After Effects preview delay

Hello, i realised when I put a reverb filter on my mp4 clip it delayed it, so I wouldnt recommend putting audio effects on mp4 files until you're ready to render. if anyone is having similiar experiences.

Hello derrick

Thanks for reporting the issue you are facing and we are sorry you are having a bad experience. 

A few questions/ suggestions we hare are:- 

1. What version of After Effects are you using?

2. Have you tried the latest After Effects beta build to see if that works better than the released versions of After Effects? You can download one from CCD if you look for the Beta apps. We ask this because we have made some improvements with the preview playback in the beta builds that might help you. 

3. Is this with a specific project or more of a general issue? If it is project specific, could you please share the project with us?

4. Can you please share the details of your machine on which you are encountering this issue?

5. Lastely, a screen recording of the issue might give us some clues if that is something you can provide. 

Regards,

After Effects QE.
