This is a great DCP naming tool that takes all the strain of getting the naming correct:

Glad you like it. It’s obviously less than perfect since it’s only possible to track the left and right motion rather than anything on a diagonal*, but for many purposes that might be enough.
Personally I always favour just a small amount of motion blur rather than huge quantities.
In real life the amount of blur depends on the choice of shutter angle so a certain amount of “stutteriness” is not unacceptable. Have a look at Ridley Scott’s Gladiator for an example of an extreme shutter angle that aims to eliminate as much motion blur as possible. It’s very striking.
* For that one would need vector information (not achievable with Motion alone) and that starts to slow things down again so it rather defeats the point.

Does the Grid Warp tool not work for this? You can easily set it up to stretch just the top half of the frame.

So you got me thinking if there was a way to add fake motion blur (in a way that wouldn’t incur the hefty overhead of the real motion blur option), and I have quickly put together this version:

The Motion Blur amount can be adjusted to taste and can of course be keyframed if required.
Hope that helps.

Glad I could help. This is an extremely helpful trick that has countless possible uses. I keep finding new ones all the time.

[Frederik Meuris] “1. (How) can I loop a Numbers generator so it starts over at 0 after reaching 9?”
a) Disable the Animate parameter in the Numbers Generator and instead add a Ramp behavior to the Value, starting at zero and ending at 9 (and zero out all the other values);
b) Clone the result;
c) In the Timing pane of the Clone set the speed you want for the numbers animation and set the End Condition to loop.You now have a 0-9 loop that you can adjust to taste.
[Frederik Meuris] “2. (How) can I have these generators start at different numbers? I want a screen full of generators going from 0 to 9 over and over again, but I don’t want all of them to reach the same number at the same time.”
Make a Replicator of the Clone and in the Replicator controls enable Random Start frames. Set up as many columns and rows as you need to fill the screen to taste. Use either Arrangement/Tile Fill for a uniform layout or Arrangement/Random Fill for a more organic look.
Here’s an example of this method:

This list of feature requests in respect of F16 show how specific and precise the requirements of professional Fusion users can be, and with good reason:

UI design is ridiculously important for detailed VFX work and any wasted screen real estate can be a big problem.

[Beth Block] “Where’s the multilayer merge node?”

My thinking with this expression:
iif(time>n, time-n, time)… was that for any time value below n the Time Stretcher would give you the same frames as the source, but that once it hit n it would give you the source time minus n.
But I made a mistake in my counting which means I’m out by a frame and it should have been this:
iif(time>n-1, time-n, time)So if you merge that over the top of the original source you should get the same two frames on frame zero; frame one plus frame zero on frame one; and so on for each instance of the Time Stretcher/Merge operation.
In other words this:
iif(time>4, time-5, time)… would give you the same frames as the original up until frame frame 5 (counting from zero), and on frame 5 itself would give you the original starting frame of the clip.
In other words, until the value of N is exceeded the result of the Time Stretcher will look identical to the source, but thereafter it will look like the source time minus n.
From what I have been able to understand that’s what you were trying to achieve. So on frame 6 for example, you would be seeing frames you would be seeing frame 1 plus frames 1 to 5 inclusive.
Here’s a sample composition that shows that in practice (with 8 instances of the Time Stretcher.)
I’m afraid I still can’t quite envisage the effect you are going for with your Merge operation so it may be that you want to effectively disable the output of the TimeStretcher operation until you get to the frame where you want the offset to kick in, in which case you’d need an expression on each Merge operation to get that to happen.
Does any of that start to make sense or help at all?
