I have decided to do a little post about this Isadora actor as I use it a lot and is particularly useful in controlling events.
I often find that clients/students need to play a video but then need effects/sounds/switches/other ‘events’ to happen at a particular time; for instance at 1:33 we need the blur actor turned on and then at 1:55 we need it turned off again.
There are two simple ways of doing this 1) By a human 2) Automated.
1) I will not describe the first way as I literally mean – A human triggers the event via keyboard/mouse/other trigger, so…
2) By automation. Not quite the same as automation in Logic/Cubase/Pro Tools etc but similar. This is how you do it…
The movie player gives you a reading of “0 – 100” (as a percentage) to show the position of the video. The longer the video the slower this reading will do, the quicker the video the quicker the values will travel from “0 – 100”.
Now we want to turn the bypass ON as we don’t want this effect on until we say so.( – any time you require.)
[NOTE: you can also type inside the field ON or OFF]
I have watched my video and know that when the video reaches 33% I want the blur actor to be turned ON. You will need to watch the video and find the point at which you need an effect/trigger/sound to be triggered. The movie player does not output time, only a percentage. This means you need to sit and watch the video and work out the percentage value.
Hopefully you can see clearly that the low number is 33 and the high number is 45 – this is the ‘Inside Range’!
Once wired up, like below, the actor will send a trigger to say when it has entered and then exited this range:
I have added the toggle actor to switch between On & Off and this then does what I needed.
Here are a few screen shots using the same principle but for other ‘events’…
