Ah ok I looked at the file and that’s great, problem solved!

Thanks and much appreciated you’ve saved me on a deadline 🙂

Thanks for the answer!

I haven’t yet used espresso, would you have any idea how I’d go about this?

Thanks Adam!

Hi Kevin,

I think I understand what you mean, I assume the base value your reffering to is the stopping point of the object? (last keyframe).

Is there anyway you could be kind enough to mock me up a basic example to take a look at in AE?

Thanks for your help!

Dan.

Hi Steven,

I wanted to figure out how to do it manually because I think it’s good to know, feel like I’m cheating sometimes constantly using expressions!

[Daniel De silva]

Hi Kevin,

The main expression I use is as follows:

// Inertial Bounce (moves settle into place after bouncing around a little)
n = 0;
if (numKeys > 0){
n = nearestKey(time).index;
if (key(n).time > time){
n–;
}
}
if (n == 0){
t = 0;
}else{
t = time – key(n).time;
}

if (n > 0){
v = velocityAtTime(key(n).time – thisComp.frameDuration/10);
amp = .05;
freq = 4.0;
decay = 2.0;
value + v*amp*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t);
}else{
value;
}

Any idea what I could do keyframe wise to achieve something similar? doesnt have to be exactly like the above, just would like to know how to keyframe one in general!

thanks

Hi Adam,

Thanks for your input! It deffinately worked better but seems to have lost some of its finesse. It looks pretty clumpy. What would you do to get a nice effect as you can kind of see what im going for?

Also it emits in different directions now but not really all around it, would there be a way for it to emit 360 degrees around the sphere except not shoot out from the front (where the face is).

Finally, the transparency works to make it more opaque but I dont like the way the particles show through each other when they overlap, is there a way to turn up the transparency on like a laye or something instead?

Sorry for all the questions and thanks for any help in advance! Really appreciate it! I’ve attached two videos following your advice (one cone, and one pyramid) so far.

Which codec would be best for loseless quality? thanks! yeah i figured the nesting and resizing down to 720p, but when i render it to h.264 the colour quality is very washed out, when i render it in quicktime with a h.264 codec the colour image is good? Is what you described above the best way around this?

[Daniel De silva]

ah ok great thanks. I tried re-sizing the comp to 720p which worked fine, but when i want to export it as a mp4 (presuming h.264 is best for web) it appears washed out :/ any advice?

Hi Dave,

I’m rendering out to H.264 through AE. I’ve managed to fix the banding problem! Most of it was due to the initial image.

I have another question and since you seem to know what you’re talkingabout thought i’d post it to you!

How do I transcode a 1080p video to a 720p video?

Thanks,

Dan.

I’ve tried adding noise but it only reduces it slightly, (.8 noise amount). I don’t want to crank it up to far incase it begins to ruin the image.
