hmmm I dont know how you made this but Ill telll you my method with a gopro.
1. shot timelapse
2. import to your comp
4. import all photos into picasa in one album
5. use the vid or slide show option I forget what it is called.
6. select the time lapse transition and play with the speed
7. export and bam crisp
this is the time lapse vid I took with my standard Gopro which I have upgraded since then and it looks decent
