TensorSharp adds a local video studio: LTX 2.5 image-to-video, timeline editing, MP4 export
fuzhongkai · reddit · 2026-10-19
The maintainer of TensorSharp, an open-source local inference engine and agent runtime, added a Video Studio for generating footage locally and assembling it into an editable project — no cloud account needed (media processing and MP4 export run through local FFmpeg). The demo runs on a MacBook Pro M5 Pro with 48GB via TensorAgent.
Demo flow: a still image seeds an LTX 2.5 Distilled GGUF generation (1024×1024, 145 frames at 24fps ≈ 6s, 11 denoising steps, audio enabled), taking 13m15s; the clip joins a timeline with the original image as a 5-second ending, rendering an 11.04s composition.
Key features:
- Generated takes stay in an asset library for multi-take shot selection;
- Timeline with multi-track video/audio, trimming, splitting, volume, fades, autosave, undo/redo;
- Chain shots by conditioning on a clip's final frame — though appearance/motion can drift and audio doesn't carry across joins;
- Supports LTX 2.5, MiniMax-H3, and Wan 2.1/2.2 checkpoints with first/last frame, timed keyframes, and reference images;
- Optional local LLM assistant proposes timeline edits and shot plans, applied only after review.
He asks what the community needs most: shot continuity, take management, or final-edit tooling.
