Digital negative report

When shooting on film, the rushes are sent to the lab, and from there you will receive a negative report on the DMax and DMin levels? film scratches? All that’s measured through optics, and it’s done quickly and efficiently. With digital cinema you can’t produce a negative report without giving it a 100-percent lookthrough. You’re looking at the sensor, you’re looking for shutter errors, dead pixels, and noise patterns, and that has to happen in real time. A digital negative report is essential or the completion of a successful shoot.

The creative advantages for digital are too big to completely dismiss, or discourage. Its possible that a digital production, with all the safety checks required today, that it is just as expensive as film, but the options that digital offers can really bring together ground breaking cinematography and as such open a new wave of possibilities.

Abobe CinemaDNG Initiative

The CinemaDNG file format is designed to store high-resolution video streams in camera raw format and typically adds less than 1 KB overhead per image. CinemaDNG files typically require half the storage space of corresponding DPX files. Each video frame is independently encoded using the DNG (Digital Negative) image format. The video stream is stored either as a picture track in an MXF (Material Exchange Format) file or as a sequence of individual frame files.

CinemaDNG uses fully-documented, vendor-neutral, standard formats for video and imaging – DNG, TIFF/EP, and MXF. The format is unencrypted and free from intellectual property encumbrances or license requirements. Several SDKs are available for each of the components of the format.

The CinemaDNG format allows vendors to add functionality on set or in post, for example, by extending the decoder SDKs with additional image processing or metadata processing.

Arriraw full sensor DPXs

Pure Digital Services can now capture and render the .ari files from the Alexa and deliver full frame 3K DPXs at 2880 x 1620. This allows for more headroom for possible pan & scan within the 3K frame and when re-sized to 2K gives you sharper images.

Pure is now developing workflows for Productions worldwide who want to shoot Arriraw.

Arriraw - D21 & Alexa

How is ALEXA ARRIRAW different from D-21 ARRIRAW?

The D-21 ARRIRAW has the white balance baked in, since back in 2002 we felt that it would be closer to the way film negative behaves. The EI setting is not baked in. The 2880 x 2160 pixel images (4:3 aspect ratio) are transported as 12 bit linear data.

The ALEXA ARRIRAW file format has neither the white balance nor the EI setting baked in. However, both white balance and EI that are set in the ALEXA are stored in the ARRIRAW header as metadata. This metadata will also include other information, including the green/magenta shift value (CC) that has been set in the camera. The 2880 x 1620 pixel images (16:9 aspect ratio) are transported as 12 bit log data, since this is a better way to transport ALEXA's wide dynamic range.

Both file formats can be transported via ARRIRAW T-link. The initial ALEXA ARRIRAW file format has been purposefully kept very close to the D-21 file format (both are 12 bit), since that means only minor modifications to the debayering algorithms used by the recorders and post tools. The recorders and post tools will be able to distinguish between D-21 and ALEXA ARRIRAW based on the metadata, so the whole thing is transparent to the user. In the future, we are planning other ARRIRAW formats to further exploit the capabilities of ALEXA.

Pure Digital supports Arriraw and the .ari file format from Alexa and D21
