speeding up videos

[osaexpressions]

So I read a thread about shrinking a video from an hour and a half down to 1 minute. Grazie's response was really helpful, i held control and was able to speed my video up 4 times, then rendered it. But I am unable to speed it up again. any advice? do i need to save it in a particular format? or do i need to make it into a movie then start a whole new project with it to do it again?
any feedback would be great!

You need to use the rendered file. i the file you crated when you rendered.
Import that into your project and shrink that.
Then repeat ad nauseam.
