assets# Prophetero Loop Lab GLOBAL 0.3
Find repeatable cuts in supported local videos, compare transition styles and inspect the result before exporting. Works with LTX, H3, camera footage and other sources; it is not tied to a generation model.
Start with Recommended: a clean picture cut and independent short sound smoothing. Suggested cuts include first/last frame previews. Fine-tune either endpoint directly on its card with native-frame -1/+1 buttons, or reset to the original suggestion. Manual edits invalidate the earlier score; the other suggestions remain untouched.
Compare transitions opens three configurable preview cards from the same cut and sound settings. Try direct cut, crossfade, black/white dips, left/right wipes, opening iris or blur. Render all three sequentially or one version, inspect three cycles, then explicitly apply your choice. An effect is a visible scene transition, not a guarantee of natural continuous motion.
Picture and sound stay independent. Sound offers follow-video, smoothing, direct cut or mute. Full exports retain recorded source-generation tags where supported and save an adjacent .loop.json processing recipe. Originals remain unchanged; output picture is re-encoded as H.264, not losslessly copied.
Includes a custom node/workflow, installer and eight helper languages (EN default). Local CPU/FFmpeg processing; no AI generation model required. Install into the ComfyUI backend actually used by your application, restart it fully, and load the updated workflow. A JSON import alone does not install the node or dependencies.
Credits: Prophetero provides the workflow integration, controls, installer and review interface. Media processing and effects use [FFmpeg](https://ffmpeg.org/) through [imageio-ffmpeg](https://github.com/imageio/imageio-ffmpeg); stream inspection uses [PyAV](https://github.com/PyAV-Org/PyAV); local web integration uses [aiohttp](https://github.com/aio-libs/aiohttp), hosted by [ComfyUI](https://github.com/Comfy-Org/ComfyUI). Those projects retain their own terms and are not claimed as Prophetero-authored engines. No FFmpeg binary, AI model or Python dependency is bundled. See THIRD_PARTY.md and LICENSE.txt.
Test edition: heuristic point ranking and automated checks do not replace inspecting your own clip, motion and sound before publishing.
