⚙️ Customization

SubSpectra is designed to work out of the box, but advanced users can adjust certain internal values and behaviors for finer control.

🛠 Adjustable parameters (manual code change)

These values are currently readonly or hardcoded in the codebase, but you can modify them by editing the source and rebuilding the application.

Variable	Description	Default	Suggested range
video_length	Number of characters hidden in video center pixels	40	1–60
img_length	Number of characters for image hiding	20	8–80
ffmpeg_path	Path to FFmpeg executable	"ffmpeg"	Absolute path or env PATH

🖼 Image filters

The filters in Panel 5 can be extended. To add your own: Navigate to btn_5_start_Click Duplicate a block and implement your custom transformation

🧪 Statistical thresholds

Thresholds that define “OK”, “Suspect”, or “Unnatural” are set in code:

string status = score > 0.9 ? "OK" : score > 0.5 ? "Suspect" : "Unnatural";

Modify these as needed depending on how strict or lenient your detection should be.
