I'm working on a small video project using Python and MoviePy, and I want to create a color clip with rounded corners to use as a background. However, I'm unsure how to achieve this effect. So far I have a rectangle background !!. Can anyone give me a small example on how to add rounded corners to a color clip in MoviePy?

我正在做一个小视频项目,使用的是Python和MoviePy,我想创建一个圆角的彩色剪辑作为背景。然而,我不确定如何才能达到这种效果。到目前为止,我有一个矩形背景!!.有没有人能给我举个小例子,教我如何在MoviePy的彩色剪辑中添加圆角?


from moviepy.editor import VideoFileClip, TextClip, CompositeVideoClip, ColorClip
# Create a color clip as the background
color_clip = ColorClip(size=(video_clip.size[0], video_clip.size[1]),
color=(0, 0, 0), duration=video_clip.duration)

# Set the opacity of the color clip
color_clip = color_clip.set_opacity(0.4)

# Set the position of the color clip and text clip
color_clip = color_clip.set_position('center')

I am imagining a cute bubble in a nice enviroment, so I define a bubble. :)

我想象着一个可爱的泡泡在一个美好的环境中,所以我定义了一个泡泡。:)


from moviepy.editor import *

bubble_size = 30 # diameter of the bubble

1. Create a square ColorClip for the bubble


bubble = ColorClip(size=(bubble_size, bubble_size), color=(255, 255, 255))

2. Create a mask that is black everywhere except for a white circle in the center


def make_circle_mask(size):
Y, X = np.ogrid[:size, :size]
center = size / 2
distance_from_center = np.sqrt((X - center)**2 + (Y - center)**2)
mask = 255 * (distance_from_center <= size / 2)
return mask.astype(np.uint8)

circle_mask = ImageClip(make_circle_mask(bubble_size), ismask=True)

Circle_MASK=ImageClip(Make_Circle_MASK(Buid_Size),isMASK=True)


3. Apply the mask to the ColorClip to get a round bubble


bubble = bubble.set_mask(circle_mask)

Now you can position and overlay the bubble on your video as needed


Alternative Easier Solution:
If you have an image of a bubble (or any other shape) that you'd like to use, you can simply load it with ImageClip and overlay it on your video. This might be easier if you want a more complex or stylized bubble shape. However, if you're looking for a simple round white bubble, the method above should work just fine.

另一种更简单的解决方案:如果你有一个气泡(或任何其他形状)的图像,你可以简单地用ImageClip加载它,并将其叠加到你的视频上。如果您想要一个更复杂或更具风格化的气泡形状,这可能会更容易。然而,如果您正在寻找一个简单的圆形白色气泡,上面的方法应该可以很好地工作。
