We had a good question come by today from someone starting to shoot a tribute video for a client. The question asked was about which aspect ratio to shoot in 3:4, the older style or 16:9 the new popular aspect ration size for HD and YouTube. They were also going to be projecting this video on basically a vertical screen which was a little odd, I think is was 8ft wide by 12ft high.
Here was my answer
I find with the 16:9 format you have to consider a lot about the video real estate on the left or right of your subject and people height becomes a problem. With 4:3 you can have taller subjects and you can fill the screen a little easier, but the 16:9 everything is widescreen, you just can't go that big.
I would also think about if you are dropping photos into the video, what sizes are the images that you have 5x7, 3x4, that kind of thing. I am assuming with a tribute video you might have a lot of older images. Again the same issue comes into play, a lot of photos fit easier with the 4:3, than with 16:9. You often blow up the image to fill the screen and to get it to fit left to right you loose a lot of the top or bottom of the of image. They just don't fit if they are older photos. A lot of new cameras kind of shoot in the 16:9 format but older ones didn't. I would test with some photos and see if they fit but I would say 4:3. If you have to go 16:9 you could do photo montages side by side.
Side note: I have had good luck with photos set up, horizontal at 7" wide x 5" high, 300dpi, tiff, rgb, also png works very well with FinalCut.
So I am not giving you a firm answer on this but look at the source material, and look after the video is done and see where that leads you.
Here is one final thought, Have you seen footage coming out of iPhones, it is often vertical and looks kind of odd, but you could crop your video in FinalcCut to fit the 2:3 format size of their screen. It would take a bit of work in editing getting everything in that format and I would center the images on a black or white backgroun and then bleed that part off the edge of the screen when it is projected, but you could get it to fit in that format. It might limit its future use but it is doable. I would test first.
