```

## Discussion

Discussion Some video formats do not support a significantly higher still image resolution than the streaming camera resolution. Use the isRecommendedForHighResolutionFrameCapturing method on the video format to check if the format is recommended. For passing customized photo settings to this method, obtain a defaultPhotoSettings object from the video format and modify it.
