I just now am finding out about the KMTimeLine component. It is a multimedia timeline control similar to older version of Premiere. It appears to have been released as BETA in 2001 for Delphi 5.0. Nothing further was done with it.
I've Googled and contacted people associated with the control in hope to purchase it or get the source to be able to compile it with current compiler, but no success. My last effort, before re-inventing the wheel, is to reach out to the EE community for help. There was a similar question asked back in 2004 and someone mentioned they had the source and contacted the author for permission to redistribute. The question was marked resolved.
In posting here, I'm hoping for some sort of success as well.
