Question about 4K editing ability on certain phones

So, I've been using Kinemaster on my Poco X3 Pro and it has been behaving decently well. But I'm worried that if I ever upgrade I would buy a phone that somehow performs worse in editing/4K exporting, despite its specs being better on paper. Is there any way I could figure it Kinemaster performance out beforehand? Is there any site or resource that keeps track of which phones can do what in Kinemaster?

If not, do you guys believe that the Nothing Phone 2a powered by the Dimensity 7200 Pro would be able to export 4K video and handle lengthy projects without glitching? If not, could the Redmi Note 13 Pro 5G or maybe the Samsung A54 do it?
