-//TODO mj: one option for doing thumbnail previews of video in timeline?
-/**
- * 1. set vref in videobox
- * 2. when vref is set immediately process video to extract ~50 thumbnails
- * (^^ would make more sense to do this when video is initially uploaded)
- * 3. upload each file to server using convertDataURI and save list of URLs as field on doc
- * 4. in CST onHover, set hover time
- * 5. use hover time to figure out index of nearest thumbnail
- * 6. get URL of image and use source to paint canvas accordingly
