I use SeaArt Ai with Flux model and Lora’s.
I have a paid membership, but there is free as well.
Link is below if interested. There is an app and website, but website has much more functionality when not on mobile platform.

I prefer to create images and get them clean.
Then make videos in SeaArt from the images.
The video clips use a lot of credits, so I experiment with the image creation which is unlimited for me.
I have start sharing some videos on TikTok.
