Inpainting with external model ?

[simartem]

Thank you very much for the implementation of the beautiful project into Comfyui.. Its greatly appreciated.
The point for me is, in video completion, i was trying to remove a watermark for testing purposes.
The inpaint model is not succesful completing face like human instances. It is succesful inpainting objects.
Whereas the hat of the model was inpainted in a very nice way, but the face became into an alien :-) and for long seconds.. not in a few frames. So my question here is,

1. is it impossible to use an external model like Flux.Dev (including the seed) or etc.. for the mask combined areas with the video ?
2. if first question has a positive return, is it possible to create a "clip text prompt" input in specific ranges of the video ?
   For example : "0-10 frames" --> Face of a man, "11-37 frames" --> red sports car, "37-162" --> carpet on the floor..

Otherwise if i'm not wrong, the inpainting purpose of the project will remain removing something from the scenes where no living creatures are placed like a man, woman, cat, dog.... Because they are distorted in shape when inpainted.
