First of all - one thing regarding the Datapath cards - they are definitely better, that's correct. But I am not sure that you can fit 2 Datapath capture cards (SDI2 and E2S for example) in the same machine - we couldnt fit E2S and RGBPRO since they are using the same driver and it's official info from Datapath.. haven't really tried with SDI & E2S... yet

 

 

An update - none of the above solved the problem

Processor with 40 lanes... direct SDI camera... sync into the Blackmagic...correct input settings... etc, etc.

 

But finally it will occur that Blackmagic does not work will all motherboards with same chipset from same manifacturer.

 

One more info we've received yesterday from their suppor regarding Ultrastudio 3.,0 Pro - the new USB 3.0 capture cards from the also do not work with many chipsets

Strange. I know we have run three DataPath VisionRGB e2s for a total of six simultaneous 1080p60 inputs.

Our standard motherboard would not handle that,

 but an alternate server motherboard did function correctly.

After we ran the test and confirmed three e2s function,

the customer ultimately cut it down to two e2s cards,

and those are operating as expected.

 

So I am confused that DataPath says you can not run two two-input cards.

Never had issues either with multiple datapath cards. Wether it were two E2S's, E1S's or a E1/2S and a dual or single SDI card combined, the vision software just keeps counting the number of inputs (so input 1 and 2 are of the E2S and 3 and 4 are the dual SDI.

The confusion stems from the fact that the newer series Vision E/AV and Vision RGBPRO does NOT share the same driver.

Vision RGBPRO is EOL:ed and an old analog only card.

To my knowledge, there's no issues fitting multiple cards (2+) in one PC, as long as the motherboard can handle it.

2 or 3 same type cards is OK

2 different types with same driver (E2S and RGBPRO) - unfortunately not

 

Anyway, Datapath are really great with great support.

I'm really confused with the Blackmagic... We've received the info for the unsupported motherboards or USB 3 chipset after we bought the cards

NNinja,

 

Re: Datapath

 

Again, VisionRGB-E/AV/HD4 and VisionRGB PRO/PRO-2 does NOT share the same driver.

http://www.datapath.co.uk/company/partnerships/item/86-Vision-stand-alone-application,-drivers-and-SDK

VisionRGB PRO/PRO-2 needs a PCI-slot, VisionRGB-E/AV/HD4 are PCIe-based.

 

For VisionRGB PRO/PRO-2 one need a separate driver: http://www.datapath.co.uk/downloads/rgbprodownload.htm

This might account for some of your issues.

 

Dataton has run both 3 x VisionRGB-E2s + Vision SDI2 (8 inputs) simultaneously and

4 x VisionHD4 (16 inputs) simultaneously, at Full HD.

 

This should work on a properly configured system, on proper hardware.

 

 

Re: Blackmagic

 

It's unfortunately a well known fact that Blackmagic cards are picky on which hardware it runs properly on.

That has been discussed here many times, here for example:

Hi all

 

A small (and I hope final) update

 

As it was discussed a lot before - the system was configured according to the tweaks. Hardware was not 100% equal to the officially approved but close enough.

As some of you saw in the enclosed video - there were drops also in the video outputs, not only on the capture inputs. We were really stuck and we started thinking that it could be a problem with the Firewire W9100. Today is the first day after the installation that we have more time before the air shows and we decided to come with 3 other hardware systems (old, new and newest, with all kind of other video and capture cards so we can exchange, test, etc).

 

Upon coming the first thing we did was to change the OS - the new machines were with Win 8.1 Pro and we just switched to one of our HDDs with Win 7. I must say we didn't really hope it would work but being "old school" we had to try.

 

Right now almost everything is smooth and easy going. No drops on the outputs (6 FullHD outputs), no drops on the inputs if the input task is pre-initialized.

 

We'll see how it goes in the next days and if it is OK we'll start the long process of dowgrading the Windows.
