Answers to common questions about video generation
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.

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.
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.
Yes, with Kling Avatar: upload a portrait and audio — a ready recording or a voice-over made right here in the Voice section. 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.
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.
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.
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.

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.
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.
Yes. In the Voice section, paste your text, pick a voice and get a ready mp3 — over 80 languages are supported. You can create your own voice from a live recording or a voice from a description, and dictate the text instead of typing it. The finished voice-over can be used in a talking avatar. The price depends on the length of the text and is shown before you start; if a voice-over fails, credits are refunded automatically.
