Monetizing YouTube Channel with Videos Containing CC-Licensed Content
No, one offending video won't taint your entire channel.  At my workplace, sometimes the youtube algorithms will mistakenly flag some music to which we own the rights as copyright protected.  When such an event occurs, the video is automatically un-monetized, and we are asked to demonstrate that we have rights to the music. The video still plays, we just don't make any money off of it. The rest of the channel is unaffected.
