Subject: [AE] Problems (bug) with EXR sequences
 
Hi all,

I=92m having some serious performance issues with EXRs and I thought I=92d = check to see if anyone else could help.

I=92m working on a fairly big project, all renders are supplied as EXR sequ= ences with lots of channels.  I=92m working in 32bit float, linear. I have downloaded the latest Open EXR plugins from the fnord website (Hey B= rendan!  You there?) including Cryptomatte, which is a core tool.

After Effects will work with a single EXR file quite well.  Surprising= ly well.  If I import an EXR it opens and displays as quickly as any o= ther format.  If I use the ProEXR make comps feature (100% awesome) th= en it takes about 8 seconds to extract all the channels and display the contact sheet result.  Cryptomatte and Extra= ctor work very quickly.  So basically - if I have a single exr frame i= n After Effects then all works fine.  Cryptomatte alone has the potent= ial to be a complete game changer...

But as soon as I import an EXR sequence into AE then it all goes horribly w= rong.  Using the Pro EXR make comps feature now takes several minutes.=   Using Extractor to isolate a channel from the EXR now takes 30 - 60 = seconds per frame.  In some cases AE can take 5 - 10 minutes to show an image.

And here=92s the thing - this is for exactly the same exr file.  If I = manually import just the first frame of a sequence (or any frame) then one = frame is great.  As soon as I work with an exr sequence then everythin= g becomes almost unworkable.

It=92s probably cache related.  Yes I have the EXR cache enabled, but = I have a suspicion that AE is wanting to cache every channel of the entire = sequence before it displays a single frame.

I=92m about to make a screen recording of this for Adobe, as this is a sign= ificant problem for me and the project I=92m on now. 

Any suggestions?


-Chris
