This is the development repository for DLTdv and friends. See http://www.unc.edu/~thedrick/software1.html for stable versions, sample data and so on. Current development by Ty Hedrick is focused on DLTdv6, which works on the latest versions of MATLAB, introduces a "sparse" data file format which only stores the not-NaN data and has an option for only updating the active movie, greatly reducing display latency for projects with several compressed video files. DLTdv6 currently DOES NOT have a multi-track option, so if you're using that stick with DLTdv5 for now. Ty Hedrick, 2016-06-14
