Change Default Duration - HD Image/Video Player


I’ve got a change “HD Image/Video Player” with 1k pictures and I’d like to change the duration of each picture to 20s (instead of 5s). Is there a way to accomblish that or do I need to change the duration a thousand times?


Partially answered here: Add asset folder or multiple assets to a change "HD Image/Video Player" setup.

Alternatively, although not recommended, as the proposed solution is easier, it is also possible to fork the hd player package, change the default value and import the modified version into info-beamer.
