[[Time Remapping]] is the act of remapping time itself upon a piece of footage. In other words, the act of slowing down, speeding up, reversing, or non-linearly changing the time it takes a piece of footage to play. Changing the flow of time often will (optionally) change the pitch of the footage as well, reflecting the speed change.

=Speeding Up / Slowing Down=

One of the simplest types of time remapping is simply to speed up or slow down footage (i.e. make it go faster or slower.)

=Reversing=

'''Reversing''' is a classic technique where a piece of footage is played ''in reverse''. It's simple, but effective!

~~=Usage=~~

As the process is a bit more technically complicated, more primitive editors may not be able to reverse footage.

==In [[Vegas]]==

Simply right click the video and click "Reverse". That's it!

==In [[Premiere]]==

Right click the video and select "~~time stretch~~". From there, you can set the speed of the footage. To reverse, check the "reverse" box and exit the menu.

==Reversing in incompatible editors==

Some editors, like [[Windows Movie Maker]], cannot reverse clips without special techniques. For these more primitive editors, there is one technique that can be done for a similar effect:

It may seem simple, but based on the size of your clip this process can be very long and tedious. Be sure to save often!

You may also not be able to split clips frame-by-frame; for example, in WMM, frame divisions are only allowed every 2-3 frames, depending on the ~~framerate~~. As a result, this strategy creates a very choppy looking effect (which also makes [[Stuttering]] and [[Scrambling]] particularly difficult).

While much more common in [[YTP]] the "sus" technique is a popular way to add easy comedy to a video. Take a piece of footage, ~~preferrably~~ one word. From there, "cut" it roughly in half, or more ~~preferrably~~, at a vowel. Duplicate this new piece, and reverse the second one. Finally, tack the two on together.

When you're done, you should get something like this:

* "Wow, aren't you ~~suprised~~!"

* "Wow, aren't you surprised!"

* "Wow, aren't you suuS"

The possibilities are endless.

=Non-Linear Time Remapping=

If more needs to be done than simple slowdowns/speedups, time can be remapped manually, usually with a graph editor. Because of this, non-linear patterns can be introduced that can cause the footage to change in speed ''over time''. An example of this is the "spin down" effect commonly associated with a record player stopping.

=Emulating Time Remapping=

Various effects and VSTs exist that can 'fake' the remapping of time without actually changing the speed of a piece of footage.

The "spin down" effect can be replicated using a dedicated button in various VSTs such as [[iZotope Vinyl]] (this will not change the video speed, however.)
