A New File - 2_6) BG_Changer v2 has been added in the GDrive folder :

https://drive.google.com/drive/folders/1HoZxKUX7WAg7ObqP00R4oIv48sXCEryQ

.
Now you can have consistent custom Single Background or Sequence background.

Better backgrounds which are close to inputted image.

Prerequisites

1) If you are new to this workflow, Watch these Video and tutorial first to get how things work:

2) Controlnet - SoftedgePlus and AutoMask from this workflow: https://www.patreon.com/posts/update-v3-0-lcm-96482739

Breakdown 1 [ Single Background ]

Render Video Link : https://youtube.com/shorts/Xayw0JYn6yI

Controlnets weights -
1) SoftedgePlus [ 0.9 , 0 , 0.85 ]
2) OpenPose [ 0.8, 0 , 0.8 ]

.
Softedge and Auto Mask generated from file 1_1) Controlnet_Automasking_SoftedgePlus : https://www.patreon.com/posts/update-v3-0-lcm-96482739

Since It is not LCM Settings are updated to the following in the workflow file.

Backgrounds:

.

1) Umute the Single Group and Connect it the Image Adjustment node to use it (See the Above Picture For Reference

2) Upload a single image into the Background Single Node

One By one, the above backgrounds were uploaded to the background node and rendered.

CON

Flickering is observed in the renders of Single Background.... will try to fix this.

It's due to injection of Background latents in the middle of the render process, so it acts like img2img renders and flickers.
It can be reduced by decreasing the value in "Start Highres Fix from nth Step" node ) but the original background will be lost.

------------------------------------------------------------------------------------------------------------

Breakdown 2 - [ Sequence Background ]

Render Video : https://youtube.com/shorts/wzfYILSeTMA

All Controlnets Settings, Mask , and other were same like the Single Background one.

Background

The Fire Video was brought into after Effects, cropped and Rendered out as Image Sequence, and then the folder path was used as the Input in the background node.

Like this:

Unmute Background Sequence Group and Make the connection to Image Adjustment node

For Part 1 normal "Yellow" was used for Fire and In Part 2 - It was color hue shifted to blue with the above adjustment to look like a Blue fire which will after render will looks like "Abstract water fire"

Multiple Loras and It's weights were tested and the 4th one has the most "water fire" with similar fire physics and motion, So went with it.

Face Fix Reactor

1) Images were refined

2) Then face fixed with v2.1 Face Fix file then

3) Face swapped with scarlett johansson using the old "5) Batch Face Swap - ReActor [Experimental] workflow" with the following settings:

Then All frames were composed in After Effects
