A lot of work has been done on the audio and video recorder skins for the last few releases of Poodll. In particular the new Burnt Rose skin and the 123 Recorder skin. The latter was designed specifically to make it clear to the recorder that they needed to upload the recorded file, before saving/inserting on the current Moodle page.
The audio version looks like this in its ready state.
As each of the three phases: record, play and upload, are completed a green tick appears below the completed steps.
The video version looks very similar.
See here for information on how to choose the 123 recorder (or another recorder) for your site or activity.
N.B. In Moodle version 3.1.x and 3.2.x those nice icons on the recorder are not available by default. In that case you need to add a line to your “additional html” area. See this page for details on that: https://poodll.com/docs/font-awesome-moodle-and-poodll/
