SAM Audio

Seedance 1.5 Pro is a next-generation AI audio-video generation model developed by ByteDance’s Seed research team that produces native, synchronized video and sound in a single unified pass from text prompts and image or visual inputs, eliminating the traditional need to create visuals first and add audio later. It features joint audio-visual generation with highly accurate lip-sync and motion alignment, supporting multilingual audio and spatial sound effects that match the visuals for immersive storytelling and dialogue, and it maintains visual consistency and cinematic motion across multi-shot sequences including camera moves and narrative continuity. Able to generate short clips (typically 4–12 seconds) in up to 1080p quality with expressive motion, stable aesthetics, and optional first- and last-frame control, the model works for both text-to-video and image-to-video workflows so creators can animate static images or build full cinematic sequences with coherent narrative flow.

No production is complete without sound design. Visually intuitive and stocked with tools and effects to master your production, AudioDirector is the comprehensive audio workstation for multi-tracking, mixing, editing and sound restoration. Export your entire audio project from AudioDirector directly into PowerDirector and vice versa. Your audio and video project edits synchronize perfectly between the two apps. Let powerful AI tools create the perfect recording environment, anywhere. Remove wind gusts, reverb, and echo from audio clips intelligently so dialogue and ambient sounds are clearly heard. Throw your vocals through professional tone filters – or create your own. Instantly fix pitch issues and achieve perfect intonation. Want to use a music track without the distracting vocals? Extract pristine instrumental tracks from your favorite songs. Get the most out of your mix with complete track control and comparison. Combine and apply multiple effects at the same time.
