Poodll has two plugins for the Moodle Assignment, the Online Poodll Submissions plugin and the Poodll Feedback plugin. The adminstrator settings for each plugin are available under:

Site administration -> Plugins -> Activity Module -> Assignment

 Both allow the administrator to set the type of recorder's available, and whether to display the current submission or feedback on the form.

The Online Poodll Submission plugin also allows the administrator to specify what size to display, or to hide, the user submissions.

Some responsive video players (Flowplayer First Frame is one) may not respect the size settings. In this case set either "Do not display video" or choose a different video player, eg VideoJS
