how to change playback speed on a live show

Recommended Posts

I am using watchout 6 for live opera. But sometimes live shows timing and video timing does not match. So i need to speed up or speed down the playpack speed on the fly. Is there anyway to do this.

Not sure this is what you are looking for,

it provides support for a user supplied IP control method

to achieve smooth main timeline playback speed changes.

 

Within limits - there is a cluster control only "experimental" function to do this.

The function is only available via IP cluster control (no Produciton machine during playback).

you would need to come up with your own method

of sending the speed change commands to WATCHOUT.

The speed change available is ±20%.

The change value is a floating point number, so it can be as precise as you need it to be.

New value takes effect immediately, any gradual speed change

would need to be generated by the external control method you choose.

VARISPEED — EXPERIMENTAL ONLY

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

authenticate 1

setRate

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).

Hi jfk,

 

What is the command you use to change the timeline rate?

 

Does it works in realtime?

 

Can you do it also for the aux timelines?

 

Thanks,

Benoit.

Hi jfk,

I actually included that info in the first post above, 

but for some reason it appeared as a large white space

  (actually white letters on a white background).

Tried changing the colors, see if it show up now?

 

Does it works in realtime?

 

Yes

 

Can you do it also for the aux timelines?
 
No

...

Do you mean this feature exists since Watchout 3.1.1 or is it a type error?

 

No error, first available with v3.1.1

No

To clarify, the speed setting will affect ALL timelines. So while you can't do it specifically for a particular timeline, the clock speed is a GLOBAL setting. Changing the speed will slow down or speed up ALL timelines. Also, it may or may not work with audio playback, so I'd stay away from using audio in the show if you attempt to use this speed-changing command.

I always wondered if that may be the case.

The feature was introduced when there was only one (main) timeline,

so I was unsure how it effected the others.

 

Thanks for the clarificaiton.

Rather than vary the speed of the video to fit, I'd think of better options for live theatre.

 

One method -

First I assume that the video(s) do not need to 'finish' at a particular point for each scene/act. If they do, then edit another video to start at 'near to' the desired end point.

 

Next ensure the video to played at a particular scene/act is longer than necessary by at least 1-2 minutes. If the speed is not important/visibly annoying, you can use the 'Playback Speed' under Advance Properties of the Media to slow it down and thereby extend the duration.This should be sufficient for most variations between most shows, except perhaps the final show where actor(s) may take 'unplanned for' actions (I have had one who sobbed emotionally at the final scene, and took some time to recover before continuing).

 

Use Aux Timelines, and a higher order Aux Timeline to fade in the next video (either via an opacity tween at the beginning or controlled by MIDI). Being on a higher order, the media in the Aux Timeline will 'cover' the lower order media. After that you can manually stop the lower order Aux Timeline.
