    Q: How Slow Down Overall Speed (Not Velocity or Life) of Emitters?
    ________________________________________________________

    Applications relevant to question:

    — PI-3 and Sony Vegas 6 (NLE)

    General sys specs:

    — Pentium D, 2 Gb. DDRAM2, XP Home SP2

    I need a more slow-motion look to the emitters I am creating, i.e. ocean waves, clouds, flying stars, etc. The default emitters tend often move too fast for my work.

    So to clarify: What I mean by “speed” is that for example waves need to look slow, natural, to dreamy and ethereal. Not strung out on a case of Red Bull 🙂

    Tweaking either life or velocity does change the speed, BUT it also naturally drastically alters the look of the emitter behavior. No-go. If weight + or -is a factor in some, well, so far tweaking those parameters hasn’t worked too well either.

    So…

    What I am having to do at this point is to knock down the time-line speed of the PI .png files in Vegas to the maximum slow-down Vegas can allow per media event (file in track): 0.25 or quarter speed.

    But it’s not the optimal solution for various reasons.

    Now, my guess is that due to the variety of emitters (area, point, super, etc.) the very nature of the emitter(s) alone or in teamwork may limit any major “slo-mo” speed tweaks. Or not. Dunno. That’s why I’m here to ask for some…

    … wisdom and advice on this subject. Thanks.

    PS: I usually work on creating emitters in and as a project before saving them individually as a library. Reason: one can use Ctrl Z to undo changes (r-clicking for “Properties” for an emitter doesn’t, as far as my experience with PI-3).

    In many cases, the Over Life graphs are what’s driving the action, so the shorter the particle’s Life, the quicker the animation will be. If you increase the Life to slow them down, you usually have to deal with more particles on screen so you may have to lower the Number graph.

    Thanks, Elvis.

    I’ll go and try using those two parameters in tandem. From what I understand from your suggestion, one has to balance upping one and lowering the other in order to get the right middle ground (desired overall output speed).

    (Your name sounds familiar… Haven’t I seen it in emitter libraries? If so, hey, I’m dealing with high-tech celebrity here 🙂

    When I want slow mo type particles – as long as the particle shapes are not animated – I just se the project to have a fast frame rate, and then scale each animated property.

    So for example, if I set it to 240 FPS (which is 8×30 FPS) then I go into each parameter that’s animated, and use the scale function to scale them by 800%. IT can take a whole for more complex emitters but it usually works.

    Thanks, that sounds like another good option and I will experiment with that one too. The more options, the better 🙂
