Quite a bit can be improved if I'm honest. I once generated a video with a "Studio Ghibli" template setting which the site itself provides as a pre-set and was horrified to discover that, entirely unprompted, the model had inserted the licensed character "Totoro" into many of the videos it had generated, rendering them nonsense and entirely useless. To Revid's credit when I complained about this they refunded me 400 credits, which went some way to compensation but to be honest the video had cost twice that. Some companies would have ignored me completely, so I guess partial credit where its due. There are lots of other technical issues too - each individual video generated has an initial image prompt and an animation prompt, but these are kept on separate tabs of the UI and when you click away from one tab, any changes you've made are lost instantly which is a CONSTANT pain.
I suspect if I were a more savvy user I'd have a list of complaints as long as my arm, but a novice like me is able to knock some half-decent music videos together without too much of a technical headache, so for my needs it's fine. I do think the "Pro" and "Ultra" AI model tiers are CRAZY expensive, however.
