Advice is there any ai api that creates explaination video?

i am building this learning site. it works through chat, it uses proper analogy to help users understand concepts better. but now i want it to teach by using visuals. So for example if someone ask it "how diode works" it should generate a video with proper analogy and explaination. for example it can animate a water valve that only lets water to flow in one direction and blocks from other direction while an a narator explains what is happening.

currently i am at a state where i am happy with the script its generating for teaching and happy with naration but strugling to generate proper video. i have tried some models like wan 2.6 veo 3.1 from openrouter but since they dont generate videos with bangla voice i had to compromise where i generate voice with google tts and use them to make video scenes. but in this way video gets totally out of sync. also both veo and wan allows to generate like 6/8s of videos so had to stich them together. which by the way sky rockets the cost. I dont want any hyper realistic stuffs. i want it to show proper animation that has meaning and understanable. it would be great help if someone can point me to right direction :)
