klauskk Posted October 28, 2014 Report Share Posted October 28, 2014 Hello. Does anybody experienced some issues with the Blackmagic Quad capture card? Every inputs works perfectly, but when I use all of them at the same time on the timeline, its just flashing between the input signals for some seconds, and then nothing. When I go back in timeline where I only use one of the input, it works.... Best Klaus K. 0 Quote Link to comment Share on other sites More sharing options...
Moderator jfk Posted October 28, 2014 Moderator Report Share Posted October 28, 2014 This is caused by a common hardware configuration error. Your motherboard is not supplying the needed x4 speed from its PCIe x4 slot. Even though the physical connector may be x4 or x8, it is electrically operating at x1. As a result of the insufficient bandwidth, the card will do one stream, but hits the bandwidth limit for more than one. Even slots that are capable of x4 may step down to x1 when interacting with other PCIe cards (including the graphics card in some cases). Sometimes the solution is as simple as moving the capture card to another available x4 slot that is capable of operating at x4 bandwidth. 0 Quote Link to comment Share on other sites More sharing options...
