I cant import Mpeg2 files into After Effects CS4 on my computer, I get the 86::1 error.

I can export/render them.
I can import them on my colleagues computers who all have the same version on almost identical computers.

This is a Mac, the file type is Mpeg2 (MainConcept MPEG) 25fps, Progressive.

It seems strange that all the other computers are fine and the fact I can export the file just not import!

Any help appreciated.

Can you open Mpeg2 files into Premiere Pro CS4 (if you have it on this machine)

Hi Graham,

I have just tried importing the same file type to Premiere on the same machine and I get;

"File Import Failure; File video dimensions (width/height) too large.

...and as per After Effects I have tried importing the file to Premiere on my colleagues machine and it imported with no problems what so ever.

Perhaps the file extension is confusing AE/Premiere.
Have a read here:
http://kb2.adobe.com/cps/406/kb406350.html
In section: MPEG-2 (MPG, M2P, M2V, M2P, M2A, M2T)

Are your AE / Premiere installs fully updated to the same point as the other machines you tried?

AE and premiere do tap into the OS for additional codec encode/decode capabilities. So if it were an issue with a non standard codec like Xvid for example I would suggest that the codec might be damaged or in need of updating. However, AE and Premiere are supposed to support MPEG-2 natively. Perhaps instead you have an MPEG-2 codec variant of some sort (maybe came with some DVD player software) installed on your machine which AE/Premiere are trying and failing to utilize? Not sure if this is possible on a Mac (I'm a PC user) so perhaps someone else can offer further insight.

[Ryan John] "I cant import Mpeg2 files into After Effects CS4 on my computer, I get the 86::1 error. I can export/render them."

Wait a minute: if you can't import them into AE, how can you export them out of AE? I guess you're talking about exporting out of something other than AE.

Well, here's the bad news: you're still running AE 9, which has a problem with footage that AE 10 pretty much eliminated. So the following still applies:

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.

---------------------------------------------------------------------------

Since you also talk about the dimensions being too big, this file could also have come from or was destined for a Blu-Ray disc, and AE 9 wasn't equipped to deal with them -- only SD Mpeg2. You'll also want to be sure you have the latest update to AE 9, which came out AFTER Adobe released AE 10. Here's a link:

If you're not on a Mac, there's also a Windows version you can track down.
