An image sequence is much better than the mp4, which is highly compressed. AE has to do a lot more thinking, and the rare error has been known to occur.

But if you track QT movies in the PNG, Animation, Photo JPEG or ProRes codecs, there's no problem -- they used a different kind of compression, which requires a lot less thought from AE.

Hi Dave, I'm not I understand your explanation in the first sentence. I'm not a pro and use those programs as a hobby but try at least to learn to do it well.
What do you mean by "An image sequence is much better than the mp4".

For instance I have the following shot: It is a long zoom from the middle of one of the streets of Pompeii. I intend to give the impression that the buildings on both sides of the street return to their original look before the Vesuvius eruption. For this I have still image (png) of the walls etc.My clip is a 20seconds mp4 with theses characterics:
<a href="https://images.creativecow.net/282881/screenshot_wed_apr_20_09.30.35.png"><img src="https://i1.creativecow.net/u/282881/screenshot_wed_apr_20_09.30.35.png" border="0" /></a>

Do you mean that I should transform the clip into a sequence of 500+ single images? How do you that? The question may look silly but I don't know the way tot do it. Thanks

It is a simple export setting from AE. Yes it will create 500 (x) images per frame so make sure you have them going to a folder and not to your desktop which I have done more than once :)

Then when you want to import the sequence into your editing program make you sure you have import image sequence box checked or you will only get one frame.
