animating a title?

If the red dot is not on, then that property will not be recorded in the scene. If the red dot is on, then when recording starts it will create a “take” (a recording) that includes that property value.

So disarming the property first changes the default value for that property. So I start it at 0. I find that less confusing. If you then arm the property (red dot on) and change the property value, you do not change the default - you are setting the property to the initial value it will use for the recording. If you then start the recording, it will record that value for the property from the beginning. I wanted a recording of the same 100% value for the full recording because we are going to use a blend to adjust from the default value (0) to the recorded value (100).

If you record without changing the value like you described and then later while recording adjust it to 100% then if you play back the recording, it will start at 0 and then later go up to 100%, time synced with when you made the changes. Remember CH is a performance based approach. It remembers each change you make and when you make it.

So you need to set default to 0, arm the property, set it to 100, then start recording. You will then have a recording of the property at 100%. Then you have to use the blend to smoothly transition from the default to the recorded value (which will go from 0 to the recorded value of 100).

For example, instead you could by hand slowly drag the scale value up while recording, but I find it hard to get it perfect. It comes out jerky for me. So to get a smooth transition I find blends work better.

Normally blends are used just at the start or end, to smooth the transition between two takes that don’t exactly line up. I am using this by going to an extreme and doing a long blend from the start of the scale to the end of the scale.

The video link I shared uses short blends at the start and end of the opacity recording I did. It shows it fade in and fade out with shorts blends at the start and end. It then goes on to show full scaling blends towards the end. It is a screen recording of every step I took, skipping nothing. So that might be worth viewing and following along on.

You just have to remember there are no keyframes. It records the current value of armed properties each time interval. Blends allow you to quasi fake key framing, which gives you smooth transitions. That video has a series starting from a photo of a toy wookie, each episode building on the previous one. So if you are new, it may be worth starting from the beginning to learn the basics. That might help the penny drop. Once you “get it”, things go much faster.

Oh, here is a screen recording that shows some different things - it eventually shows blending etc. Fast forwarding might be useful! ;-)

CH is a “performance based recording” tool, not a key frame approach. E.g. you turn on the web cam and it does real-time recording of head positions etc. (Or you grab a draggable hand and just move it around as appropriate.)

Blends can be used to *fake* keyframing. You basically make a recording of the end value, but the recording is actually a jump to a new value.

So, the exact sequence is:

• Have the red dot disabled for everything.
• Set Scale to 0%.
• Turn red dot on for Scale property.
• Set Scale to 100% (or whatever).
• Press CTRL-R to start recording.
• Wait a second or two.
• Press CTRL-R to stop recording.
• Find the blue bar in the timeline.
• Adjust the right edge of the blue bar to extend it out as long as required (its fine to go too far)
• Grab the little square in the top left corner of the blue bar, and drag over to where the scale up should stop.
• Right click on the bar to change to adjust the blend mode (easing) if desired.

To make a recording, you press CTRL-R or press the record button to start and then later stop recording. You can grab the scale value and fiddle it during a recording and it will remember exactly when you make the changes. We are not doing that - we are setting the initial value then not changing it during the recording (so it feels a bit weird).  For most properties, the last value in the underlying recording will be extended when you grab the right edge of a “take” and extend it. It basically fills the values in. (This does not work for all properties, but does work for most.) What that means is you don’t have to create a recording *exactly* the right length - you just need a recording to start from then trim the edges as desired (which is easier to control).

If you want a simpler to understand approach, you can record for the full duration of the transition then trim it shorter. I just have got so used to start record / stop record and extend that it has become second habit for me. There is also a “record 1/2 frame” in the menus, but I find I need to zoom in before I can grab the edge of the recording. So I just manually hit record, wait a second or two, then stop the recording, and extend the take. If there was a ”record 1 second” shortcut that would be convenient - it would save me one key press. ;-)

Oh! Maybe that is what Dan is referring to - there is a new capability I have not used yet. You set the Work Area settings and the recording will automatically stop at the end of the work area... I have not tried that before.

Oh, note you can record changes in X and Y position as well, if you want to to fly up during scaling as well.

Create the file in Illustrator, import it into CH which will turn it into a puppet, then use the Transform behavior Scale property to adjust its size (you can delete all the other behaviors on the puppet if you want to).

Use a blend for the scale. That is,

1. Put the puppet in a scene and set the Scale property of the puppet to the initial size. (Do NOT arm the property - we are setting the default value for the puppet in the scene.)
2. Arm the property (click the red dot) and adjust the scale to the final size you want.
3. Record that for a few seconds then stop the recording.
4. Grab the right edge of the recording and drag it out past the end of the scene - it will use the last recording value for the whole take now.
5. Adjust the left edge of the take (the blue rectangle in the timeline)  for where you want the scaling to start.
6. Create a blend by grabbing the little square at the top left cornder inside the blue recording of the take and drag it over to the right. You should see a diagonal line now growing from left to right (instead of a solid blue rectangle). This is a blend, going from the old value (the puppet default) to the new value (the final scale factor you want.)
7. Finally, right click on the take and adjust the “ease” value - the default is to ease in and out which slows near the ends of the take - if you want it linear, turn off the ease.
