Changing Video Playback Speed Mid File

[RBrandvik]

Is there a way to adjust the playback speed of a video file mid video that can be triggered from a playback cue

Example: We have a video of trees moving and want to then make it look as if the tress are slowing down to a stop. This is for a live event so rendering the slowing down and stopping into the video file is not an option for us.

There is an undocumented experimental cluster control command that allows interactive adjustment of playback speed. It would require a control system to achieve any useful function. This adjustment effects all playback (i.e. the timeline speed is adjusted, not just an individual piece of media's playback speed). The experimental function is limited to ±20%, which may not be able to achieve what you describe. And keep in mind, this function is cluster mode only, it is not available when watchmaker is online.

VARISPEED
EXPERIMENTAL ONLY

A new experimental command has been added to the display cluster protocol for WATCHOUT 3.1.1:

setRate <float>

where the rate must be a value in the range of 0.8 through 1.2, 
allowing for a +/-20% "varispeed". 

Note that this takes effect immediately, 
so any "graduality" would have to be created elsewhere. 
Audio among the media being played by WATCHOUT
 will probably not sync very well (if  at all), 
but visuals seem to be quite OK (including various forms of video).
