I recommend Hitfilm Express to the stop motion communities that I belong to. There are a lot of young people creating fantastic content with limited budget. They would be a good audience for Hitfilm Express and potential upgraders to Hitfilm Pro when their situation changes.
Here's the thing
1) Many of them are using mobile devices rather than PC.
2) Those using PC have lower end machines.
I have found with my own machine that it runs HF4 well but HF12 just demands a little too much.
I know there has been a request for a mobile version of HF but what about a HF Express lite version?
