Need to know what kind of PC, how fast, how much RAM…
Also, which version on PowerPoint…
In general, if you can export an MPEG1 file, PowerPoint will play it back, but it’s only half-size, 320×240.
Newer versions of PowerPoint LOVE Windows Media files. You can export them from FCP by purchasing a third party compression codec from popwire.com or flip4mac.com and installing it on the Mac running FCP.
But be sure to test, test, test!! Leaking RAM and embedded video files have caused many a PC to crash during a PowerPoint oresentation,
Make sure the PC is up to the task. Video in a PowerPoint presentation generally asking a lot of any PC that is more than perhaps three years old.
