(Judy holds up a recorder and hits "replay")
Judy: Actually, it's your word against yours.
When you need rock-solid evidence that something happened or that someone committed a certain act, having it all caught on video (or audio) tape is just about the most convincing piece of proof there is. Even a Villain with Good Publicity won't be able to just wave criticism away when footage of them kicking dogs to death reaches the public.
In fact, the absolute certainty that video evidence provides is such a common trope that subverting it has become a very popular plot twist, usually by revealing that the footage has been doctored, or that the camera angle involved resulted in Not What It Looks Like.
And, yes, the video doesn't have to be recorded on actual tape; DVDs or computer files will work just as well, but old idioms die hard.
- Subverted in Ghost in the Shell: Stand Alone Complex, where the Tachikomas discuss the fact that video footage is practically useless as evidence due to how easily it can be tampered with. Indeed, the Laughing Man's MO relies entirely on this, as he hacks into any recording devices around him (including other people's cyberbrains) and edits himself out of the footage, effectively letting him become invisible.
- In Steven Universe And The Hunters Of Arcadia, the trollhunters go to Beach City to investigate the images of Jamie in his true form posted on Keep Beach City Weird.
- In Monsters, Inc., Sullivan tricks Mr. Waternoose into the simulation chamber, where he unwittingly confesses to planning to kidnap human children for their screams. Mike then reviews the incriminating footage for the CDA agents in the control room.
Mike: You know what? Let's play my favorite part again, shall we?
- In The Incredibles, Dash's teacher suspects that he'd been pulling pranks during class, so he has a camera running to show the principal. But Dash moves so fast that it barely registers on the tape, and it just makes the teacher seem crazy.
- This is how Judy blackmails Nick into working with her — she records him boasting to her about how much his schemes have made, then threatens to run him in for tax evasion (since he hasn't declared any of it) unless he helps her.
- Later, Judy uses her smartphone to record the conversation between Mayor Lionheart and a doctor about the berserk animals, making him look like the one responsible for their disappearance.
- After Judy comes back to Nick after quitting the force, she apologizes to him saying "I really am just a dumb bunny." He records this, then plays it back, saying that he'll let her erase it in 48 hours.
- Finally, it's used again with Judy's pen to record Bellwether's confession.
- The villains of Machete are completely Too Dumb to Live in regards to this trope. Booth is pretty dumb for crucifying a priest while explaining his villainous plan and not bothering to remove the clearly visible security cameras, but the Senator takes the cake for actually asking that someone videotape him while he's committing murder, and actually requesting that he get a copy of the DVD afterwards.
- In Ruthless People, there's a Not What It Looks Like, where the judge they're blackmailing was videotaped having sex in a car, but the Too Dumb to Live cameraman thinks he was killing the girl. The blackmail still works, though.
- Robot Jox. Before he kills another character, The Mole's confession is videotaped, which eventually leads to his unmasking.
- Spies Like Us. Emmett Fitzhume and Austin Millbarge are videotaped while cheating on a State Department advancement test, which leads to them being chosen as expendable decoys.
- The Avengers (1998). Emma Peel is the prime suspect for the destruction of the Prospero Project after the security tape shows her entering and killing people. It was actually her Evil Twin clone who did it.
- Subverted in Judge Dredd. A security cam captures the murder of a crusading newsman by what appears to be Judge Dredd. Instead of the tape proving his guilt, it's pointed out that anyone could obtain a Judge's uniform and appear to be Dredd, so more conclusive evidence is needed - a DNA match.
- The plot of Heist starts when Joe Moore's face is captured on a security camera he wasn't expecting to be there.
- Mannequin: How the inside man for The Rival is found out:
“When I fired this idiot the other day, I decided to replace him with one of those fancy camera surveillance systems. I have Richards and this moron on videotape!”
- Incidentally, the new security officer for The Rival is referred to as an idiot here.
- The Omega Code 2 has the "doctored" variant.
- The entire plot of Strange Days revolves around a murder caught on tape, with the added problem that the murderers are cops.
- The same applies to the forgettable French movie Skate or Die.
- In The Invisible Guest, a bugged ball-point pen is used to record Adrian's confession.
- Mulholland Falls: Alison's gay friend recorded a lot of her liasons at the motel on film through a two-way mirror. Both Hoover and the General are after these film reels because of the potential embarassment they could bring to, respectively, the former's wife and the latter's reputation. It also turns out that Alison had filmed proof of illegal nuclear tests in the desert, which the bad guys killed her for.
- The plot of The Player of Games is triggered by a pseudo-aversion. Thousands of years into the future, video manipulation is so advanced and commonplace that no one would dream of considering videos as proof of anything, because it is trivially easy to produce pixel-perfect representations of anything you want. The eponymous grandmaster is very surprised when he is blackmailed by an unexpectedly advanced drone, and has to learn that there are indeed levels of event-recording that will be accepted as genuine when a sufficiently sophisticated AI vouches for them.
- A very, very nasty example in Dean Koontz's False Memory: a woman, who knows someone keeps breaking into her house and raping her in the night, suspects her ex-husband but has no idea how the hell he's doing it, since she locks her house up tight every night, and it's still locked in the morning. She sets up a video camera in a potted plant and discovers it's her psychiatrist, who's pretty much mind-raped her into granting him complete control over her psyche with a series of code words. Ick.
- In Andre Norton's Plague Ship, representatives of one of the big trading corporations tried to push the Free Traders into giving up a lucrative trade arrangement. They made a not-especially veiled threat of armed attack, mentioning that they were far away from any authorities who might defend the Free Traders. And then J. Van Rycke pulled a small disc out of a belt pouch and commented, "Very interesting. I shall treasure this recording—"
- In No Way to Treat a First Lady by Christopher Buckley, a secret recording of the President and his mistress the night before he died exonerates his wife of murder.
- In Relativity, Sara and Greg have just gotten married when they bump into Sara's old flame, Martin Bling. When Bling finds out Greg is a chef, he mentions that he may want to visit his restaurant one day. Sara mutters under her breath, "Maybe you'll get food poisoning." Ten stories later (and over a year, in-universe), Bling does go to Greg's restaurant... and gets poisoned. His lawyers dig up the security footage of Sara and hire lip-readers to figure out what she said. Oops.
- In Star Wars: Dark Disciple, Asajj Ventress lies to Quinlan Vos, telling him that Count Dooku killed his Jedi Master, Tholme. When Count Dooku captures Vos, after hearing this from Vos, he plays a holorecording showing that it was Ventress who did the deed. It doesn't convince him because Dooku has falsified tapes in the past. Dooku, however, knows that Vos has the skill of psychometry, the ability to experience past events by touching an object, so he makes him touch Tholme's lightsaber.
- Happy Endings has an early episode, with Dave newly moved into Max's apartment, with food going missing. After learning from Alex that Dave sleepwalks, Max borrows Jane's nanny-cam (that she uses to keep an eye on Brad, but that Brad uses to his own advantage) to catching in the act Turns out, there's an artist squatting upstairs in their crawl space who's been stealing the food.
- In the series finale of Seinfeld the Main Characters are arrested because they watched an armed robbery take place and didn't call the police or do anything else to help.

