I had a situation arise a few days ago when an interview guest gave me about 60 picture files to use for the interview just before the show recording was to begin. The easiest way to get all those images into vMix was to create an input List and select all the files within the provided file folder. However, when I brought that List input into my Preview window, I had no way to quickly & easily scroll through the images visually to select which one I wanted to show. So I had to delay the start of the show's recording so I could sit down with my guest and pick a few select images,... inputting them into vMix one at a time and limited to the amount of picture inputs thumbnails I could fit into the screen real estate of a particular colored bin, which was just over a dozen.

Is there a way to modify the LIST input preview window to add a next/previous capability to allow a user to visually scroll through media within that list? This capability would be very much like how a user can select a particular slide in a PowerPoint input window?

Bardos, although your solution is adequate for just one input list, it doesn't help if you have two or more input lists that you may want to toggle back and forth in preview before sending it LIVE to the program which may already have another list. I would have to create individual next/prev short cuts for each input list.

Also, this may be a bug report that I'll have to research, but it seems the all the images in my list want to play the next image immediately until the end of the list. I have deselected the "Automatically Play Next" option in the list settings, but it doesn't stop this action. So even when I tried the short cut key solution you provided, my "previous" image flashes for a moment then goes to the next/last image. I'm currently using version 14.0.0.112 x64.

Bardos, have you tried your solution with a list of JPG files? Doesn't work for me.

Ok, I think I get what you want to do.....put all the photos in a folder, select "Add Input", and select "Photos", and navigate to the folder where you have the photos....then click OK....Next, Right Click on the image that is displayed, and select "Slide Show Settings"....what I did, is to set Transition to "0", and the duration settings and effect, and when I came back to the Main GUI, I just have to click on the Play Button to toggle forward, but the same settings I mentioned in a previous post, works the same way.....the Right arrow toggles forward, the Left arrow toggles backward in the "Preview Window"
If you want to scroll the photos live, just click on the Forward/Reverse arrows at the bottom of the Output Window, and that's it....

No Problem my brother, that's why this forum was created....to help those who find it a bit difficult to do certain things in vMix, and to get the most out of this program....
