How to apply art style to video?

I’ve tried some of the image style variations and settled on a particular one that suits my project (“Ancient Mural”). The problem is that I can find no way to consistently apply that style to an existing video. I’ve tried a couple different methods:

  1. Creating an image of the first frame of the video using the applied style and then referencing that with the original video as source
  2. Copying the “style:AncientMural” prompt tag and pasting in the video prompt and telling it to use that style throughout the video

Both methods work but with a glaring issue – the new style is only applied until the scene changes, and then the style reverts back to the original video style.

Do I have to:

  1. Capture the first frame of each scene change in my video
  2. Convert the image style for each start frame
  3. Cut my video up into separate scenes so I can use the image(s) as reference(s) for each video snippet?

Seems like a lot of extra work – I thought the “I” in “AI” was for Intelligence?

UPDATE:
So I created a short video - 3 “scenes” in about 5 seconds.
I cut the video into 3 separate clips based on scene change
I then created an image file from the first frame of each “scene” clip
I used the “style:AncientMural” prompt on each of the 3 images

RESULT: Each image was rendered in a slightly different way. The AncientMural style includes a border and some stylistic curves applied to the artwork. In each image (scene) the border was different, and the curve style was different, so there was no use rendering them to video, as there would have been glaring differences in the style as each scene changed in the completed video.

Can someone from RL (perhaps Howard Huang) explain how to employ consistent style across changing video (in this case, the video had been previously generated by prompt, so I couldn’t reference any 3D scene to apply the style)? Thanks
