Hey Dave you recently responded to another post I had about a strange video freeze happening within AE. Well. I took your advice of exporting the videos out with a different codec because they were either originally saved out as H264 or Mpeg 2. I went ahead and re-exported the video clips with "photo jpeg" as the codec and it does the same friggin thing! I keep adding to my project and everything seems to preview fine within after effects until boom! I add one more clip to the timeline then all of a sudden the other clips within the project all freeze like still frames in the middle of a render. Very odd. Can you help me further?
Here are 2 links of my setup. In the second example, im just showing u how ive added the videos.

You may be plain ol' runnin' out of memory!
I see your stuff is 16x9, which can mean SD or HD. If it's HD, that's a TON of pixels for AE to deal with, especially if you only have something like 2GB to begin with.
Try setting AE to do a purge after 10 frames or something (Shift-Preferences, select Secret).
....OR....
You can do prerenders on all those little picture layers. Cuts down on a lot of pixel crushing, y'know....

In FCE 4 I simply exported my video as a self contained video. From there I've imported that into AE.
I've also tried videos I've already made and compressed in the past by reconverting them to another codec like photo jpeg. still seems to happen though.
The project seems to work out okay in the beginning until I get to a certain point....then everything ive done to that point freezes...very very odd.

Aw, jeez, that means it's HDV. Re-read the following CAREFULLY:
Dave's Stock Answer #1 For Current Footage Woes:
If your source footage is any kind of the following -- Native HDV, MPEG1, MPEG2, mp4, H.261 or H.264 -- you need to convert it to a different codec.
These kinds of footage use temporal, or interframe compression. They have keyframes at regular intervals, containing complete frame information. However, the frames in between do NOT have complete information. Interframe codecs toss out duplicated information.
In order to maintain peak rendering efficiency, AE needs complete information for each and every frame. But because these kinds of footage contain only partial information, AE freaks out, resulting in a wide variety of problems.

Dave I realize this. It's telling me to convert my HDV footage to another codec....which is what I thought I was doing when I exported my video to photo jpeg codec...sometime this week ill try and do a screen capture video for you and send u a link so u can see what I am doing. It may help more if you actually watch how I go about it. Im not sure how else to describe or fix what is happening.

If you hold down the Shift key before you go into preferences, a "Secret" menu appears at the very end. This gives you the chance to disable layer caching and purge memory after a certain number of frames.
This can add a bit of time to a render, but may mean that After Effects is able to render out something that it's struggling with.
Shhhhecret.
Good luck,
Ben

This does not seem to work for me. Im on a mac. Not sure if this has anything to do with it. i go up to preferences and before I push it, i hold shift then click on preferences but nothing seems to happen...
Re: ATTN: Dave LaRonde by Darby Edelen on Apr 8, 2008 at 11:12:28 pm
You need to hold shift from the time you click on the 'After Effects' menu until the time you've clicked on the drop down menu inside of preferences (it starts out saying 'General'). This works on Mac or PC, doesn't matter.
