For many of our users, real time video capture or ingest into an avid shared storage environment is a pressing problem that has typically been quite difficult to solve.
If you are running a so called “rigged camera show” where you are feeding say eight or ten or camera capture streams into an OB truck or gallery, and wishing to record the switched and separate feeds directly to disk in an editable format, your options have until now been quite specialist and again quite expensive.
So why not just use Avid software to capture in the first place? Well you could, but wonderful as media composer is, it is not designed for sustained real time capture ( we are talking typically 8-14 hour stretches here or even 24/7 in some types of ‘reality show’ scenarios )
The issue becomes even more complicated if you want to edit this material while it is still being captured. The need to edit the so called ‘growing file’ is not a new one, and various vendors have stepped up to solve this particular problem – with one thing in common a relatively high cost and complexity
Last but not least, you might want to ‘log’ this material on the fly , which again has historically been the realm of very specialist or bespoke live logging systems.
At root6 we have been working with Cinegy to understand how we an solve some of these challenges at a cost that is well below the typical solutions out there- lets look at a few examples and see what a difference the Cinegy approach might make:
Real time ingest into a avid shared environment-
You need to simply ingest real time streams into a shared storage environment that will allow editors to begin working immediately:
Meet Cinegy Capture Pro:
Capture Pro is software only solution that supports third party I/O cards from the likes of AJA, Black Magic Design, and DVS. Crucially, the software supports cards that have more than one input connection or spigot – this means, that on a workstation with decent CPU performance, you can capture from 2- 4 streams (depending on your capture card) from a single system – this obviously reduces cost and footprint considerably.
Also. you have the ability to capture to several qualities at the same time off the same input. This is vital in workflows where there is typically a transcode pass (post capture) to produce not only an editing and finishing quality but an offline quality also.
So how does this work? In Cinegy Capture Pro, each capture station runs a capture service, and a capture ‘service’ is spawned per input, and per card.
Were I to be using a DVS Atomix 2 input card, my capture pro engine would run two services. If I was running with a Black Magic design Quad card, my engine would be running four capture services if required.
Each capture service can be configured separately, for HD and SD, but certain combinations have to be compatible with the video standard itself – i.e I can’t choose to capture PAL and NTSC on the same card for example.
Once the basic services on the engine are configured, the capture is managed through a browser interface- meaning that I can manage my whole ‘fleet’ of capture engines from one remote position, and not necessarily from the machine that I am doing the capture from.
Each engine can also produce a RTP (real time protocol) IP stream which can be opened in a player like VLC for monitoring purposes also- meaning that overall the package is pretty flexible and very cost effective…
So from this capture pass I could produce a DNX 120 Mbit output, an H264 proxy and if I needed to, we could route an identical DNX stream to a separate location – this means that if a disk disaster occurred, that I don’t lose the captured material in all my locations- this ticks the boxes for redundancy on set and backup.
Don’t assume though, that in this scenario you would not make some provision for backup of your material – Backing up to a format like LTO would be essential, or at the very least, having two copies would be an acceptable interim until another instance could be written out to tape.
In the next segment we will look at Cinegy in the context of live logging and avid workflow…
