LogInAI lighting is reaching new heights.
AI relighting is a very useful feature available in several programs, including SwitchLight by Beeble – a tool that can "composite your images with optimal lighting and backgrounds." Its latest update allows you to relight videos, and it looks awesome.
There are some videos on the internet already, and you can see how the lighting shifts dynamically together with the person.
You can upload HDRIs or copy lighting from a reference portrait – SwitchLight will extract the light information, recreating an accurate effect for the image, and the result will be impressive either way. There are also presets if you don't have any particularly creative ideas.
SwitchLight detects the people and objects in the background automatically and cuts them out. It creates PBR maps (Albedo, Normal, Roughness, and Specular) so you can use them in any 3D software, including Blender and Unreal Engine.
While it may not always be 100% accurate, you can't argue that the tool does its job really well and, perhaps more importantly, easily and quickly.
If you're interested in other relighting software, check out ClipDrop, NVIDIA's RANA for avatars, and this research, which enables the effect using a webcam.
