![]() This is more a box for Computer output or HD video capture than for SD video. If you need a TBC for stablizing video, this box will not do that even though the decoder chip has the feature. These are optimized for HD or above capture and SD is secondary. The video decoder is an Analog Device with a TBC feature permanently disabled because that reduces its ability to capture HD video perfectly. sometimes people want a custom resolution to manipulate pixel aspect ratios and this just is not possible with these devices. Not all operating systems support both protocols.Īlso depending on the connection used, SDI, HDMI, DVI, VGA, Component, Composite or S-Video only specific frame capture resolutions are supported. one is essentially "lossy" to keep up with current events, the other is "not lossy" to make sure all data is capture. ISO and BULK are two different USB protocols. For each firmware "mode" (PnP or UVC) there is also a choice of ISO (isochronous) or BULK mode USB protocol which means there are really four firmwares. Lesson from this is that they are not hardware encoder boxes and use the bandwidth of the USB connection, it should not be shared or video frames and audio samples will be dropped. where with the Windows PnP mode you had manual control through the device driver. Things like phase correction are left to the automatic decision of the device. Both the Mac and Linux can use a UVC device as a camera treating it as an unsophisticated frame capture device. Originally they were designed for Microsoft Windows DirectShow 9.0 later they released a firmware version that upgraded them to the UVC device protocol. Which mostly relates to whether they were firmware flashed to work best with Windows or Windows, Mac and Linux. The Gen #1 AIO boxes could be run in PnP or UVC mode. The XUSB means its a USB attached device and the PRO means its part of the PRO "family" and uses the PRO device driver when not in UVC mode. XI100 means it has one capture channel no matter how many of the inputs are attached. While mine is an AIO all that means is (All-In-One) or that it has multiple inputs. I own the Gen #1 XI100XUSB-PRO the name of the device "encodes" its design and purpose. Its is a complex thing to understand these devices, they are expensive and perhaps overkill for most consumers.įirst they have had several generations. Magewell depends upon them for handling tech support and any questions. The company is based in China but has local reps in each country and region that they sell. My experience with Magewell is they are fair "frame capture" devices, but all compression is done on the PC through software. I live in the United States so most of my experience is with NTSC, but I think I could test with PAL60 using a Kramer Format Converter.
