Justin.tv—sorry, cough, I mean to say—Twitch.tv is a live video streaming service.
Broadcast retention changes
After Twitch's acquisition by Amazon, changes were made to how long broadcasts (sometimes called VODs) were retained for viewing on the site. Previously, all partnered accounts had indefinite storage, while standard accounts had storage for a few days. This was then cut down to two months.
Changes To VODs On Twitch
Aug 06 2014 · Engineering, Tech
Our goal at Twitch is straightforward: deliver the highest quality video. This includes the ability to watch video on demand (VOD) on all of our platforms, not just the website.
In order to create a system that supports live and VOD across the globe and on multiple platforms, we need to make significant changes to the way we’re currently storing video. Today, we’d like to discuss what these changes are, why they’re necessary, and how they benefit the entire Twitch community now and in the future.
Looking at Viewership Data
We found that the vast majority of past broadcast views happen within the first two weeks after they’re created. On the days following, viewership reduces exponentially.
We also discovered that 80% of our storage capacity is filled with past broadcasts that are never watched. That’s multiple petabytes for video that no one has ever viewed.
Highlights, on the other hand, have much more value and longevity. Over their lifetime, highlights get 9x as many views as past broadcasts.
As for existing past broadcasts, beginning three weeks from today, we will begin removing them from Twitch servers. If you would like to keep your past broadcasts, we encourage you to begin exporting or making highlights of your best moments so that they’re saved for posterity.
Although most partner accounts have broadcasts deleted after 60 days, there are some exceptions. Most of these are esports tournament channels, but other channels may be excluded for reasons such as being culturally significant. Below is an incomplete list of these exceptions.

Twitch Chat Downloader
Download link: https://github.com/PetterKraabol/Twitch-Chat-Downloader
Software to download the twitch chat of a given twitch VOD, or a selection of VODs by channel. Note that you will want to (at least) use the JSON output to preserve the most information about the chat.
Example command to download the chat:
tcd --channel "AOC" -o "." --format "default,irc,json,srt,ssa" --timezone "UTC" --verbose --debug --log
The output files will be files named after the twitch video ID with the given file extensions.
Download link: https://github.com/Franiac/TwitchLeecher
Software to download the raw .ts segments of a twitch VOD (of a given quality) and combine them, with an optional conversion to MP4.
Example filename template (set in settings) to include all of the relevant information of the VOD in the filename:
By Archive Team
Archives will be made available later as WARC files in the archiveteam_twitchtv collection at the Internet Archive. You can access them by the Wayback Machine, but you'll need search an index to find the media files.
A work-in-progress searchable index is now available!
Renegade Stream Archives
These archives are made in a manual fashion through the efforts of streaming communities. Feel free to expand this list.
- Vinesauce Stream Archival Effort - A crowdsourced effort by fans of the Vinesauce Group to archive 1714 of their streams.
- Klaxa.eu's Archive of The 4chan Cup - An existing, complete archive of The 4chan Cup, starting from the 2014 Autumn Games up till today.
In June 2016, Twitch deleted a bunch of custom emoticons on the grounds of obscenity. (See• • • for details.)
The emotes can be found in the backend at: https://static-cdn.jtvnw.net/emoticons/v1/<id number>/<size> where id number ranges from 1 to 103667(as of 20160622), with no leading zeroes, and size is 1.0, 2.0 or 3.0.
Note: sizes 0.5, 1.5, 2.5, 3.5, 4.0, 4.5 and 5.0 are valid as well, but return the same data for most(all?) emotes as the next highest available 'whole number' or the largest below that one, i.e. for 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, will match 1.0, 1.0, 2.0, 2.0, 3.0, 3.0, 3.0, 3.0, 3.0, 3.0 respectively)
All emote graphics and sizes (but not their associated chat 'shortnames' i.e. "<3" for emote #9, which cannot be easily determined) still existing in the backend system up to emote id 103667 were archived through Archivebot here; the resulting WARCs can be downloaded through the viewer.
