Troubleshooting of NotebookLM
NotebookLM Workaround: Large Video to MP3 Conversion
Problem Description:
The original 2.3GB video file exceeded NotebookLM's strict 200MB limit for local uploads. As stated in their official documentation: "The current limit is 500,000 words per source or up to 200MB for local uploads."[1] (每個檔案大小不得超過 200MB)
Solution:
Use FFmpeg to convert the video to MP3 audio. Result: The file size was reduced to 126MB, successfully meeting the limit.
1. Download & install Download FFmpeg
2. Open the terminal
3. Command Used:
ffmpeg -i input_video.mp4 -vn -c:a libmp3lame -q:a 2 output_audio.mp3
Breakdown of flags:
- -i input_video.mp4: The input file.
- -vn: Skips the video stream (No Video).
- -c:a libmp3lame: Specifies the audio codec to use (LAME is standard for MP3).
- -q:a 2: Sets Variable Bit Rate (VBR) quality. 2 averages around 190 kbps (high quality). Use 0 for best quality or 4 for standard.
- output_audio.mp3: The name of the new file.
