Another question from me. How do I make two videos flashes to the beat. For instance, scrub through 2:34 - 2:36 of this video
I know this takes painstaking job to do but pls don't tell me to zoom in split every clips to make them flash to the beat. that's crazy!! xD I need a systematic way of doing it. I believe there is! Thank you guys. ;)
I've been editing 15 years, if you want flash frames like that, most of the time you pretty much do it as you described. You lay the outgoing track over the incoming for 20 frames or so(depends on the music) and yes, you cut every other frame of the track out.
If you are going to do this in AE you could use a simple expression. Set up your layers with the outgoing layer on top, extending the length of the transition. Set an opacity keyframe for 100%, go to the next beat of music and set a keyframe at 0%. Select both keyframes make them hold keyframes(Cntl+Alt+H). Now Alt+click your opacity stopwatch to create an expression and use the loopout expression:
The nice thing about this, is if you get a different beat structure you just need to adjust 2nd keyframe and the loopout will automatically update. Here's a simple project demonstrating the technique: 5400_flashframe.aep.zip
