I can not control the transitions in powerpoint in my file,

Hi,

You should have a look at the timing and speed of your transitions.

Reduce the duration of your transition to make it more faster.

To make your slides move automatically, go to Transitions and under Advance Slide, select After. Next, set the number of seconds or minutes to wait before the next transition starts.

There's the solution I think,

I hope to see helped to solve your problem.
