I'm not a pro photographer, however, I would have thought that using a greenscreen or other process that provides better contrast and colour separation.
You could purchase the product used in the video. Difference blend mode would be the obvious choice as a start point to make a mask from two shots. I imagine that any shadows created by the product would cause issues, even with diffuse lighting etc.
Green is not a good background color for being removed in still images green spill and possible green color cast is not easy to deal with. A gray or black black background should be easier to remover then White of White. You need good contrast for background removal. Adobe Object selection is getting better but white on white will be difficult for it. Lighting the object an background separately is important taking you product shots. The should be good information one the web about taking product shots. You video is not using Photoshop its special application designed for product photos sithe tools disign for resolving edges.
