Yes! I often embed a longer video at a specific start point and I'd love to be able to do this in killer player.

I agree with you Mark. Not just the starting point but also the ending point. Sometimes, with third party long videos, we only want to show a certain segment.

this feature call trimmer, saw another guy request this feature too,

we can trim a video starting point and ending point.

eg a 10 minute video, I just need the important part (perhaps the step by step part) which only start at 3 minute 14 second until 7 minute 34 second.

Any thing before and after I don't want to display to my visitor

(FYI, this feature available in wordpress, affiliate video, killer might want to explore this plugin and steal some ideo from there)
