How to sync images and sound under windows ? ... for free .. |

I found this one in my mail box today

I have to do an oral presentation for my art course in a few weeks.
Basically, I have 8 minutes in which to make a presentation on any topic I
want. What I want to do is use a projector, hooked to a laptop, to project a
slideshow of images. Along with these images I want a piece of music I wrote
to play with them. I'd like to have both the images and the music file
playing in sync so that each image changes on the beat of the music. The
song is playing at 150 Bps so that comes to 1 image every 0.4 seconds. I can
use adobe imageready to create a slideshow which plays at that rate but I
cant find a way to link audio to it. I tried using windows movie maker
because it can play image and audio at the same time but the closest rate it
plays at is 1 image per 0.375 seconds so my music and my pictures are
completely out of sync. Would you have any suggestions on how I can make
this work?

And of course this has to be done with freely available tooling. Maybe when I tried hard enough I could come up with some vague/clumsy ideas about how to do this, but have never actually done it ...
Any experts here ?

Better alternatives to Windows Movie Maker with independent timelines for audio and video are:
Sony Vegas (short learning curve)
Flash (might be a bit tricky without any prior Flash knowledge)
Adobe Premiere and After Effects
Not sure if this helps,

Premiere is good at this, and has a 30-day trial?
Also might try Wax (just starting to use it myself), or VirtualDub, but I don't know how much control one has with these programs yet.

This is mac stuff. A consumer mac like the iMac or whatever comes with the latest iLife bundle. There you have iMove, iDvd, Garageband and more.

You can make an excellent persentation with these tools.
Not free, but almost.. is the Keynote, a part of the iWork bundle. It is the perfect companion to the Ilife suite.
http://www.apple.com/iwork/keynote/
Presentations made with Keynote will even take out the most cokeladen Powerpoint heads out there.
Basically what you need is to get access to a mac with all this stuff on it.
One issue to consider is that a perfect timeline sync is best done with Adobe Director or using video ( as in iMove ).
There should be some open source Director clones out there somewhere though.

Virtual dub, that's the word :-)
I messed a bit around and I can make a video that runs at 2.5 frames/sec (150 bpm).
I used JPGVideo to convert a folder filled with images to an avi running at 25 fps.
Then I imported that avi into virtual dub and converted the frame rate to 2.5 fps.
The resulting avi can't be played by the windows media player (it crashes on it here), but I could import it into windows movie maker. Next thing would be to import the sound file and then export the whole thing as a wmv file.
Probably the audio file will have to be trimmed a bit (like adding a bit of silence maybe to the beginning and removing some samples here and there or stretching them a tiny bit) as it's almost impossible it will have an exact beat rate of 150 / minute. This could be done using audacity
A bit of a kludge, but for free and on windows :-)
