Pro Tips
Background Color
You can choose any solid color to replace your original background. Green is recommended for users who plan to use chroma key effects in post-production, but any color can be used depending on your workflow.
Container / Codec
For best compatibility and performance, choose MP4 with H.264. This format works across most editing software, social platforms, and media players.
Single Subject
For best results choose an image with a clear primary subject. Scenes with multiple subjects may confuse the model producing substandard results.

Contrast, Lighting and Clothes
For best results even lighting helps the AI differentiate foreground and background. Make sure the clothing doesn't blend with the background. And ensure there is contrast between the subject and background.
