A better use of the Trigger function "SetPosition" would be to set it's slider position from the end of the clip, not the beginning. Or add/change to "SetPositionEnd" and "SetPositionStart". When rehearsing a show that has numerous video playback clips of several minutes each, it would be nice to be able to instantly trigger an event that takes the clip to the last 30/20/10 seconds to see the next transition or cue...instead of the awkward scrubbing. This is a feature of some very popular Playback software packages. It would be great to use vMix as video playout device on event shows.

I cant think of any instance in my 30 years of live production that I was ever asked to start "x" seconds into a clip without setting an in point different from the clip start point. I mean, possibly there could be an instance where someone wants to trigger the replay of a clip from a certain point "x" seconds from the beginning as to highlight a music cue or voice cue. But for almost all live shows that have rehearsals, you most certainly would be asked to play the last "x" seconds of a long video clip as to move onto the next transition/shot/cue without the awkward scrubbing. A "SetPositionEnd" trigger would be most useful for rehearsals. As it is now, I cannot showcase vMix as a complete Live Production Switcher to my broadcast and event clients with video playout because I cant seamlessly GoTo"X" seconds before the end of the clip. I had to add the expense of Playback Pro just for that capability during rehearsals...and now the show.
