FileNotFoundError: [WinError 2] The system cannot find the file specified

Images are generated in the folder specified but FFmpeg throws this error when creating the video.

from stable_diffusion_videos.stable_diffusion_walk import walk

walk(
    prompts=['a cat', 'a dog'],

Do you know the root cause of this issue? Is it the ffmpeg command itself? Like do we have to point to something other than ffmpeg when calling subprocess?

[meet1919]

Yes, you are correct. From subprocess.py file I made some temporary changes and everything worked for me.

def __init__(self, args, bufsize=-1, executable=None,
                 stdin=None, stdout=None, stderr=None,
                 preexec_fn=None, close_fds=True,
                 shell="True", cwd=None, env=None, universal_newlines=None,
                 startupinfo=None, creationflags=0,
                 restore_signals=True, start_new_session=False,
                 pass_fds=(), *, user=None, group=None, extra_groups=None,
                 encoding=None, errors=None, text=None, umask=-1):

changed : shell = True from false

[nateraw]

Interesting. That should work on Unix as well right? If so, simple fix here.

[meet1919]

@nateraw yes I think so. you should add a parameter in the walk() function for specifying shell value, to prevent from making changes in the subprocess.py file.

Are there any animation settings for walk() like deforum_stable_diffusion ?

[nateraw]

Nope. The idea here was to use raw outputs of the model, not applying any animation settings.

If you'd like to discuss that, feel free to open a separate issue and we can. Would prefer to keep these issues focused on one topic at a time.

I am leaning towards not doing animation stuff, but I am happy to discuss and see if its something that we really want.
