Animation rendering issue, unknown error

Support and Advice General Questions
1

Hi everyone,

I have some trouble with the rendering feature.
I’m using the latest version of Krita and FFmpeg, although when I try to render a window pops up saying that the rendering failed for an unknown reason.

It did work a time or two but since then nothing.
As I’m currently in the making of a short animated film, I desperately need to find a solution!

I tried exporting the animation as images, but even with 14 frames, it’s just not productive.

So I hope to find an answer here!

Thank you in advance,
Have a wonderful day,

Athena-

Which OS are you using? Are you using Krita 4.2.8?
Did you get version 4.2.2 of ffmpeg via the ffpeg.org site?
Are intermediate .png frame files produced in your target folder?
If it worked for a time or two before, what is different about the situation and the animation now?
Is there any kind of ‘encode’ log file produced in your target folder? If so, can you provide it for examination?

Hi, thank you for the quick response!
(I apologize in advance if I answer aside from the questions, English isn’t my first language)

I’m using the Windows 10 pro edition, version 1909.
The version I’m using of Krita and FFmpeg are indeed 4.2.8. and 4.2.2. I’ve read that it might be too new for the software to work, but I can’t seem to download past versions.
I can render the animation in .png without no problem, but it seems that the issue only occurs when a video file is at stakes.
Well, the times it worked, it did as the program would normally.
The other times, so 99% of the time, an error window pops-up saying, I quote; “Could not render animation; Unknown error.” And export everything as .png files.
It does not seem to matter whether I change the frame rate or the number of frames.
It does! here it is:
(could not figure how to add the file in itself, so I’m just gonna copy/paste it)

Hi, what size your animation is - what size is your canvas, how many drawn frames you have (count all filled rectangles, which means if you have several layers then sum all rectangles in all of those layers) and how long it is (here 14 frames, right?). How much RAM do you have and how much Krita can have (this can be seen in Configure Krita → Performance) and how much RAM is used (see the bottom bar - but this you need to check when the render fails, not when it succeds).

Hi,

I’ve looked into all of them, my RAM, and Krita’s. (There’s way more space available than the actual size of the canvas)
Everything is set up right, I tried rendering in Clip Studio and it works just fine, I think it’s a Krita issue.
(I could use Clip but I really don’t fancy working on it)

There’s only 14frames, it’s just the rough line so just one layer.

In a situation like this, specific detail is needed to help work out what the problem is and where it’s happening.
Please provide the information that tiar listed, in numerical detail.

Can you also provide details (ideally in a screenshot) of the exact contents and values in the Render Animation window that you use before this failure.

If possible, can you also provide a download link to the .kra file that gives this problem?

Hi,
I understand, here they are :

I would like to add if it can be of any help, that it seems like above 14 frames it won’t render.
After I’ve set the ram memory to the “highest”, I tried again and it worked. I tried with 45 and it failed. (45 = 2 repetitions of the animation)
I even tried rendering into my other disk but it failed.

Btw, crazy suggestion, but something I did last time: can you please try rendering 45 frames after setting Krita to only use like 2GB? (in Performance -> Memory Limit. But don’t make File Size Limit smaller.)

The idea is that ffmpeg (which is a different program from Krita) needs some RAM to render it as well, so Krita will only use SWAP, and ffmpeg will use RAM.
EDIT No… it cannot be ffmpeg fault, because often ffmpeg doesn’t even have a chance to work on frames before Krita gives up on saving frames. It must be some bug in Krita that makes it use RAM outside of what is given to it. When you’re already doing RAM-heavy work, Krita takes the whole assigned RAM, so if it needs to put some more stuff outside of assigned RAM, it only has how much is left for the system…

Please tell me if it worked. (And if not, how many frames have you managed to render). Make sure to restart Krita before trying to render, and only open this file.

Is it too early to say I love you?
Because you literally saved my life right there !!

Thank you so much to both of you !!

Good to know! :smiley: I had to render a huge animation some time ago and it turned out to be a good way to do it as well. There is a way to deal with even bigger animations that even after changing to 1-2GB won’t render, but it’s tedious.

I think I might want to write a guide how to deal with and render something big, because there are a few culprints that need to be written down. For example, the File Size for swap needs to be big, as you did. What else might be beneficial is unchecking “Enable background cache generation” - it will save you some performance while working on it.

Also I believe the reasoning I presented above is wrong… I believe it’s Krita messing things up, not ffmpeg.

It’s good to know it’s working for you :slight_smile:

The RAM allocation of 14GB out of 16GB is too high though.
With a freshly started Windows system, if you run krita then the total RAM usage is 2.3 GB (Windows plus the Krita application before it starts to use RAM for its own image and animation work).

I’ve just imported the .mp4 animation that was made and for some reason the Animation Importer plugin would not go past frame 35 (another investigation needed) but I padded it out to 45 frames with duplicate frames.
After that I saw total memory usage of 4.2 GB (Image 2.1GB pool 2.1GB).

Having done that, I could render it out to .mp4 with no problem and I noticed that for a short time there was ffmpgelink (some link/calling process) using 2GB of RAM. So at least 4.3 GB (preferably more) of RAM needs to be available for use outside of that allocated to krita in its settings.

It would be interesting to know if Athena can render ok if the RAM allocation is taken down to 11GB or maybe 10GB, on that basis.

Athena is also running 6 clones and has the animation cache in-memory, all of which will push up krita’s RAM use until it may hit the OS, the application itself and ffmpeglink when it’s being used.
Having said that, it does sound unlikely based on the guidelines (tool tips on hover) for those factors.

It is a complicated subject and any guidelines would of course be welcome if it’s possible to do that.

6 clones is fine for 6 cores in the processor. It makes it faster to work… at least on normal-sized animations.
And in-memory is less buggy. On-disk often cause issues for some reason, not sure why, especially with opacity keyframes.
Also I don’t really understand this:

But just in case, Krita should never use more RAM than in the limit; when it needs more, it should use Krita’s SWAP file. That’s why this worries me because it proves Krita uses some of the RAM that should be left alone :frowning: and complains about out-of-memory when it runs out of it, even if there is a SWAP file available…

19

As I said, I don’t think Athena should have had problems with RAM headroom clash. I’ve just adjusted my settings to more or less the same as hers were (except that I only have 8 cores) and after rendering, the total RAM usage for krita was 9.6GB which is roughly 8.5 GB for image storage plus animation overhead.
If the RAM allocation is too high and krita does use it all, or most of it, then the OS itself will not be able to carry out krita’s own swapping out (writing to the swap file) since the OS will need RAM for data block buffering and file management while it tries to do this and then falls over.

This did happen before when someone had a PC with 4GB of RAM running Windows and krita (and a browser) and was then surprised when his computer crashed after an animation got close to 2GB of image RAM used.
