Teranex FAQ

I need to convert between 50 and 60Hz and vice versa in 3G. Will both

units support this?Conversions from a 3G source in one frame rate to another 3G frame rate would require the

Blackmagic Design Teranex 3D. The frame rate conversions at 3G rates require the expanded

processing power available only in the Teranex 3D Processor.

On the Teranex 3D:

Any SD, HD or 3G inputs can be converted to any other SD, HD or 3G outputs regardless of format or

frame rate.

On the Teranex 2D:

Any SD or HD input can be converted to any other SD, HD or 3G outputs regardless of format or

frame rate.

Is 1080i60 supported i.e. is it the same as 59.94?Many people use the terms interchangeably, but, strictly speaking, they are not the

same. Broadcasting in the USA, Canada, Japan, etc. requires frame rates at 29.97 frames/sec, or

59.94 fields/sec. 1080i60 is generally used for computer signals or some consumer devices.

Teranex supports both 1080i59.94 and 1080i60.

.

Is there a way to delay the audio at all within the units?To keep the audio and video in sync, we automatically delay the audio internally to match the video

processing delay. If additional audio delay is needed, it will be possible within the unit, although the

specification for the amount of available delay has not yet been determined for the Teranex 2D or

3D Processors.

How much latency is there when doing a conversion? Or is this

dependent on what to what is being converted?The delay is typically 4 frames through the processor. Audio, time code signals, etc., are also

delayed to match the video processing delay.

Why do I see anomalies in certain panning speeds?

Anomalies seen in "certain panning speeds" are due to the linear interpolation algorithm that

Teranex uses for frame rate conversions. The anomaly can be partially mitigated by use of the "FRC

Aperture" setting in the Video>ADV menu. A setting of 0 is typically used for dramatic scenes, while

a setting of 3 is used for fast motion.

Can the Teranex 2D be used as a legalizer?The Teranex 2D is not a legalizer. It can clip the Luma and Chroma signals, both hi and low levels, but

does not offer the controls of a true legalizer.

Is the Smart Aspect Ratio feature currently functional?The Smart aspect ratio is indeed functional; however, it is important to note that it is only available

during up conversions, when the SD input format is typically 4:3 and the HD output is 16:9.

The Adjustable Aspect Ratio Feature doesnt seem to work. Am I doing

something wrong?The Adjustable Aspect Ratio feature is not available in the first release of software for the Teranex

2D model. At this time we do not have an estimated date for the software upgrade that will include

the feature.

What is the Thunderbolt port for?The Thunderbolt port on Teranex model enables capture and playback through Blackmagic Media

Express and all supported third party applications and NLEs.

Thunderbolt is present on most 2011+ Mac computers and selected Windows machines. See this

document for Windows Thunderbolt support:
