Frame rate doubling [Twixtor]/[ReTimer]/[Continuum Optical Flow] in Vegas ???

[John Rofrano]

Vegas does this automatically with no intervention from you. By default it will resample media that does not match the project frame rate and create the in-between frames. No need to switch to Adobe for this. In fact, Adobe could learn a few things from Sony about letting the computer do what it does best and not requiring video editors to be rocket scientists and worry about these things. 😉

No kidding? Thank you for the info, I never would have guessed.

So when one slows down a clip (expands it while holding ctrl) it’s already composing frames to insert at render time? Is there a menu somewhere we can access to control this, crank it up a bit?

I just finished a project at 23.976 FPS. If I wanted to double this to 46 FPS and make sure Vegas does motion approximation, once for every frame, is there a special menu I need to navigate through or trick of some sort?

When I right-click the media clips for the project in the Project Media window and go to properties, I notice the Frame Rate is always greyed out at “23.976”. It’s ok to just leave it that way?

My goodness, I just went to Project Properties and right there it seems you can switch to “59.940 (Double NTSC)”!

Very excited to find out what happens when I render with that option checked!

As you see you don’t have to switch…lol
Also nothing is wrong in having a version of after effects
running as a comrade with sony vegas…having these two in
ones workflow is pure heaven.
Also twixtor is the superior king over all other plugins in
its class, including after effects built in features..

I notice Vegas inserts a kind of blurring effect there rather than drawing/guessing real in-between frames. And you can pick from 6 quite passable blurring styles.

This works fine, though it is a bit obnoxious when you freeze-frame and see how blurry what you’re really watching actually is. I’d rather if the video had a succession of clear unblurry frames, as the difference is noticeable. Blurring just doesn’t seem as polished as the real thing.

So Twixtor can draw the real frames, not just blurs?

And you mention After Effects. I have no experience with After Effects, but tell me this –> Can I import my Vegas .veg project file into After effects and keep all my timestamps/speedups/slowdowns and so forth?

If I buy After Effects AND Twixtor [my wallet is saddened by this prospect 🙁 … ] can I then run my final Vegas render (.mp4) through AE/Twixtor and obtain a genuine non-blurred, motion-approximated 60 FPS video file from the original 29 or whatever FPS file?

It’s just that I saw someone else seriously improve their animated project by doubling the frame rate very professionally, and looking at the music video I can see there’s no blurring in-between frames at all. Crisp, professional work.

The animated clips the guy used as the source were naturally choppy, but the way Twixtor cleaned it up was just unbelievable. He also said the render took 3 seconds per frame at 60 FPS with the latest hardware 😀

Right-click on the event and select Properties. On the Video Event tab you can select from Smart Resample, Force Resample, & Disable Resample.

There is also Video Supersampling which will smooth out the way that Vegas calculates the intermediate frames. To access this you first must expose the Master Video Bus track (Ctrl+Shift+B). Then right-click and choose Insert/Remove Envelope | Video Supersampling. This will insert a supersampling envelope. You can raise that envelope to increase the rate of supersampling which determines how accurate Vegas is when it creates the blended frames. This is how you crank it up a bit!

Thank you for your help and patience! I’ve enjoyed fiddling around with encoder options, blurring styles, velocity envelopes and supersampling. Making test render clips and critiquing the differences. Glad to finally see first hand some of the pains and pleasures video authors have to go through.

The fuzziness of supersampling lacks professional level polish that I assume one can get by running their final encode through Twixtor and Adobe AE, but it gets the job done for now.

Nevertheless, I’m still itching to find a way in Vegas to insert non-blurry/ghosted motion approximated frames and save my wallet from getting sucked into the Adobe AE vortex 😛

Hi ,
i am a newbie and i was facing the same problem. my project is pal dv wide screen (25fps). i have two clips , one is 25 fps and the other is 20 fps . if i import both the clips in the current timeline , vegas will automatically change the frame rat. but if i have to use super video sampling only on the 20fps clip for better estimation of frames . can i do that ? if yes then what would be the steps.

Thanks,
Furqan
