[Craig Seeman] “does not need the same resources of someone sending three different streams”
Is Wirecast Pro able to send three (or four) independent HD streams out to streaming servers, platforms or CDNs, simultaneously?
If not, is there any single device capable of independently (no mixing, no switching) streaming 3-4 HD sources, e.g. from VS-4?
Thanks!

That’s it.

[Jake Deeds] “*If I purchase the Blackmagic Intensity Pro, Will I be able to use all three monitors?”
Yes as long as whatever is on the timeline, is the signal that BMD Intensity Pro supports.

[stig olsen] “I have a PC (z820) and transfered some material (copy/paste) from an external disk to my internal disk.
USB 3 and the transfer speed is only 102 MB/Second.
Is this normal speed? Shouldnt I be able to get a lot faster speed?”This is normal. Modern single mechanical drives (not RAIDed) have transfer rates at between 70 and 150MB/s, depending on how full they are, their rotational speeds, etc. To get faster transfer speeds, you’d need either SSDs or RAIDs (like this) on both ends. The transfer speed will still likely max out at 200MB/s (USB 3.0 limitation.)
To get faster speeds (up to 500MB/s), use either good SSDs or RAID0 arrays over eSATA 6G. Faster than that – the big boys with SAS RAID controllers – or smaller RAIDs with SSDs.
HTH.

[Ben Murphy] “So, I could use an SSD for the OS/Programs. A separate SSD for cache. And a HDD for Footage and media.”
I’d start with one good 512GB SSD (Sammy 840 Pro, Intel 520), assign various folders to AE and PR caching (and possibly previews), and watch how they grow (or not) in size. After a few weeks or months of use, that’ll tell you if you need more SSDs or not.
In favor of this approach:
– Simplicity. Complexity is the enemy of reliability, both in the number of devices, and in the time it takes to manage the configuration. Sharing resources makes a lot of sense; dedicating resources to a specific task (like a whole SSD for just caching) – only when there is a clear bottleneck.
– Sharing resources, reducing waste. Boot/OS/apps and exports don’t need the speed 24/7 – those are occasional uses by nature. Caching and previews on the other hand are much more likely to be used all the time. It makes good sense to use one SSD for both.Not in favor of this approach:
– nothing. 🙂Media – a RAID0 (5,6) of mechanical drives. The number and type of drives depends on desired / required bandwidth. Usually two in RAID0 to start with; if you need larger capacity, faster speeds, better fault-tolerance – something like this plus two of these plus a controller.
Hope this helps. 🙂

[Ben Murphy] “I will be running Premiere, AE, Cinema 4D/Maya, and Resolve.”
What file formats? (As far as SSDs are concerned, what matters is the bandwidth these file will require.)
[Ben Murphy] “I am upgrading to a SSD for the OS and Applications, but I have heard mixed thoughts on whether or not to get SSD’s for the media drive and the Cache/Scratch/Render drives.”
What were the negative considerations in those “mixed” reviews? SSDs are awesome, and more awesome in every way vs. spinning disks, with the exception of value (price per GB). The consideration of limited rewrites is not really in the realm of editing – it’s more in 24/7 maximum IOPS scenarios like database servers.
So usually SSD purchase hinges on identifying bottlenecks, weak spots in your apps and workflow, and putting SSDs where they matter and help the most: boot/OS/apps, AE GPC, Pr cache/database, sometimes one SSD for all of them.
I haven’t heard much of a boost from assigning SSDs to media and scratch volumes.

[Matt Morrison] ” was wondering if I could get away with using the on-board raid controllers on a motherboard to run a RAID0 array “
I almost always use Windows or OSX to drive RAID0: no significant performance issues (RAID0 is light on CPU cycles and memory use), and then there’s the benefit of fault tolerance: if the system goes down, you can take the disks to any other (Windows or OSX) system and recover / work with the data. With the hardware controller, you’d have to take the controller with you – and if it fails, your data is down until it’s replaced.
Other than that, most modern PC mobos have built-in RAID0 support.

[David Cherniack] “Degradation after 5 generations isn’t any meaningful take away at all. The only meaningful degradation is that after one or two generations. Do that test and there’s something worth considering.”
Measuring or viewing degradation over multiple (5+) generations has been a meaningful way to gauge codec’s “lossiness” since the beginning of digital video and graphics.
What’s meaningful to you, is not necessarily meaningful to others.
