Why is my quicktime file enormous? The stand alone version is only 110Mb but the same 4 minute slideshow with music is more than 10 Gb!
@kiwiph The size of a video file depends on the length, format, resolution and frame rate of the video. 4 minutes of uncompressed Full HD video can easily be 10 GB.
The stand alone version of the slideshow only contains the still pictures and a description of how to animate them. The render engine will create all the 10 GB (or more) needed to display the slideshow on the screen on the fly and throw the data away when it is no longer needed, keeping the memory requirements low.
