This is a remix of the Pollyanna song, of combining two versions of it into one. The first version is the vocal version, from the video whose ID is bmA5bGv6FSQ. The video in this video is based on that from that video, which displays the lyrics. The second version is the instrumental version from the video games Super Smash Brothers Melee and -Brawl, taken from the video whose ID is YbV2P6ENOXE. The instrumental (Super-Smash-Bros.) version was transformed in pitch and linearly transformed in time (speed-dilated and time-shifted) to match to the vocal version; the vocal one is un-transformed. Because of the length of the song, it was difficult to synchronize the clips and it took a lot of tweaking, and at one point I even did a linear regression on correlated time-points. Also, one edit was needed near the ending of the song to repeat a single "verse", since both original versions end with a slightly different amount of verse repetitions in the coda. Also, since the clips start at different points, I adjusted the gain of the first one to "fade down" as the second one fades in.

What's really disheartening is that, after making the song reasonably good and mixing-down the multitrack audio project to the output sound file, in the process of importing the sound file to the video project I accidentally overwrote one of the input files to the original multitrack project, and corrupted that project. So I have the output file used in this video, but my source multitrack project for the audio is gone, and I'd have to start over in order to change anything like relative gains, etc. (less info)
