Anyone else getting giant, stroby/corrupt videos after combining 3 images using ImageClips in moviepy 2.1.2?

~~ Quick Note before starting: I've been debating if I should post this since it's similar to #2368, but my implementation of ImageClips is different (they used ImageSequeneClips, while I manually combined ImageClips and Colorclips) and I was able to produce a working-ish video of the problem as well as a download link so you can examine it yourself ~~

I've been trying to use Moviepy to make a QR-code photo slideshow. In theory, it should be as simple as doing something like this:

class Videoification():
	def __init__(self, file_path, output_path, verbose=False, initial_data_buffer=5, frame_buffer=5):
		if not Path(file_path).exists():
			raise FileNotFoundError(f"File '{file_path}' does not exist")
		self.file_path = Path(file_path)
		self.output_path = Path(output_path)
		self._processing_folder = Path("C://Users/jediw/Documents/GitHub/Infinite-Cloud-Storage-Solution/downloaded_files/" + self.output_path.name)
		self._processing_folder.mkdir(exist_ok=True)
		self.frame_buffer = frame_buffer
		self.initial_data_buffer = initial_data_buffer

	def compile_video(self, qr_codes=None):
		from moviepy.config import check
		check()
		clips = []
		qr_codes = qr_codes or [Path(str(qr_code)) for qr_code in Path(str(self._processing_folder) + "/QR Codes").iterdir()]
		for qr_code in qr_codes:
			if not qr_code.exists():
				print(f"[WARNING] Queried QR Code PNG '{qr_code}' does not exist")
			qr_clip = None
			try:
				qr_clip = ImageClip(str(qr_code), duration=self.frame_buffer)
				clips.append(qr_clip)
				print(f"Processed QR Code '{qr_code}' (size: {qr_clip.size}, duration: {qr_clip.duration}, {qr_clip.save_frame(str(self._processing_folder) + f'/QR Codes/FINISHED{qr_code.stem}.png', t=1)})")
			except Exception as e:
				print(f"[WARNING] Error occurred while processing QR Code '{qr_code}': {e}")
			# if isinstance(qr_code, Path):
			# 	qr_code.unlink()
		if not clips:
			raise FileNotFoundError("No QR Codes were found to compile into a video")
		video = concatenate_videoclips(clips)
		initial_buffer = ColorClip(size=video.size, color=(0, 0, 0), duration=self.initial_data_buffer)
		video = concatenate_videoclips([initial_buffer, video])
		video.write_videofile(self.output_path, codec='libx264', fps=24)
		return video

if __name__ == "__main__":
	video = Videoification("README.md", "read_me_videoification.mp4", frame_buffer=100)
	video.compile_video()

However, life can't be that simple. When I tried to combine these 2 QR codes:

I would only get a pitch-black video. Then, after hours of troubleshooting, I eventually decided to try adding some random screenshot I had saved on my computer to the mix (sorry in advance):

Apparently, moviepy HATED this screenshot, as its resulting 1-and-a-half-hour video was so scuffed that it crashed my code editor upon loading it. Windows' built-in media player also refuses to play video. After downloading a new media player in an attempt to play the resulting video, it looked like this:

Screen.Recording.2025-02-10.002847.mp4

If you want to look at the video's internals yourself, I'll link it to this Google Drive. As for system specs, I run an A MD Ryzen 7 5800H with 16GB of RAM and an RTX3050Ti as the graphics card. Software-wise, I'm on Windows 11 24H2 (Build 26100.3037) using Moviepy v2.1.2. Any ideas for what's causing it?

You should try pass method="compose" to concatenate_videoclips
