Welcome to TASVideos, a community dedicated to creating and publishing tool-assisted superplay (TAS) videos, which are gameplay demonstrations made with the assistance of emulators and other tools to resemble superhuman playing sessions.


Here at TASVideos, we strive to push games to their limits. The emulators we use allow for undoing mistakes, slow-motion gameplay, and in some cases even utilizing botting and scripts to do our bidding.
Using these tools, we overcome human limitations to complete games with extremely high precision, entertaining our viewers as our players tear through games at seemingly impossible speeds. The end result of this process is simply a series of key-presses which may be performed on the original hardware.
Many of the insights collected during the making of these runs is documented on our resource pages, allowing new players to quickly catch up to our experts. Some of these tricks we use make the games look broken, but we are not breaking the games, just your notion of them.
You are invited to join the hundreds of authors, thousands of registered users, and hundreds of thousands of monthly unique visitors that make up our community, share knowledge of games, provide feedback of TAS videos, and you're welcome to jump in and make TAS movies yourself.

Mission statement is committed to providing the best in tool-assisted speedruns and superhuman play. Our runs are held to high standards, and only high quality runs will be published on the site. We also prefer quality over quantity — a poor quality run will not be accepted whether it is a game new to the site or an improvement to a pre-existing run. Our runs may not be perfect (if that is even possible), but are still high quality and aim to be as entertaining as possible.


We make these movies because they are entertaining to watch, and because we are curious how far a game can be pushed. The process of creating them is also a form of problem-solving and challenge to our intellect and ingenuity.
If a child receives a box containing an expensive toy as a birthday present, it's possible that he'll enjoy the box more than the toy. This is creativity. We're doing the same for these games. Instead of walking on the paths created for us, we create our own paths, our own legs and so on. And we're not listening to people who say "you can't do that!". Just like children.


The movies on TASVideos are created with the help of emulators that have the capability of recording sequences of key presses — it is the key presses that are recorded, and the video and audio resulting from the emulator playing this back is what can be seen through the videos provided on the site.
The emulators involved have been crafted to provide features specifically designed for optimal game play. The most common features are save states, allowing the author to return to an earlier point in the run (and thereby revert mistakes that are made), and the ability to play one frame at a time (known as frame advance), which removes the limitations of one's reflexes. Where even this isn't enough, some emulators allow for programming and 'bots' to further enhance the process.

Minimum System Requirements for Site Browsing

For technical details, the site requires the OS to trust Let's Encrypt as a cert issuer, which leads to the various OS requirements. The frontend Javascript code's browser requirements will match this Can I Use list due to that feature being used by a dependency, the Bootstrap CSS library.

Game playthroughs we create (emulator movies and their encodes) rely on the Fair Use doctrine when being distributed.

For a well-written outside perspective on the TAS phenomenon, check out As Fast as Impossible: 10 Insanely Thrilling Tool-Assisted Speedruns. This article, written by John Teti, goes more in depth about what tool-assisted speedruns are, and which are the top 10 examples that best demonstrate what these runs are about. Anyone being introduced to these movies should enjoy reading this article, which teaches newcomers how the movies are made, and chooses which are the ideal first movies to watch to become exposed to these speedruns.
