还是之前文章介绍过地几个工具之一

[AI相关]各平台AI使用对比，包含大模型学习，生成视频等-CSDN博客

问问AI其结构，框架等，虽然不太完全对，但真地DeepSeek已经回答得很好了：

重点关注就两个类

video_engine和（实际上是video.py)
ai_generation(ai.py)

下面这个图，AI-DeepSeek直接给出得的是目录名，这就肯定不可能对的了，软件是不停迭代的，肯定会改名，也会在半年，一年内大幅度更新，目录名肯定不会“正确的”；但是整体框架（AI对框架的理解是非常好的，对我问的问题的立即也是非常好，这就。。。。。。。。非常恐怖了）

video.py

task.py 合成视频

# task.py
def generate_final_videos(task_id, params, downloaded_videos, audio_file, subtitle_path
):final_video_paths = []combined_video_paths = []video_concat_mode = (params.video_concat_mode if params.video_count == 1 else VideoConcatMode.random)_progress = 50for i in range(params.video_count):index = i + 1combined_video_path = path.join(utils.task_dir(task_id), f"combined-{index}.mp4")logger.info(f"\n\n## combining video: {index} => {combined_video_path}")video.combine_videos(combined_video_path=combined_video_path,video_paths=downloaded_videos,audio_file=audio_file,video_aspect=params.video_aspect,video_concat_mode=video_concat_mode,max_clip_duration=params.video_clip_duration,threads=params.n_threads,)

最终还是回到 video.py

video.py 生成视频

def preprocess_video(materials: List[MaterialInfo], clip_duration=4):for material in materials:if not material.url:continueext = utils.parse_extension(material.url)try:clip = VideoFileClip(material.url)except Exception:clip = ImageClip(material.url)width = clip.size[0]height = clip.size[1]if width < 480 or height < 480:logger.warning(f"video is too small, width: {width}, height: {height}")continue

python fileClip库

material.py

def download_videos(task_id: str,search_terms: List[str],source: str = "pexels",video_aspect: VideoAspect = VideoAspect.portrait,video_contact_mode: VideoConcatMode = VideoConcatMode.random,audio_duration: float = 0.0,max_clip_duration: int = 5,
) -> List[str]:valid_video_items = []valid_video_urls = []found_duration = 0.0search_videos = search_videos_pexelsif source == "pixabay":search_videos = search_videos_pixabayfor search_term in search_terms:video_items = search_videos(search_term=search_term,minimum_duration=max_clip_duration,video_aspect=video_aspect,)logger.info(f"found {len(video_items)} videos for '{search_term}'")for item in video_items:if item.url not in valid_video_urls:valid_video_items.append(item)valid_video_urls.append(item.url)found_duration += item.durationlogger.info(f"found total videos: {len(valid_video_items)}, required duration: {audio_duration} seconds, found duration: {found_duration} seconds")
