+# Render the SquareMCP launch video locally
+
+## Files
+- `render_squaremcp_video.py` renders the video
+- `squaremcp_shotlist.json` drives scene timing and copy
+- `squaremcp_launch_captions.srt` provides burned-in captions
+- `squaremcp_visual_prompts.md` can be used to create optional scene background images
+
+## 1. Install dependencies
+
+```bash
+python -m venv .venv
+source .venv/bin/activate
+pip install -r requirements.txt
+```
+
+## 2. Basic render
+
+Place the script in the same folder as the shotlist and captions, then run:
+
+```bash
+python render_squaremcp_video.py \
+  --shotlist squaremcp_shotlist.json \
+  --captions squaremcp_launch_captions.srt \
+  --output squaremcp_launch.mp4
+```
+
+## 3. Faster draft render
+
+```bash
+python render_squaremcp_video.py \
+  --shotlist squaremcp_shotlist.json \
+  --captions squaremcp_launch_captions.srt \
+  --output squaremcp_launch_draft.mp4 \
+  --draft
+```
+
+## 4. Add your own voiceover
+
+```bash
+python render_squaremcp_video.py \
+  --shotlist squaremcp_shotlist.json \
+  --captions squaremcp_launch_captions.srt \
+  --voiceover founder_voiceover.wav \
+  --output squaremcp_launch_with_vo.mp4
+```
+
+## 5. Optional richer visuals
+
+If you generate background stills for each scene from the prompts, save them in an `assets/` folder like this:
+
+- `assets/scene1.png`
+- `assets/scene2.png`
+- ...
+- `assets/scene7.png`
+
+Then run:
+
+```bash
+python render_squaremcp_video.py \
+  --shotlist squaremcp_shotlist.json \
+  --captions squaremcp_launch_captions.srt \
+  --assets-dir assets \
+  --output squaremcp_launch_with_assets.mp4
+```
+
+## Notes
+- Default output is vertical 1080x1920
+- `--draft` renders 720x1280 and is much faster
+- The renderer creates a clean product-style motion graphic even without scene images
+- If you already have a polished voiceover, attach it with `--voiceover`
