AE Basics - A Creative COW series for new users of Adobe After Effects. Lesson 63: In this tutorial, Andrew Devis explains a significant 'under the hood' improvement in CS6 which reduces the need for 'Pre-rendering' and makes the operation of After Effects much faster. These improvements are called the 'Global Performance Cache' and the 'Persistent Disc Cache'. Andrew explains how these operate, options to use background rendering and the work-flow savings this offers.

Re: AE Basics 63: Persistent Disc Cache (CS6 & Above)
by Camille Katz
Hi Andrew,

Thanks for this helpful tutorial!
I have a question that no one seems to figure out so far...

Every time i bring in footage from my silly little camera into premier pro or after effects i get these weird lines and breaking up things in it.
The more footage i add to my sequence the more break up thingies i get.
And sometimes strangely enough they are different every time i play back.
When i view the same video in my explorer window i don't see it. What can be the reason for this? is it something with my premier pro settings?
Some members suggested i delete media cache settings, i did that but it didn't help. another one suggested putting a blank video underneath and i tried that but still it didn't change it. i even tried a transparent video and then a black video and then both but nothing helped.
I'm really upset as i want to make this movie but it just looks so aweful!
A week ago everything worked fine. I'm really confused.
I hope you can help me.

Thanks a lot!
Camille

Hi Camille

It looks like the footage has somehow got corrupted and may need to be re-linked.

In After Effects, in the project panel, right-click on the footage items and choose re-load footage. If that doesn’t work then you need to replace the footage with a solid or something else, then clean your data base & Cache (Preferences Media & Disc Cache) and maybe even empty your disc cache as well. Save the project with a new name and with the new settings and re-start AE.

Then, open the new project with the solids in place of the footage, right-click on the footage and choose Replace footage> file and navigate to the correct file for the clip and that should force a re-loading of the original uncorrupted file. (It should be simpler than this but as you are still having problems this is a more ‘belt & braces approach).

In Premiere Pro, go to your project panel and right-click on each of the clips and ‘Make Offline’. Then in the preferences go to the ‘Media’ tab and again clean the media cache files and the media cache database. Once again I would save the project with a new name (File>Save As) and re-start PP (belt & braces) – and open the new project.

Next, right-click on each of the footage items and choose ‘Link Media’ and navigate to the uncorrupted original file.

If this doesn’t sort the problem out for you I’m not 100% sure what else you can do except (and I probably should have started with this) export a short section and see how it looks and make sure if it is a real problem with the footage (in which case you will see the problem in the export) or if it is just a playback issue on your system (in which case you see the problem while using AE & PP but don’t see it when you export).

Hope this helps
Andrew

Lesson 12: In this second tutorial on the process of animation in After Effects, Andrew Devis explains how to make your animations look far better through the process of adding the appearance of weight to your assets. This is done through a change to your keyframes called 'easing,' which causes the keyframes to change their default behaviour to give much more realistic and real world animation. As well as showing how to add easing to your animation, Andrew also introduces the graph editor to show how to change the values of eased keyframes.
