The screen is black when I launch FiLMiC Pro

If after launching FiLMiC Pro you experience a black preview window, then please work through the following steps until the preview is restored:

1. Open FiLMiC Pro's Settings > Device > Preview Active and make sure this is enabled.

2. Open iOS Settings > Privacy > Camera > FiLMiC Pro and make it is enabled. If it is enabled, please toggle it off and back on again to force it to refresh and see if your preview is restored in FiLMiC Pro.

3. If steps 2 and 3 were unable to resolve the black preview screen then a clean install is recommend.
