what ffmpect command did you use in the end?
## Assistant
## Assistant
The final ffmpeg command I used was:
```bash
ffmpeg -i "openclaw-with-cerebras.mov" -filter:v "crop=1400:2150:520:160" -c:a copy "openclaw-with-cerebras-cropped.mov" -y
```
This crops the video with:
- **Width**: 1400 pixels
- **Height**: 2150 pixels
- **X position**: 520 (starting from left)
- **Y position**: 160 (starting from top)
- **Audio**: copied without re-encoding (`-c:a copy`)
- **-y**: overwrites the output file if it exists
