    Rendering to PNG error

    Mr. Zogg Level 1

      A problem cropped up after switching to After Effect CC 2014; grabbing a frame as a PNG file fails with this error message: "AEGP Plugin PNGIO support: PNGIO library error: known incorrect sRGB profile ( 5027 :: 12 )"

       

      So, what the heck is that supposed to mean and how do I fix it?

       

      Thanks

          I have the same problem... anyone know how to solve this? Thanks

            Neither of you has provided any proper technical info like system specs, render settings and whatnot, so no, nobody can even begin to guess.

              OK MR. Mylenium, fair enough. As mentioned above, I'm using After Effects CC 2014 (v12.2), on a Mac (OSX 10.9.5), the problem comes when trying to render a frame as a PNG file. The error message itself seems pretty specific. What else did you want to know?

                Haha, yes indeed... Ae CC 2014 (v13.0.2.3) MacOS 10.8.5, and as Mr Zogg mentioned, the problem comes from trying to render to a PNG frame/sequence... in my case I've got a cinema 4D lite file in after effects and am trying to render out the animation as a PNG sequence. (sRGB linear colorspace seems to have something to do with it?) I can render to Quicktime no probs, its just something to do with sRGB not working with the PNG export... which is a pain because thats the best way to export animations with transparency.

                 

                thanks for any thoughts.

                  Seem odd no one is aware of this bug or how to remedy it.

                    I don't know how to fix it because it's working fine on my system.

                      Well, fascinating Rick. Is your system different in any way from the affected systems described above?

                        Can you render to QuickTime with the PNG codec?

                        Can you render to QuickTime with the PNG codec with alpha?

                        Can you render to QuickTime with the Animation codec with alpha?

                          There's no such thing as "QuickTime with the PNG codec", so no.

                          Animation codec with alpha is no problem. Did you read the earlier posts?

                            Yes there is.

                            In After Effects, choose QuickTime as your format and then look at the codec options you have. PNG is one of them (as is Animation, Photo JPEG, and many others). PNG in a QuickTime container like that is a great way to render a video file with alpha. Granted, an image sequence outside of a QuickTime container is usually a good idea with long renders, but I was suggesting this as a troubleshooting step to try to see where things were going wrong.

                            That wasn't specified in the previous posts. Nobody said what codec they were using or whether they were getting alpha; they just said, "QuickTime is working".

                             

                            If rendering a QuickTime with alpha is working, a short-term solution would be to then use the Adobe Media Encoder to create the PNG sequence from the QuickTime while we try to troubleshoot the underlying reason that AE won't render a PNG sequence correctly.

                              Szalam - The "PNG" option under Quicktime in AE renders a numbered series of PNG stills (without alpha), not a Quicktime mov. BUT, curiously, it DOES WORK on my system. So it is a possible, long-way-around, workaround. I get the error when trying to save a frame, under "Save Frame As > File" Under the "Composition" menu.

                                What happens if you try to save a PSD instead of a PNG with Save Frame As?

                                 

                                Also, double-check your settings against mine:

                                renderqtpng.jpg

                                 

                                When I use these settings, I get an MOV.

                                  Maybe a Mac>PC difference? Note alpha depth is greyed out, and as I said, this renders a still series.

                                    Under Channels, you have to pick RGB+Alpha to get alpha options (not the most straightforward way for that choice to be presented, I'll grant...)

                                     

                                    I would be inclined to believe it was due to a PC/Mac difference except that I know people on Macs who use QuickTime with the PNG codec...

                                      OK, that does render a .mov, with alpha. But weirder still, I could also render using, "Save Frame As > File" Under the "Composition" menu without any error message.

                                       

                                      So, maybe it's just miraculously cured itself.

                                       

                                      I think I'll go back to where the error originally occurred and see if I can replicate it.

                                        Maybe your QuickTime was hoping to get off early on a Friday?

                                          I'm having the same problem, and I'm not amused.

                                           

                                          AE CC 2014 (13.0)

                                          2012 MacPro running OS 10.9.5

                                          Working in 16-bit sRGB color space

                                          Outputting a 36-frame 1080x1080 PNG image sequence as client specified.

                                          Error message "AEGP Plugin PNGIO support: PNGIO library error: known incorrect sRGB profile ( 5027 :: 12 )" followed by "AEGP Plugin PNGIO support: Unable to create PNGIO. ( 5027 :: 12 ) appears regardless of whether I'm rendering millions of colors+ or trillions of colors+ or no alpha.

                                          Tiff sequence with same settings outputs fine.

                                          The same PNG settings output fine in AE CS6 (11.0.4).

                                          The same PNG settings output fine in AE CC (12.2)


                                          Since we're spending $50/month for this stupid cloud subscription I thought we might as well start using these CC versions.  Installed Premiere Pro CC 2014 for a simple editing job, but it wasn't compatible with Lion, so I upgraded to Mavericks (after cloning my system drive, of course).  AE CS6 then wouldn't open, so I moved my project to AE CC 2014 (not the most recent buggy one).  Got these PNG errors, so I've updated CS6 which now will open on Mavericks and has no problem outputting my PNG sequence.


                                          Weak.  Guess I'll submit a bug report.

                                              My first course of action when encountering a problem like this in the past would have been to upgrade to the latest version of the software, but given the issues with Unmult and other bugs I'm reading about I'm not exactly champing at the bit to update to the October version of AE.

                                               

                                              The frustrating thing is I can render PNGs in two other versions of AE I have on my system.  Why did it break in CC 2014 (13.0)?  It really doesn't seem like things have improved much since being forced to move to a subscription plan, despite all the talk that the developers would now have time to work on those little improvements that couldn't be addressed when working under the tyranny of having to generate new, exciting features for annual releases.

                                                      Broke here too... Yosemite with AE 13.2. Worked fine before in older versions. It seems tho that if you go back to an older project were you have saved this preset as an output template, you can get it re-saved back into the global templates, and use that. That worked for me eventually, however I could see no differences at all between the old png sequence render settings and the new. I also think it's strange that in this new version, PNG Sequence has been removed from the output templates. Why is that?

It successfully found the first few files but then came up with the error message. Not only this. I tried just importing the PNG files with no success. Also, when I tried to Replace a WAV file in the same project it comes up with the same PNG error message! That's insane.

                                                         

                                                        Quickly tried to open the project in AE CC (12.2.1.5) and the same error comes up with the PNG files.

                                                         

                                                        I'm going to investigate and see if there is anything different about those PNG files, but the way it is screwing with the Replace function on other file formats suggests a deeper glitch that needs urgent attention.

                                                            This is a very troubling problem.

                                                              Blaink, is there a reason you're not running the latest AE (13.2.0.49)?

                                                              Also, can you render a QuickTime RGB+A with the PNG codec? (This is a PNG sequence in a QuickTime wrapper with audio.)

                                                                I don't know about Blaink, but the QT RGB+A and PNG codec route works for me. Just the PNG image sequence output itself.

I'm getting exactly same error messages when I try to render out PNGs. I realised that when I'm using sRGB as Working Color Space, it will fail. I can always use Adobe Media Encoder to export PNG sequences (it works), but it would help a lot and make thing easier, when just trying to export some simple still images with Alpha channel.
