Particle Illusion Speed
on Mar 4, 2015 at 11:49:38 pm

Whatever emitter I use, let's say fire with smoke, it's too fast, I mean when I import it to Vegas, I have to speed it down from 100% to 30% otherwise fire and smoke move too fast.
Is there a way to control speed in PI?
There's speed control in PI but it's not about how fast emitters look.
Thanks ;)

The sliders are there to slow it down as you needed, you need to take
your time to find out which slider changes its velocity, there are
tons there.

Where are those sliders?

[Joao Souza] "Where are those sliders?"
Joao, there this a "warehouse-full" of ways to achieve this. I have the pI Plug and the standalone s/w. It is a majoraly powerful FX - and no mistake. It has taken me the best part of 6 years to grasp/understand just what I can do with it.

OK, 2 questions:

1] What are you using standalone or the Plugin into Vegas directly?

2] What Smoke and Fire version are you using?

1- Stand alone.

2- It doesn't matter, I said any emitter I use.

My question is simple, how to make an emitter plays slower?
If smoke is fast, just slows it down.
I don't want fire burning at a 100 miles per hour LOL

[Joao Souza] "Whatever emitter I use, let's say fire with smoke, it's too fast, I mean when I import it to Vegas, I have to speed it down from 100% to 30% otherwise fire and smoke move too fast."
I understand then you are using the pI standalone, and then render and import to Vegas. In which case there are no "sliders" in pI standalone. To make fine adjustments we use the Graph adjuster for each of the variables. This took me sometime to grasp. So here you have Speed, Life, Weight and so on. And these can be adjusted for each of the Parameters that make up say Smoke and fire.

However . . . .

Like videoing for good slomo, we need to Video/capture at a higher framerate than we will setup our NLE. And here that means creating MORE frames per second than is needed at the lower framerate.

I've just rendered out of Standalone pI Smoke and Fire at double my 25fps, I set my pI render at 50fps and once back into VP13 I added a Velocity Envelop to 50% and the Smoke and Fire looks smooth and useful.

I set my pI Project to DOUBLE fps, 50fps. And now I'm trying 100FPS!

Ok I know that stuff but still you didn't say how I make emitters play slowly, how do I change their speed?
Is there a hidden speed button?
Or the only way is changing their speed in vegas?

[Joao Souza] "Is there a hidden speed button?"
As you say, you "know" that stuff, then what is your question? No hidden button! LOL! - As to adjusting back in Vegas, all I did was to take a DOUBLE and now QUADRUPLE Frame render and place into Vegas. Seems Logical to me - no? Seriously - to make better slowed-down output from pI I put up the frame-rate. Yes, we can adjust speed and weight and Life - over time of the Particle - but really, frame rates gives you a chance to "fill-in" the gaps of the frames so that back in Vegas you/I can get a better slomo. The adjustments you get in pI are great for the finer adjustments, solid slomo . . .? Actually I SHOULD be asking how MUCH slower do you want?

I've just rendered out at 100fps and it looks fantastic! I'm preparing an upload to COW now.

I already said it, in Vegas I apply that velocity filter then slow it down from 100 to 30, let's say about 70% slower.

We're moving forward . . .

Slowed Particle Smoke and Fire

Here's what has been said by heavy users of pI. Note what the designer of pI Alan Lorence, says on Speed and Life, on adjusting the Speed ramps etc . . BUT, finally Reber Clark's advice on FPS - yeah?

OK, https://forums.creativecow.net/readpost/23/855594

Do read ALL of this and you'll find that what I said holds.

Pay special attention to Reber Clark's working methods . . Sound familiar?
"This what I did in Vegas and it worked great. I was trying to slow down the "spread effect" in the WAVES2 emitter in the "water" collection:

1. Determine the length of the clip to be used in Vegas.
2. Execute and render your effect in PI at that length but set frame rate to 120fps (or higher) in "Preferences" in PI.
3. Put the render from PI on the Vegas timeline (it will be shorter) and CTRL-stretch (time stretch, not repeat) the render to the original frame length.
4. A smooth reduction in the effect speed is produced, approx 4x slower than the original."

Here's another one with:
1] High quality Motion Blur

2] Non Intensive ALPHA

Slomo Smoke and Fire

Any comments, Joao?

Well, I'm not talking about quality but about speed.
With good or bad quality, I wanna change emitters speed in PI and not in Vegas.

Did you read the information from the designer of Particle Illusion?

Sometimes I did that too(CTRL-stretch) but I never changed frame rate, still I'm changing speed in Vegas and not in PI.

Do read what the designer of pI says and the way forward with framerate.

I bet you do NOT get the quality by just applying the Velicty or speed ramps in Vegas.

Cheers

Grazie,

I never thought of that approach - it is an excellent suggestion, and something I will use for my PI renders..

I struggled to get a bunch of clouds slowed down with that smooth action for a flying-carpet sequence, and I wish I had thought of this.

Thanks.

STBO.
