Hi

here's some solutions

- instead of overlaying your 4:3 slides over your 16:9 camera input, just switch to it using a transition effect. vMix will sort of add black borders

- create a black input and use the multiview feature to add your beamer's presentation capture as overlay #1
now when you use this input (as an overlay like you seem to be doing), you have black borders

- if you want to improve your production, you can also use a nice background image maybe with your church logo/design and use it to create a multiview where you can associate side to side your camera feed (smaller) and your presentation slides (larger). This way your video is always in the 16:9 aspect ratio

Hope this helps

Thanks for replying, much appreciated!

The reason for me to put it in the New Feature part of the forums is because I think this would not only fix my issue, but also improve the software. There aren't so much triggers, so to add a couple wouldn't hurt I guess. (OnOverlay1ZoomIn, OnOverlay1ZoomOut etc.)

@DWAM Thanks for the suggestions. But the beauty of the zoom effect is something I like to use in the productions. I could obviously transition to the full screen, but using the zoom option is a bit more appealing and looks more professional.

@Icestream I tried it today but the image gets too distorted indeed.
