I pasted no such info from Apple, from anywhere.
I created this list of what you can do with an iPad based on what I do everyday with my own iPads.
You can certainly do video editing and graphic design on an iPad.
Many video editing apps for iPad, including Apple's own iMovie and, just recently introduced, Apple’s Final Cut Pro.
Also, video editors, like LumaFusion, which has been with iOS/iPadOS for, at least, the past 5 years!
For Graphic Design, there are apps from Serif Labs called Affinity Publisher, Designer, Photo.
All available for a one-time price for each app OR a more expensive one time price if you want the Affinity grraphics design apps for both iPadOS/iOS/macOS, all for a one-time price.
OR
Adobe Systems Creative Cloud which consists of every app Adobe makes for both graphic design AND video editing, which includes InDesign, Illustrator, Photoshop and Premiere, for a monthly subscription price.
You are not going to fimd free apps to do these activities.
There are too many apps, in the Apple iOS/iPadOS App Stores to be able to list all of the apps avaiable for specific activities you wish to try/accomplish.
You really need to do your own homework/research to find out what app/s you think yoy would like to pay for/download to do the things you want to do with your iPad.
Many third party paid,,creative apps,,usuaully, have some sort of trial use time amount, to try an app out for a period of time, before making a purchase of that app.
These support communities are not a place to find lists of recomended apps for a specific use, nor is this a place for posting personal tutorials of apps.
You need to figure out what, exactly, you want to do with both video editing and graphics design ( personal, commercial/professional or online media use ) and anything else you think you might want to use your iPad for, before anyone here can begin to recommend any, potential, apps to look at, from the iOS/iPadOS App Store.
Many places online to find info on iPad apps for all sorts of specific activities.
YouTube is an excellent source for both finding apps for all types of tablet apps for specific tablet activities and is an excellent source for video tutorials, on specific apps, as well.
Best of Luck to You!
