Finding signal on Twitter is more difficult than it used to be. We curate the best tweets on topics like AI, startups, and product development every weekday so you can focus on what matters.
Everything below is free and open: the plugin, the installers, and the full prompt library. The only thing you pay for is generation itself, billed per second through the LTX API.
How It Works
The workflow is simple:
Select an image layer in the timeline
Launch the plugin
Write a motion prompt
Click Generate
The video appears in your composition, placed above the original layer
How it changes your work
Most of the time spent on image-to-video was in the manual back-and-forth.
This plugin removes that overhead.
Instead of losing up to 12–15 minutes on every test, you stay inside After Effects and keep working.
How to set it up
Requirements:
Adobe After Effects 2024 or newer
LTX account + API key (needed for API gen - the plugin itself is free).
Register here: amirmushich.link/AMIR-LTX
Installation:
Windows:
Run the CEP installer and restart After Effects — full steps: github.com/amirmushichge/LTX_FrameFlow
macOS:
Run the ScriptUI installer and enable script access in Preferences — full steps: github.com/amirmushichge/LTX_FrameFlow
After installation, open the plugin via
Using the Plugin
Every control is labeled on the screenshot below — save it as your quick reference.
Settings / API Key
paste and save your LTX API key (stored locally only)
Source Layer
confirms a still image layer is selected in the timeline (not just the Project panel)
Prompt Field
your motion instruction
Duration / FPS / Engine
clip setup; the cost estimate updates live
Generate Video
starts the job; the MP4 lands back in your Ae project when done
Output and Status
Import Above keeps the source and adds the MP4 above it, Hide Source replaces it; status shows Ready, Generating, or Error
Start small. Longer clips cost more time and credits.

Prompting Principles for LTX-2.3
(Image-to-Video)
LTX-2.3 responds best to full, flowing sentences written like a cinematographer's shot description - not a list of disconnected keywords. Three rules made every prompt above work:
Write one flowing sentence with verbs, not a list of keywords:
“the camera slowly pushes in as the subject turns” beats “push in, subject turns, cinematic.”
Order matters: action first, camera and lighting last.
Run the same prompt 2–3 times before rewriting it:
LTX-2.3 has some run-to-run variance; a “bad” first result doesn't always mean a bad prompt.

Final Thought
Staying inside professional video software while generating footages is the creative energy booster.
Every minute you don't spend exporting, uploading, and reimporting is a minute spent actually iterating on the shot. These iterations are what brings you closer to a “great” and “commercial” output.
Install the FrameFlow plugin, run your first generation, then go create something game-changing for your clients (or your feed).
