By "actual evidence" people usually mean evidence that can't be discarded as easily as testimony.
Hard/soft evidence are established legal terms.
Even with a CCTV recording, you can use testimony to cast the CCTV recording in a light favorable to either the prosecution or defense. The circumstances surrounding evidence are weighed in order to come to a verdict or judgement.
Court cases are not about "who has the most incontrovertible proof", they are about convincing a judge or jury of an idea in order to get a specific outcome. Do not underestimate testimony (or really, any evidence that you think is inferior)
