Muzaic.ai is a browser-based tool that scores video automatically. You give it a cut (or a folder of cuts); it returns a finished audio mix — music, SFX, ambience and voiceover as separate layers — mastered to broadcast spec, in roughly 30 seconds per clip.
What it actually does
The pipeline runs in four stages. First it analyses the video: scenes, objects, pacing, colour and sentiment. From that it builds an audio plan and commits each concept to a clear direction (the site's example: a string quartet under a battle scene) rather than averaging toward something inoffensive. Then it composes every layer to fit the picture and the other layers — SFX land on the action, ambience ducks under speech, the voiceover is drafted from your brief rather than read out. Finally it mixes and masters the result. Existing audio in the source can be kept, replaced or mixed under.
Output is three concepts per clip, exported as MP3 or WAV. Layer balance is adjusted inside Muzaic before export; the deliverable is the finished mix, not separate stems.
The commercial angle
Pricing is metered in minutes of finished audio, not per track or per download; downloads are unlimited. Personal is free for 10 minutes a month, non-commercial only. Creator ($45/month) covers your own brand and paid ads. Studio ($249/month) is for agencies: the licence travels to the client and the legal cover extends to them too. Enterprise adds TV, radio, cinema and OOH, plus a custom contract, DPA and SLA.
What it is not
It is not a music-generation toy. The free tier exists to test the workflow on your own footage; nothing from it may be published. The target user is a team producing hundreds of ad variants a month, where the audio step is the bottleneck.

3Q is an API-first video infrastructure for developers and engineering teams who want direct control over their media backend. A REST video API and native player SDKs give you programmatic access to hosting, ingestion, encoding, live streaming, video-on-demand, and delivery, so you can build video portals, streaming apps, or OTT backends on a single European platform.
The stack is transparent by design. 3Q supports adaptive bitrate streaming over HLS and DASH with mixed HEVC and AVC codecs and automatic Live-to-VoD. Delivery runs over a proprietary global CDN, encryption, and HTTP/2 over TLS 1.3. The Cookie- and Consent-free HTML5 Video Player is barrier-free in accordance with WCAG 2.1/BITV 2.0 and needs no consent layer. Video AI exposes speech-to-text transcription, automatic subtitles, translation, and chapter markers through the same API, and integration fits your existing pipeline and video workflows.
What sets 3Q apart is ownership. 3Q runs on its own independent European video infrastructure, so your data stays in the EU and under German jurisdiction. 3Q is GDPR-compliant and all processes are ISO/IEC 27001 certified, with modular pay-as-you-go pricing and 24/7 support from real video experts.

Kling 4.0
Kling 4.0 is a generative AI video model that combines video generation, multimodal references, audio, storytelling controls, and video editing within a unified creative system. The model supports text-to-video and image-to-video generation along with first and last frames, Omni Reference, and multi-keyframe workflows. Creators can generate videos between 3 and 30 seconds long and define as many as 10 keyframes to control character states, scene changes, and important narrative moments. Output options include 720p, 1080p, and 4K resolutions as well as aspect ratios ranging from 21:9 ultrawide to vertical 9:16. Its Omni Reference system can incorporate up to 15 reference assets using combinations of images, videos, voice references, and defined subjects. Image references can guide characters, layouts, styles, graphics, composition, and story beats, while video references can provide direction for performances, actions, camera movements, and pacing. Kling 4.0 also improves dynamic motion, camera direction, stereo audio, lip synchronization, multilingual speech, and text generation for more complete audiovisual productions. Editing tools enable targeted changes to expressions, body movements, camera positions, backgrounds, visual styles, and other elements without requiring the entire scene to be recreated. Kling AI is also introducing Kling 4.0 Flash as a faster option for frequent generation, with support for text-to-video, image-to-video, Omni Reference, 3- to 20-second clips, and 720p output.
