I have a notebook aspire E15 acer e5-571g-78bf
Intel Core i7 2 GHz
RAM 4 GB SO-DIMM
HDD 500 GB
NVIDIA GeForce 820M
Graphics card memory type DDR3 SDRAM
graphics card memory size 2 GB
USB3 port
E 'enough to capture video from a sony ufocapture a7s in fullhd format? Although there is not a SSD drive?
If so, you would have a capture card for netbooks, it does not matter that it is 4k notebook, I simply the Full HD format?
Very Thanks and best regards
Ferruccio |

There are two format for FullHD.
1920x1080/59.94i (so called 60i, 29.97fps interlaced) -- 1.5Gbps = 200MB/s
1920x1080/59.94p (so called 60p, 59.947fps progressive) -- 3.0Gbps = 400MB/s
and, USB3.0 is 5Gbps = 500MB/s .
So, you can use both capture device and strage(SSD) device on USB3.0,
if the stream is under 250MB/s.
So there is possibility for 59.94i , but not for 59.94p.
There are many USB3.0 1920x1080/59.94i Capture device.
The most famous one is BlackMagicDesign UltraStudio Pro.
But there may be some low cost ones available on each country.
Use these with USB3.0 external SSD strage device that has over 250MB/s writing speed. |

I don't know.
It should work well from the spec, but there can be some in-compatibility always. |
