Kling Motion is billed per second: ··· credits for each second of video. Clips run from 3 to 30 seconds — you pay only for the length you need.

Which model supports video-to-video?▼

WAN 2.7 (Video Edit mode), HappyHorse 1.0 and MiniMax H3 can edit a finished clip from a prompt while keeping the original motion. WAN 2.6 restyles video, PixVerse V6 continues an uploaded clip, and Kling Motion transfers movement onto a photo. Seedance 2.5/2.0, WAN 3.0 and Gemini Omni take a video as a reference for a new clip.

Which model generates the longest videos?▼

Seedance 2.5, WAN 3.0 and Grok Imagine shoot the longest clips in one pass, up to 30 seconds. Kling Avatar makes a talking video as long as the audio, up to 5 minutes.

What is Seedance 2.5?▼

Seedance 2.5 is ByteDance's flagship: up to 30 seconds in one pass at 480p–1080p, up to 30 photos, 10 videos and 10 audio files as references, timecoded scenes and native stereo audio with lip-sync. Output in MP4 or MOV. It is the best-quality model on the platform and the most expensive one; if 15 seconds is enough, Seedance 2.0 gives nearly the same result for less.

What is Gemini Omni?▼

Gemini Omni is Google's multimodal model: 4–10 seconds in 1080p or native 4K, sound with lip-sync in the same pass, up to 7 images plus a video reference, and prompts up to 20,000 characters. It renders legible on-screen text better than the rest.

What is MiniMax H3?▼

MiniMax H3 is the new generation of Hailuo: 4–15 seconds in 768p or native 2K, with picture and stereo sound with lip-sync generated in one pass. Omni-reference takes up to 9 photos, 3 videos and 3 audio files, and a voice can be carried over from audio. It can rework or continue an uploaded video from a text instruction. It is among the leaders of independent photo-animation rankings and an inexpensive way to get high resolution with sound. A free model with soft content filters.

What is WAN 3.0?▼

WAN 3.0 is Alibaba's new generation: up to 30 seconds in one piece at 480p–1080p, with native sound and dialogue. Four modes: text, frames, references (up to 10 photos, 5 videos and 5 audio files) and video from a document or link — for example, a clip based on a presentation. A model with soft content filters.

What is PixVerse V6?▼

PixVerse V6 is an affordable all-rounder: 3–15 seconds in 360p–1080p. Five modes: text, photo, transition between frames, video continuation and a reference mode with up to 7 named references. Sound is optional, and the model understands non-English prompts without translation.

What's the difference between WAN 2.5 and WAN 2.6?▼

Both are previous-generation models. WAN 2.5 gives a more realistic result but has no sound; WAN 2.6 leans toward a smooth style resembling 3D or cartoons and can restyle an uploaded video. For new clips, WAN 3.0 is the better choice: higher quality, with sound.

What is WAN 2.6 Flash?▼

Flash is the budget version of WAN 2.6 with an even stronger anime/3D bias. It only works with images (image-to-video) but costs much less. Ideal for high-volume cartoon-style content.

What is Seedance 1.5 Pro?▼

What is Kling AI Avatar?▼

Kling AI Avatar by Kuaishou is a talking-avatar model: it brings a portrait to life using uploaded audio with automatic lip-sync, up to 5 minutes. Standard 720p and Pro 1080p.

Ideal for presenters, greetings, explainer videos and virtual hosts driven by a ready-made voiceover.

What is LTX-2?▼

LTX-2 by Lightricks offers native 4K (2160p) without upscaling and 50 FPS, with sound in the same pass. One of the cheapest ways to get 1080p and 4K: the picture is beautiful, but the model follows the prompt less precisely, so it suits atmospheric scenes and landscapes best. Fast (6–20 seconds) and Pro (6–10 seconds) modes.

Which generation modes are supported?▼

Text-to-Video: from a text description. Image-to-Video: animating an image; all models accept it. First and last frame: a smooth transition between two frames (Seedance, PixVerse V6, WAN 3.0, MiniMax H3). References: photos, videos and audio as a model for a new clip (Seedance 2.5/2.0, MiniMax H3, WAN 3.0, HappyHorse 1.0, Gemini Omni).
