Twixtor in AE question

[Tero Ahlfors]

If it’s only 8 frames you could also trim them.

Does changing Output Control > Speed % to 104 work?

[Karel Bata]

Nice reply, but the actual figures yield a less simple fraction.

This is for a stereo 3D timelapse where the cameras didn’t run in sync. I’ve figured out a solution, which is below.

You add a solid layer and apply twixtor. Source to source footage. Original frame rate. Select Output control / frame num.
Go to first frame and click keyframes, which should add one.
Go to where you want the final frame. Type in the frame number of the source material you want to end up there.
That’s it!

There sees to be an option to enter frames that are ‘between’ frames, like frame 12.5. If so, this should help address my issues with sub-frame sync.

why don’t apply it to the actual footage? why do you need the solid?

That’s how Twixtor works. Don’t ask me why…

[Roei Tzoref]

my question wasn’t clear. I meant, did you try to put twixtor on the actual footage? that’s how I do it. and I usually use frame manipulation and not speed. for slow down or speed up.

Ah. Maybe it’s changed. That used to be the only way it worked.

[Roei Tzoref]

could you try putting the effect on the footage instead of the solid and tell me if that works? I am curious.

I don’t get what you did.

I can see why maybe you’d object to using a solid layer, but think about it. If you didn’t have a layer that was the effect output where would you put any keyframes for changes of speed beyond the end of your source layer? Or markers? You put them in the original video layer?

Imagine then that you’ve slowed down a one minute sequence by 50% to two minutes, but you want to keyframe a speed variation at 50 seconds. Where would you put the keyframes for that? In your timeline you’d get to the end of the source footage at one minute with nowehere to put the later keyframe.

[Karel Bata]

Damn. There’s a typo there and no way to edit. Substitute this for the last paragraph in the previous post:

Imagine then that you’ve slowed down a one minute sequence by 50% to two minutes, but you want to keyframe a speed variation at 90 seconds. Where would you put the keyframes for that? In your timeline you’d get to the end of the source footage at one minute with nowehere to put the later keyframe.
