- What is the recording data format?
- noX outputs noXRAW files, which are highly efficient. They are lossless, uncompressed, uninterpolated, easily rendered and previewed.
- What is the typical data rate of recording in 1080/24P?
- The data rate of the uncompressed RAW stream from the camera in 8-bit, 1080/24-fps format is 380Mb/s.
- What happens to my footage if the camera crashes during recording?
- Nothing. The recording is readable up to the moment the power went off.
- Does the noX support audio recording and at what quality?
- Yes, optionally. Audio support is at CD-level recording quality, that is 16-bit, 44.1 Khz. If you want to record on DAT or any other higher quality audio, you need an external audio recording device.
- How much bandwidth/storage is required to make a feature?
- A feature will require between 1 to 2 terabytes for the finished work, depending on your shooting ratio. When shooting in RAW format (1080p, 25-fps, 8-bit LUT, uninterpolated, uncompressed), you would need 178 GB/hr. Multiply this by your shooting ratio to estimate how much storage you’ll need during production.
- How does this storage fit into the principal photography workflow?
- noX can record at least 45 minutes (in fail-safe mode) to on-board disc. If you use the standard mode, you can record 90 minutes of noXRAW footage. If you like, you can backup all data with the noXboX (Digital MAZ for noX) at anytime and even render the footage directly. Material shot in a studio setting can alternatively be connected to a storage network via NAS (requires min 50 MB/s).
- Can noX record to tape or existing 4:4:4 recorders?
- This is not necessary, but 1080p@25-fps recording should be possible via HD-SDI.
- Does noX have on-camera storage?
- Yes. A standard noX package allows you to record 90 minutes of uncompressed noXRAW footage or 45 minutes in "fail-safe" recording mode. Please note that in fail-safe recording mode even if one of the three recording HDD will be damaged in any way your footage isn't harmed at all.
- What about data security?
- noX records on three 2.5” notebook HDD. They are to some extent shock-resistant and much more reliable than standard 3.5” HDD.
If you use the “fail-safe” option (in the software) your footage backs up automatically, so in the unusual event that one of the three
HDD should crash there is no risk of loosing any footage.
As an option we offer completely shock-resistant HDD with a running time around 16 minutes.
After recording to HDD you can backup your footage using the noXboX (Digital MAZ for noX) which uses a RAID 5 server.
Furthermore, any part of your footage on this RAID 5 server can be written to a inserted SATA-drive with one touch at any time.
