- Lightweight recorders
- Uncompressed RAW images
- Low processing power
- Large file sizes
The uncompressed workflow allows our clients to make use of lightweight and power efficient recorders like the CoreVet. In step 1, RAW images are written directly to high speed solid state disks as 12Bit Linear files called SIV’s. Up to 12 minutes of uncompressed footage can be stored on a pair of SSD’s. Once the solid state disks are filled, the media is removed from the recorder, and taken by the data handler. Images can be viewed live during capture with a 3D-HD monitor, or later when the footage is being reviewed by a DIT.
In step 2, the SSD’s are taken by hand to an ingestion computer. A copy of the data is made immediately to the array attached to this computer. Checksum signatures are made and compared to the original footage. If the checksums match, the SSD’s are removed from the system and stored for one day before being erased and checked for errors. Copies of the RAW images are made, and shared on the network for playback systems.
*Optionally* At this point the SIV files can be encoded to CineformRAW to save disk space and speed up file transfers, at the expense of some image quality. New signatures and multiple backups of thefootage are made for delivery to the post production facility, as well as safe keeping. The system array is shared and the files are ready to be downloaded to the playback system for QC. Now the files are copied to the playback system in step 3D. The footage is kept here on another array for realtime playback and colour correction.
Q. Why record uncompressed to SSD’s instead of an array?
A. Hard drive arrays have a few major drawbacks over SSD’s. The first and most important is portability. The most common use of uncompressed capture is for situations where you need a lightweight system. Another important scenario to avoid is one where all your digital “eggs” are in one basket. Its important to cycle media regularly.
