We have a project coming up that requires a very small footprint, but requires a live input. It seems like the Amba's would be the perfect choice for the job, but our's don't have input cards from the factory. I've looked for information regarding true and tested input cards for the Amba's specifically, but I can't find anything. Can I just use any card on the "Supported Capture Cards" list in the manual, and just make sure to use only one input?
*from the manual:
Supported Capture Cards The following lists supported capture cards:
Data Path VisionSDI2 — Dual 3G-SDI Capture Data Path VisionSC-SDI4 — Quad 3G-SDI Capture Data Path VisionSC-DP2 — Dual Display Port 1.2 Capture Data Path VisionAV-SDI — SDI, DVI and Composite Capture Data Path VisionRGB-E2S — Dual DVI Single Link Capture Data Path VisionRGB-E1S — Single DVI Single Link Capture
The Amba will only certain cards from your list above you can fit the following.
Data Path VisionAV-SDI — SDI, DVI and Composite Capture Data Path VisionRGB-E2S — Dual DVI Single Link Capture Data Path VisionRGB-E1S — Single DVI Single Link Capture Data Path VisionSDI2 — Dual 3G-SDI Capture
I've got the input cards installed (Data Path VisionSDI2) and the Ambas see the inputs. My problem now is frame delay. When I look at my inputs through the Hippotizer software, there is significant delay. I'd say it's around 7 frames. When I check the input directly through the Vision Window software, it's MAYBE two frames. Is there any way to help this, or is this just an inherent property of the signal going through multiple data lanes?
It shouldn't be 7 frames, which Datapath drivers are you using, Different drivers have different delays. You can also try turning off Render buffering, you will find this in the settings cog in the output manager.
Did you find a driver that lessened the delay any better than the others? Currently experience quite a bit of delay myself. Also, did you get any weird errors when installing? I see a WDM Streaming Device Driver Installation Failed. The device instance does not exist in the hardware tree.
Let me know what combination worked best for you if you don't mind!
I DID see those same errors initially, but another try at the install worked.
I had to abort the live input, unfortunately, as I ran out of time. It wasn't an imperative for the gig, so I just used an SDI input into an Image Pro 2 that I had in line as an A>B switch for the live portions.
As tested, I was still seeing ~7 frames of delay with 7.8 and 7.14 drivers. I thought that I had gained a couple of frames until I performed a proper frame delay test.
I'll have some time at the beginning of next week to perform more testing, and I'll post results here.
