Hi,

I am doing a multi-media presentation for an audience in two weeks. I am trying to determine which format would be best.

The video needs to be smooth, of a high quality, and the audio needs to be synchronized with the Video.

I made the opening animation using Adobe After Effects, which gives me three main export options: AVI, Quick time, and Shock-wave Flash.

The problem is, with all of them, the audio and video tracks are not synchronized. So, you hear the thunder crash BEFORE you see the lighting, which makes no sense.

My other options are to output to DV via fire-wire, or burn to CD/ DVD.

The other issue is, it needs to be interactive. I have to be able to click next, and go back if necessary, in a fashion which is similar to power-point.

(Of course I can't use power-point, due the the AV limitations of the program.)

So it really comes down to flash...

Is there a way to pre-buffer video so that it "knows what it's doing" before it starts?

I exported the file to AVI, which is decent (but as I said earlier, the Audio and the video aren't in sync). In this format, it takes 1.65 GB

Which is three times the amount of physical RAM i have installed (512).

If anyone has any ideas about this let me know.

I don't care how large the file is, or how long it takes to load, as long as it's plays straight through, CONSISTENTLY, every time.

One more question, Can I make a CD-R with inter-active content play on a DVD player?

(I don't have a DVD burner, but I could access one if necessary.)

Thanks for any assistance,
Nick M. Rahl

To resynchronize avi, use Virtual Dub.
See link:

To avoid giga files use DivX (use 50 as keyframe interval for easy back and forward seeking)

You could have short avi movies in a player supporting playlists.
Like BS Player.
Make a separate video file for each sequence you want to repeat or jump, and add them to the playlist.
