Anyone use Twixtor?

So I recently found out about this program that is supposed to have superior frame blending time warping abilities to anything that any user should be able to create.. just wondering if anyone has tried it and can vouch for it?

I do a ton of sports shooting and action shooting and always wish my 7D could shoot higher than 60 FPS at many times.

Is this product worth it? Also, what's the render-only version mean? I don't think I will be able to afford the full thing >.< and I don't even know what the difference between Twixtor or Twixtor Pro is, but another increase in pricing there -_-
 
Yes, just finished a workflow analysis for 5D -> 30p to 24p that looks very impressive. Twixtor works best when you're slowing things down (IMHO), however if you shoot at a fairly high shutter, over 1/200s I suspect it might work well. It works pretty much as advertised.

With regard to the 30p to 24p nothing could be simpler using AfterEffects. The one thing you need to be prepared for is very long render times. A 3 minute clip on a 2.5Ghz Quad system took about 45 minutes to render out!

Cheers,
Dennis.

Thanks for the response Dennis!

What version of Twixtor do you use? Do you have any idea what render-only version means? If I can get it for ~$70 I will definitely purchase it now.

Also, going from 30 to 24p, can't you also use CinemaTools (free app that comes with FCS) pretty easily or is there some difference I'm missing?
 
If you're in a FCS environment, check out the Optical Flow feature in Motion for great slow-mo.

Twixtor is great, but you need more than the render-only version. The pro version allows you to dictate complicated moves by using mattes. They have some example videos that show the difference.

Thanks a ton, Tim! I wasn't aware of the possibilities using Motion since I'm not familiar with the program. Perhaps it's time to get acquainted :)
 
Can Anyone Verify that they've tried this and it works to sharpen up the image?

---- Does anyone know if a high (fast) shutter speed (1/200 +) makes the image sharper? I usually just use 1/50

However, Twixtor is awesome btw! I'm going to buy a copy of the standard for sure - it did an amazing job on a project im working on.

If you're talking about slowing down the footage, and therefore creating frames to fill in between existing frames, as Twixtor does, then you want to think about the shutter speed carefully.

A faster speed means less motion blur, which is a kind of "sharper" image, yes. But, you want to have some motion blur, or the images in motion look stuttery.

If you try and aim for a 180 degree shutter, then it's half the time open, half the time shut. This translates to something along the lines of (someone will correct me if I'm wrong, I'm sure)...

24fps / 1/48th sec. shutter (180 degrees / normal film speed) TO 48fps (slowed to half speed) needs a 1/96th sec. shutter when you shoot it. Something close like 1/100th is fine.

24fps / 1/48th sec. shutter (180 degrees / normal film speed) TO 96fps (slowed to 1/4 speed) needs a 1/192 second shutter when you shoot it.

These would be treated like special effects shots that require more light in order to get those high shutter speeds.

Shooting 60 fps in the first place, and then slowing to 24fps playback gets you there much better. The same guideline should apply: 180 degree shutter means 60fps / 1/120th second shutter.

Mileage may vary.
 
Thank you for that.

Has anyone done a video test showing the difference between frames and shutter speeds? --- Google Searched And Found It ---- http://www.brando5.com/2010/07/07/s...frame-rate-comparison-tests-canon-5d-mark-ii/

Looks like 1/100 was the best balance between smooth movement and sharpness, except for 1/200 during running scenes.

Interesting - On a related Twixtor Note -- realizing this has to be used specificially on a clip - not as easy as I thought of just dragging on to all my clips with speed changes and having it automatically improve the speed change!!

Final Cut Pro Needs a sweet implementation of this..... !!!
