Only loop part of video, play intro only once

Hi everyone,

for an installation I am triggering cues with OSC commands and am not using the play mode for cues. To make the setup a bit simpler it would be great if I could do the following:

1. OSC message comes in
2. Play seconds 0-1 of the video once (Enter)
3. Loop seconds 1-10 of the video (Loop) until other OSC message arrives

I have two cues that do just that, however, I am not managing to trigger the Loop cue.

I tried using the MadMapper Control with the playback media position as source range. That successfully switches to loop mode and sets the new loop range. However, the video gets stuck at that position then. (I guess the Loop cue is continuously triggered...)

I also tried just changing the loop start and loop end with the MadMapper Controls but that leads to the same result.

Any ideas how to achieve this?

Best
Marten

Loop End must be higher than Loop Start, which is not the case in your cue (looking at your screenshots)
Loop End must be 100%

Thanks for the catch. I fixed that now and I can manually toggle the scenes Enter, Loop and Exit. However, it does not work in a MadMapper Control as it seems the scene is continually re-triggered. Any ideas?

You shouldn't use Media Player channel /movie.move/position_sec to control an "event" type target, it will indeed trigger the scene on each engine frame

ah too bad, so that means mad mapper can't do this at all? and to create logic like this I would need to use an external way to control this?

Personally when I do a project, I use an external timeline like Ableton Live (cross-platform), Vezér (macOS), Chataigne (free, cross-platform). I play the audio from there and add MIDI or OSC to trigger cues or change some parameters with curves. That's quite powerful.
There are always solutions in MadMapper but using a external timeline is better.

Hi Matt,
then I will do it that way. I had hoped that an enter animation would be possible with mad mapper but in most cases you need more control anyways...
