Asterion Join Beta For the filmmaking middle class.
Practical AI tools made by a working filmmaker, built around deadlines, not demos.
// Why I built this
My frustration with AI tools wasn’t that they were AI. Any tool, AI or otherwise, lives or dies on its usefulness in the edit. I have cut shots out of an edit I planned for days and shot for hours. What killed these tools was simpler: they kept pulling me out of Premiere. Export, go somewhere else, wait, and re-import. The round trip killed the momentum.
Temp VO is a good example. Scratch narration sounds fine AI-generated, good enough for a rough cut. But the workflow was: leave Premiere, go to a cloud tool, build the VO, download the file, then figure out what landed where and start reorganizing, housekeeping instead of editing. There was no way to just do it inside Premiere. So I started building a panel that could.
One experiment led to another. That became Asterion. Not a vision for the future of filmmaking, just what happened when a working editor got annoyed enough to start building.
// Asterion Generate
Asterion Generate is the Premiere Pro workflow layer for model routing, prompts, previews, libraries, and import. Each tab supports a different part of the same post-production loop: source material, generated options, voice, sync, results, and setup.
// Asterion Generate
Load a selected Premiere clip, attach reference frames, shape the prompt, and keep results in a library instead of another download folder. Selected outputs can be brought back into the Premiere project bin when they are ready.
// Models
Asterion Generate starts with practical fal.ai and Atlas Cloud routes for Seedance, Kling, Wan, LTX, Hailuo, Vidu, Seedream, Imagen, Flux, and Qwen, with Kokoro and ElevenLabs covering voice and sync work.
// Voice
Use local voice for private drafts, cloud voice for client-ready options, then keep the audio tied to the same post pipeline.
// Sync
Sync is where dialogue replacement, localization tests, and consent-gated clone workflows stay reviewable before anything lands back in the edit.
// Library
Generated shots, voice files, and sync outputs need a place to live. Asterion treats the library as part of the workflow, not an afterthought.
// Settings
Editors should know what is connected, where files are going, and which workflow settings are active before they run a job.
// Workflow
Start from a selected clip, a reference image, transcript context, or the property already selected in a host app.
Run the focused tool: generation, voice, sync, story search, paper-cut drafting, or expression authoring.
Outputs stay visible and explicit so editors can inspect, copy, favorite, import, or discard.
// Companion plugins
Asterion Assistant and Asterion Expressions extend the same product family into story-aware editorial support and motion-design utility.
Premiere Pro plugin / Beta track
Editor-controlled story intelligence inside Premiere: attached timeline context, transcript search, evidence-linked notes, paper cuts, and rough-cut preparation.
After Effects plugin / Beta panel
Plain-language After Effects expressions for selected properties: generate, review, copy, favorite, and apply without leaving the project.
// FAQ
No. Asterion is a focused AI post-production workflow tool for generation, voice, and lipsync.
No. Asterion is designed to work with Premiere Pro workflows, not replace the editor.
Cloud generation is handled through explicit review steps so editors can see the selected workflow, estimate, and output path before running a job.
// Early access
Asterion is for editors, filmmakers, agencies, and post-production creators who want practical AI workflows without turning every decision into a browser-tab handoff.
