Also known as Ramping, Adrenaline Time is a frenetic style of video editing where the action is partly [[{{Undercrank}} sped up]] and partly at normal speed (or [[{{Overcrank}} even slower]]). For example, there could be an EstablishingShot of helicopter footage that is initially at double speed, then changes to normal speed as it approaches its destination. Or, in a historical battle sequence, an attacker's leap could be fast forwarded, then his sword swung in slow motion, then zipping through the stricken enemy's collapse, then showing the next blow in slow mo again, and so on.

See also {{Overcrank}} and {{Undercrank}}. Compare BulletTime for when there's only regular and slow mo action without any fast forwarding. See also CaffeineBulletTime, BingeMontage.

A faithful servant of the RuleOfCool and one the standard techniques for MundaneMadeAwesome.



[[folder: Anime and Manga ]]
* ''Manga/DeathNote'' does it a lot. Who knew [[MundaneMadeAwesome eating potato chips]] could be so epic? Though it should be noted the original manga doesn't do nearly as much.
* Every fight scene in ''LightNovel/SwordArtOnline''. There should be an epileptic seizure warning. [[ This is a mild example.]]
* Omnipresent in ''Anime/FateStayNightUnlimitedBladeWorks'' and Fate/Zero, both by studio ufotable.

* [[TropeMaker Pioneered]] by Sam Peckinpah in films like ''Film/TheWildBunch''.
* Another famous usage is in Creator/MartinScorsese's ''Film/RagingBull''.
* Creator/ZackSnyder:
** ''Film/ThreeHundred'' and all of its [[SatireParodyPastiche parodies and pastiches]]. Done to emulate a comic book panel into the movie.
** And from the same director, Film/{{Watchmen}}.
** And ''Film/SuckerPunch'' too.
* The ''Film/CharliesAngels'' movies. Almost anything directed by [=McG=] would fall in here due to his background as a MusicVideo director.
* ''Film/DieAnotherDay''.
* Used during several action scenes in ''Franchise/TheMatrix'' movies. Examples include characters leaping high in the air and smashing down, and three fights between Neo and Agent Smith: in the subway station in ''Film/TheMatrix'', dozens of Agent Smiths in the "Burly Brawl" sequence in ''Film/TheMatrixReloaded'', and the final battle in ''Film/TheMatrixRevolutions''.
* Used in ''Film/HotFuzz'' during one of the later scenes, when the Heroes have finally broken out the big guns and firing off shotguns at the villagers.
* ''Film/{{Wanted}}'': A heavily worked trope in the film version. The assassins of the story explicitly train in the use of Adrenaline Time and the director loves to explore the visuals.
* Timur Bekmambetov is quite fond of this Trope. See Film/DayWatch and Film/NightWatch.
* ''Film/{{Crank}}'', appropriately enough.
* An example where the audience is not meant to interpret it as the result of editing, but rather as being "real" in the film's universe: At one point in the seventh ''Film/HarryPotter'' film, a {{Mook}} crashes through a window to attack Kingsley Shacklebolt, who hits him with a spell that causes him to slow down, momentarily freeze in the air, then fly back in fast-reverse, with the shards of glass re-forming the window.
* ''Film/XMenApocalypse'': Quicksilver's SuperSpeed scenes are shown this way; he sees everything in slow motion, but the movie will quickly alternate to the "standard perception" of time, which is much faster.
* In Film/Thir13enGhosts, the ghosts rapidly flicker between overcrank, undercrank, normal speed, and reversal when viewed.
* Some of the fights in ''Film/KingsmanTheSecretService'' slow down to appreciate important details or just for RuleOfCool.

[[folder:Live Action TV]]
* MTV does it to speed up action in ''Series/{{Cribs}}'' and ''Series/TheRealWorld''.
* ''Series/{{Survivor}}'' uses it to speed up the action.
* ''Series/CSIMiami'' does this practically every episode with helicopter establishing shots.
* The TV show ''Series/LegendOfTheSeeker'', based on the ''Literature/SwordOfTruth'' novels, feature these kinds of scenes pretty extensively.
* ''Series/{{Angel}}'': The fight scenes started using this trope somewhere in the latter part of its third season.
* The series ''[[Series.SpartacusBloodAndSand Spartacus: Blood and Sand]]'' makes extensive use of this in every single fight scene.
* ''Series/KeenEddie''
* ''Series/BitchinKitchen'':Liberally applied to show the full prepwork and cooking process within seconds instead of minutes or hours.

* "We Need da Money", the first track on Music/DaYoopers' ''We're Still Rockin''', speeds up slightly with each successive line, bumping the song gradually higher and higher by half-steps.
* All over the place in the [[ music video]] for Music/EricChurch's "Homeboy".
* Music/LindseyStirling: The video for "Shatter Me" (featuring [[Music/{{Halestorm}} Lzzy Hale]] on vocals) portrays a slowly spinning porcelain ballerina in alternating slow and rapid motion, symbolizing her frozen outer existence as it intercuts with her inner exploration of her confined world.

[[folder:Video Games]]
* ''VideoGame/{{Achron}}'': A common tactic, since all players have the capability of modifying the rate they travel through time. This leads to players dropping into slow motion during pitch battles to better micromanage their forces, then jumping into fast forward after the battle is over to catch up to the present again.
* Played with in ''[[VideoGame/FirstEncounterAssaultRecon F.E.A.R.]]'' - when the player's "Reflex" ability is activated, everything slows down, but for a half-second after the "reflex" ability is turned off, everything speeds up faster than normal, before "snapping" back to regular speed. Much more obvious with certain {{Videogame Setpiece}}s, especially when Alma is involved. There is one case in ''Perseus Mandate'' where [[PlayerCharacter the F.E.A.R. Sergeant]] is suddenly brought in front of a bloodied operation room: a patient is seen walking towards the Sergeant before stopping in front of a glass door that separates the two of them. The patient's movement was {{Undercrank}}ed.
* In ''VideoGame/FinalFantasyXIII'', [[TheHero Lightning's]] [[LimitBreak Army of One]] uses this. Because you can still input commands while it's going, it also gives you a huge advantage in terms of speed and timing. Kind of an [[InvertedTrope Inverted]] InterfaceScrew.
* ''VideoGame/{{Prototype}}'' uses this during charged attacks and targeting, as well as when you start getting your ass kicked. It's actually quite helpful in both cases.

[[folder:Western Animation]]
* The ''WesternAnimation/SouthPark'' episode "D-Yikes!"
* The ''WesternAnimation/RobotChicken'' segment "1776", in the episode "Moesha Poppins".

[[folder:Real Life]]
* There have been actual experiments to determine if people are able to perceive and process information at a faster rate when stressed. The results have been mixed. It turns out that one study's results show that the effect mostly "is a function of [[ recollection, not perception]]: a richer encoding of memory may cause a salient event to appear, retrospectively, as though it lasted longer." Although it does not increase the subject's capabilities to respond effectively to the event, this effect nonetheless has evolutionary value because it provides a vivid recollection of the details of a traumatic and potentially dangerous event, the better to recognize and react to a similar situation if it is encountered in the future. However, in a strange contradiction, newer research suggests that a [[ focus on performing specific actions]] or an increase in [[ neurotransmitters]], actually does increase information processing, slowing down time perception. In addition, a detailed medical [[ review of several other studies]] done on the topic, including the two above studies, suggests that under certain cases time perception does slow down. Current researchers are still debating exactly how it works but it seems likely that slowed time perception is an actual physical phenomenon experienced at times, not just a function of memory.
