输入视频片段不存在: {first_clip_path}

Error message

What it means

generate_video raises FileNotFoundError when first_clip_path (the input video segment for video-to-video continuation) points to a non-existent file. Fail-fast validation before any API request.

Solutions

1. Check os.path.exists(first_clip_path) before calling and correct the path
2. Ensure the previous step that produced the clip wrote to the expected save_path
3. Use absolute paths in pipeline configuration
4. In Docker/K8s, mount the directory holding the clip

Example fix

// before
client.generate_video(prompt, first_clip_path='tmp/clip.mp4')  # FileNotFoundError
// after
clip = os.path.abspath('tmp/clip.mp4')
assert os.path.exists(clip), f"clip missing: {clip}"
client.generate_video(prompt, first_clip_path=clip)

import os
if first_clip_path and not os.path.isfile(first_clip_path):
    raise FileNotFoundError(f'输入视频片段不存在: {first_clip_path}')

def is_existing_file(path) -> bool:
    return isinstance(path, str) and os.path.isfile(path)

try:
    video = client.generate_video(prompt, first_clip_path=clip)
except FileNotFoundError as e:
    logging.error(f'Input clip missing: {e}')
    video = None  # regenerate or locate the clip first

When it happens

Trigger: generate_video(..., first_clip_path='clip.mp4', ...) where the clip file is missing — e.g. the video was generated in a previous run into another directory, or the extension/name differs.

Common situations: Pipeline where the clip comes from a prior generation step that output to a different save_path; file overwritten/removed by cleanup jobs; wrong cwd for relative paths; not copying the clip into the container.

Understand the failure class

Background: "File not found" and ENOENT errors: why libraries can't find a file that should exist — this error's family across 50 libraries.
