Record CinemaDNG錄 CinemaDNG
Record as usual. While you record, two files are written inside the clip's own folder:
照平常錄。錄影的同時,片子自己的資料夾裡會寫出兩個檔案:
\CINEMA\A001_037\A001_037.gcsv | the motion log運動記錄 |
\CINEMA\A001_037\A001_037.json | the lens profile鏡頭 profile |
The log holds every sample the gyro produced, at 2499.466 Hz, nothing averaged. Each accelerometer reading sits on the row of the gyro sample it followed. The profile carries the mounted lens's own distortion — the same curve the camera puts in a DNG.
記錄裡是陀螺儀產生的每一個樣本,2499.466 Hz,沒有平均。 每一筆加速度計讀數放在它之後那個陀螺儀樣本的那一列。 profile 帶的是掛上那顆鏡頭自己的畸變 —— 跟相機寫進 DNG 的是同一條曲線。
Load into Gyroflow and sync載入 Gyroflow 並同步
In Gyroflow, load the frames and both files, then run the sync.
在 Gyroflow 裡載入影格和那兩個檔案,然後執行同步。
You cannot skip the sync, and you cannot reuse a number from last time. CinemaDNG has no timecode, and the log starts about half a second after the first frame — between 470 and 570 ms, and different in every take.
同步不能跳過,也不能沿用上次的數字。 CinemaDNG 沒有時間碼,而記錄的起點比第一個影格晚大約半秒 —— 落在 470 到 570 ms 之間,而且每一次拍攝都不一樣。
Gyroflow asks for a frame rate when you give it a DNG sequence. Enter the rate you recorded at — it cannot read that from the frames.
你把 DNG 序列丟給 Gyroflow 時,它會問你格率。 填你錄影時用的那個 —— 它沒辦法從影格裡讀出來。
If you work in DaVinci Resolve如果你用 DaVinci Resolve
There is a Gyroflow plugin for Resolve, so you can stabilise on the timeline instead of exporting from Gyroflow first. It reads the same two files.
Resolve 有 Gyroflow 的外掛,所以你可以直接在時間軸上穩定, 不用先從 Gyroflow 匯出。它讀的是同樣那兩個檔案。
If you use an adapter or a manual lens如果你用轉接環或手動鏡頭
The camera may not know the lens, or may report the wrong one. The
.json is then wrong, and Gyroflow corrects the picture for a lens you
are not using. The .gcsv is not affected.
相機可能不認得那顆鏡頭、或回報成錯的那一顆。
那樣 .json 就是錯的,Gyroflow 會照一顆你沒在用的鏡頭去修正畫面。
.gcsv 不受影響。
What to do: do not use the .json. Use Gyroflow's own lens
calibration: film a calibration target, and Gyroflow works out your lens's real
distortion and saves a profile you can reuse for that lens.
怎麼辦:不要用那個 .json,改用 Gyroflow 自己的鏡頭校正:
拍一張校正圖卡,Gyroflow 會算出你鏡頭真正的畸變,存成 profile,以後那顆鏡頭都能重複用。
Portrait takes直拍
Nothing to do. In CINE the camera records every frame landscape upright, so Gyroflow reads a portrait take like any other: load, sync, stabilise, and turn the picture at the end of the edit. Leave horizon lock off. Photographs are not touched and still rotate by themselves.
不用做任何事。在 CINE 模式下,相機每一格都以橫向正立記錄, 所以 Gyroflow 讀直拍跟讀其他素材一樣:載入、同步、穩定,剪輯最後再把畫面轉過來。 水平鎖定維持關閉。照片不受影響,照樣會自己旋轉。
