Roland's V-1HD 4 x HDMI Input Switcher is a portable solution for HD video production that accommodates up to four HD inputs. The inputs each have a frame buffer/TBC so that you don't need to Genlock your input sources together. You can control the switcher manually by using the built-in controls or connect it to a computer or iPad running optional software for electronic control. Select your working resolution and switch between your four input sources. Built into the switcher is a 12-channel audio mixer, which can de-embed and embed audio signals from HDMI.
The integrated T-fader allows you to manually control the speed of transitions, or you can use the take button to actuate your selected transition. The unit features a programme and multi-view preview output as well as an analogue audio input and output. Though small in size, it allows you to perform picture-in-picture, green-screen, and other keying effects and a transform control enables advanced video effects on your footage.
This portable HD switcher supports four inputs of HD video. It allows you to select 1080i, 1080p, or 720p as your input source. Each input incorporates a frame buffer/TBC that allows you to use non Gen-locked cameras as well as play-out devices as video sources. You select the broadcast system (59.94/50 Hz) within the menu. The format selector switch is a global switch that affects the input and output format. However, with the switch in either of the 1080 options, the V-1HD enables input of both 1080i and 1080p signals.
The built-in, 12-channel audio mixer allows you to de-embed audio from the HDMI stream, mix, and re-embed the audio into your output stream. The audio mixer is accessed by a connected PC running the available software.
The V-1HD features two HDMI outputs, one output always shows your switched programme output. The other output (preview) can be switched between programme output and multiview of your four sources.
The soft rubber back-lit buttons allow you to easily see the condition of your switcher, even in dim lighting conditions. Red: Indicates the current source being output. Green: Indicates video source that will be output on next transition.
There are three buttons for applying transition effects, CUT, Mix (4-types), and Wipe (30-types).
