Powerpoint slides and audio--best way to marry them

i would say insert the audio into the powerpoint

I would use imovie. But you could check in Garageband >preferences > Export and set movie to full quality and uncheck (set artwork to recommended size...)

Like iStevus, if I were doing this, iMovie would be my pick. I'd use the Music tool to make the music and the Video tool to make the final video presentation.

"Right tool for the job" ~~Hang B-)>

George, I am glad you got this question answered.

For my two cents' worth: I have been podcasting lectures (75 minutes) and smaller 2 minute exercises for my students last few months.

For lectures:
I record the lecture audio into my iPod.
Unlike you, I decided to bite the proverbial bullet and convert my Powerpoint slides to square 300 x 300 graphics. I did not shring them, though. I took the original powerpoint file, re-saved it as, e.g., "Lecture25_podcast.ppt" and then cannibalized it to the bone, so that each powerpoint slide I wanted to podcast would be pared down to one or two 300 x 300 JPEG files.
Then I edited the audio in Garage band (75 minutes down to 60 minutes).
Finally, I slid in the JPEGs to the artwork track, making chapters etc.

All this because I wanted my product to be iPod compatible, so going to iMovie was not my desire. I do use iMovie for other podcast episodes, and editing there is sweet, but the amjority of work is artwork for .m4a.

Bottom line, you are now richer by $0.02! 🙂

I've been struggling with this over the last few days.

I've found a reasonably cheap piece of software Profcast that enables recording of a continuous audio track over a Powerpoint presentation. This can then be saved direct as a podcast or into Garageband where it can be fully edited to create a work of art!

The problem I have is that I want to also use this on web pages and it is just too small - I want to create something that shows at 320x240 - any ideas??
