My tablet is a lowly Samsung T290 with a Qualcomm Snapdragon 429 and 2gig RAM.
The 429 is not yet listed on the PD Mobile support page.
Well, something, some update changed either by Samsung, Android, or Cyberlink, thank you.
I now can have THREE overlay video timelines, it is a much more capable and more fun app.
If you were unable to use multiple video layers last time you tried PDM, check again HP Envy Phoenix/4thGen i7-4770(4@3.4GHz~turbo>3.9)
Nvidia GTX 960(4GB)/16GB DDR3/
Canon Vixia HV30/HF-M40/HF-M41/HF-G20/Olympus E-PL5.
