Twixtor Clips
Erwin Beatz
So I'm making a Call Of Duty edit, but I'm having an issue. I have applied Twixtor Pro to sync the clips, I slowed down the clips to 30% speed, but the issue I'm having is that the actual clips stops before the footage does, (example picture below). Please help me fix this because this edit is going very well and I really do not want to scrap it. Thank you!
I never apply Twixtor to a movie, I add it to a solid and select the movie layer as the source. That way you can slide the in and out point of the twitter layer around as much as you like and not have the problems you are having. Twixtor requires training. It's far to complex of a 3rd party effect to just jump in and start wiggling the knobs.
You have to pre-compose the clips to a longer comp and apply the effect to this pre-comped layer. As Szalam said, it might be useful to actualyl read the help for Twixtor. Effects cannot extend layers, only AE's native time-remapping can.
Hello once again. Few days ago, I have come across a weird problem / glitch / crash that occurs that has never happened before. In an After Effects project that I am doing, I am planning on making the boomerang effect. Basically, I want to put slow-motion to a clip and then duplicate it, and reverse the duplicated layer, to give it an effect similar to boomerang. But something weird happens every time I do so. I want to give boomerang effect to different parts of a video, with the frame rate of 23.978. So in my first clip, I would pre-compose it, put twixtor pro to it (I put the frame rate of the video as it is in the twixtor, which is 23.978), then pre-compose again. Then I duplicated that pre-composed layer with twixtor inside it. I moved it right next to the 1st layer, and then I what I did was : right click > Time > Time-reverse layer. It worked perfectly fine. But then, I cut to another part of the video to make the boomerang effect with and also to put twixtor. So I did the same exact steps as before to the 2nd clip. Pre-compose, add twixtor (I copied the twixtor effect from the first clip and pasted it to the 2nd clip), pre-compose again, duplicate it, move it right next to the original layer, and then right click > Time > Time-reverse layer. But in the few frames at the end of the reversed second clip, it has a warping and mixing from the first clip.
These pictures of flowers are the example of the video I used few days ago. Please pretend that it's a video with 23.978 frame rate, as I cannot use the original video due to privacy reasons, but what is shown in the picture is exactly what is happening.
I Have tried everything I could. I cleared the cache of After Effects, I put the twixtor individually and manually without copy pasting it from the previous clip, I put the preview resolution to Full, I updated my graphics driver just not so long ago, I pre-composed 2 times before reversing, playing with the other options in the twixtor pro effect controls, choosing "blend" instead of "motion weighted blend", changing the frame rate number in the twixtor option, re-installing the twixtor plugin, I tried everything I could yet it still comes back and it still remains there no matter what I do. I need serious help, please. This is really stressful and I need help or solution please.
I never apply Twixtor Pro to a nested comp (pre-comp) or a footage layer. Try adding a solid, add Twixtor to the solid, then point to the source footage in the Effects Control panel. You can then turn off the original source footage layer. Adding Twixtor to footage is just asking for trouble.
Hello, sir. What do you really mean by pointing the solid to the source footage? I have added a solid with black color, put it above my footage (not pre-composed), then set the Alt Color Source and Alt Motion Source to my footage but it only made it have a color red on the footage.
You have to apply the effect to the clips individually. Twixtor, when applied to a nested sequence or precomp treats the video as one solid block which means it will try and figure out the frames between cuts. This leads transitions to warp from one shot to the other.
Well, place a keyframe of 100% at time 0, and another keyframe of 100% at time 199. Then the clip will be forced to play at 100% for the entire set of frames up to 199. THen change the speed to 33% at frame 200.
If you set the in-point in premiere for the clip, note that Twixtor stills thinks frame 0 is the initial in-point with regards to frame 0. Since you already needed to make s nested sequence to make the sequence longer what you should do instead is slide the clip in time in the nested sequence so the first frame is where you want to start the retimed version to be.
Just tested this. Yep, it seems that in Premiere, you must nest a clip for twixtor to work at the desired edit point. While in FCP7, you can just apply the filter, and it will twixtor from the edit point without the need to nest.
when i apply the twixtor filter though, the quality of the image immediately drops and i see jagged edges all over the image. it looks like twixtor drops half of the quality of the original image to do its task.
Usually, to get smooth slow-motion footage, you need to shoot at a higher frame rate in-camera. Most often, videographers will shoot at 60 or 120 frames per second when they know they want to include slow motion in their project. This high frame rate footage is then played back at either 24 or 30 fps, depending on the production. Capturing more frames and then playing them back at a slower rate is an effective way to create a cinematic slow-motion effect.
When you use your editing software to slow down normal frame rate footage, it has to make up for the missing frames somehow. To do this, it guesses what those missing frames would have looked like based on surrounding frames.
Twixtor claims to be particularly good at this interpolation process. The plug-in uses proprietary technology that tracks the motion of each pixel. They claim this results in more accurate filler frames with fewer weird digital artifacts.
In addition to retiming footage on a percentage or frame-by-frame basis, Twixtor offers several other features, like retiming 360 video and converting footage between different frame rates. The plug-in can also be used to add motion blur and enhance dark imagery.
Next, add the clip you wish to slow down to the newly created sequence. Copy and paste the same clip into your Twixtor Slo-mo sequence two or three times. This extends your slow-motion sequence, so nothing gets chopped off once you slow down your footage.
In this case, we want to play back our footage at 50 percent or half-speed. That means I need to set the Speed % value to 50. If we wanted the clip to play back at quarter-speed, we would set the value to 25 and so on. Choose the playback speed that works best for your specific clip.
From there, you can tweak your setting according to your footage and needs. Try different playback speeds and experiment with different quality settings. Also, note that some clips will be easier to slow down than others, so subject matter and type of movement will impact your end results.
Overall, Twixtor is a useful tool for professionals who need more options when it comes to retiming footage. It shines when tackling more complex tasks like keyframed-based speed ramping but can also be useful in producing fluid slow-motion footage in a pinch.
