Question 1

How does text-to-video generation work?

Accepted Answer

Three steps: 1) describe your idea in any language; 2) AI enhances the prompt and translates it into English when the model works better with it; 3) pick one of 19 models (Gemini Omni, Veo 3.1, Kling 3.0, Seedance 2.5, MiniMax H3, WAN 3.0, HappyHorse 1.0, Grok Imagine and more) and get your video, usually in 2–10 minutes. You can edit the prompt at any stage.

Question 2

What is the difference between AI video models?

Accepted Answer

Seedance 2.5 is ByteDance's flagship: up to 30 seconds in one pass, with up to 30 photos + 10 videos + 10 audio files as references. Seedance 2.0 — 4–15 seconds, best-in-class character consistency, stereo sound. Gemini Omni by Google — 4–10 seconds up to 4K, up to 7 images, native sound with lip-sync. Veo 3.1 by Google — 8 seconds with extension up to 3 minutes, 720p–4K, Lite/Fast/Quality modes. Kling 3.0 by Kuaishou — 3–15 seconds, Elements 3.0 for keeping the same characters, multi-shot scenes. MiniMax H3 (Hailuo 3.0) — native 2K with stereo sound in one pass and video editing by text. HappyHorse 1.0 by Alibaba — cinematic picture, T2V/I2V/R2V/Video-Edit modes. WAN 3.0 — up to 30 seconds, video from a document or link. WAN 2.7 — video editing and references. LTX-2 — up to 4K at 50 FPS. PixVerse V6 — an affordable all-rounder with video continuation. Grok Imagine — fast 6–30-second clips; Grok Imagine 1.5 — realistic photo animation with sound. Kling Motion transfers motion from a video onto a photo, and Kling Avatar makes a talking video from a photo and audio.

Question 3

Question 4

How much does AI video generation cost? Is there a free version?

Accepted Answer

You get 35 free credits on sign-up (1 credit = 1 RUB) to spend on any model. There is no subscription: you pay only for generations, and most video models are billed per second. If a generation fails, the credits are refunded automatically. Images in Flux 2 Klein, Flux 1 Schnell and SDXL Lightning are free within a daily limit. Current prices are on the pricing page.

Question 5

What video formats and resolutions are available?

Accepted Answer

Aspect ratios: 9:16 (Reels, TikTok, Shorts), 16:9 (YouTube), 1:1, plus 21:9 and others on some models. Resolution: 480p to 1080p, native 2K on MiniMax H3, 4K on Veo 3.1, Gemini Omni and LTX-2. Duration: Seedance 2.5 and WAN 3.0 — up to 30 seconds, Grok Imagine — 6–30 seconds, Kling 3.0, Seedance 2.0, HappyHorse 1.0, MiniMax H3 and WAN 2.7 — up to 15 seconds, LTX-2 — up to 20 seconds, Gemini Omni — 4–10 seconds, Veo 3.1 — 8 seconds with extension up to 3 minutes, Kling Motion — 3–30 seconds, Kling Avatar — up to 5 minutes.

Question 6

What is Kling Motion and how does motion transfer work?

Accepted Answer

Kling Motion transfers motion from a video onto a photo. Upload a photo of a character and a video with the movement, and AI creates a clip where the character from the photo moves like the one in the reference video: dancing, gesturing, repeating choreography. Length is 3 to 30 seconds, quality 720p or 1080p, billed per second.

Question 7

How do I animate an image or transfer motion?

Accepted Answer

All 19 video models accept an image: upload a picture or photo, describe the movement, and AI brings it to life. For a realistic portrait with sound, use Grok Imagine 1.5 or Kling 3.0. Kling Motion transfers moves from another video onto the character in your photo (a dance, gestures), and Kling Avatar makes a portrait speak over your audio with lip-sync.

Question 8

Can I make a talking avatar from a photo?

Accepted Answer

Yes, with Kling Avatar: upload a portrait and a ready-made voiceover, and the model syncs the lips and facial expressions to the speech. The video is as long as the audio, up to 5 minutes; quality is Standard 720p or Pro 1080p. Great for narrators, greetings, explainer videos and virtual presenters.

Question 9

Can I edit an existing video?

Accepted Answer

Yes. WAN 2.7, HappyHorse 1.0 and MiniMax H3 change an uploaded clip from a text instruction while keeping the original motion. WAN 2.6 restyles video, PixVerse V6 continues it, and Gemini Omni, Seedance 2.5/2.0 and WAN 3.0 use a video as a reference for a new clip. The result can be upscaled to 4K with the built-in AI upscaler.

Question 10

Can I use the videos commercially?

Accepted Answer

Yes: ads, monetized YouTube, Instagram, TikTok, Reels, commercial projects and courses. The service claims no rights to the videos you create — no extra licenses are needed, and there are no watermarks.

Question 11

Does the AI generate sound?

Accepted Answer

Yes, most models create sound together with the video: music, effects, ambience and speech with lip-sync. Native sound is available in Gemini Omni, Veo 3.1, Seedance 2.5, Seedance 2.0, MiniMax H3, HappyHorse 1.0, WAN 3.0, WAN 2.6, Kling 3.0 and Grok Imagine 1.5. Seedance 1.5 Pro supports lip-sync in 7 languages.

Question 12

Do I need video editing skills?

Accepted Answer

No! Sixio is a video generator that needs no editing. Describe your idea in plain words, choose a model and click "Create" — the AI builds the composition, camera movement, lighting and sound for you. Not sure which model to pick? The AI assistant will choose one for your task.

Question 13

Can I generate images? Which models are available?

Accepted Answer

Yes, the gallery has 19 image models: GPT Image 2.5, GPT Image 2, GPT Image 1.5, Nano Banana 2, Nano Banana Pro, SeDream 5 Pro, SeDream 4.5, Flux 2 Pro, Grok Imagine 2.0, Qwen-Image 2.1, Qwen2, Z-Image and more. Flux 2 Klein, Flux 1 Schnell and SDXL Lightning are free within a daily limit. You can also edit images with references, edit just a painted area with a mask, reframe them to a new aspect ratio, split them into layers, upscale them and remove backgrounds. A finished picture can be animated in any video model right away.

Question 14

How does music generation work in Sixio?

Accepted Answer

Music is created with Suno V6, V6 Mini and V6 Wild. Make a song from text, set its length and variety, or create a track from video, audio and image references. Add vocals to an instrumental or instruments to vocals, make mashups, covers, extensions and sound effects. You can extend a finished track, replace a section, split it into stems, download WAV, sync lyrics for karaoke and .lrc, turn it into an MP4 music video or export MIDI.

Question 15

Can I master a track?

Accepted Answer

Yes. Mastering balances the frequencies and dynamics, brings loudness to streaming standards and protects against clipping. You get two 24-bit FLAC files and a free release pack: 16-bit / 44.1 kHz WAV, 320 kbps MP3 and a 3000×3000 cover. You can master a track made in Sixio or upload your own.
