I don’t think this can be done with native tools. I’d suggest Twixtor Pro from RE:Vision Effects.

You have to Interpret Footage on your UV pass and make sure it’s set to “Preserve RGB,” and you have to make sure the color depth of your project is set to at least 16bpc.

Preserve RGB tells Ae to bypass its color management system for a footage item, and the project bit depth governs the precision uses for storing images and calculating effects. This is important here because a UV pass is data, not an image.

We need to make sure the RE:Map effect can get access to the raw RGB values, and that it has sufficient precision to avoid distortion.

Specifically, the R and G values will be remapped from their native range to 2D coordinates in texture space (UV), so we want to make sure that no color or gamma processing is being applied to the original values, and that we have sufficient precision in the texture coordinate system.

Perhaps you are working on the speed graph, but thinking in terms of the value graph?

You can toggle which graph the graph editor shows with the “Graph type and options” button at the bottom of the graph editor. More here:

Ray-tracing is computationally expensive. 3 hours of render time for 25 seconds of animation is not unreasonable.

Depending on what it is you’re trying to do in 3D, you might be better off using the Classic 3D renderer and adding a third-party plugin like Element 3D or Stardust into your workflow.

Glad to hear it, Héctor!

You might want to keep those plugins around, just in case you need to move them back in to play some other kind of media. They are not part of the standard install, though, so you should only need them for something custom.

Other than pressing the Like button on a post, I don’t think there’s a way to mark an issue as solved.

Very likely so!

This looks like a codec pack from MainConcept. Have you installed any new software recently?

You might be able to manually remove the MainConcept folder from C:\Program Files\Adobe\Common\Plug-ins\7.0\MediaCore.

Make sure all your Adobe apps are closed, then drag that MainConcept folder of our MediaCore and onto your desktop. Relaunch Ae and see if it works better.

This is very fast and easy if you keep the same scrolling height and timing between elements.

Just set three keyframes for the Y position of your scrolling layer:
1) its first position
2) its second, scrolled position
3) a copy of the second keyframe

Then Alt+Click the Y position stopwatch and paste this expression:
loopOut("offset");

This will loop the position change, but each cycle of the loop will be offset, so the effect is cumulative and constantly building.

Quick sample project:
13338_scrollingfeed.aep.zip

In this example, I’ve recreated your text, but that precomp for scrolling could just as easily contain profile images, emoji, etc.

It sounds like Ae is trying to interpret MP4 files as a data source for data-driven animation [link], which it obviously should not be doing!

I’d suggest you try resetting your Ae preferences. Close Ae, then hold Ctrl+Alt+Shift while starting After Effects.

You could use a service like Transcriptive to handle the speech-to-text part:

Then use one of Premiere’s captions workflows to burn in your captions as subtitles:

You can resize the expression vertically in the timeline by clicking and dragging its bottom dividing line.
