I'm looking at buying some LED lights to help with real estate interior video while using an X5 and DJI Osmo. All suggestions welcome. How many do I need to illuminate an average room?
I would encourage you to hold off on buying LED lights for shooting interior video because the top interior videographers do not use LED lights to shoot interiors.
As an example, this is an interior video done by Zoltan Prepszent with a DJI OSMO. Here is a post I did on the PFRE blog a couple of years ago where Zoltan explains why he was forced to shoot with the DJI OSMO. This is one of my all-time favorite property videos!
Also, I recommend Grant Johnston's video series on "Using the DJI Osmo to Shoot Professional Real Estate Video".
