i wanted to ask about a certain scene in this music video, it starts at about 1:36. how would you go about achieving that glowing white background, that bleeds over onto the subject? im assuming that if this is possible to recreate with VFX then it would be AE? does anyone have any insight?
thanks for reading! looking forward to any replies!
There's three ways to do this. The first is to shoot with a lot of backlight on a white stage and use diffusion on the lens. The second is to shoot on greenscreen and add your own background, which is probably what was done here. The last option is to shoot normally and then rotoscope the people to separate them from the background. With all the techniques the lighting is the most important part. In this case backlight. Lots of backlighting. Lots.
If this is done in post the first step is to separate the actor from the background. Depending on how you've shot your footage look up Keying or Rotoscope. You can find tutorials buy typing those terms in the AE Search Help field at the top right corner of AE.
Once the actor or actors are separated from the background you put a white layer behind them. Depending on how good the lighting is you may have to add a little light wrap (another good thing to search for right from AE. You may even need to add a lens flair or other lighting effect to help with your light wrap.
The next is to duplicate the layer with the actor, blur the top copy, and set the blend mode to screen or add. The opacity of the blurred layer is then adjusted to complete the look. If the footage is shot backlit in the first place and the background is light you can achieve this look by simply duplicating the footage, bluring the top copy and setting the blend mode to Add. For this kind of compositing it's always best to set AE's project color depth to 32 bit. A little fooling around with an I stock photo using these techniques you can go from this:
