  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

the end of high speed shooting

didn't believe it when i heard about it.. but finally tried twixtor out for myself... fully impressed..

why waste space, and use expensive high speed cameras when this software does an excellent job...
 
I've used a phantom many times. I've seen really good looking twixter footage..obviously I've seen the bad..

but when a 2000/day phantom rental isn't going to fit in the budget.. software will.. and it will only get better
 
Twixtor is a total failure when it comes to water or other fluids... What I use high speed for the most.

and the more complicated the shot, the more you'll get the strobing and artifacts. in the end it's software artificially creating the extra frames. no matter how good the software gets, the more complicated the shot, the more important it will be to actually capture all frames. I think high speed shooting is only gonna get cheaper, easier, and more insane. the Flex has put more units out on the market than the hd gold ever did, and the next iteration will be even easier, and at a higher quality image/resolution. it would be more interesting to see high speed footage shot, and than twixtored to really push it even further.
 
To say that Twixtor will be the end of high speed shooting is just ridiculous. Twixtor=cheese ball!
 
Twixtor is a great tool with heavy limitations. It doesn't substitute high speed shooting, obviously, but can help in certain scenarios, like the example bellow. Notice the "twixtorized" shots last less of a second- because the margin to get artifacts in the footage is very high- If this was shot during raining, for example, you would have motion artifacts everywhere. However, it did work here, and it looks shot in high speed. Which means impressive slow motion at a very affordable budget- it worked for this!

I disagree and prefer to capture slow motion in camera as Twixtor still has difficulty in detailed scenes. Think hair bouncing while running on the beach.

However, there's a totally opposite way to look at this. By shooting at 120-300fps in high speed and high resolution you can do a heck of a lot more with Twixtor.

Twixtor likes "information". The more you give it, the better it behaves.
 
wasn't being serious when i said end of high speed shooting.. but i just discovered this software and i think its pretty cool. whats the other options for 1000fps besides renting a specialty camera?

Easy: Shoot 120FPS on Epic and ramping up or down in post. For action, burst sports this is going to be my FR
 
The only thing I find it really useful for is automatic morphing. I'll hand paint key frames and then let kronos drive the morph. Must easier than spline warps and with some roto cleanup can just use the parts that aren't unusabley glitchy. Also good for extending shots where no big actions are happening like an actor holding a product. Just bounce back and forth between a few random frames and it usually looks pretty natural with proper easing curves. Now that I think about it, I almost never actually use Khronos etc for straight up speed ramps haha.
 
I expressed an interest in that TS3cine product at NAB, but the dude showing it was a total DOUCHEBAG. Not to mention the camera left a bad taste in my mouth. If I "Had to" I'd rent the Phantom, the olympus high speed system or the Y5HDiablo system. Epic at 300 is pretty damn slow for most of the slow mo I need -

Poll: better for 1,200 fps output via Twixtor:

300 fps @ 2K
120 fps @ 5K

Or anything in between!

Edit: With background detail overlapped by slow-moving foreground subjects.

Personally, I think MVFlowFPS gives better results. But re-timing in software works only on solid and large objects. The moment you introduce particles and detail, they fall apart.
 
Twixtor and the like are very neat, and can give really good results. Some shots take more finesse than others. But you just can't beat the real deal...
 
The expense of renting a Phantom or similar can often be about the same, or less, than the cost in post of making it look as good... assuming it's even possible with the shot at hand. There's also the option of faking it with CG, which works especially well these days for fluids and atmospheric effects like fog or smoke. Interpolated approaches like Twixtor can do alright, but they do struggle with fluids more than anything.

For Deinnis' question above: 1200fps output via Twixtor, that depends heavily on the subject matter. But I would lean toward 300fps @ 2K for that one, the more frame info the better, more frames = less interpolation. 5K @ 120 can work if you need the extra resolution. Especially if you're not doing fluids. There may be some advantages here for more rigid body motion.
 
Twixtor works well if you shoot against even background like sky, wall etc. But it doesn't work well in other situations. This of course depends how much you are going to slow down.

It workder well because of the objects moving direction. I've made test with 1080p/60p shooting motorcycles going 150km/h next to me about 10 meters away and the material was useless because there's no enough frames for twixtor to work with. It wasn't even enough on the scene where a driver drove 100km/h and came behind the corner of the building. The wall merged to the motorcyclers back and looked like a liquid. When the driver was around 1-2 meters away from the corner the problem went away. These all shots would have needed at least 120fps.

I was slowing sown to 5-10%.
