I just add some functions to my fork. I want to merge it to your code.

The temporary output can help avoid confusion due to incomplete downloads. However, removing os.path.exists might lead to redundant downloads, even if the file already exists in the target directory.

"os.path.exists" is repeated.
Here is the code from anime_dl.py

try:
    ffmpeg.input(fp).output('x.png', vframes=0, loglevel="quiet").run() #check if the video is exist and not damaged
except ffmpeg._run.Error:
    try:
        os.remove(fp)
    except:
        pass
    try:
        os.remove(fpt)
    except:
        pass
    video_url_validator.validate(episode)
    downloader.download(episode)
else:
    print("Skip "+fn+" (downloaded)") #the downloads will be skip if it's exist and not damaged. so it won't cause redundant downloads
