Using `bestvideo` only downloads the video track. You need to download audio separately and merge. ### Q: Video resolution is too low? A: YouTube may have regional or quality restrictions on certain videos. Try other formats like `best` instead of `bestvideo`. ### Q: ffmpeg error "No such file"? A: Make sure ffmpeg is installed: `brew install ffmpeg` ### Q: How to specify output directory? A: Pass the second parameter as output directory when running the script, or modify the OUTPUT_DIR variable in the script.
