Trouble reopening a PPro sequence
on Jan 4, 2011 at 8:00:44 pm

I have a problem and I have no idea what is going on or how to solve it. I'm using CS4 for both PPro and AE and I have a Matrox RTx2. I captured my HDV 1080i footage in PPro and put it in the time line. Then I opened AE and imported that PPro sequence. I did some green screen stuff and then rendered it out. I decided to make some changes after seeing the full render and when I went to open the composition, AE tells me that the MPEG file is missing. When I try to import or replace the file AE tells me that it can't import "xxxx 4800.cfa": unsupported filetype or extension. (0::1). It brought it in once, why won't it do it again. How can I get AE to ignore the file and bring in the file I want?

Thanks

I hope you're not too far along in your project. I recommend capturing your footage in a different codec or transcoding it to a different codec. You've run into a problem AE 9 has with long-gop footage. Here's an explanation from the pre-AE 10 days:

Dave's Stock Answer #1:

If the footage you imported into AE is any kind of the following -- footage in an HDV acquisition codec, MPEG1, MPEG2, AVCHD, mp4, mts, m2t, 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.

I'm a Mac guy, so I like to convert to Quicktime movies in the Animation or PNG codecs; both are lossless. I'll use Apple's Compressor, Adobe Media Encoder or Quicktime Pro to do it.

Dave,

That make sense to me but why can I import the PPro project and everything works perfectly, I save it, close it, reopen it and THEN it gives me the can't read it/don't understand it error messages?

That's AE freaking out, causing a wide variety of problems, man. Once the software spaces out, there's no logic behind it any more.

Thanks Dave,

I'll just use your method until I get CS5 at the end of the month.

Remember: CS5 is 64-bit!

Buy any plugins for AE? You'll need new 64-bit versions.

You thought AE was a RAM Hog before? You ain't seen nothin' yet! I have a dual quad-core machine at home, primarily for work in AE 10. It has 24 GB RAM on it, and if I could have afforded more, I would have gotten more.

Caveat Emptor! Before you run out & buy it, scrutinize the Adobe web site to get the straight skinny on system specs! Read Todd Kopriva's AE blogs!

Dave,

No problems here, I'm already running 64 bit and my new system that I'm getting will be that too. I just spent a couple months specing out a system. Luckily the corporate stuff I do isn't too intense. I just run into these little problems once in a while.
