Magewell supports video capture and conversion with software
Magewell will show three free software tools to support video capture and conversion when it exhibits at InfoComm 2019.
Its Bridge for NDI enables users to convert source video into NDI streams for live, IP-based production, while version 3.0 of Capture Express records video to files at up to 4K resolution. The third tool, a plug-in for Adobe Premiere Pro CC, provides direct access to Magewell capture devices through the popular non-linear editing software.
Magewell Bridge for NDI allows video and audio from a Magewell capture device to appear as a live source to any other NDI-enabled software and systems on the network. Providing a software-based alternative to Magewell's Pro Convert NDI hardware converters, Magewell Bridge supports all resolutions and frame rates available through the associated capture device -- including Ultra HD video with 4K models. When used with multi-channel capture cards or multiple Magewell capture devices in the same computer, Magewell Bridge can simultaneously convert up to four channels of 1080p video into NDI streams on host systems with enough processing power.
Users can choose to generate NDI streams in the native format of the input source, or can specify the output resolution, frame rate and colour space. Magewell Bridge uses the capture hardware's FPGA-based video processing to perform functions such as up- and down-scaling without consuming valuable CPU cycles. In addition to encoding sources into NDI streams, Magewell Bridge can also receive and decode NDI streams from the network for local preview or full-screen display.
While Magewell capture devices feature compatibility with third-party software for web conferencing, streaming, live production and lecture capture, the Capture Express software offers a dedicated tool for recording or previewing input sources. It was designed to let users verify their input signals and capture devices and has evolved into a capture application supporting video up to 4K at 60 frames per second.
New features in Capture Express version 3.0 include a redesigned user interface; GPU-accelerated H.264 encoding; single-click snapshots of one or multiple still frames; a 'borderless' mode for previewing video spliced across multiple sources; audio level adjustments; and the ability to run up to nine concurrent instances of the software in support of multi-channel cards or multiple devices on one host system. Users can automatically match recording parameters to the input source or use the FPGA-based video processing of the capture device including cropping, scaling and image controls.
The third software offering enables editors to capture video and audio through Magewell hardware directly from within the Adobe Premiere Pro CC user interface, expanding the live production benefits of Magewell's products into the post production domain. Using the same recording core as Capture Express 3.0, the new Premiere plug-in supports GPU-accelerated H.264 encoding as well as the FPGA-based video processing features of the capture devices.
All three new software tools run on the Windows operating system and are compatible with Magewell's USB Capture and USB Capture Plus external devices; Pro Capture PCIe cards; and Eco Capture M.2 hardware. The Capture Express software also supports Magewell's first-generation capture cards and boxes. Capture Express V3 and Magewell Bridge for NDI are available for download immediately, with a beta version of the Premiere Pro plug-in scheduled for release next month.
