fpSup-OG2K

Install安裝

1. Check the camera確認相機

   SIGMA fp (not fp L) on firmware Ver.5.02 exactly. How to check.

   SIGMA fp(不是 fp L),韌體必須剛好是 Ver.5.02。怎麼確認。

2. Build the card in fpSup-Merge在 fpSup-Merge 做卡

   Open fpSup-Merge with fpSup-OG2K ticked. You can add other products, but not OG3K: the resolution menu holds three entries, and both OG2K and OG3K take the third one. Download the zip.

   打開已勾好 fpSup-OG2K 的 fpSup-Merge。 可以再加其他產品,但不能加 OG3K:解析度選單只有三個欄位, OG2K 和 OG3K 佔的都是第三個。然後下載 zip。

3. Copy to the card and start the camera複製到卡上並開機

   Unzip it. Copy AutoRun.txt, fpSup.BIN and the FPSUPUI folder to the top level of the SD card the camera starts from. Put the card in and turn the camera on with the USB cable unplugged. Details.

   解壓縮。把 AutoRun.txt、fpSup.BIN 和 FPSUPUI 資料夾複製到相機開機用的那張 SD 卡的最上層。 插卡,拔掉 USB 線再開機。詳細說明。

   The fpSup logo appears in the top left and four boxes fill one by one. All four white means it loaded; the camera's own screen comes back two seconds later. If the boxes stop filling, the load stopped there — see the table below.

   左上角會出現 fpSup 標誌,四個方格一個一個填滿。 四個都變白就是載入完成,兩秒後相機自己的畫面會回來。 方格停住不再填,就是載入停在那裡 —— 見下面的表。

   This happens on every start while the files are on the card. Nothing is written to the camera's flash. Optional Fast Start 2 is a setting on the fpSup-Merge page, not part of this product — see the general guide.

   只要檔案還在卡上,每次開機都會這樣。相機的 flash 不會被寫入。 Fast Start 2 是 fpSup-Merge 頁面上的選項,不屬於這個產品 —— 見總指南。

Before you shoot: card speed拍之前:卡的速度

OG2K is the open gate mode for people who want to stay on SD. At 24p 12-bit it needs 98 MB/s, which is essentially the camera's own FHD rate (97). So the test is simple: if your card records normal FHD cleanly, it records OG2K at 24p.

OG2K 是給想繼續用 SD 卡的人的 open gate。24p 12-bit 需要 98 MB/s, 基本上就是相機自己的 FHD 碼率(97)。所以判斷很簡單: 你的卡能乾淨錄一般 FHD,就能錄 24p 的 OG2K。

Higher frame rates need more. One frame is 4.06 MB at 12-bit, 3.39 MB at 10-bit and 2.71 MB at 8-bit.

格率越高需要越多。一格在 12-bit 是 4.06 MB、10-bit 是 3.39 MB、8-bit 是 2.71 MB。

At 24p 12-bit a 94 MB/s card is already running flat out. It works because the camera buffers, but only short takes have been recorded so far. A faster card, or 10-bit or 8-bit, gives you room. If the card is too slow, the camera stops recording after a few seconds. The storage benchmark measures your real speed on the camera.

在 24p 12-bit 下,一張 94 MB/s 的卡已經是滿載。 它能動是因為相機有緩衝,但目前只錄過短片段。換更快的卡、或改用 10-bit / 8-bit,就有餘裕。 卡太慢的話,相機會在幾秒後停止錄影。 儲存 benchmark 會在相機上量出你的真實速度。

Use使用

Set the recording format to CinemaDNG. OG2K only works in CinemaDNG: switching to MOV withdraws it, switching back brings it back.

把錄影格式設成 CinemaDNG。OG2K 只在 CinemaDNG 下有效: 切到 MOV 它就退出,切回來它就回來。

Then choose OG2K in the camera's normal menu: MENU → recording → resolution, or Quick Set → RES. Choose the frame rate and CinemaDNG quality (8, 10 or 12-bit) as you normally would.

然後在相機一般的選單裡選 OG2K: MENU → recording → resolution,或 Quick Set → RES。
格率和 CinemaDNG 品質(8、10 或 12-bit)照你平常的方式選。

What you get:

你會得到:

2016×1344 is the full 6064×4042 sensor reduced by three. It is not a crop. All eight frame rates, including 100p, use the sensor's quiet readout (sensor mode 139). OG3K has to use the noisier fast readout for its 100p.

