Don't worry about that, I am gonna use the one I've already got almost done, I just need to finish a few things. I had to change the original idea a bit to make a better sync with the events, but it's not like I had to erase half my movie, all I had to do is allow some movie clips to run for a bit more of time, and change the idea a bit for making the movie have more connection with the song, but nothing too big.
I also put my whole movie inside one movie clip, to make things easier for you, that way, all you have to do is paste the MC in the root timeline and allow it to run for whatever frames it has (I'll specify that in my movie, don't worry). This also helps to prevent the files from cracking up, if for some reason you have problems putting it all together, you won't have to start all over again.
Also, yesterday I found out my mother suddenly likes Linkin Park, so I've got another reason for finishing my part!
And... a little update!
It isn't too changed because I was in vacation, but now I'm back on wheels :)
