How to remove youtube branding after embedding video in web page?
You can add ?modestbranding=1 to your url. That will remove the logo.
modestbranding (supported players: AS3, HTML5)
This parameter lets you use a YouTube player that does not show a YouTube logo. Set the parameter value to 1 to prevent the YouTube logo from displaying in the control bar. Note that a small YouTube text label will still display in the upper-right corner of a paused video when the user's mouse pointer hovers over the player.
&showinfo=0 will remove the title bar.
showinfo (supported players: AS3, AS2, HTML5)
Values: 0 or 1. The parameter's default value is 1. If you set the parameter value to 0, then the player will not display information like the video title and uploader before the video starts playing.
You can find all options on the Google Developers website.
Note:
It doesn't fully remove the logo. There is still a small logo on the bottom left.
showinfo is deprecated and will be ignored after September 25, 2018: https://developers.google.com/youtube/player_parameters
It turns out this is either a poorly documented, intentionally misleading, or undocumented interaction between the "controls" param and the "modestbranding" param. There is no way to remove YouTube's logo from an embedded YouTube video, at least while the video controls are exposed. All you get to do is choose how and when you want the logo to appear. Here are the details:
If controls = 1 and modestbranding = 1, then the YouTube logo is bigger, is on the video still image as a grayscale watermark in the lower right, and shows when the play controls are exposed as a big gray scale watermark in the lower right. example:
<iframe width="560" height="315" src="https://www.youtube.com/embed/Z6ytvzNlmRo?rel=0&controls=1&&showinfo=0&modestbranding=1" frameborder="0"></iframe>
If controls = 1 and modestbranding = 0 (our change here), then the YouTube logo is smaller, is not on the video still image as a grayscale watermark in the lower right, and shows only when the controls are exposed as a white icon in the lower right. example:
<iframe width="560" height="315" src="https://www.youtube.com/embed/Z6ytvzNlmRo?rel=0&controls=1&&showinfo=0&modestbranding=0" frameborder="0"></iframe>
If controls = 0, then the modestbranding param is ignored and the YouTube logo is bigger, is on the video still image as a grayscale watermark in the lower right, the watermark appears on hover of a playing video, and the watermark appears in the lower right of any paused video. example:
<iframe width="560" height="315" src="https://www.youtube.com/embed/Z6ytvzNlmRo?rel=0&controls=0&&showinfo=0&modestbranding=1" frameborder="0"></iframe>
Youtube have removed the ability to completely remove a YouTube link form an embedded YouTube video.

Even by removing the showinfo section YouTube places a semi transparent logo in the upper right hand corner of a paused video.
