Detailed Operation Procedure

1. Upload VideoClick "Upload Video" button in the main interface and select the long video file you want to edit.
2. automatic generationOnce the upload is complete, click the "Auto Generate Video" button and the tool will start analyzing the video content and extracting key clips.
3. Edit Video: The generated short video will be displayed in the editing interface, and you can use the toolbar on the left side to edit it, such as editing, adding subtitles, adjusting the volume, etc.
4. Preview and Export: When the editing is finished, click "Preview" button to see the final effect. If you are satisfied, click "Export" button to choose the video format and save it locally.

Steps to Generate AI Video

Converting long video to short video content involves three main steps:

1. Generate transcription: First, we need to download a YouTube video as input. We will use the Pytube library to download the video. Once downloaded, we need to generate a transcription of the video. We will use a locally installed Whisper model for this task. If your system is underpowered, you can use the Whisper API.
2. Identify highlights: Once the transcription is complete, we need to identify the highlights from the video. We will use the OpenAI API to find the hot clips in the video with specific cues. By setting Temperature > 0, we can get different highlights each time we run the script. Once we get the start and end times of the selected highlights, we can use the Moviepy library to edit the video accordingly.
3. Automatic Video Cropping: Next, we convert the highlight video to a short video format (9:16) by cropping the video to keep the speaker in the center of the frame. Since there may be more than one person in the video, recognizing the speaker requires solving the active speaker detection problem. We can use several methods such as TalkNet, Fast-ASD, etc., but in this paper we will focus on simple heuristics using multiple cues.

common problems

• How do I ensure the quality of the generated video? The tool uses advanced AI algorithms that intelligently recognize high-quality clips in videos to ensure that the generated video content is clear and coherent.
• Does it support multiple video formats? Yes, the tool supports many common video formats such as MP4, AVI, MOV, and so on.
• Can the generated videos be uploaded directly to social media? Yes, the generated videos are optimized for direct uploading to social media platforms such as YouTube, Instagram, and more.
