ok, it seems that there is no simple way to do the looping list with video and image files. I would put this issue into the whish list. Vmix can do so many other things that this should not be problem for Martin. There is no time in events to render separate video files from images in external editor, in order to use only video list in vmix. Basic situation: you have some logos and videos to loop in live events screens or stream while waiting the event to start.

Length for every image in seconds should be set individually
