Best Slow Motion Method

TimTyler wrote on 5/10/2005, 3:26 PM

What combination of shooting FPS and Vegas v6 project settings should I use to achieve a quality slow motion effect?

I've run some tests (DVX100a) using 24PA and 30P frame rates and then dropping them in either a 24P or 29.97 Vegas project, and the results were less than acceptable when adding a 50% velocity envelope. I rendered each test to a 29.97 AVI.

Is there a magic formula for slo-mo?

Don't know if it's 'magic' or not but shoot at the highest fps you can and use a faster shutter speed. In other words get as much temporal data as possible and avoid motion blur that will not belong in your slowed down footage.

Are there thrird party plugins that do a better job of making slow motion then the Vegas velocity envelope?

No plugins that I know of. There is a third-party slow-mo app called Motionperfect from Dynapel. It uses motion estimation to create the intermediate frames rather than adjacent frame blending. I think there are other high-end applications that do the same thing.

vegas is teh best slow mo app on tehket in this range of editors..

simply bacause its velocity and stretch tools are frame accurate off teh timeline..

on top of that, u can either blend (interlaced) or interpolate (progressive) these frames..... THEN.. u can supersample.. bascailly running multiple passes on the footage..
if uve heard of audio "oversampling" this is teh video equivalent..

Somebody ever tried the Dynapel app?
How's it?

See my earlier post:

There is another level of professional tools for this.

Better results thanks to actual creation of intermediate frames, using a fair amount of intelligence.

Twixtor is one of the top two in this category, and it's at least not super-expensive, but it needs to work in either AE or Combustion to handle frame rate conversion.

See Twixtor and look at the examples and tutorials there too.

There was an old post about this in these very forums:

Scroll down, and johnmeyer's second to last post has some settings that I've used to get very good results.

I don't suppose you have any footage of high speed action that's been slowed using Twixtor do you? Preferably before and after examples?
