The second one is pretty simple.

Just adjust the color grading. In this case, the white point is not totally bright, but gray, so simply adjust the curves lowering it.

There is a tendency of making videos dark and less contrasted, In my opinion, it is only a trend thing.

The basic idea behind it is that as displays can render brighter whites, in some cases you do not want a too happy image, so you darken it a bit.

In some cases it is actually the result of using a high bit depth file format, like some RAW video.

The first image is trickier to spot.

It also needs color grading, but it has some obvious illumination issues, mainly because it is backlighted, but also it has a white balance too cold, so it needs to be warmed up.

The blurred background is also hard to spot because it is almost totally flat, so you do not appreciate the bokeh.

You could also have used a reflector to better illuminate the face on this backlight situation.

In this case adjusting the curves gives you a better exposition, without making the whites totally white.

You mentioned "sharpness" on your question. The example image is not sharp at all. But sharpness could be related to the lens or the ISO, but do not be too picky on that.

Try using a tripod if you can and a higher ISO if you can.

Normally the "cinematic look" is not done by using a high framerate, 60p, but a lower one, like 24fps. But that is another issue out of the scope of the forum.
