That will be covered in a VCR service manual. They will probably tell you to sync to the square wave from the head switching, but I usually just set the scope sync on "line" so it syncs to 60 Hz AC line freq. Anyway, once you see enough of them you'll almost instinctively know where to look for that test point to hook to. Some mfgrs used a common name like "TP6" or "RF-TP" across many models.
