+- downloading video in specfic format
+  for highest being 480p use
+  `yt-dlp -f "best[height<=480]" <URL>`
+  Make sure to remove the video from that folder too bcz it wont replace it
+or 
+ `yt-dlp -f "best[height<=480][ext=mp4]" <URL>`
+ most of time there r video only for higher reolution so need to be combine audio and video which yt-dlp will do using ffmpeg
+ `yt-dlp -f "bv*[height<=480][ext=mp4]+ba" https://www.youtube.com/watch?v=RZmHlKpDpUU -o output.mp4`
+ or 
+ `yt-dlp  -f "bestvideo[height<=720][ext=mp4]+bestaudio[ext=m4a]/best[height<=720][ext=mp4]" "https://www.example.com/video"`
+ `bv+ba` means best video+best audio
+ It will download video only stream of sometimes webm format but with ffmpeg it will convert it to mp4 anyway
