Automated Excellence

Providing the best video experience on any device.

Although it is just a theory in astrophysics, it is a reality for Cinnafilm clients and partners. Tachyon give users access to high quality format and standards conversions tools, elevating their regular transcodes to Tachyon powered Standards Transcoders™.

Cinnafilm’s patented, GPU-based algorithms in Tachyon are the replacement for dedicated, SDI hardware converters that broadcasters and post facilities have wanted for years. Available as both an appliance and a plug-in, regardless of your needs, there is a version of Tachyon right for you.

Standards Transcoding® (performing a standards conversion during a transcode) many simultaneous files at near real-time speeds on a single server was impossible before Tachyon. Some transcoding companies attempt standards conversion while transcoding, but at 5‐8 times slower than real time, and only one conversion per server, economies of scale will never be realized. Other transcoding companies have “bolted-on” legacy SDI hardware-based standards converters in an attempt to make files flow in a Frankenstein-like fashion, but the end result is a long trip to/from baseband, and one conversion per server.
 

Benefits

Tachyon was created from the ground up for file-based workflows and leverages both CPU and GPU to provide unparalleled performance with both vertical and horizontal system scaling. There is not another transcoding/conversion product in the market that can match the speed and scalability of Tachyon.

Tachyon eliminates transcode failures associated with:

  • Broken 3:2 pulldown cadence
  • Intermixed field dominance
  • Intermixed video mode
  • Composited cadence errors

In addition, Tachyon provides industry leading:

  • Compressed file support
  • PAL/NTSC conversions
  • Image scaling
  • Noise reduction via Dark Energy plug-in

Performance

Using the latest generation NVIDIA Kepler-based GPUs, Tachyon is capable of greater than real-time processing speeds for each individual Standards Transcoding stream on the appliance.

A single Tachyon Appliance, equipped with 8 Kepler K20x GPUs, can render HD 50i to 59.94i Standards Transcoding projects at a mind-warping 278.4 FPS.

Tachyon rendering functions are fully encapsulated on the GPU, and Tachyon conversion algorithms do not use the CPU for any reason other than moving frames into and out of GPU memory.

The following are single GPU, real-world benchmark encoding metrics for Tachyon in higher performing transcoding solutions (Fermi-based GPU statistics provided for reference):

HD 50i conversion to HD 59.94i

Tesla 2075
15 FPS
Tesla K10
26.8 FPS
Tesla K20
30.5 FPS
Faster than real-time
Tesla K20x
34.8 FPS
Faster than real-time

HD 59.94i conversion to HD 50i

Tesla 2075
13 FPS
Tesla K10
22.2 FPS
Tesla K20
25.5 FPS
Faster than real-time
Tesla K20x
28.9 FPS
Faster than real-time

Of course, all other less intensive conversions such as telecine removal, image scaling, and pattern insertion will run faster than any of the above benchmarks provided above.

Tachyon is available as a standalone appliance and as a plugin for the leading transcoding platforms on the market. Tachyon Appliances are available with up to 8 GPUs in each server, providing up to 16 GPUs to power 16 simultaneous Standards Transcodes in just 4 RU!
