Automatic concatenation and annotation of videos

Nobody has claimed this yet.

Studies often generate many short clips, and it's much easier for coding to have these put together into one video per session (with embedded labels). My own coding workflow does involve doing this automatically (see https://github.com/kimberscott/lookit-data-processing); it would be helpful to be able to provide concatenated clips directly to researchers, but this will be a substantial task as the video processing will have to happen on one of the servers, triggered by finishing the study, and this is fairly computationally intensive. Also, we may want to set up to allow frames to create video labels as a special type of recording an event, and then put those labels on the videos at those times as we do for Molly's videos.

Start by reviewing the linked lookit-data-processing workflow and the issue's proposed server-side processing and event-based labels. Clarify when processing should be triggered, how labels are represented, and what researchers should receive; done would mean one annotated video per session is produced after study completion.
