wanted this for a while, will have to check this out. do you have servers mashing the video clips and keeping a video link on youtube or just keep appending?
The clips are stored individually on our end and played in sequence in the app (this allows for easy scrubbing/segmenting of series of clips, as well as things like watching friends' updates as they post videos). The YouTube compilation is all the clips exported from the app and then I put some music in the background.
