The linked video shows a technique for making the best of a poor situation. Note that the workpiece is relatively thin and extended relatively far from the vise jaws.
You should avoid this setup whenever possible.
To exaggerate his point, the machinist is using a 6" diameter face mill.
When the workpiece is traversing the cutter's center, notice how the workpiece pounds/sings with only a .040" depth of cut (DOC).
That sound is bad and an indication you need to change something.
When the workpiece is traversing near the cutter's outer edge, notice how quiet it is, even with the DOC increased by 6x (.240").
That 'quiet' indicates that you're getting away with the poor setup.
The tip is equally valid for less precarious workpiece/workholding/cutter combinations.
The technique would would be just as beneficial using much smaller cutters.
