Powerful video and audio branding with Crystal Vision's latest logo keyer

Publish date:

Crystal Vision has released four new versions of its MultiLogo modular HD/SD logo keyer, designed to show three graphics on a screen at once. The new MultiLogo V132, MultiLogo V132 8G, MultiLogo V432 and MultiLogo V432 8G provide three layers of keying from a variety of internal and external sources, including a 4 GB or 8 GB video store which can hold up to 500 still or animated logos. Features appearing for the first time include extensive audio processing for elaborate video and audio branding (with four group audio handling, audio mixing with dipping and level adjustments, audio cross fading and external AES inputs and outputs), as well as partial presets for improved on air operation.  

The new MultiLogos retain the powerful functionality of the company's previous range of logo keyers. These features include numerous key processing controls, look-ahead preview, clip recording and trimming, Quick Text, the ability to store and name 255 presets, relay bypass protection and the ability to lock the output to an analogue reference to avoid transmission problems. These 100mm x 266mm modules fit in Crystal Vision's standard frames, available in 2U, 1U and desk top box sizes – with the included MultiLogo Control Software making it easy to get graphics on the screen within a few minutes. 

The new versions of MultiLogo include extensive features for playing out audio. These audio features make MultiLogo the perfect branding tool where elaborate audio control is required, making it ideal for any applications where both graphics and audio need to be added to a video signal – from a sound effect accompanying a graphic to a standard voiceover announcement.  

With multi-group audio becoming more common, the new MultiLogo can embed up to four audio groups (rather than the previous single group) into its video outputs. Audio mixing allows this output audio to be generated from a mix of the audio embedded on the video input and a voiceover or sound effect sourced from either the two internal audio stores (ideal for holding pre-determined audio that needs to be played out repeatedly) or from the external AES input which is available on the MultiLogo V432 and perfect for live voiceovers. The voiceover or sound effect can be faded in and out and have its level adjusted, while the main program audio can be partially or fully dipped allowing it to be either mixed with or be replaced by the voiceover. Wav files containing Dolby E bypass the audio processing to avoid damage, with Dolby E cut in at the next frame boundary rather than being mixed in. There are even more audio features available on the MultiLogo V432 variant: audio can be taken from any of its four video inputs and mixed between them, while the video and audio can be cross faded together when cutting from one of the inputs to another. The V432 additionally provides two external AES outputs which can be used for audio monitoring.  

Partial presets is the second big new feature and makes this version of MultiLogo ideal for on air operation. Presets allow engineers to perform complex events within a single remote instruction, with MultiLogo able to store 255 of these presets. With full presets it would be necessary to store a preset for every combination of logos that might ever be required. Partial presets allow the user to select just the individual control blocks that are to be saved and then recalled – making it possible to change just one variable and leave the others unchanged, particularly useful for those live on air. Any number of the following 18 variables can be selected to form a partial preset: Save Ram 1, Save Ram 2, Save Ram 3, Save Ram 4, Save Ram 5, Save Ram 6, Save Key 1, Save Key 2, Save Key 3, Save Video Mixer, Save Audio 1, Save Audio 2, Save AES Input, Save Audio Mixer, Save ANC Output, Save Recorder, Save GPI and Save Engineering. This means that a preset can now be created which will simply fade a keyer up or down, or just change a logo – and that it is now possible to control all aspects of each layer’s operation (logo, position, transparency and so on) without affecting the other layers. The flexibility introduced by partial presets makes it easier for broadcast engineers to integrate MultiLogo into their existing control or automation systems: if a preset is set up with the exact variables required, it can simply be triggered from an automation system.  

Finally, the latest MultiLogo also offers more control options than previous versions, with operation now additionally available from the REMIND-E Ethernet remote control panel and the frame's integrated control panel. The four new versions of MultiLogo are shipping now and replace the MultiLogo V131, V131 8G, V431 and V431 8G.
