This is ComfyUI for
advertising: B-roll creation.

00:04.909 --> 00:07.729
This workflow generates or
modifies B-roll footage.

00:07.989 --> 00:10.179
It has three methods for
different production needs.

00:10.639 --> 00:13.079
Experiment with all of them
and choose the one that fits

00:13.089 --> 00:14.589
while bypassing the other two.

00:15.049 --> 00:16.609
Method one is prompt only.

00:16.989 --> 00:20.159
Write a description of the shot
you want in the text node and

00:20.159 --> 00:21.859
Seedance generates it from scratch

00:28.845 --> 00:30.695
Method two is reference images.

00:31.045 --> 00:33.755
Load a still frame from an
existing production as the scene

00:33.755 --> 00:37.065
reference and a subject image for
what you want to insert into it.

00:37.565 --> 00:40.575
Seedance matches the lighting,
environment, and color grade of the

00:40.575 --> 00:44.405
scene reference and generates a new
clip with the subject placed inside it.

00:44.865 --> 00:48.435
Use this when you need a new shot
that has to match existing footage.

00:49.035 --> 00:50.655
Method three is video editing.

00:51.135 --> 00:55.205
Load an existing video clip, trim it
with the video slice node to isolate

00:55.205 --> 00:58.815
the section you want to work on, and
describe the change you want to make in

00:58.815 --> 01:03.645
the prompt: adding an element, altering
an object, adding a visual effect.

01:04.685 --> 01:07.925
Seedance applies the edit while keeping
everything else in the shot intact
