You cant apply these kinds of compression to a video file in MATLAB. VideoWriter supports writing to H.264 encoded MP4 files. You can adjust the quality setting. Thats it!

You can apply those kinds of compression in MATLAB -- you just cannot use VideoWriter to do so.

Writing H.264 or related code as MATLAB source is a bit long and tedious, and it is usually much easier to find external libraries that do the work.

For a small discussion of H.265 in MATLAB see https://www.mathworks.com/matlabcentral/answers/260310-h-265-hevc-support-in-matlab-2015
