It depends of course on the quality of the lesson and how appropriate it is for your level. There are some wonderful video lessons out there and there are some good only for laughs. The danger of video is in thinking you understand something just because you've been exposed to it. Like all learning it requires active participation to make the material stick.
can video lessons are benificial to learn chess
Until 1400 I only watched videos. Just recently I started to solve tactics, analyzing my games, etc...
Depends on how you use them...
If you just sit back and passively watch them one time, then it won't help much.
But if you are willing to invest some time and effort, then yes, the better ones can help quite a lot.
For instance if there are relevant videos on an opening you wish to study, I recommend you transcribe the video to pgn yourself, adding in all the variations and the comments of the lecturer.
Then repeatedly go over the pgn and critically question moves.
If in a position you see more possible options, for moves other than mentioned in the lecture, try to use a database and find (high quality) example games for these lines.
If there are none, you may wish to consult an engine.
Always when you think, "but what will I do if my opponent plays this or that move (that is not explained in the video)" try to find a solution.
If you don't have a personal chess coach, another important thing you can learn from videos is positional ideas. Pawn structures. Plan-finding.
And, of course, the general thinking processes of stronger players.
In that case, the games examined in the video lesson are not that important by themselves, but you can learn how to evaluate and approach a position.
For instance I find the "Evaluation and Planning" Series by GM Melikset Khachiyan here on chess.com to be of great value.
All that being said; not all video lecturers and not all lessons are good. You'll have to find out for yourself which work for you and which are just a waste of time.
