This fixes

- The video file is too large when you only need the sound.
- A transcription or playback tool accepts MP3 but not the old video format.
How to handle it
- Choose the old video format and select MP3 output.
- Convert the file and download the extracted audio.
- Play the MP3 and compare the duration with the source video.
Before you submit
- Only extract audio from videos you own or have permission to process.
- MP3 is lossy, so keep the video source for archival use.
- Check quiet sections and spoken names before submitting the audio.
Choose the right output
Use MP3 when you only need the audio from a legacy video file.
Keep the original video if the file is archival or evidentiary.
Listen for missing sections after conversion, especially in old mobile clips.
