[SOLVED] MoviePy Error: failed to read the first frame of video file

I'm having a similar issue to this thread, but the difference is that I'm not attempting to change folders at all, it still should be able to read the file. I don’t see why there’s an issue with it?

for x in newfiles:
    x = x + ".mp4"
    xstr = x
    xstr2 = xstr.replace(".mp4", "")
    x = VideoFileClip(x)
    x = x.resize(width=720)
    durationsecs = x.duration
    fullclip = CompositeVideoClip([bgnosnd.set_position((0,0)).set_end(durationsecs), x.set_position((0,20))], size=(720, 1080))
    textclip = TextClip(f"Part {xstr2}", font="fjalla-one.ttf",fontsize=125, color="white", stroke_color="black", stroke_width=5)
    textclip = textclip.set_pos('center').set_duration(durationsecs) 
    fullclip = CompositeVideoClip([fullclip, textclip])
    fullclip = fullclip.volumex(per)
    fullclip = vfx.make_loopable(fullclip, 0.5)
    fullclip.write_videofile(f"final{xstr}")

The code processes both input videos properly, and does spit out a working output file before throwing the error, but I'm still unsure how to fix the error. It seemed to work before on a testing file, but I have made a couple changes since then. One thing to note is that my current file was converted from an mkv file to an mp4 file with this code:

  convert = VideoFileClip(filename)
  convert.write_videofile(f"converted_{filename2}.mp4", codec="libx264",audio_codec="aac")

I've tried to do this with multiple files that are converted with the same code, but none seem to work. Another thing to note is that my python and pip only work with "pip3" and "python3", and not normally - I was unable to install imagemagick through pip3, but i got it to work with brew Full error:

On Ubuntu/Debian for instance the version in the repos is deprecated. Please update to a recent version from the website.
