Not sure the title is the best way to describe this, but essentially the motion of objects in my copy of AE is no longer smooth, it's as if it is dropping frames, almost every other frame, it's quite subtle, but it's not how it was a day or two ago...
All was well, until i watched back a RAM preview and noticed the objects stuttered across the composition rather than moved smoothly as normal. Thought it was probably just because it was a RAM preview, but uncompressed rendered versions suffered too.
Not sure if I have unchecked something, bumped my keyboard and used some shortcut to change a setting or what has happened. Have tried working at a few different composition sizes, all at 25fps. If I push up the frame rate to 60fps, this appears to sort it out, also if I put Frame Blending on, this helps it a little too. Is there anything else I should have turned on or off?
Playing back other video in Quicktime or VLC on my machine is fine, when I open older AE projects they appear to now be affected too. It's also having an affect on certain objects fading in and out using the opacity.
Any thoughts or insight would be much appreciated. Will upload a vid if needs be.
Cheers