2016×1344 是整個 6064×4042 感光元件縮小三倍,不是裁切。 八個格率(包括 100p)都用感光元件的安靜讀出(sensor mode 139); OG3K 的 100p 則必須用比較吵的快速讀出。

OG2K is remembered across power cycles. If it was the last resolution you chose and the format is CinemaDNG, the card selects it again after it loads, and the live view comes up 3:2. It is not restored while a recording is running or still being written.

OG2K 會跨開關機被記住。如果它是你最後選的解析度、而且格式是 CinemaDNG, 卡片載入後會自動再選回它,即時預覽一開始就是 3:2。 錄影中或還在寫卡時不會自動還原。

This is a real menu item, so the camera remembers your choice even without the card. That is why removing it has an order.

這是一個真正的選單項目,沒有卡相機也會記住你的選擇。 這就是為什麼移除有一個順序。

What is tested and what is not哪些測過、哪些沒測

Tested on a camera (figures read from the recorded DNG files):

在相機上測過的(數字是從錄出來的 DNG 讀出的):

• 12, 10 and 8-bit all record 2016×1344 with crop 2000×1334 at (8, 5).12、10、8-bit 都錄出 2016×1344,裁切 2000×1334 位於 (8, 5)。
• FHD and UHD are unaffected; switching OG2K → FHD → UHD → OG2K breaks none of them.FHD 和 UHD 不受影響;OG2K → FHD → UHD → OG2K 來回切換,哪個都沒壞。
• Live view while recording matches standby: full 3:2 frame, no stretch, no colour cast.錄影中的即時預覽和待機一致:完整 3:2 畫面、沒有拉伸、沒有偏色。
• In-camera playback opens and plays without freezing.機內播放能打開、能播,不會凍結。
• MOV + REC no longer freezes the camera.MOV 加按錄影不再讓相機凍結。
• OG2K is restored after a power cycle, and a take recorded right after had no dropped frames.開關機後 OG2K 會被還原,緊接著錄的一段沒有掉格。

Not tested — treat every take as disposable until you have checked it:

沒測過 —— 在你檢查過之前,每一段都當作可以丟掉的:

• Highlight headroom and gain at high ISO. OG3K once lost about 2.7 stops above ISO 640; OG2K is expected to behave differently, but it has not been measured.高 ISO 下的高光餘裕與增益。OG3K 曾在 ISO 640 以上少掉約 2.7 格;OG2K 預期不同,但沒量過。
• Shutter angle. No shutter readback has been taken at any frame rate.快門角度。任何格率都還沒讀回過快門值。
• Long recordings. Only short takes have been recorded.長時間錄影。目前只錄過短片段。
• Taking a still photo while OG2K is selected.選著 OG2K 時拍照片。
• Switching CINE/STILL while OG2K stays selected.OG2K 保持選取時切換 CINE/STILL。
• Warm restart and hot reinstall.熱重開與熱重裝。
• The exact release files were not booted themselves; the camera tests ran on a debug build with the same payload plus the USB shell.發行版這組檔案本身沒有開機測過;相機上的測試是用同樣 payload 加上 USB shell 的除錯版跑的。

The full list is in the release README.

完整清單在發行版 README。

Remove — set the resolution back first移除 — 先把解析度改回去

1. While the card still works, choose UHD or FHD趁卡還能運作,選回 UHD 或 FHD

   In MENU → recording → resolution or Quick Set → RES.

   在 MENU → recording → resolution 或 Quick Set → RES 裡。

   

2. Then delete the files and switch off然後刪檔案、關機

   Delete the files from the card, or take the card out, then switch the camera off. At power-off the card writes back every firmware word it changed, so the camera switches off stock. If the camera froze, take the battery out (USB unplugged). General removal.

   把卡上的檔案刪掉、或把卡拿出來,然後關機。 關機時卡片會把它改過的每一個韌體字寫回原樣,所以相機關機時就是原廠狀態。 如果相機凍結了,把電池拿出來(USB 拔掉)。一般移除說明。
