Twixtor Pro Tutorial - How to use Track Points in Twixtor Pro (720p)

[bakushkin2010]

Thank you!!!

[crawn]

how come you only use 2 frames, would it have been different if u want to use 3 frames? and is there a way to calculate what speed i have to use?

For example, i want a 25 frames long sequense to last 3 seconds instead, but my project is in 60fps. So 3sec is 180 frames and if u duplicate my 25 frames 7 times i get 175 frames, so what will happen to the last 5 frames? and how do i calculate what speed i need to use on twixtor

Thanks for the tutorial =)

@crawn

Of course it would also work when you use 3 frames instead of 2, but because at such a slow motion (less than 1%) and such a fast shutter, you will get serious blending problems and the result will look really bad.

Your calculations are right. Concerning the remaining 5 frames, you could also duplicate the 25 frames 8 times and in the end cut off the surplus part which you don't need in the final result.

[lenlenman]

after you applied twixtor to your video, you rendered it to show us. But after that when you went into adding tracking points, i noticed that your video was not rendered. Would it be best to render once we have gotten all of our tracking points in and when all the settings are how we want them? Or would it make the process go smoother/faster if we render after applying twixtor to my video and then again when everything is complete?

[DreamaginaryPictures]

@lenlenman

As far as I know, rendering before adding track points won't give you any advantages, because as soon as you add track points after rendering, any previous rendering is abolished and you have to render it again anyway (at least in Premiere Pro and After Effects). Moreover, when adding track points, you are working with the original (not-twixtored) footage to see each single frame to allocate each track point to its certain locations.

how much fps is 50i ?

[MrHDFilms]

@Haxuu 50 fps

[DreamaginaryPictures]

@Haxuu

50i means 50 half frames (the i stands for interlaced). So actually, 50i means only 25 full frames, but it is not comparable to 25p...

[Haxuu]

@DreamaginaryPictures It cant be that less?! i can still make ''decent'' twixtor out of it..

[DreamaginaryPictures]

@Haxuu

When a camera shoots in 50i, this means that the camera scans the scene with 50fps but only alternately captures the odd OR the even lines at a time. In contrary, progressive mode (as in 25p or 50p) means, that the camera captures complete pictures, i.e. 1080 lines in 1080p. So when you shoot some kind of movement in 50i, you capture it with 50fps, but each single frame will only contain the odd OR the even lines, which lessens the quality. But of course, Twixtor will work :)

[Haxuu]

@DreamaginaryPictures daamn.. why does the american version of this camera shoot in 60fps, and the european in 50i, its so stupid..

[elboysfabrajr06]

great tutorial, best twixtor tutorial i ever seen!

[greendaydiaz]

Great tutorial! The best on youtube. My question regarding the tracking points is: I have a person doing a back flip and i am getting warping. Do I motion track his whole body?

[DreamaginaryPictures]

@greendaydiaz

As far as I understand track points, their purpose is to support the separation of object of interest and background so that Twixtor "knows" where the boundaries are. In this regard, I'd first try tracking only the areas and body parts where inaccurate warping occurs.

[ilove2film]

@DreamaginaryPictures Thanks for the quick reply. I noticed that on your video you only had two frames to motion track, my footage is much longer so I'm going to try to minimize motion tracking as much as i can due to so many frames. Here is the video i worked on and I still have lots of work to do to smooth out the slow motion.

[greendaydiaz]

@DreamaginaryPictures One other thing. I noticed that you used 0,286 for speed. I couldn't tell if that was a period or a coma?

[solidbrownrecords]

I would like to see this tested with a hummingbird.

[JMEcalisse]

thanks for the video but when i render, it does big orange X in the screen :O help please!!!

[DreamaginaryPictures]

@JMEcalisse

You gotta get the full version...

[DreamaginaryPictures]

@Kodemann

Yes, sorry for the bad vocabulary...

[jontywhiter]

Do you happen to know if you can do this in Sony Vegas Pro 10? I have twixtor, and twixtor pro, but i cant seem to apply the track points. Thanks

[DreamaginaryPictures]

@jontywhiter

Some other guy once sent me a message because he had the same problem. I don't know or use Sony Vegas so unfortunately I can't help you here... Sorry :(

[jontywhiter]

@DreamaginaryPictures Ah ok no problem. Thanks anyway :)

[gbartot]

Thank you man, you made my day! I spent a week looking for a decent tutorial and finally I've found your one! great job!

[Mexichapi]

Is it better to work with 60 fps sequences and export to 30 fps (for Youtube upload) or work with 30 fps sequences and interpret imported videos as 30 fps? I keep loosing smooth motion when exporting at 30 fps.

[DreamaginaryPictures]

@Mexichapi

I would recommend the following workflow:

1. Shoot in 60 fps

2. Apply and render Twixtor in a 60 fps sequence

3. Import your rendered Twixtor sequence to a new 30 fps sequence and stretch your footage to 200% duration (50% speed) like a normal slow motion

4. Export in 30 fps

In this way you should be able to maintain a smooth motion AND you can slow down your footage even further (i.e. to 50%). Hope this helps.

[kasama9281262]

Cool!! Thank for Tutorial.

PS. How do you get 0.286 ?

[DreamaginaryPictures]

@kasama9281262

In the actual video I had to adjust the cut-scenes to the musical cues, and so I ended up with such a weird number :)

[plaguer]

Hey DreamaginaryPictures,

Very nice tutorial indeed, congrats !

I got a question. You adjust the speed to 0.286 so that means you slow the video by 350 X right? ((1 / 0.286) * 100) = 350) And you have used 2 frames so your video is 350 * 2 = 700 fps right?

