If I have opted for one month subscription and made videos in that period.
will I be allowed to use those videos after one month subscription on social network sites commercially ?(without subscribing further)
But essentially yes you can. The only thing you cannot do without an active subscription is sell any material made in the application to a third party.
I tried to read terms and condition, may be its lengthy or Words used are hard to understand.
can you clarify ?
As, I am going to upload videos made in Videoscribe app to YouTube and monetize it (for that I may use only one month subscription.)
will Videoscribe, Sparkol have any issue/share in published videos on YouTube ?
Depends on what you mean by monetize it. You cannot sell the video to a third party without a subscription. But if it's on a channel on YouTube and you gain revenue from that channel through means other than directly selling your video (advertising, links to other products for example) then that's fine.
