====== Unique media per subject ======

REDCap allowed for the embedding of media into a data collection form.  This is often a audio of video clip.  This is done by specifying the url of the media that should be embedded.  It is possible to use the **piping** feature of REDCap to make these links custom for each subject or event.  To do this, create a new variable to hold the location of the subject specific media.  For this example, **url** was used.  This variable can be marked with the **action tag** @HIDDEN or @HIDDEN-SURVEY so the participant does not see the link.  Next, set the **Embed media** value to be the piped version of this variable, which in this case is **[url]**.

After this configuration, the user specific values of the piped variable can be either entered through the standard data entry screens or imported using [[userdocs:redcap_usage:base:data_import]].
