Thanks, crocdoc.
Obviously, I'm not familiar enough with BCC Optical Flow.
I had a lean toward AE...leaning further.

Oh, my apologies, I wasn't aware that BCC also had a filter called Optical Flow. I had assumed there was just the Apple one.

I can't comment on how it compares to Twixtor.

For what it's worth, if you don't already own AE it's a brilliant program for a thousand different reasons aside from slow motion.

It depends how slow you want the motion to be and what the target playback rate will be.

For example: 60p can be slowed down to 40% of its original speed to match a native 24p project. No interpolation (i.e. new frames created) is necessary and can easily be done in Vegas simply by opening the properties of an event and changing the playback rate from 1 to 0.4.

If you want to go slower than that, then Twixtor is a great product. Twixtor Pro and AE provide even more control over the quality of the retimed footage by using masks, etc.

Thanks, Jive. I'm looking for dramatic slomo in the 5-20% range.

I have both AE and Vegas and prefer to edit in Vegas, but not sure what I'm losing by using Twixtor in Vegas vs AE. Costing more render time, and possibly resolution, by rendering back and forth between AE and Vegas.

I'd love to get Twixtor Pro, but Twixtor "Regular" fits in the current budget...although an upgrade to Pro is only available with AE, for now.

"I have both AE and Vegas and prefer to edit in Vegas"
That's to be expected, as Vegas is an editing program, whereas AE is designed to be a compositing/motion graphics program, rather than NLE. It's clumsy as an editor, but as a compositor it is outstanding.

If you were looking at Twixtor Pro, I'd absolutely recommend using it in AE because you'll be able to use the splines and rotoscoping tools within AE to really tweak your project. I haven't tried the Twixtor 'regular flavour' demo for Vegas, but have tried the Twixtor Pro demo for AE and if I were to get one of the two, I'd opt for the latter in an instant.

If you're not going to go in for the tweaking available in the 'pro' version, have you tried AE's inbuilt time-mapping features? I think the filter is called 'timewarp'.

What you may want to do is download a demo for Twixtor 'regular' and try it out with a sample of the sort of footage for which you intend to use it, for the footage will make all of the difference in the world in determining which program will suit your needs. If you haven't tried any slow-mo programs, you may be wondering why I keep referring to the availability of splines and rotoscoping as being important. If your footage is of a single person/object against a plain background (a skateboarder getting air against a clear blue sky, for example), even the most basic of time-mapping programs should be able to do a decent job. If your footage is of a group of people or objects against a busy background, you'll need to instruct the time-mapping program which bits are foreground and meant to be moving in slow motion and which bits are stationary background and to do that you'll need to rotoscope bits and define edges with splines and points. Otherwise the time-mapping program will confuse foreground with background and you'll get odd distortions and morphing.

"I'm looking for dramatic slomo in the 5-20% range.While certainly not as good as Twixtor or johnmeyer's AviSynth methods, just shooting in 60p is quite amazing. The following was shot in 60p an placed on the Vegas timeline with a 10% Velocity envelope.

Thanks, all.

After listening to my Video2Brain, 14-hour AE indoctrination training with Todd Kopriva and Angie Taylor, I have a better feel and comfortability with AE. I am definitely excited about weaving AE into my workflow. Trying to work out the details as I become more familiar with AE. Hence, I am here to drain video brains.

I have read that many do not consider AE's Timewarp to be as adept as Twixtor, but I haven't yet actually tested it. I've tested demo versions of Twixtor both in AE and Vegas 11 and liking both, but matching color, etc. between Vegas and AE might be more than I can handle presently...still learning though. I'll have to check out johnmeyer's program, as well.

This is a (very) rough cut of a project using Twixtor for Vegas to check out workflow and speed ramping, etc. It was shot in 1080 60p with a Sony CX560V and slowed to 8% in spots.

Nice shot Jerry. I’ve tried to get some decent in flight bird shots from a tripod. it is very very difficult. On a rig is slightly easier with a wide lens but still not easy.


If I take a 50 fps clip with a velocity envelope to run at .5 or half speed in a 50 fps project render, what is Vegas doing in the render?
Doubling the images or creating a new frame?

So the velocity = 25 frame in a 50 frame render. It appears to be smoother compared to a 25 fps render.

Thanks, Jerry. I've stickied the sticky.
