Personally, I use uBlock Origin since it's faster, more efficient, and less biased than Adblock Plus. So, here are instructions on how to add a whitelist rule for a channel in uBlock
- Goto a YouTube video posted by the channel you want to whitelist
- Wait for it to load and copy the text following the
&user=
portion of the URL - Click on the uBlock icon
- Click on the gear in the corner of the pop-up window
- Click on the "Whitelist" tab in the options page
