Affinity photo and affinity design are quite good replacements for Photoshop and illustrator respectively. You can get them with a one time payment. I got them during a promotion and i was able to get both for 30 USD. I have been using them for about 6 months now and i find them quite good, even though, having used Adobe tools for a long time, i miss the familiarity with the interface and the shortcuts and some of the more advanced features. I am not that he expert with video editing to be able to recommend alternatives unfortunately...
