Canon EOS 77D videos look different?

No camera ever gives a recording of moving images in exactly that way that you eyes see the event, in all circumstances.

If you want a good practical camera with which to shoot video, buy a good camcorder, rather than trying to use any camera basically designed for still photos.

No camera "sees" the same way our eyes do, period.

This is why worthwhile cameras have "white balance" settings you can change ---

and it is why you Must change those settings for different situations.

Cameras NEVER did take pictures that looked the same as with human eyes. It never did with film and it doesn't either today with digital.

The same goes with videos and movies.

This is actually a good thing. Why? It allows good photographers to make something (or someone) look BETTER in pictures.

You need to calibrate the LCD of your Canon camera.  Canon has gotten their good reputation regarding video among DSLRs not from their low or mid-level cameras like the 77D. They got it from their high-end models like the 5D Mark III/IV or 1DX.  Panasonic's GH4/5 and Sony A7S or A9 are far better.  But none are as good as a camcorder which is purpose-built device specifically for video.  

Also, if you haven't already, download the Magic Lantern firmware upgrade which adds a lot of videocentric features.

Furthermore, no camera see exactly the same way the human eye sees - they simply cannot.  Now, if you're just talking about exposure, then that's a different story.  But in terms of contrast and color, no camera sees the same way that the human eye sees things.

Finally, if your primary use of the camera is video, then get a camcorder which is a whole lot better and easier to use than a DSLR that just so happens to have a video feature for convenience.  Canon dumbs-down the video features in their DSLRs so as to not hurt their camcorder sales.  The Magic Lantern upgrade fixes some of these issues, but it's still nothing like using a dedicated device that is specifically designed for video.  And if you need to make a photo, camcorders can make 8MP images which is large enough for a 5x7 or 8x10 print, and certainly good enough for a 4K monitor or social media.

Use a camcorder for video.

A DSLR is a still camera that has the ability to take videos.

Always use the proper tool for the job.
