I am on a MAC 10.6.4 running AE CS5. I have an audio track (.wav or .aif or mp3)...it is about 20 minutes long. I want to coordinate effects when certain words are read. I am at a loss whether I am having problems or just don't know what I am doing.
I have tried the following by bringing into the comp...the MP3 and later with the AIF file (only using one of these at a time). What advice do you have for me making events happen at certain times against the audio track? Do I have to do the WHOLE RAM PREVIEW (takes a long time)? How do I listen to the track and put in effects?
I don't even know how to search for this problem on the web...
Two basic methods may help you.
1) Simply scrub the vide/audio with the Command-Option-Drag in the main timeline. This way you won't need to RAM preview everything.
2) Expand the audio layer so that you can see the waveform, combined with markers that may help you was well.
hope this helps
