Running AE cs3 on WinXP.  I just installed the new 1.8 codecs and now I ma having serious crash problems working in 16-bit color space in After Effects.

I have a dnxhd clip (specifically I am using 23.976fps, 720p, 90)

If the AE settings are set to 8-bit I have no problems at all, as soon as I click that 16-bit button it crashes.  Also, the session can be in 16-bit as long as I'm not viewing a dnxhd clip.  As soon as my marker hits a dnxhd clip, it crashes.

 Anyone else?

thanks

I'm not an engineer, so I'll play dumb, but ARE the DNxHD codecs 16-bit?  I didn't think they were.

Did this setup work with the older versions of the codecs?  Do other 16-bit codecs also cause AE to crash?  (AE CS3 is not known for stability yet.)

I don't believe the bit-depth of the codec has anything to do with the bit-depth of an AE project.  I can use any codec on my system in a 8, 16, or 32 bit AE project.

I could not stop the crashes at all, and in the end I had to manually go into my quicktime directory:

C:\Program Files\QuickTime\QTComponents

and remove the Avid components manually.  Then I re-installed an older version of the codecs and everything is fine.  I do a lot of color correcting and budget "onlining" (as it were) in After Effects in either a 16-bit or 32-bit sessions.  So it's essential that I be able to bring the clips in.

Thanks for replying, I thought my post would be lost into the abyss ;)

If I get a chance myself, I try it this week.  If I also can get it to crash, I'll report it Engineering.

I haven't used AE CS3 much myself, but I have heard it's buggy.  Do you hear anything about other codec issues in the AE forums at Adobe or Creative Cow?

Nothing specific, but I'll keep a look out.

I have been using cs3 since about when it came out, and I haven't had too many problems.  In any case, thanks for the help.

Where you able to get the same results as I did?

Sorry, haven't had a chance yet...I'm in the middle of a two-week edit.  That ends Monday, so I'll definelty get to it early this week.

Yup, I'm getting 16 bit crashes in AE after installing new Avid codecs too.

Sean, thanks for confirming this.

What do we do now??

Anyone else?

I seem to be able to convert all non-Avid DNxHD files to 16 bit and 32 bit in After Effects CS3. But cannot convert the DNxHD files to 16 or 32 without getting a crash in After Effects. This problem seems to coincide with upgrading to the new Avid codecs.

I reverted to After Effects 7.0, and the issue with the DNxHD/Avid QuickTimes went away.

So there seems to be a conflict with the new DNxHD 1.8 codecs and After Effects CS3 that causes direct a direct crash.

Sorry about the delay...I will forward this to Avid engineering ASAP.

Some PC users have experienced problems not just with DNxHD codecs but all QT codecs crashing any app that accesses them. For these users a common fix is the following Answer on the KB.

Give that a shot and let us know if it fixed the problem.

Hi,

I switched Quicktime into Safe Mode and, unfortunately, it did not fix it.  AE CS3 still crashes in 16 and 32-bit modes with the new DNxHD 1.8 codecs.

Thanks
Lucas

Do the DNxHD 1.6 LE codecs have the same problem? I noticed that the 1.6 codecs were not available so I created an answer and attached the 1.6 LE installers.
