I am creating a welcome png for a Jumbotron at a hockey stadium. When creating this, is it best to set your canvas size to the dimensions of the screen it will be showcased on? Or is it possible to create in on a smaller canvas and when exporting - save it as a larger image size. I'm also concerned it will become pixelated as the imported logos are pngs. If it's going to be blown up, is it better to use the vector files?
I believe the width will be around 20 ft and my computer can't handle this file size / not enough scratch disc space.
How fun! I'm a hockey fan. The Jumbotron manufacturer has specs. There are several manufacturers and new/old technology and software that you'll have to consider to know the resolution and color specs of their output. It also depends on the content of your welcome message. If just text, vector is going to be best. If there are graphics/images/animation/video then there are plenty of other things to take into consideration. You should get the exact sign and software info and get specs that look something like this: Size to 4920 pixels by 1800 pixels. Displays should be less than 200 dpi and less than 100 mb.
Then, I would create your canvas size to that exact spec. It's never great to start small and uprez. Hope that helps and more people will chime in here as well.
Scratch that, sorry, I read too fast. Yes you want your logos and text to be vector. Depending on the image I don't know how small you can go with it before it breaks up on the screen. You will need the specs to be sure so you don't overload your system or create a file size that is too big.
