    因應google收購twitch之後,公佈更新twitch實況重播檔政策如下:
    為了提倡使用者將重播檔剪接並編輯上傳至YouTube串流影音平台,twitch取消所有會員實況重播檔永久存檔功能,普通會員僅能存3天至最多14天,而合作夥伴或付費會員等使用者,最多獲得60天的存檔重播。

    QK小提醒:請各位實況咖實況主們,盡可能開始配備您心愛的重播檔,避免發生悲劇!手動將影片設為焦點並不在此規範中。

    Changes To VODs On Twitch
    Aug 06 2014 · 262 comments · Engineering, Tech
    [UPDATE 10:50 AM PT]: We need to temporarily disable the YouTube Exporter so that we can resolve increased capacity issues. The fix will take a day and should be ready for use again tomorrow.

    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.


    VOD: Past Broadcasts and Highlights

    First, some language clarification. Twitch VODs include both past broadcasts and highlights. After you finish your live broadcast, the complete broadcast is saved in Past Broadcasts. Historically, we’ve offered you the option to save a past broadcast forever.

    Past broadcasts can also be edited into Highlights and watched on the website or exported to YouTube for promotional use. Currently, a highlight cannot exist without saving the entire broadcast as well.

    Shortcomings in the Current System

    The current system has a few notable limitations:

    VODs are saved in FLV format, and platforms like mobile and console devices can’t playback that format.
    As past broadcasts are saved in 30-minute chunks across multiple media servers, a single server maintenance or failure could prevent proper service of an entire VOD.
    Extremely limited availability of transcodes on VODs.
    Due to current storage requirements, past broadcasts can only be saved for 3 days without an explicit “save forever.”
    We must save an entire past broadcast indefinitely if a highlight from it exists.
    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.

    Y axis represents % of total views for an average past broadcast.
    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.

    Here’s the New Deal

    This data, along with feedback we’ve heard from the Twitch community, made it obvious that our VOD system needs to be improved. Today, we start to move in that direction with an update to how we manage your VODs.

    This update is the first step in a process to build features that you’ve asked for:

    Better VOD quality of service for our international viewers.
    Ability to watch VODs on mobile and other platforms.
    Secure storage of your past broadcasts (with triple redundancy, we make three copies of your past broadcasts).
    An easier way to export highlights of any length to YouTube.
    A step toward conceptualizing new features like DVR, matching quality options from live to VOD, and better VOD discovery.
    Going forward, we’re increasing default rolling storage for past broadcasts from 3 days to a maximum of 14 days, for everyone who has opted in (i.e., enabled Archive Broadcasts). For Turbo subscribers and members of the Twitch Partner Program, that storage is increased to a maximum of 60 days.

    Unfortunately, increasing the amount of storage this way comes at considerable cost. In order to enable this, we have to remove the “save forever” option entirely for past broadcasts. Given the viewership patterns on past broadcasts, we believe the tradeoff is better for everyone. To be clear: this is not a move to economize on space. Due to the triple redundancy, it will actually require us to substantially increase our total amount of storage.

    Highlights will be saved indefinitely; however, they will now be limited to 2 hours in length. All prior highlights that you’ve made will be saved regardless of length.

    其實也不能這麼說
    Twitch本身就內建上傳到YouTube的功能了
    雖然上傳到YouTube要多一個步驟
    但是上傳後就可以永久保存
    而且還有機會供人觀看

    若是成為Freedom! Partner的話
    還有可以賺取收益
    這是在Twitch上沒有的功能

    再者
    原來的Twitch其實也沒有真的永久保存VOD檔案
    機制不清楚
    但是長時間沒人點閱的話
    仍然會被刪除的
