Every second counts. Time is money.

CablesWe help you keep all the seconds that count, while making your project fit into tight constraints.

At Roundabout, we have the Tachyon® Wormhole™ from Wohler Technologies Inc.
An automated file-based retiming and standards conversion solution, that allows you to win back those precious seconds, so that your video files will fit into tight broadcast scheduling windows domestically or internationally.

Tachyon Wormhole performs a plus or minus runtime adjustment of program content while preserving not only video and audio quality, but also closed caption integrity. With this solution, Roundabout will be able to significantly reduce time-consuming hands-on editing and boost your capacity for delivering program content to meet specific time requirements.

As one of the first companies to invest in this new groundbreaking technology we have the expertise to offer you the best results.
