When adding a clip, if it's a video or audio file, we'll make that file playable in the report. You can then add additional supporting images to the clip, like a still image of your choice from the video or a station logo etc.
To add extra images to a clip, click on the add/edit images button above the clip image and click on the + buttons to add them.
