Mirelo SFX
Mirelo SFX is an AI-powered video-to-sound effects solution that brings videos to life with synchronized, realistic audio. Users can generate sound effects, Foley, and ambience that match their footage while preserving dialogue, removing unwanted audio, and keeping sound consistent across cuts. Instead of searching for, trimming, and syncing individual effects, users can upload a video and automatically generate footsteps, impacts, environmental sounds, and other audio elements that land exactly where they should. The model reads visible action, timing, and environment to synchronize sounds with on-screen events. Its speech preservation technology separates dialogue from the original clip and retains it while generating new effects and ambience, allowing users to remove unwanted background music without losing speech. For multi-clip projects, it maintains consistent audio across transitions, making stitched edits sound like one continuous scene.

MiniMax H3
MiniMax H3 is a general-purpose omni-modal generation model that jointly understands multimodal contexts spanning text, images, video, and audio. It generates videos with native stereo sound at up to 2K resolution and 15 seconds in length, delivering content for advertising, branding, ecommerce, product design, UI/UX, gaming, and creative workflows. Users can combine reference types in one instruction, for example, transferring camera movement from a video, placing a character from an image into the scene, and matching vocals from an audio clip, while describing the relationships in natural language. H3 supports text-to-image, text-to-video with jointly generated audio, multi-shot modeling, text-to-audio, and generalized reference and editing across images, videos, and audio. Voice, sound effects, and music are modeled together. The model excels at instruction following, accurate text and brand presentation, and video-to-video motion transfer.

Grok Imagine Video 1.5
Grok Imagine Video 1.5 is xAI’s improved image-to-video model, built for better quality at faster speeds. Now generally available on the Imagine API as grok-imagine-video-1.5, it gives creators and developers a way to start from an image, describe the motion, and choose the resolution and duration for the generated video. Grok Imagine Video 1.5 and Video 1.5 Fast are described as xAI’s best image-to-video models yet, with better motion, better physics, better audio, and faster generation for real creative work. Audio and speech are generated in the same pass as the visuals, so sound effects, ambience, and dialogue land on the action, while speech is clearer and better synchronized. Motion and physics are also improved, helping movement hold together across the length of a clip with fewer warps and more believable weight and momentum. Grok Imagine Video 1.5 Fast almost doubles generation speed, producing 6-second, 720p videos in about 25 seconds.
