video over ethernet works

[Arnie Schlissel]

But I assume that these systems will only work well with compressed codecs?

IOW, you’re not going to get 10 bit 4:2:2 1080 to play over ethernet, but you should be able to do so with DVCPro HD, ProRes, DNX HD or Photo-JPEG.

you are correct Arnie. However, 10 bit standard def uncompressed is no problem. But no uncompressed HD or 2K.

Tres cool!

What Mr. Zelin fails to mention is that almost all of the solutions
mentioned only work well for a limited amount of seats… usually less than 12.

So, if you have a large number of seats, all pulling HD streams, ethernet may NOT
be your best choice. HD over ethernet works… but in it’s current form it doesn’t
scale well to a large number of seats.

It’s encouraging to see the advances in connectivity that have enabled video over ethernet, but
if you’re specifying a system that’s expected to grow… you need to consider what happens when
your needs exceed the handful of streams currently available via ethernet.

What Mr. Raudonis fails to mention is that with the exception of his market (and NY) the reality of having 100 seats (100 clients) is inconceivable. When I first heard about this type of system, it was being used by O Entertainment in San Jan Capestrano in Orange County, CA. by six editors. My recent installations, for Disney Broadcast Operations and Sullivan Productions, are for 3-4 clients.
12 clients – damn, Pink Sneakers in Orlando is running 15 clients, and for us in hicksville, this is MIND BLOWING. The very fact that anyone can own 15 systems in a “secondary market” is amazing. Of course, in the big leagues (NY and LA), 50 – 100 systems may be typical, but not for this market, and certainly not for this type of system. I spoke with Small Tree when Pink Sneakers was doing 15 systems, and was considering doing more, and they could not believe that it was working. For Mr. Raudonis’ type of system (100 seats), only a fool would think that a simple ethernet AFP system could work. Fibre is a must.

I continue these discussions because I foolishly believe that the typical user that this system appeals to is the 2 – 3 MAC user client, that just wants to have inexpensive shared storage. If we can get 6 – 8 systems working, that is great. If we can get 15 systems working, well, this is a miracle. More than that – forgetaboutit ! And if I am wrong, it will only be Ed Stahr at Pink Sneakers Productions (who just bought the 48 port Small Tree switch) that will prove all of us wrong.

Bob,

I think this will soon become quite commonplace. With the cost of storage continuing to go down, and the cost of ethernet based connectivity continuing to drop, the notion of a “secondary” market having
dozens of systems is NOT that far fetched. That’s actually my point of posting my previous comment.

As price and technology enables a higher number of systems, you have to be careful that the connectivity
you choose can handle the (inevitable) growth. Of course, (anticipating Bob’s response) for the low cost of these systems, you can buy TWO when you need it.

Price and technology has nothing to do with it. You have to have enough work to justify that many seats. I think Bob’s point was that the only places in the USA that have that volume of work are Los Angeles and New York. And, in general, he’s right.

[Mark Raudonis]

[Mike Most] “And, in general, he’s right. “

Don’t agree. What about Vancouver? Atlanta? Chicago? DC? Knoxville? Nashville? I’ve spoke with people in each of these cities that have very large shared storage systems. The price and technology is enabling many shops that couldn’t perhaps justify the “shared work group” environment to now jump into the pool.

Plus, there are so many cable channels out there that the “home base” for many of them is no longer just LA and New York. The work IS spread around the country.

Hmmm. Good point. You’re right, since my perspective is generally network television and features, I often don’t think about the cable networks – a mistake in this case because, as you point out, a number of them are not headquartered in L.A. or New York.

While we’re on the subject, I would now probably add the Spanish language networks, putting Miami on your list.

There are also quite a number of educational facilities in all corners of the country where one may find a number of iMacs for teaching FCP and other tools, where Ethernet is the only network connection option. These also make great inexpensive systems for off-line editing.

Studio Network Solutions’ product EVO provides a multitude of connections, including Fibre Channel for those needing Uncompressed HD, as well as an optional 10GbE uplink port, for capable switches, providing the bandwidth required for multiple systems to stream compressed HD.

From my MacBook Pro 15″ I have handled 3 x streams of PRORES HQ over a single GbE connection to an EVO, ~70MB/sec. Works quite well, of course you’ll need at least 4GB of RAM, but that goes without saying for any edit system in my opinion.
