I created a shader filter and used it with a video as an input channel, it is working properly but I want to save the rendered frames and make a video out of it. Code: ```python import arcade from arcade.experimental.shadertoy import Shadertoy import cv2 SCREEN_WIDTH = 400 SCREEN_HEIGHT = 300 SCREEN_TITLE = "ShaderToy Video" class ShadertoyVideo(arcade.Window): def __init__(self, width, height, title): super().__init__(width, height, title, resizable=True) self.shadertoy = Shadertoy( self.get_framebuffer_size(), """ void mainImage( out vec4 fragColor, in vec2 fragCoord ) { // Normalized pixel coordinates (from 0 to 1) vec2 suv = fragCoord/iResolution.xy; fragColor = vec4(1.5 * sin(suv.y * iResolution.y/3. + iTime * 20.)); fragColor = 1.- floor(abs(fragColor)); fragColor *= vec4(sin(suv.y), 0, cos( 1. - suv.y * 2.) , 1); fragColor *= texture(iChannel0, suv); } """, ) # INSERT YOUR OWN VIDEO HERE self.video = cv2.VideoCapture("Example.mp4") width, height = ( int(self.video.get(cv2.CAP_PROP_FRAME_WIDTH)), int(self.video.get(cv2.CAP_PROP_FRAME_HEIGHT)), ) self.video_texture = self.ctx.texture((width, height), components=3) self.video_texture.wrap_x = self.ctx.CLAMP_TO_EDGE self.video_texture.wrap_y = self.ctx.CLAMP_TO_EDGE self.video_texture.swizzle = "BGR1" self.shadertoy.channel_0 = self.video_texture self.set_size(width, height) def on_draw(self): self.clear() self.shadertoy.render() def on_update(self, delta_time: float): self.shadertoy.time += delta_time self.next_frame() def on_resize(self, width: float, height: float): super().on_resize(width, height) self.shadertoy.resize(self.get_framebuffer_size()) def next_frame(self): exists, frame = self.video.read() frame = cv2.flip(frame, 0) if exists: self.video_texture.write(frame) if __name__ == "__main__": ShadertoyVideo(SCREEN_WIDTH, SCREEN_HEIGHT, SCREEN_TITLE) arcade.run() ``` Is there any way to save the new rendered frames and make a video? Please help :)
