We're currently working with Filepicker.io to allow users the ability to upload both images and videos. It appears that if we specify image conversions in the Javascript API options, video uploads don't process and instead get stuck at 99.30%. If I remove the 'conversions' option, video uploads process without issue. Is it not possible to specify image conversion options and accept both type of uploads? If so, this should really be specified in the docs.
I attached a JSFiddle with the code in question. http://jsfiddle.net/BYkD4/
