The afternoon you don't get back那個拿不回來的下午

Premiere's built-in sync never quite works. Other tools want every track hand-assigned. Premiere 內建的同步功能,從來沒真正對準過。其他工具要你先手動把每條軌道分配好,才肯動。

You shot a 5-cam interview, a documentary, a podcast conversation. You sit down — and the cut hasn't started yet. AutoSync is the bit between "I shot it" and "I'm cutting". 你拍完 5 機位訪談、紀錄片、Podcast 對談,回到剪輯桌前,卻發現剪輯還沒開始。AutoSync 就是「拍完」到「開剪」之間,那塊每個人都討厭的工。

The 60× speedup快 60 倍的差距

What used to be an afternoon, in one drop. 原本花一個下午的工,變成一拖。

How it works使用流程

Three steps. Zero track assignment. 三步。不用分配軌道。

01
drop

Drop the folder拖入素材夾

Organize by source — CamA, CamB, audio recorders, drone audio each in its own subfolder — then drop the whole session folder onto AutoSync. 各素材依來源分子資料夾 — CamA、CamB、外接錄音機、空拍機音訊各自一夾 — 整個 session 母資料夾拖到 AutoSync 視窗上。

02
analyze

Hit Sync按下 Sync

PHAT runs phase-correlation across audio tracks. Drift compensation kicks in. Audio recorders align to each other first, then anchor to video. PHAT 在所有音訊軌之間做相位相關。漂移補償自動啟動。外接錄音機先互相對齊,再錨定到視訊軌。

03
cut

Drop XML into Premiere把 XML 拖進 Premiere

Out comes an FCP7 XML. Drop it into Premiere Pro or DaVinci Resolve and start cutting. 輸出 FCP7 XML,直接拖進 Premiere Pro 或 DaVinci Resolve,立刻開剪。

What you get實際畫面

Five screens, one drop. 5 個畫面,1 次拖入。

From the moment you drop the session folder to the moment you drag the XML into Premiere — every screen, exactly how it looks on your Mac. 4 cameras, 7 clips (some with mid-shoot stops and restarts), one continuous audio recorder. 從拖入素材資料夾到把 XML 拖進 Premiere,每一個畫面都是你的 Mac 實際看到的樣子。4 機位、7 個 clip(有些拍到一半停了、再開),一支錄音機整場跑滿。

What's inside內建的東西

Built by an editor who got tired of nudging clips. 剪輯師自己受不了,寫給自己用的工具。

Any number of cameras不限機位數量

2 cams or 20. PHAT phase-correlation runs across every audio track in the session. Sub-second precision, no manual pairing. 2 機還是 20 機都沒差。PHAT 相位相關會跑過 session 裡每一條音訊軌,sub-second 精度,不必手動配對。

Field recorder handling錄音機原生支援

Rode, Zoom, Tascam. Auto-segmented continuous recordings get boundary overlap detection + auto-trim. Rode / Zoom / Tascam 全支援。自動分段的連續錄音檔,有 boundary overlap 偵測 + 自動 trim。

Per-camera clock drift逐機位時鐘漂移

Crystal drift detected and compensated per source — so 60-minute takes stay in sync to the last frame. 每台機器晶振漂移自動偵測 + 補償。一小時的 take,最後一格也不會 drift。

Recorder pre-pass錄音機專用路徑

Audio recorders aligned to each other first, then anchored to video. Eliminates the subtle echo most tools miss. 外接錄音機先互相對齊,再錨定到視訊。大多數工具抓不到的細微回音,這樣才會真正消掉。

Sony XAVC synthesized TCSony XAVC 合成時間碼

Reads timecode from Sony XAVC even when AVFoundation can't. No more "no timecode track" detours. 就算 AVFoundation 讀不到 timecode,我們也能合成出來。不用再繞路。

FCP7 XML output輸出 FCP7 XML

Drag straight into Premiere Pro or DaVinci Resolve. No round-trip through Final Cut required. 直接拖進 Premiere Pro / DaVinci Resolve。不用透過 Final Cut 中轉。

Edge cases already covered那些其他工具拒絕的素材

DJI drone audio. Audio-only tracks. Long-form 1-hour+ session rescue when other tools time out. AutoSync handles them by default — they're not behind a setting. DJI 空拍機音訊、純音訊軌、1 小時以上長片 rescue — 其他工具會 time out,AutoSync 預設就吃得下,不用開設定。

The actual questions實際會問的問題

FAQ常見問題

Does the footage leave my machine?素材會離開我的電腦嗎? +

No. AutoSync analyzes everything locally on your Mac. Files never get uploaded, and AutoSync doesn't need a network connection to run a sync. 不會。AutoSync 全程在你的 Mac 上分析,檔案不會上傳,執行同步也不用連網。

I shoot Sony A7 / FX3. Will it read my timecode?我拍 Sony A7 / FX3,時間碼能讀嗎? +

Yes. Sony XAVC files often have timecode that AVFoundation can't decode — AutoSync synthesizes it directly from the file structure so the sync still works. 可以。Sony XAVC 的 timecode 有時 AVFoundation 讀不到,AutoSync 會從檔案結構自己合成出來,同步照樣跑。

Premiere or DaVinci Resolve?Premiere 還是 DaVinci Resolve? +

Both. AutoSync writes FCP7 XML, which Premiere Pro and DaVinci Resolve both import natively. No Final Cut Pro required. 兩個都可以。AutoSync 輸出 FCP7 XML,Premiere Pro 和 DaVinci Resolve 都能直接匯入,不需要 Final Cut Pro。

What about my second Mac?第二台 Mac 怎麼算? +

One key activates up to 2 Macs — your own personal devices (e.g. studio + laptop). Switching machines is one click: License Status → Sign out of this machine releases the slot instantly. 一組 key 可以啟用最多 2 台你自己的 Mac (例如:工作室那台 + 帶出門的筆電)。換機只要一個動作:授權狀態 → 登出此機器,額度立刻釋出。

What if it doesn't work for my session?如果對我的素材沒效呢? +

14-day refund, no questions asked, refunded through Gumroad — your license is deactivated automatically. Email service@resonaframe.com if you'd like me to look at the session first. 14 天內可全額退款,無需理由,直接透過 Gumroad — key 會自動失效。如果想先讓我看看 session,寫信到 service@resonaframe.com

Updates?更新怎麼處理? +

AutoSync uses Sparkle for in-app updates. When a new minor version ships, you get a prompt — included for life. AutoSync 用 Sparkle 做 in-app 更新。每次小版發布會自動跳通知 — 終身免費。