- On Friends Ross and Rachel argue about which of them initiated the sex that resulted in Rachel getting pregnant. Ross insists that it was Rachel who hit on him, and shouts out that he can prove it because he videotaped the whole thing. This does not make the situation better.

- Mathnet: The Karamasov brothers frame George for armed robbery by one of them wearing a George mask and robbing a bank. He stops to make sure the security camera has a clear view of him, even posing straight on and in profile like those pictures they take when the cops book someone.
- In Better Off Ted Veronica turns out to have a tape of the time Ted and her had sex, confiscated off a security guard who apparently had dozens of similar tapes. Ted ends up showing the tape to Linda, not because of the sex (which she already knew about), but because it revealed that the e-mail Linda swore she had sent Ted had been accidentally deleted during the act, explaining why Ted never received it.
- In NCIS episode "Dead Reflection", a suspect is framed by the perpetrator being seen on a security camera while wearing a mask. the victim was killed because she recognized the voice wasn't right

- Eli Stone: One episode featured a baseballer that was charged with murder because a ball he hit had killed a person he hated and the prosecutor claimed the baseballer aimed for the victim. The prosecutor tried to introduce a DVD suggesting he defendant did have the skills to aim but, since the DVD was anonymous, it became inadmissible as evidence for being more prejudicial than reliable. (The prosecutor couldn't prove it wasn't doctored)

So somebody dredges up a recording in which Palmer says that "it's hardly a matter of national security" but he wants to invite her to charity dinner.

- The case specifically created for the DS "Rise from the Ashes" deals with a murder in the evidence room at one point. Said room had a security camera recording everything, but nothing conclusive was seen because a moving thing was in the camera view all the time.
