[Heather Crank] ” called said store’s corporate headquarters to try to get a screen size. I was told it varies, most screens are not hd… So I think 4:3 would be a safe bet. But how to make this animation flexible, incase the size of the screens vary? “
I wouldn’t assume that 4:3 is a safe bet until the client specifically tells you that. If some of the stores do have HD or 16:9 panels, your content will either be pillarboxed or stretched.
I’ve had to repurpose existing 16:9 content for 4:3 screens before, and I did it by hand. I started with 16:9, then added in pillarboxes to show the 4:3 area. It was a lot of precomping, rescaling, repositioning, and re-keyframing. It’s tedious work, but since the aspect ratio has a huge impact on layout, there’s no automatic way, so it was worth the effort.
Planning ahead, you can start in 16:9 with a 4:3 guide layer while you work, and either center-cut or pan-and-scan your 16:9 work to 4:3 later.
Alternately,you can work within a 16:9 safety frame over a larger 4:3 background — for example, working in a 1920×1080 portion of a 1920×1440 comp. Look to the 16:9 area for your action/title safe, but think of the 4:3 like printers think of bleed.
These workflows assume one ratio will be important, and one is secondary.
If they are both important, you should do two separate versions, so plan the relationship between design elements carefully. I would only create the second version after the first one has final approval to avoid repeating work unnecessarily.
