Time remapping video - why doesn't it render?
on Aug 13, 2019 at 5:45:13 pm

Hi, I time remapped a composition in AE 6.0 but when I go to render the part of the composition that I want to use in my edit none of the time remapping effect goes into the clip. I know I'm probably missing something basic - maybe because I'm rendering as Pro Res LT and not as Animation?

Any help would be greatly appreciated.

Thanks,

Rob.

To a PNG sequence? I've never had to do that before, could you explain it to me?

Make sure you enable the frame blending switch for the footage layer inside the precomp's timeline.

Thanks for the advice. Where is the frame blending switch and what is its relevance? Perhaps you could tell me, is it better to time remap footage or footage within a composition? I've watched a couple of tutorials on Youtube and they nearly always remap the footage not the comp.

[Robin Fearon] "Where is the frame blending switch and what is its relevance?"

Here's the frame blending switch:


If you leave frame blending OFF, time remapping will not create any new frames from the source material. For example, if you're remapping 2 frames to 4 frames, Ae will hold the first original footage frame for two frames, then the second original footage frame for two frames.

If you enabled frame blending, Ae would synthesize new frames in between the originals, giving you smoother motion (but the possibility of noticeable artifacts).

There are two frame blending modes: frame mix (which dissolves the two adjacent source frames together, with emphasis given to the frame that's closer in time), and pixel motion (which analyzes the motion in the existing footage and attempts to interpolate that motion to the in-between frames).



[Robin Fearon] "Perhaps you could tell me, is it better to time remap footage or footage within a composition?"

It shouldn't matter technically. I'd say do whichever is easier to keep organized in your project.
