Troubleshooting YouTube Video Download Errors

1. Verify that the proxy address is entered correctly. The correct format for the proxy address is http://127.0.0.1:port_number. Avoid entering incorrect or random information.
2. YouTube video downloads involve downloading the video and audio as two separate files. These files are then merged into an MP4. If you open one of these files during the download process, it will likely be the video file and therefore won't have sound. Please wait for the download to complete, including the merging process.
