AV1

AOMedia Video 1

由 Google、Netflix、Amazon 與 Mozilla 支持的免權利金編碼格式，效率勝過 HEVC，代價是編碼速度慢得多。現在的手機與顯示卡多已支援硬體解碼。

AVI

Audio Video Interleave

微軟在 1992 年推出的容器格式，至今仍常見於老舊攝影機畫面與歷史檔案中。它出現得比串流與可變影格率技術更早，因此轉成 MP4 通常能同時縮小檔案、修正播放問題。

轉換前值得了解的事

AV1 is already lossy, and while AVI can be saved either way, this conversion cannot restore discarded details. Saving it lossless here preserves what is already present instead of discarding more.

FAQ

關於 AV1 轉 AVI 的常見問題

這個 AV1 轉 AVI 轉換器是免費的嗎？

是的。在這裡把 AV1 轉換為 AVI 完全免費，不需要帳號、沒有浮水印，也沒有每日次數限制。處理在你自己的裝置上完成，因此沒有需要轉嫁給你的伺服器成本。

我的 AV1 檔案會被上傳到任何地方嗎？

For browser-based pairs, your file is read locally and converted by ffmpeg in this tab. No file payload is uploaded; you may still see analytics and engine downloads in network logs.

AV1 轉 AVI 有檔案大小限制嗎？

There is no imposed upload cap when it runs in-browser, but each conversion still depends on your device and browser memory. Large videos are the first practical limit, then memory-heavy documents or images.

把 AV1 轉換為 AVI 會損失品質嗎？

It depends on your selected settings and codec path. Many engines can write either lossy or lossless output for AVI, so you can usually increase quality if this file is your final version.

可以一次把多個 AV1 檔案轉換為 AVI 嗎？

Yes. Drop in several files and each gets its own row; they are processed one after another on your device. You can download them one by one or as one ZIP.

AV1 轉 AVI 能在手機、Mac 或 Chromebook 上使用嗎？

Most modern browsers on Windows, macOS, Linux, ChromeOS, Android and iOS work. Very large videos are often more reliable on desktop or a browser with more memory.

Why do some conversions take longer on first run?

The conversion engine has to download first. Small codec bundles are fast, while ffmpeg is commonly 12–30 MB; later conversions of similar type use the cached engine.

I converted a file and the output is blank or unusable. What should I check?

Start over with default settings, then change one option at a time (quality, bitrate, page size, or codec) to isolate what changed behavior. If it keeps failing, retry with a smaller file and confirm the source format matches the pair.
