iPads are overpriced toys, best for web surfing, watching videos and playing light games.
For getting some work done, go with Microsoft Surface Pro tablets, they run a real business-class operating system.
...this forum is for Premium Pro , which is a professional video editing program that is engineered for use with adequate hardware to run the program. An IPad or tablet generally has no where near the capability to run this program suitably. Use the IPad,or, tablet in the manner it was INTENDED to be used........as a PING PONG mallet !!!
