Pro Show Gold is very good software, you may find that it does what you are looking for
I can't believe I'm having such a hard time finding an answer to this question...
All I want to do is select about 100 different photos, add an audio track, and make the photos transition to the beat of the music. Ideally, I would like to be able to click my mouse, or hit the spacebar, or SOMETHING, in time to the music to indicate when I would like for the slides to change.
In VideoWave 7 I've seen how to determine the duration of each slide, but doing that individually is EXTREMELY tedious. I just need to play the song, and tap along with the beat to make the slides transition Each slide wouldn't necessarily be the same duration... i.e. there might be a section of the song where the slides would transition much faster or slower...
If VideoWave can't do this, is there a package that can? I'm desperate!