[DreamaginaryPictures]

@plaguer

I think your calculation is right, but in the actual video I further slowed it to 50% (Twixtor sequence = 50 fps -> final sequence = 25 fps). So in the end the slow motion scenes are at 1400 fps, I think.

[sicksidemadness]

hurra hurra!

[ztanyas]

The best Twixtor tutorial! Thanks a lot :)

[DreamaginaryPictures]

@ztanyas

You´re welcome ! :)

[TheSmashDoctor]

YOU ARE MY HERO!!

[mrbungs]

Do you ever need to adjust the frame option, or just work with speed ? Does changing the frame drop down directly effect how many frames twixtor mimics?

[DreamaginaryPictures]

@mrbungs

So far, I only worked with speed. To be honest, I don't know (yet) what the frame option does...

[mrbungs]

@DreamaginaryPictures Thanks for the reply. I'm new to this and I have yet to see a tutorial that addresses the frame option so I am unsure of what it actually does as well.

[Nicco71088]

mmm...I see some ghost in my mind...can i tracking that?

[DreamaginaryPictures]

@Nicco71088

If you set the track points to the right layer it might work... ;)

[Nicco71088]

@DreamaginaryPictures LOL, you know how it work in Vegas pro 10? the interface is the same but i don't know where i can see the point in the video preview...maybe i must zoom more...i try! lol question and answere in only one message..good! i need really track my brain!

[Nicco71088]

@Nicco71088 No i try but i can't zoom the preview video! HELP! Where i can see the track point in Vegas ?

[DreamaginaryPictures]

@Nicco71088

I don't know Vegas, but if the interface is the same as in Premiere Pro you first have to set the layer for each track point to Main_BG (which is main background, your video) and then re-position the track points. By default the track points are outside of the frame (as indicated by the negative numbers).

[Nicco71088]

@DreamaginaryPictures Thank for your attention! i tried to set 300;300 for the first point, after i have set Main-BG for this point, but i don't see the red point in the video preview and also i can't move the point like do you do (with the movement of the mouse near the number of position).

[plaguer]

@Nicco71088

To see the dots, you have to add key point by clicking the clock-like button near positioning bar (left of the bar)

Just grab the numbers and move your cursor horizontaly

[halloosin8]

Thank you!



[Brianimanuel3]

Thanks!, now i know how to reduce the ghosting, even with a detailed background in twixtor! :D

[unprofoundcom]

I watched a lot of Twixtor tutorials trying to find someone covering the advanced features of Pro. Nicely done - thank you.

[addyduss]

awesome! Thanks a lot!

[gualix]

funkyyy yeeeah!



[madjimmy3]

aw man.. this is hard on AAE 5 . :(

[PredatorDeck]

now i`m extremely jealous, and pissed, i never am but for months i`m trying to get a slow mo like that. Thanks a trillion amazing vid

[DreamaginaryPictures]

@PredatorDeck

Thx, you're welcome! :)

[ForeverMind1]

There is this huge red "X" covering the screen in twixtor created stuff with "re:vision effects" on it....how do you take that out?

[DreamaginaryPictures]

@ForeverMind1

By gettin' the full version ;)

[AlexMercier550D]

@DreamaginaryPictures I am getting the same problem but i do have the full version ...



[ForeverMind1]

how are you duplicating the clips in your sequence?

[DreamaginaryPictures]

@ForeverMind1

just copy & paste

[Eltura]

An ok in AE I can do it, thnks :)

[Eltura]

Thanks a lot! Ok i Do the video... but, can i duplicate the 2 frames ( for the extreme slowmotion ) with adobe after effect cs5 ?

[DreamaginaryPictures]

@Eltura

Duplicating the 2 frames is necessary because in Premiere Pro plug-ins are not allowed to stretch or compress clips in the timeline. That might be different in After Effects, but I'm not sure... I think you can stretch the clip in After Effects by enabling Time Remapping (Layer -> Time -> Enable Time Remapping). There are also some tutorials explaining the application of Twixtor in AE.

[xLiiLT]

awesome man, the first tutorial that shows twixtor pro properly <3

[multimediaarts]

what the use of track points?

[Cartyy]

peace

[snostorm8]

really helpful, thanks! i'd never have guessed that was as low as 2 frames!

[DjEtnico]

Thanks for the tuto.

In the final render, the Extreme Slow Motion takes about 14 seconds. Have you uses 3 or 4 frames instead 2, or just have lowered the speed?

[DreamaginaryPictures]

@DjEtnico

I only used 2 frames, like in the tutorial. But I think I lowered the speed to about 0.14% of the original speed, which is REALLY slow and might produce serious blending artifacts if you don't use proper footage and correct Twixtor settings. Fortunately, it worked! ;)

[Maaxxwell]

Sehr gutes Tutorial, Danke!

@viragrenata2006

According to my Hungarian-to-German-translator you appreciate my video. Thanks for that! ;)

[vickyefffex]

i m just rendering a test after this tutorial.. thanx for explaining it in a simple way..

can u please tell me how to apply to selected portions of the video in the timeline..

so that the transition from normal spead to slow motion is gradually done. when i apply the time remapping it gets all messy .. i m stuck on it :( ur help will be highly appreciated :) Thanx

[DreamaginaryPictures]

@vickyefffex

I think you can just use key frames for the time attribute in Twixtor (similar to using the time remapping in Premiere Pro etc.), but I'm not sure how it will work with very slow motions like less than 10% original speed. Maybe the tutorial "Speed Ramp in Premiere Pro with Twixtor" at the RE:Vision website will help you (cannot put the link here, sorry).

[dimbo987]

@vickyefffex Add a keyframe at the current frame rate, add another key frame a few frames after and set this to about 10% then add another key frame another few frames ahead and set it to the desired %.
