OTT 1080 — Youtube自動 1080p 與 H264

在 YouTube、Prime Video 等平台自動以 1080p 播放，並將 VP9 轉為 H264，更省電、更流暢。

OTT 1080 是一款為串流觀看體驗設計的 Chrome 擴充功能，協助你在 YouTube、Prime Video、Hami Video 等平台套用偏好的播放畫質，並在 YouTube 上提供編解碼器偏好設定，讓播放更穩定、更省電、更符合你的裝置需求。 主要功能： 自動畫質偏好：可設定 1080p、720p等 或自動模式，影片播放時會依平台可用選項盡力套用。 YouTube 編解碼器控制：可封鎖 VP9 / VP8 或 AV1，優先使用 H.264，降低部分裝置上的 CPU 負載與耗電。 多平台支援：支援 YouTube、Hami Video。 簡單易用：工具列彈出視窗可快速開關與調整畫質，完整設定頁可管理各平台與編解碼器選項。 偏好同步：可在同一 Chrome 帳號的裝置間同步。 為什麼你應該安裝 OTT 1080？ 如果你常看線上影片，並希望每次都能更穩定地使用偏好的畫質，OTT 1080 可以省去手動切換畫質的麻煩。對於筆電或較舊裝置，H.264 通常更容易由硬體解碼，有機會降低耗電、減少發熱，並改善播放流暢度。 隱私方面，OTT 1080 不蒐集個人資料、不追蹤瀏覽紀錄、不使用分析或廣告 SDK，也不向外部伺服器傳送資料。所有功能皆在你的瀏覽器本機執行。 注意：實際可用畫質仍取決於串流平台、影片來源、DRM 授權與瀏覽器環境。本擴充功能不破解 DRM、不繞過付費牆，也不保證所有影片都能達到特定解析度。 ---- OTT 1080 is a Chrome extension designed to improve your streaming viewing experience. It helps apply your preferred playback quality on platforms such as YouTube, Prime Video, and Hami Video, and provides codec preference settings for YouTube to make playback more stable, more power-efficient, and better suited to your device. Key features: Automatic quality preference: Set 1080p, 720p, or auto mode. When a video plays, the extension will do its best to apply your preference based on the options available on each platform. YouTube codec control: Block VP9 / VP8 or AV1 to prioritize H.264, which may reduce CPU usage and power consumption on some devices. Multi-platform support: Supports YouTube and Hami Video. Easy to use: Quickly enable or disable the extension and adjust quality from the toolbar popup. The full settings page lets you manage platform and codec options. Preference sync: Sync your preferences across devices using the same Chrome account. Why should you install OTT 1080? If you often watch online videos and want to use your preferred quality more consistently, OTT 1080 saves you the trouble of manually switching quality every time. For laptops or older devices, H.264 is often easier to decode with hardware acceleration, which may help reduce power usage, lower heat, and improve playback smoothness. Privacy-wise, OTT 1080 does not collect personal data, track browsing history, use analytics or advertising SDKs, or send data to external servers. All features run locally in your browser. Note: The actual available quality still depends on the streaming platform, video source, DRM authorization, and browser environment. This extension does not crack DRM, bypass paywalls, or guarantee that every video can reach a specific resolution.
