downloaded videos of different formats coming in same size

[ramadivyasri]

Observed that when I download same video in different formats(resolutions) using youtube-dl, the size of the video files are being the same for all. Why is that happening?

Post the full output of youtube-dl when run with -v, i.e. add -v flag to your command line, copy the whole output and post it in the issue body wrapped in ``` for better formatting. It should look similar to this:

$ youtube-dl -v <your command line>

Do not post screenshots of verbose log only plain text is acceptable.

The output (including the first lines) contains important debugging information. Issues without the full output are often not reproducible and therefore do not get solved in short order, if ever.
