How to download certain quality of a YouTube playlist?

[santosh]

I literally know how to download a playlist a video, it's something like:

youtube-dl --playlist-start [start index] --playlist-end [end index] [url of playlist]

That I suspect downloads the highest possible quality of videos.

Suppose I know that 1080p is the highest quality which user is uploading it's video. What if I want to download all the playlist in 480p?

you can read here about how specify the formats to download: https://github.com/rg3/youtube-dl#format-selection.

I want to download all the playlist in 480p?

this is the simple answer:
youtube-dl -f '[height<=480]' --playlist-start [start index] --playlist-end [end index] [url of playlist]

The answer provided by @remitamine should work, therefore I'm closing the issue.

Note: it's [height<=480], not [height<=480p]
