Turbo.264UniversalElgato 對 Turbo.264 釋出了更新項目 1.3 版。1.3 版含有新功能和一些程式錯誤的修復。Turbo.264 1.3 的新功能包含編碼與上傳 YouTube、DVD Chapter Marker、Apple TV 預置支援 Dolby Digital AC-3 Audio (若來源是的話),以及 QuickTime Broadcaster 支援以 H.264 進行即時連續撥送。

  • A problem where some iMovie projects lost audio at the end of the clip has been resolved.
  • A problem where encoded files larger than 2 GB had an incorrect aspect ratio has been fixed.
  • Freebox HD recordings exported via the Turbo application now have sound.
  • A problem with WMV files that were truncated or had an incorrect duration after exporting has been resolved.
  • Turbo now supports .avi files with the WRAW codec.
  • QuickTime Player Pro no longer displays multiple blank dialog windows when attempting to export without Turbo hardware.

適用於 YouTube 的編碼:

Turbo.264 是個硬體的 H.264 編碼器 (encoder)。它會將系統資源從 CPU 移轉到 Turbo.264。我們大多喜愛 H.264 的畫質 (請參考 H.264 與其他編碼器的比較頁面),但我們也很清楚 H.264 的編碼挺費時的。
Elgato Turbo.264 可以處理任何 QuickTime 認得的視訊格式,同時包含其他協力廠商提供的編碼器,如 Flip4Mac WMV 元件以及 MPEG Program Stream/System Stream (包含未經加碼的 DVD/HD DVD 內容)。
如果您擁有威力十足的 Mac Pro,Turbo.264 的優勢可能不會那麼顯著。對一般使用者而言,移轉 CPU 的資源可以讓使用者更順暢地運用 Mac 來執行其他工作。
