Twixtor working only with positive speed values, not negative

[James Harris]

Never had this but when I am tryong to apply Twixtor to my sequence it only works if the speed % is set to a positive value.
If I set it to something like -10 and hit play nothing happens and if I hit the preview ram button I get this error message:
“After Effects error: RAM Preview needs 2 or more frames to playback”

Any ideas on how to fix this problem?

Hey Dave,
The last I used AE and twixtor was 7 years ago so forgot a few details, picking up things again.

I don’t want to animate the speed of a clip I just want to slow it down (constant speed) in an elegant way without it being clunky.

I don’t like to use the native time remapping tool in AE because the slow motion effect is never as smooth and fluid as in twixtor, this is why I chose twixtor.

OK, to sum things up if one wants to have a nice slow motion effect here are the options:

1-convert from 60fps to 30fps + enable frame blending or use RS motion blur or use timewarp motion blur.

2-use time strech + enable frame blending or RS motion blur or time warp motion blur.

3-use simple time warp (enable built in blending).

4-use twixtor (enable built in blending).

PLZ corerct if I am wrong.
