Looks like there’s an issue with PDF playback with a random colour change occurring. The source frames are transparent PNG compiled into a PDF using Afinity Publisher and then Acrobat Pro. The result is the same for both files. The layer uses a Chroma Mask FX to remove the background, the colour changes happens if this is on or off. Haven’t spotted this before as I generally use B&W PDFs.
