A major US multinational mass media and entertainment conglomerate needed the ability to retime their media assets to fit into specific times in scheduled playouts, they also wanted to retain the best picture quality and audio pitch. Typical program run times are exactly 1 hour, however there is the need to include 5 minutes of advertising within that 1 hour time slot. Using Kronos XF they are able to modify the program run-time to 55 minutes by using the easy duration adjustment menu within Kronos XF and selecting ‘Time squeeze’ without losing any content or quality from the 1 hour original program.
"This sets a new benchmark for the conversion of performance content for digital cinema and films for television and DVD, without ever needing to slow down or speed up again." Virtual Post CTO Jon Lee
The source contentof the 1 hour program is 59.95i with a 2-3 cadence. It is required that the ‘squeezed’ version of the programme retains perfect 2-3. This requirement can be fulfilled by Kronos XF, as a single process. The process can be thought of as three separate processes:
By adopting Kronos XF the customer were able to retime their media assets accordingly allowing for more advertisement slots, no loss of quality and thus leading to higher revenue streams.
A Client has a programme that has a runtime of exactly 1 hour. It is desired to broadcast the content before the 9 o’clock watershed, but there is a 2 minute section that is deemed unsuitable for broadcast at that time. The programme is edited to remove the offending content and hence the duration is now 58 minutes. Using Kronos XF the programme can be stretched to have an overall duration of 1 hour again, so fitting in the original broadcast schedule.
Kronos XF allows for content to change of up to +/- 20% without losing any perceivable quality difference. It can also adapt the audio pitch respectively.
A major broadcaster has a program of 1 hour, the advertisement slots are 20 seconds each and there are 5 adverts planned within that 1 hour schedule. Various customers pay in advance for those 20 second slots, so it is vital the advert slots must not be affected or adjusted in any way, only the program itself.
Kronos XF enables the operator to create advanced workflows by inserting the 20 second slots or ‘protected segments’ first. This can be achieved by integrating with industry leading video editing software such as Adobe Premier Pro. The operator creates the ‘in and out’ points in the editor and exports the ‘marker’ file for use with Kronos XF. Kronos XF reads the file, recognizes the ‘protected segments’ and dynamically disables retiming during these segments.
Kronos XF offers flexible configuration by providing the operator to select ‘target duration’. Setting the target duration to 60 minutes, squeezes the program only and leaves the advertisement slots at 20 seconds. Quality is retained even though timings have been adjusted.
