Help with a presentation (still pictures)

[Swing Coach]

I am giving a presentation on hitting later this month and want to know where to get stills of mlb players so I can use them to illustrate the sequence and commonalities of their swings. I have RV Pro and can use that for some of the illustration...but the video is not very good. Ultimately, I would want to combine both video and stills and save it to a power point. Do I need a GIF animator program and how easy/hard would this be? Any suggestions on how to pull this off would be great. Feel free to IM me on this one.

Thanks,

Ken
