I got this idea reading about DaVinci Resolve. So the GoPro automatically generates low res shadow files, called LRV files. They're just small MP4 files. I renamed them to match how PowerDirector names its shadow files and put them in the ShadowEditFiles folder, then added my media to a new project.
But it didn't work, PowerDirector still made its own shadow files (with exactly the same names) and overwrote the ones I placed.
So the theory is, PowerDirector will already have the shadow files without needing to render them, saving me hours. Is there a way to do this? Or if CyberLink's reading this, could you add this feature somehow? Thanks.
