RAM Preview works but render doesn't
on Sep 23, 2015 at 6:21:49 pm

Hi everyone,

So the problem happened when I tried to render my video in AE CS6. Everything works fine when I play it in RAM preview, however when I press render some part of the video just doesn't move. What I mean is the animation of that layer just completely disappears. What weird is with the same layer the animation later on is fine.

Can someone help me? I'm desperate.

If nothing else, you can save the RAM preview as a file.

It sounds like you mistakenly set the layer in question as a Guide Layer -- they show up in the comp, but they don't render.

AE's default lossless output module generates an intermediate file that is designed for additional post-production use, not direct playback. These files are generally huge, with very high data rates, and very few computers can play them back in real time without stuttering. For more, see this Adobe FAQ [link]: Why is my output file huge, and why doesn't it play back smoothly in a media player?

To help you choose a more suitable format for your needs, see the related Adobe FAQ [link]: What is the best format for rendering and exporting from After Effects?
