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 program and multi-view preview output as well as an analog 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.
HD Switcher
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.
Audio Mixer
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.
Output Modes
The V-1HD features two HDMI outputs, one output always shows your switched program output. The other output (preview) can be switched between program output and multiview of your four sources.
Control buttons
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.
Transitions
There are three buttons for applying transition effects, CUT, Mix (4-types), and Wipe (30-types).
Beats Per Minute Sync
By using the T-Fader bar and the BP Sync button, you can deliver visuals synced to a music performance.
