Easy ModeThis option is only good for converting an entire Youtube video into a Webm. I will explain each step as if you were using a computer for the 1st time ever or something like that.
#1 Go to this site:
http://en.savefrom.net(Warning) This site is functioning and
SAFE only with the presumption that you are using all possible safety measures such as running an adblocker and/or a script blocker but primarily using your own judgment as websites of this nature can and will be purchased by someone with malintent who may compromise it. This has happened with another website that performed the same function as this one. A good resource for determining the safety of a site like this is a browser extension called Web of Trust, see here for an example:
https://www.mywot.com/en/scorecard/en.savefrom.net#2 As seen in the 1st OP pic, there is only one option for downloading a webm from this site, it's in 360p meaning that many videos over perhaps 2 minutes in duration will turn out over the size limit of this chan(
8mb), we'll worry about that case in a moment but for now we'll assume you're downloading a video that fits the size limit which you can determine from the 2nd OP pic, so go ahead and click on the webm option in this case.
#3 Finally, we're assuming you're downloading a video that's over the size limit. In this case, you can try clicking on one of the 240p options and checking to see if the filesize is sufficiently low, then you'll need to continue onto the next section to convert the non-webm file into a webm(This should prove still easier than downsizing the 360p webm). If you do download it as 240p, expect a degradation in image quality.
Hardish ModeFirst, I'll briefly explain ffmpeg and dump some links to help you get it
if you're on Linux, it is possible to get it for other platforms but it takes more effort than could be expected from a lazyass like myself so if you're adventurous, google it.
If you're on Windows or Mac, scroll down to the end to find a nifty link that'll give you a neat list of GUI & command line apps for your OS that do the same thing as ffmpeg
