Based on the limited information available, it appears you can add a drop shadow in DaVinci Resolve's Fusion tab. The referenced YouTube video (title not provided) suggests there are multiple ways to achieve this effect, although one method may be preferred depending on the type of editing being done. The video mentions some users might extensively use the Fusion tab for editing.
Unfortunately, the provided information is insufficient to detail the exact steps or preferred method. A more complete answer would require the specific instructions from the linked video or a similar resource detailing the process within Fusion.
