Are you sure that hiding the logo is legal?

[Sivakumaran Chandrasekaran]

off course it is not legal. But, we are not making a product. Its just a academic project kind of thing

[Walter Roberson]

The laws about "fair use" or "fair dealing" are not precisely defined in Canada or the USA, but a notion that has been relatively constant is that if there is time to obtain permission then one needs to do so. Academic projects in Canada and USA are not exempt from copyright laws; there has to be a plausible research reason why using a non-copyrighted item was not suitable. Such as producing your own video and interposing a logo on it and working with that.

Cropping should do it.
