Enhancing a powerpoint presentation video in youtube

Hello, I have uploaded a powerpoint presentation to youtube but the video needs enhancing. 1. The slide with the title "Samples of proposed structural elements" doesn't enter fast enough and when it does, changes to the next slide too soon. 2. Make the music video last till the end of the presentation, and keep playing if left in last slide This project is about creating a video without the above errors and uploading it to youtube. The title of the video will be "Structural Elements of Metal and Plastic" Here's the video as it is right now: <[login to view URL]>
