影片格式轉檔卡關?MediaCoder 能幫上什麼忙
你手上有一部影片,格式偏偏是播放器不認得的,或是從手機傳到電腦的檔案太大,想壓小一點再傳給別人。你打開電腦想找個轉檔工具,卻發現線上轉檔網站要上傳下載等半天,免費軟體又常常綁一堆廣告或安裝捷徑。你只是想趕快把檔案轉成能用的格式,不要複雜的設定,也不要等太久。
一般人遇到這種狀況,第一個念頭是上網找免費轉檔軟體,但下載回來的東西常常介面看不懂、操作步驟繁瑣,或是轉到一半就當掉。系統內建的播放器或陽春工具又只能看不能轉。這類轉檔工具的切入點,是讓你在本機直接處理檔案,不經過上傳下載,透過批次處理和細部編碼設定,一次搞定多個檔案,同時保留你想要的畫質或音質。
01MediaCoder 到底能轉哪些格式?
它涵蓋的格式範圍很廣,影片方面支援 MP4、AVI、MKV、MOV、FLV 等常見容器,編碼包含 H.264、H.265、VP9、MPEG 系列;音訊則有 MP3、AAC、FLAC、Opus、WMA 等。另外也支援從 DVD、CD 擷取音軌或影片,以及 Blu-ray 光碟的輸入。基本上日常會遇到的影音格式,它大多都能處理。
02除了轉檔,它還能做什麼?
內建基本的影片編輯功能,可以裁剪片段、合併多個檔案,也能把字幕檔加入影片中。如果你想把一段影片的片頭片尾去掉,或是把兩段影片接在一起,不需要另外找剪輯軟體,直接在轉檔前設定就好。不過它畢竟不是專業剪輯工具,複雜的剪輯工作還是得交給專門的軟體。
03一次轉很多檔案會不會很麻煩?
不會,它有批次處理功能,可以把多個檔案一次加入佇列,設定好輸出格式後一次全部轉換。你不用一支一支慢慢轉,可以先把所有要轉的檔案丟進去,統一設定,然後一次開始。這對一次要處理大量影片或音樂檔案的人來說,可以省下不少時間。
04轉檔速度怎麼樣?有沒有辦法加速?
它支援 GPU 加速,如果你的顯示卡是 Intel HD Graphics 3000 以上或 NVIDIA GeForce GTX 7 系列以上,可以在設定中開啟硬體加速來提升轉檔速度。不過實際速度還是取決於你的 CPU 核心數、記憶體大小和檔案本身的大小。官方建議至少四核心 CPU 和 8GB 記憶體,跑起來會比較順。
05介面好操作嗎?我沒用過這類軟體。
介面是英文的,但設計上算直覺,主要按鈕和選單都標示得很清楚。基本流程就是按 Add 加入檔案,從下拉選單選輸出格式,再按 Start 開始轉檔。如果你看得懂基本的英文介面,照著步驟操作不會太困難。不過如果你完全不懂英文,操作上可能會需要對照一下功能說明。
06這套軟體適合什麼樣的人用?
適合需要經常轉換影音格式、而且對輸出設定有要求的人。比如說你想把影片轉成特定裝置能播的格式,或是想調整位元率、影格率這些細節,它有進階選項可以讓你微調。另外,一次要轉大量檔案的人也會覺得批次功能很實用。如果你只是偶爾轉一兩個檔案,它也能勝任,只是功能對你來說可能有點過頭。
07它是免費的嗎?會不會有功能鎖住?
基本轉檔功能是免費的,但官方有提到存在一個付費的進階版本,提供額外的功能與技術支援。免費版能不能用到所有功能,官方說明沒有明確列出免費與付費的差異,這點需要你自己安裝後確認,或到官方網站查詢。如果你只是要基本轉檔,免費版通常夠用,但進階功能可能會有使用限制。
08它有支援 Mac 或手機嗎?
沒有,它只支援 Windows 系統,包含 Windows 7、8、10 和 11 的 64 位元版本。官方說明中也明確提到它是 Windows only。如果你用的是 Mac,或想在手機上轉檔,這套軟體不適合你,需要找其他跨平台的工具。
09我有一部有版權保護的 DVD,能轉嗎?
不行。官方 FAQ 明確說明它不支援轉檔有 DRM 保護的檔案。如果你的光碟或影片檔案有數位版權管理機制,這套軟體無法處理。這不是設定上的問題,而是功能上的限制,就算強行加入也可能會失敗或輸出異常。
10這套軟體穩不穩定?會不會常常當掉?
官方說明中有提到偶爾會出現穩定性問題和 bug,而且使用者評分只有 6.72 分(滿分 10 分),評分人數也只有 21 人,樣本數不多。如果你要處理的是很重要的檔案,建議先拿一個小檔案測試看看,確認輸出結果沒問題再大量轉檔,避免轉到一半程式崩潰。
11它跟 HandBrake 比起來,哪個比較多人用?
以評分人數來看,HandBrake 有 338 人評分,MediaCoder 只有 21 人,表示 HandBrake 的使用者基數明顯大很多。HandBrake 是開源軟體,更新也比較頻繁。如果你在猶豫要選哪一套,可以兩套都裝來試試看,看哪一套的操作流程比較符合你的習慣,再決定要用哪一個。
12這套軟體還有人在維護嗎?
根據版本紀錄,它近 12 個月內有 3 次更新,近 24 個月也是 3 次,代表開發者仍然有在釋出更新,但頻率不算高。官方說明中也提到缺乏官方支援和更新是它的缺點之一。如果你很在意軟體是否頻繁更新、有沒有官方技術支援,這點需要列入考量。

Topaz Sharpen AI 1.4.0
New Feature:
- Intel Optimization (OpenVino) in.
- Now a new option “Enable Intel OpenVino” is in preferences. If you choose “Yes”, it will optimize Intel CPUs and Intel iGPUs for Sharpen. Typically, it will make Sharpen run 5 times faster than the previous “CPU” mode. But we cannot guarantee if it can work for CPUs from other vendors (e.g., AMD) or any Intel CPUs before 6th generation. If you still have very high performance dedicated GPUs (e.g., NVIDIA 1080), “Enable discrete GPU” (Yes) option will be the best choice. However, if you have relatively better Intel CPUs or Intel iGPUs than low performance GPU, you will see faster performance on Intel optimization (Yes)
- Automatic detection for the best devices choice.
- Now you do not have to choose between GPU/CPU or enable/disable Intel optimization manually. Sharpen will automatically run a benchmark and choose the best preferences settings for you to achieve the highest speed on your computer. The benchmark will only be triggered once when you process the first image. Thus, the first image will take longer time than usual.3.
Change:
- Model update.
- The updated AI is trained with an improved algorithm. For Focus and Stabilize mode, it produces much sharper images than previous versions.
